Description

Electronic device for checking the charge level of a battery and its operating method

The present disclosure relates to an electronic device for checking the charge level of a battery and an operating method thereof according to one embodiment.

Recently, batteries (e.g. lithium-ion batteries) have been used in various industries including portable electronic devices and electric vehicles due to their advantages of high energy density and long lifespan. However, batteries cannot be charged and discharged indefinitely, and batteries age and their usable capacity decreases depending on temperature and charge/discharge cycles. As battery usage increases, the importance of safe and efficient battery management is increasing. The battery state-of-health (SOH) is an indicator of the battery lifespan. The battery aging state decreases nonlinearly due to various causes such as increased internal resistance mismatch and imbalance of internal battery heat. Identifying the SOH, which has information on the battery lifespan, can improve battery durability and enhance the reliability of the battery management system by replacing the battery in a timely manner.

The above information may be provided as related art for the purpose of assisting in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

The operation(s) of the electronic device (101) may be processed by one processor (120). Some of the operations of the electronic device (101) may be processed by some of the processors (120) among the plurality of processors (120), and other of the operations of the electronic device (101) may be processed by other some of the processors (120) among the plurality of processors (120). Hereinafter, even when a plurality of processors (120) are implemented, for convenience of explanation, the terms “operation of the electronic device (101)” or “operation of the processor (120)” will be used. According to one embodiment, the memory (130) may include instructions that are set to cause at least one operation. When executed by the processor (120) of the electronic device (101), the instructions may cause the electronic device (101) to perform at least one operation. The electronic device (101) may include one or more memories (130). Hereinafter, “memory (130)” may be one memory (130) or a plurality of memories (130). The instructions may be stored in one memory (130). Some of the instructions may be stored in some of the plurality of memories (130), and other of the instructions may be stored in other of the plurality of memories (130). Hereinafter, even when the memory (130) is implemented in multiple pieces, it will be referred to as “memory (130)” for convenience of explanation. According to one embodiment, a computer readable storage medium storing instructions configured to cause at least one operation may be proposed.

According to one embodiment, referring to FIG. 2, the electronic device (101) may include a battery (210). The battery (210) of FIG. 2 may be the battery (189) of FIG. 1. The battery (210) may include a cell (220) (e.g., a battery cell) and a protector (230). The cell (220) (e.g., a battery cell) may store power. The protector (230) may be a configuration for protecting the cell (220) (e.g., a battery cell). The cell (220) (e.g., a battery cell) may receive power from the power management module (188) through the protector (230). The cell (220) (e.g., a battery cell) may provide power to the power management module (188) through the protector (230). By the power management module (188), charging and discharging of the battery (210) can be performed. In order to identify the state-of-health (SOH) of the battery (210), the electronic device (101) can configure accumulated battery usage environment patterns for each user into a heat map. The heat map (e.g., FIG. 5) can be composed of the temperature of the battery (210), the state-of-charge (SOC) of the battery (210) (e.g., charge amount, charge ratio), and time (e.g., maintenance time). For example, the heat map (e.g., FIG. 5) can have the temperature of the battery (210) as the x-axis, and the SOC of the battery (210) as the y-axis. The heat map can include section(s). The section(s) of the heat map can correspond to the temperature of the battery (210) and the SOC of the battery (210). The heat map can represent the maintenance time(s) of the section(s).

Hereinafter, for convenience of explanation, an SOC of, for example, 60 may mean that the ratio of the remaining capacity of the battery (210) to the total capacity of the battery (210) is 60[%]. However, those skilled in the art will understand that the following examples can also be applied to cases where the unit of SOC is [mAh] rather than [%].

