4) Other terms

In the embodiments of the present application, words such as "first" and "second" are used to distinguish the same or similar items with