The “use state” may be a general state in which the electronic device (101) (e.g., processor (120)) operates. The “use state” may be a state in which the electronic device (101) is used by a user, or may be a state in which the user does not operate the electronic device (101) but the electronic device (101) performs a general operation. In the use state, the electronic device (101) (e.g., the processor (120)) may consume a general level of power. The general level of power may be power greater than or equal to a reference power. The “standby state” may be a state in which the electronic device (101) (e.g., the processor (120)) is in a low power mode or a power saving mode in order to reduce power consumption. In the standby state, the electronic device (101) (e.g., the processor (120)) may consume power less than a reference power. In FIG. 3, “charging” and “use” may be included in the use state. “Charging” may mean that power is supplied to the battery (210). Charging may be performed in the use state, or charging may be performed in the standby state. However, in FIG. 3, for the convenience of explanation, “charging” is described as charging included in the use state. In FIG. 3, “charging” may mean that the electronic device (101) (e.g., the processor (120)) is in a use state while power is supplied by the battery (210). In FIG. 3, “use” may mean that the electronic device (101) (e.g., the processor (120)) is in a use state while power is not supplied by the battery (210). In FIG. 3, “standby” may mean that the electronic device (101) (e.g., the processor (120)) is in a standby state. Up to the first time point t1 of FIG. 3, the SOC of the battery (210) may increase depending on the “charging.” Up to the first time point t1 of FIG. 3, the temperature of the battery (210) may increase or be maintained depending on the “charging.” From the first time point t1 to the second time point t2 of FIG. 3, the SOC of the battery (210) may decrease depending on the "use". From the first time point t1 to the second time point t2 of FIG. 3, the temperature of the battery (210) may decrease depending on the "use". From the second time point t2 to the fifth time point t5 of FIG. 3, the SOC of the battery (210) may be maintained or decreased depending on the "standby". From the second time point t2 to the fifth time point t5 of FIG. 3, the temperature of the battery (210) may decrease depending on the "standby". After the fifth time point t5 of FIG. 3, the SOC of the battery (210) may decrease depending on the "use". After the fifth time point t5 of FIG. 3, the temperature of the battery (210) may increase or be maintained depending on the "use". In FIG. 3, in the use state (e.g., the period corresponding to "charging" and "use"), data polling may be performed more frequently than in the standby state (e.g., the period corresponding to "standby"). In the standby state, data polling may be performed less frequently than in the use state. As described above, data polling may be performed when the processor (120) requests the fuel gauge (240) to provide data. In the use state, the processor (120) may frequently request the fuel gauge (240) to provide data. In the standby state, the processor (120) may infrequently request the fuel gauge (240) to provide data. For example, in the use state, the interval between the time points of data polling may be less than or equal to a reference interval. For example, in the standby state, the interval between the time points of data polling may be greater than or equal to a reference interval. Data polling in a standby state may be performed when the processor (120) in the standby state temporarily wakes up and requests the fuel gauge (240) to provide data. The wake-up may be a transition from the standby state to the use state. For example, in FIG. 3, from the previous time point to the first time point t1, a “charging” period may be present, from the first time point t1 to the second time point t2, a “use” period may be present, from the second time point t2 to the fifth time point t5, a “standby” period may be present, and after the fifth time point t5, a “use” period may be present. In FIG. 3, the processor (120) may perform data polling at a normal frequency (e.g., frequently) in the use state until the second time point t2. The processor (120) may perform data polling at the second time point t2 and then enter the standby state. The processor (120) (e.g., at least some of the processors (120)) may maintain a standby state from a second time point t2 to a third time point t3, and may request the fuel gauge (240) to provide data at the third time point t3. The third time point t3 may be a time point at which the processor (120) in the standby state temporarily wakes up. The fuel gauge (240) may provide data (e.g., a temperature value and/or an SOC value of the battery (210)) to the processor (120) upon receiving a request for the provision of data at the third time point t3. Thereafter, the processor (120) (e.g., at least some of the processors (120)) may enter the standby state again. Similarly, the processor (120) (e.g., at least some of the processors (120)) may maintain a standby state from a third time point t3 to a fourth time point t4, and may perform data polling at a fourth time point t4 when it temporarily wakes up. Thereafter, the processor (120) (e.g., at least some of the processors (120)) may enter the standby state again. The processor (120) (e.g., at least some of the processors (120)) may maintain the standby state after the fourth time point t4, and may transition to a use state at a fifth time point t5. The processor (120) may perform data polling at a normal frequency from the fifth time point t5. There is no limitation on the interval between the time points of data polling in the use state and the interval between the time points of data polling in the standby state.

The description of FIGS. 2 and 3 can be applied to the embodiments described later. When describing the embodiments described later, parts that overlap with the description of FIGS. 2 and 3 can be omitted. Parts omitted in the description of each drawing or each embodiment can be understood by referring to the description of other drawings or embodiments.

FIG. 6 is a diagram explaining the operation of an electronic device according to one embodiment. FIGS. 4, 5, and 6 can be explained with reference to the previously described embodiments and the embodiments described below.

At least some of the operations of Fig. 4 may be omitted. The order of the operations of Fig. 4 may be changed. Operations other than the operations of Fig. 4 may be performed before, during, or after the operations of Fig. 4 are performed.

Fig. 5 (a) may be an example of a heat map. Fig. 5 (b) may be an example of a heat map retention time. Fig. 6 may be a diagram explaining data polling and retention time.

Referring to FIG. 4, in operation 401, according to one embodiment, the electronic device (101) (e.g., the processor (120)) can check the temperature of the battery (210) and the SOC of the battery (210). The electronic device (101) (e.g., the processor (120)) can check the temperature of the battery (210) and the SOC of the battery (210) through data polling. As described above in FIG. 2 and FIG. 3, the electronic device (101) (e.g., the processor (120)) can check the temperature and SOC of the battery (210) by using the fuel gauge (240). For example, referring to FIG. 5, the electronic device (101) (e.g., processor (120)) can check the first temperature and the first SOC of the battery (210) at a first time point (e.g., p1 of FIG. 5), and check the first temperature and the first SOC of the battery (210) at a second time point (e.g., p5 of FIG. 5).

In operation 403, according to one embodiment, the electronic device (101) (e.g., the processor (120)) may check section(s) of the heat map. Referring to (a) of FIG. 5, the heat map may include a plurality of sections. Each of the plurality of sections of the heat map may correspond to a certain range of the temperature of the battery (210) and a certain range of the SOC of the battery (210). The electronic device (101) (e.g., the processor (120)) may check a first section corresponding to a first temperature and a first SOC at a first time point, a second section corresponding to a second temperature and a second SOC at a second time point, and transit section(s) between the first section and the second section. The transit section(s) may be section(s) in which the temperature of the battery (210) and the SOC of the battery (210) are expected to be included during a specific period. The first section, the transit section, and the second section may be the same or different. If the first section and the second section are the same, there may be no transit section. If the first section and the second section are different, there may or may not be a transit section. The transit section may be one section or a plurality of sections. For example, the electronic device (101) (e.g., the processor (120)) may identify the first section corresponding to the first temperature and the first SOC using a bisectional method. The bisectional method may be a method of dividing the temperature range (or the SOC range) in half, identifying which range the identified temperature (or the identified SOC) is included in, and repeatedly performing this operation to identify the section including the identified temperature (or the identified SOC). There is no limitation on the method by which the electronic device (101) (e.g., the processor (120)) identifies the section corresponding to the identified temperature and the identified SOC. The section(s) of the heat map can be understood as follows. Referring to (a) of FIG. 5, the temperature range of the battery (210) can be divided into sx1 (e.g., -10 degrees Celsius to 0 degrees Celsius), sx2 (e.g., 0 degrees Celsius to 18 degrees Celsius), sx3 (e.g., 18 degrees Celsius to 26 degrees Celsius), sx4 (e.g., 26 degrees Celsius to 32 degrees Celsius), sx5 (e.g., 32 degrees Celsius to 42 degrees Celsius), sx6 (e.g., 42 degrees Celsius to 46 degrees Celsius), sx7 (e.g., 46 degrees Celsius to 50 degrees Celsius), and sx8 (e.g., 50 degrees Celsius or more). For example, referring to (a) of FIG. 5, the ranges of the SOC of the battery (210) may be divided into sy1 (e.g., 0% to 5%), sy2 (e.g., 5% to 60%), sy3 (e.g., 60% to 80%), sy4 (e.g., 80% to 85%), sy5 (e.g., 85% to 90%), sy6 (e.g., 90% to 95%), sy7 (e.g., 95% to 98%), and sy8 (e.g., 98% to 100%). The temperature range and the SOC range of (a) of FIG. 5 are only examples. In FIG. 5, at a first time point (e.g., p1), the first temperature may be included in the fifth range sx5, and the first SOC may be included in the third range sy3. The electronic device (101) (e.g., the processor (120)) can determine that the first temperature and the first SOC at the first time point are included in the first section, which corresponds to the fifth temperature range sx5 and the third SOC range sy3. In FIG. 5, at the second time point (e.g., p5), the second temperature may be included in the third range sx3, and the second SOC may be included in the second range sy2. The electronic device (101) (e.g., the processor (120)) can determine that the second temperature and the second SOC at the second time point are included in the second section, which corresponds to the third temperature range sx3 and the second SOC range sy2. The section including the temperature and SOC of the battery (210) can move from the first section to the second section while time flows from the first point in time (e.g., p1) to the second point in time (e.g., p5). The electronic device (101) (e.g., processor (120)) can identify the transit section(s) between the first section and the second section as the section(s) expected to include the temperature and SOC of the battery (210) between the first point in time (e.g., p1) and the second point in time (e.g., p5). The electronic device (101) (e.g., processor (120)) identifies the first point (e.g., p1) corresponding to the first temperature and the first SOC of the first point in time and the second point (e.g., p5) corresponding to the second temperature and the second SOC of the second point in time in the heat map (e.g., (a) of FIG. 5), and connects the first point and the second point. The section(s) through which the line segment passes can be identified as the transit section(s). For example, in Fig. 5, the transit sections can include a section corresponding to the fifth temperature range sx5 and the second SOC range sy2, and a section corresponding to the fourth temperature range sx4 and the second SOC range sy2.

In operation 405, according to one embodiment, the electronic device (101) (e.g., the processor (120)) may calculate the retention time(s) of the section(s) of the heat map. The retention time (e.g., the duration, the stay time) may be a period during which the temperature and the SOC of the battery (210) are included in a temperature range and a SOC range corresponding to a specific section of the heat map. The retention time may be a time for staying in a specific section of the heat map (or a time for passing through a specific section). For example, referring to FIG. 5 , the electronic device (101) (e.g., the processor (120)) may determine a first retention time (e.g., 5.0000 [minutes] of FIG. 5 (b) corresponding to mt1 of FIG. 5 (a)) of a first section corresponding to a first temperature and a first SOC. The electronic device (101) (e.g., processor (120)) can check the second holding time of the second section corresponding to the second temperature and the second SOC (e.g., 7.5000 [minutes] of FIG. 5 (b) corresponding to mt4 of FIG. 5 (a)). The electronic device (101) (e.g., processor (120)) can check the holding time(s) of the transit section(s) between the first section and the second section (e.g., 6.2500 [minutes] of FIG. 5 (b) corresponding to mt2 of FIG. 5 (a) and 11.2500 [minutes] of FIG. 5 (b) corresponding to mt3 of FIG. 5 (a)). In one embodiment, the electronic device (101) (e.g., the processor (120)) can generate a linear equation using the first temperature, the first SOC, the second temperature, and the second SOC. The electronic device (101) (e.g., the processor (120)) can identify the transit section(s) using the linear equation. The electronic device (101) (e.g., the processor (120)) can identify the maintenance time of at least one section among the sections of the heat map using the heat map of the battery (210) and the linear equation.

According to one embodiment, in operation 405, the configurations of the heatmap for calculating the holding time(s) are described as follows. Referring to FIG. 6, the electronic device (101) (e.g., the processor (120)) can identify a temperature, an SOC, a point (e.g., p) corresponding to the temperature and the SOC in the heatmap, and a time point (e.g., t). For example, the electronic device (101) (e.g., the processor (120)) can perform data polling at time n-1 and perform data polling at time n. The electronic device (101) (e.g., the processor (120)) can identify temperature (n-1), SOC (n-1), and point p (n-1) at time n. The electronic device (101) (e.g., the processor (120)) can identify temperature (n), SOC (n), and point p (n) at time n. The electronic device (101) (e.g., processor (120)) can check the time interval (e.g., dt) between time point n and time point n-1. For example, in FIG. 5, the electronic device (101) (e.g., processor (120)) can check the first temperature and the first SOC at the first time point, check the second temperature and the second SOC at the second time point, and check the time interval between the first time point and the second time point. The electronic device (101) (e.g., processor (120)) can generate a linear equation (e.g., a first-order equation) using the first temperature, the first SOC, the second temperature, and the second SOC. The electronic device (101) (e.g., the processor (120)) can identify a line segment connecting a first point (e.g., p1 of FIG. 5) corresponding to a first temperature and a first SOC and a second point (e.g., p5 of FIG. 5) corresponding to a second temperature and a second SOC by using a linear equation. The electronic device (101) (e.g., the processor (120)) can identify the intersection(s) of the linear equation (e.g., the line segment connecting the first point (e.g., p1 of FIG. 5) and the second point (e.g., p5 of FIG. 5)) and the boundary(s) of the section(s) of the heat map (e.g., the coordinate(s) of the intersection(s)). The heat map can have the temperature of the battery (210) as the x-axis and the SOC of the battery (210) as the y-axis. The boundary line(s) of the interval(s) of the heatmap can include lines perpendicular to the x-axis (e.g., bx1, bx2, bx3, bx4, bx5, bx6, and bx7) and lines perpendicular to the y-axis (e.g., by1, by2, by3, by4, by5, by6, and by7). For example, in FIG. 5, the boundary lines of a first interval (e.g., (sx5, sy3)) that includes a first point (e.g., p1 in FIG. 5) can include bx4, bx5 which are perpendicular to the x-axis and by2, by3 which are perpendicular to the y-axis. For example, in FIG. 5, the boundary lines of a second interval (e.g., (sx3, sy2)) that includes a second point (e.g., p5 in FIG. 5) can include bx2, bx3 which are perpendicular to the x-axis and by1, by2 which are perpendicular to the y-axis. For example, in FIG. 5, the boundary lines of a first transit section (e.g., (sx5, sy2)) among the transit sections may include bx4, bx5 which are perpendicular to the x-axis and by1, by2 which are perpendicular to the y-axis. For example, in FIG. 5, the boundary lines of a second transit section (e.g., (sx4, sy2)) among the transit sections may include bx3, bx4 which are perpendicular to the x-axis and by1, by2 which are perpendicular to the y-axis. In FIG. 5, the intersection point(s) of a linear equation (e.g., a line segment connecting a first point (e.g., p1 in FIG. 5) and a second point (e.g., p5 in FIG. 5)) and the boundary line(s) of the section(s) of the heat map may be p2, p3, and p4. For example, a linear equation (e.g., a line segment connecting a first point (e.g., p1 in FIG. 5) and a second point (e.g., p5 in FIG. 5)) can intersect at by2 and p2, at bx4 and p3, and at bx3 and p4. The coordinate(s) of the intersection point(s) can be the x-coordinate or the y-coordinate of the intersection point(s). An embodiment using the x-coordinate will be described as an example, and this description can also be applied to an embodiment using the y-coordinate. In FIG. 5, the linear equation (e.g., a line segment connecting a first point (e.g., p1 in FIG. 5) and a second point (e.g., p5 in FIG. 5)) and the coordinates of boundary line(s) of the section(s) of the heatmap can be the x-coordinate of p2, the x-coordinate of p3, and the x-coordinate of p4. As a result, in FIG. 5, the electronic device (101) (e.g., the processor (120)) can check the x-coordinate of p1 (e.g., the first temperature), the x-coordinate of p2, the x-coordinate of p3, the x-coordinate of p4, and the x-coordinate of p5 (e.g., the second temperature). The electronic device (101) (e.g., the processor (120)) can sort (e.g., sort in ascending order or descending order) the coordinates of the starting point in the heat map, the coordinates of the intersection point(s) of the linear equation and the section(s), and the coordinates of the ending point. The electronic device (101) (e.g., processor (120)) can calculate the duration(s) of the 405 operation based on the coordinates (e.g., x-coordinate of p1 (e.g., first temperature), x-coordinate of p2, x-coordinate of p3, x-coordinate of p4, and x-coordinate of p5 (e.g., second temperature)) and the time interval between the first time point and the second time point.

At least some of the operations of Fig. 7 may be omitted. The order of the operations of Fig. 7 may be changed. Operations other than the operations of Fig. 7 may be performed before, during, or after performing the operations of Fig. 7.

Fig. 8 is an embodiment in which the first and second sections are the same. Fig. 9 is an embodiment in which the SOC range of the first section and the SOC range of the second section are the same. Fig. 10 is an embodiment in which the temperature range of the first section and the temperature range of the second section are the same.

Referring to FIG. 7, in operation 701, according to one embodiment, the electronic device (101) (e.g., the processor (120)) may check the first temperature and the first SOC of the battery (210) at a first time point (e.g., p1 of FIGS. 8, 9, 10, and 11) by using the fuel gauge (240). As described above with reference to FIGS. 2 and 3, the electronic device (101) (e.g., the processor (120)) may check the temperature and the SOC of the battery (210) by using the fuel gauge (240). In operation 703, according to one embodiment, the electronic device (101) (e.g., the processor (120)) can check the second temperature and the second SOC of the battery (210) at a second time point (e.g., p2 of FIGS. 8, 9, 10, and 11) by using the fuel gauge (240). The electronic device (101) (e.g., the processor (120)) can check the time interval between the second time point of operation 703 and the first time point of operation 701.

In operation 705, according to one embodiment, the electronic device (101) (e.g., the processor (120)) may identify section(s) of the heat map. As described above with reference to FIG. 4, the electronic device (101) (e.g., the processor (120)) may identify a first section including a first point corresponding to a first temperature and a first SOC, identify a second section including a second point corresponding to a second temperature and a second SOC, and identify transit section(s) between the first section and the second section. In the embodiment of FIG. 8 described below, since the first section and the second section are the same, there may be no transit section.

In operation 707, according to one embodiment, the electronic device (101) (e.g., the processor (120)) may generate a linear equation (e.g., a first-order equation having temperature and SOC as variables) using the first temperature and the first SOC of operation 701 and the second temperature and the second SOC of operation 703. The electronic device (101) (e.g., the processor (120)) may identify a line segment connecting a first point (e.g., p1 of FIGS. 8, 9, 10, and 11) corresponding to the first temperature and the first SOC and a second point (e.g., p2 of FIGS. 8, 9, 10, and 11) corresponding to the second temperature and the second SOC, using the linear equation. In operation 709, according to one embodiment, the electronic device (101) (e.g., the processor (120)) can identify the intersection(s) of a linear equation (e.g., a line segment connecting a first point (e.g., p1 of FIGS. 8, 9, 10, and 11) and a second point (e.g., p2 of FIGS. 8, 9, 10, and 11)) and boundary(s) of section(s) of the heatmap (e.g., coordinate(s) of the intersection(s)). The electronic device (101) (e.g., the processor (120)) can sort (e.g., sort in ascending order or descending order) the coordinate(s) of the starting point, the coordinate(s) of the intersection(s) of the linear equation and the section(s), and the coordinate(s) of the ending point in the heatmap. In operation 711, according to one embodiment, the electronic device (101) (e.g., the processor (120)) may calculate the retention time(s) of the section(s) of the heat map based on the coordinates of the intersection(s) and the time interval between the first time point and the second time point. The operations of FIG. 7 may be described with reference to FIGS. 8, 9, 10, and 11. In FIGS. 8, 9, 10, and 11, the temperature interval and the SOC interval are both illustrated as 1, but this is an exemplary embodiment for the convenience of description. In FIGS. 8, 9, 10, and 11, the units of temperature and SOC are omitted and described.

With reference to FIG. 8, the operations of FIG. 7 can be described. In (a) of FIG. 8, the electronic device (101) (e.g., the processor (120)) can check the first temperature and the first SOC at the first time point, and check the second temperature and the second SOC at the second time point. The electronic device (101) (e.g., the processor (120)) can check the time interval between the first time point and the second time point. Between the first time point and the second time point, the processor (120) can be in a standby state. The electronic device (101) (e.g., the processor (120)) can check that the first point (e.g., p1) corresponding to the first temperature and the first SOC is included in the first section, and that the second point (e.g., p2) corresponding to the second temperature and the second SOC is included in the same first section. In this case, the electronic device (101) (e.g., processor (120)) can determine that the temperature and SOC of the battery (210) do not pass through other sections, but remain in the first section. Therefore, in FIG. 8, the electronic device (101) (e.g., processor (120)) can calculate the maintenance time of the first section as the time interval between the first time point and the second time point. For example, in FIG. 8 (b), if the time interval between the first time point and the second time point is 30 minutes, the maintenance time of the first section (e.g., the temperature range of 2 to 3 and the SOC range of 5 to 6) can be calculated as 30 minutes.

Referring to FIG. 9, the operations of FIG. 7 can be described. In (a) of FIG. 9, the electronic device (101) (e.g., processor (120)) can check the first temperature and the first SOC at the first time point, and check the second temperature and the second SOC at the second time point. The electronic device (101) (e.g., processor (120)) can check the time interval between the first time point and the second time point. Between the first time point and the second time point, the processor (120) can be in a standby state. An electronic device (101) (e.g., processor (120)) can confirm that a first point (e.g., p1) corresponding to a first temperature and a first SOC is included in a first section (e.g., a temperature range of 4 to 5 and a SOC range of 5 to 6), and a second point (e.g., p2) corresponding to a second temperature and a second SOC is included in a second section (e.g., a temperature range of 1 to 2 and a SOC range of 5 to 6). The SOC ranges of the first section and the second section may be the same. The temperature ranges of the first section and the second section may be different. The electronic device (101) (e.g., processor (120)) can confirm a transit section between the first section and the second section. The electronic device (101) (e.g., processor (120)) can generate a linear equation using the first point in time, the first SOC, the second point in time, and the second SOC. For example, the electronic device (101) (e.g., processor (120)) can identify a transit section between the first section and the second section using the linear equation (e.g., a line segment connecting the first point (e.g., p1) and the second point (e.g., p2)). In FIG. 9 (a), transit sections including the first transit section (e.g., a temperature range of 3 to 4 and an SOC range of 5 to 6) and the second transit section (e.g., a temperature range of 2 to 3 and an SOC range of 5 to 6) can be identified. The electronic device (101) (e.g., the processor (120)) can identify coordinates of intersections of linear equations (e.g., a line segment connecting a first point (e.g., p1) and a second point (e.g., p2)) and boundaries of sections of a heat map (e.g., a first section, a first transit section, a second transit section, and a second section) (e.g., coordinates of the x-axis corresponding to temperatures). The electronic device (101) (e.g., the processor (120)) can sort (e.g., sort in ascending order or descending order) the coordinates of a starting point, the coordinates of the intersections of the linear equation and the sections (s), and the coordinates of the ending point in the heat map. For example, the electronic device (101) (e.g., the processor (120)) can sort the first temperature of the first point, the temperatures of the intersections, and the second temperature of the second point. For example, in (b) of FIG. 9, the first temperature, the coordinates of the intersections, and the second temperature may be, in order, x(n) = 4.8, 4.0, 3.0, 2.0, and 1.5. The electronic device (101) (e.g., the processor (120)) may calculate the holding times corresponding to the first section, the transit sections, and the second section, respectively, based on the first temperature, the coordinates of the intersections, and the second temperature. For example, the electronic device (101) (e.g., the processor (120)) may calculate the holding times using the equation of (c) of FIG. 9. In (c) of FIG. 9, X _SP may be the first temperature which is a start point of the temperature. X _EP may be the second temperature which is an end point of the temperature. T _total may be a time interval between the first point in time and the second point in time. T _SECTION (n) may be a holding time of the nth section. X(n), and X(n+1) may be one of the first temperature, coordinates of the intersections, and the second temperature. The holding time of the first section (e.g., 7.2727 [minutes]) may be determined based on the first temperature, 4.8, and the x-coordinate of the first intersection, 4.0. The holding time of the first transit section (e.g., 9.0909 [minutes]) may be determined based on the x-coordinate of the first intersection, 4.0, and the x-coordinate of the second intersection, 3.0. The holding time of the second transit section (e.g., 9.0909 [minutes]) may be determined based on the x-coordinate of the second intersection, 3.0, and the x-coordinate of the third intersection, 2.0. The holding time of the second section (e.g., 4.5455 [minutes]) can be determined based on the x-coordinate of the third intersection point, 2.0, and the second temperature, 1.5.

Referring to FIG. 10, the operations of FIG. 7 can be described. In (a) of FIG. 10, the electronic device (101) (e.g., processor (120)) can check the first temperature and the first SOC at the first time point, and check the second temperature and the second SOC at the second time point. The electronic device (101) (e.g., processor (120)) can check the time interval between the first time point and the second time point. Between the first time point and the second time point, the processor (120) can be in a standby state. An electronic device (101) (e.g., processor (120)) can confirm that a first point (e.g., p1) corresponding to a first temperature and a first SOC is included in a first section (e.g., a temperature range of 4 to 5 and a SOC range of 5 to 6), and a second point (e.g., p2) corresponding to a second temperature and a second SOC is included in a second section (e.g., a temperature range of 4 to 5 and a SOC range of 2 to 3). The temperature ranges of the first section and the second section may be the same. The SOC ranges of the first section and the second section may be different. The electronic device (101) (e.g., processor (120)) can confirm a transit section between the first section and the second section. The electronic device (101) (e.g., processor (120)) can generate a linear equation using the first point in time, the first SOC, the second point in time, and the second SOC. For example, the electronic device (101) (e.g., processor (120)) can identify a transit section between the first section and the second section using the linear equation (e.g., a line segment connecting the first point (e.g., p1) and the second point (e.g., p2)). In FIG. 10 (a), transit sections including the first transit section (e.g., a temperature range of 4 to 5 and an SOC range of 4 to 5) and the second transit section (e.g., a temperature range of 4 to 5 and an SOC range of 3 to 4) can be identified. The electronic device (101) (e.g., the processor (120)) can check the coordinates (e.g., the coordinates of the y-axis corresponding to the SOC) of the intersections of the linear equation (e.g., the line segment connecting the first point (e.g., p1) and the second point (e.g., p2)) and the boundaries of the sections (e.g., the first section, the first transit section, the second transit section, and the second section) of the heat map. The electronic device (101) (e.g., the processor (120)) can sort (e.g., sort in ascending order or descending order) the coordinates of the starting point, the coordinates of the intersection(s) of the linear equation and the section(s), and the coordinates of the ending point in the heat map. For example, the electronic device (101) (e.g., the processor (120)) can sort the first SOC of the first point, the SOCs of the intersections, and the second SOC of the second point. For example, in (b) of FIG. 10, the first SOC, the coordinates of the intersections, and the second SOC may be y(n) = 5.8, 5.0, 4.0, 3.0, and 2.5, in that order. The electronic device (101) (e.g., the processor (120)) may calculate the holding times corresponding to the first section, the transit sections, and the second section, respectively, based on the first SOC, the coordinates of the intersections, and the second SOC. For example, the electronic device (101) (e.g., the processor (120)) may calculate the holding times using the equation of (c) of FIG. 10. In (c) of FIG. 10, Y _SP may be the first SOC, which is a starting point of the SOC. Y _EP may be the second SOC, which is an end point of the temperature. T _total may be a time interval between the first point in time and the second point in time. T _SECTION (n) may be a holding time of the nth section. Y(n), and Y(n+1) may be one of the first SOC, coordinates of the intersections, and the second SOC. The holding time of the first section (e.g., 7.2727 [minutes]) may be determined based on the first SOC, 5.8, and the x-coordinate of the first intersection, 5.0. The holding time of the first transit section (e.g., 9.0909 [minutes]) may be determined based on the y-coordinate of the first intersection, 5.0, and the y-coordinate of the second intersection, 4.0. The holding time of the second transit section (e.g., 9.0909 [minutes]) may be determined based on the y-coordinate of the second intersection, 4.0, and the y-coordinate of the third intersection, 3.0. The holding time of the second segment (e.g., 4.5455 [minutes]) can be determined based on the y-coordinate of the third intersection point, 3.0, and the second SOC, 2.5.

Referring to FIG. 11, the operations of FIG. 7 can be described. In (a) of FIG. 11, the electronic device (101) (e.g., processor (120)) can check the first temperature and the first SOC at the first time point, and check the second temperature and the second SOC at the second time point. The electronic device (101) (e.g., processor (120)) can check the time interval between the first time point and the second time point. Between the first time point and the second time point, the processor (120) can be in a standby state. An electronic device (101) (e.g., processor (120)) can confirm that a first point (e.g., p1) corresponding to a first temperature and a first SOC is included in a first section (e.g., a temperature range of 5 to 6 and a SOC range of 5 to 6), and can confirm that a second point (e.g., p2) corresponding to a second temperature and a second SOC is included in a second section (e.g., a temperature range of 1 to 2 and a SOC range of 3 to 4). The temperature ranges and SOC ranges of the first section and the second section may be different. The electronic device (101) (e.g., processor (120)) can confirm a transit section between the first section and the second section. The electronic device (101) (e.g., processor (120)) can generate a linear equation using the first point in time, the first SOC, the second point in time, and the second SOC. For example, the electronic device (101) (e.g., the processor (120)) can identify a transit section between the first section and the second section by using a linear equation (e.g., a line segment connecting a first point (e.g., p1) and a second point (e.g., p2)). In (a) of FIG. 11, transit sections including a first transit section (e.g., a temperature range of 4 to 5 and a SOC range of 5 to 6), a second transit section (e.g., a temperature range of 4 to 5 and a SOC range of 4 to 5), a third transit section (e.g., a temperature range of 3 to 4 and a SOC range of 4 to 5), a fourth transit section (e.g., a temperature range of 2 to 3 and a SOC range of 4 to 5), and a fifth transit section (e.g., a temperature range of 2 to 3 and a SOC range of 3 to 4) can be identified. The electronic device (101) (e.g., the processor (120)) can check the coordinates (e.g., the coordinates of the x-axis corresponding to the temperature) of the intersections of the linear equation (e.g., the line segment connecting the first point (e.g., p1) and the second point (e.g., p2)) and the boundaries of the sections of the heat map (e.g., the first section, the first transit section, the second transit section, the third transit section, the fourth transit section, the fifth transit section, and the second section). The electronic device (101) (e.g., the processor (120)) can sort (e.g., sort in ascending order or descending order) the coordinates of the starting point, the coordinates of the intersection(s) of the linear equation and the section(s), and the coordinates of the ending point in the heat map. The coordinates of the y-axis corresponding to the SOC may be used, but the use of the coordinates of the x-axis corresponding to the temperature will be described herein. For example, the electronic device (101) (e.g., the processor (120)) can align the first temperature of the first point, the temperatures of the intersections, and the second temperature of the second point. For example, in (b) of FIG. 11, the first temperature, the coordinates of the intersections, and the second temperature may be, in order, x(n) = 5.2, 5.0, 4.7, 4.0, 3.0, 2.2, 2.0, 1.7. The electronic device (101) (e.g., the processor (120)) can calculate the holding times corresponding to the first section, the transit sections, and the second section, respectively, based on the first temperature, the coordinates of the intersections, and the second temperature. For example, the electronic device (101) (e.g., the processor (120)) can calculate the holding times using the equation of (c) of FIG. 11. The formula of (c) of Fig. 11 may be the same as the formula of (c) of Fig. 9. The holding time of the first section (e.g., 1.7143 [minutes]) may be determined based on the first temperature, 5.2, and the x-coordinate of the first intersection, 5.0. The holding time of the first transit section (e.g., 2.5714 [minutes]) may be determined based on the x-coordinate of the first intersection, 5.0, and the x-coordinate of the second intersection, 4.7. The holding time of the second transit section (e.g., 6.0000 [minutes]) may be determined based on the x-coordinate of the second intersection, 4.7, and the x-coordinate of the third intersection, 4.0. The holding time of the third transit section (e.g., 8.5714 [minutes]) can be determined based on the x-coordinate of the third intersection, 4.0, and the x-coordinate of the fourth intersection, 3.0. The holding time of the fourth transit section (e.g., 6.8571 [minutes]) can be determined based on the x-coordinate of the fourth intersection, 3.0, and the x-coordinate of the fifth intersection, 2.2. The holding time of the fifth transit section (e.g., 1.7143 [minutes]) can be determined based on the x-coordinate of the fifth intersection, 2.2, and the x-coordinate of the sixth intersection, 2.0. The holding time of the second section (e.g., 2.5714 [minutes]) can be determined based on the x-coordinate of the sixth intersection, 2.0, and the second temperature, 1.7.
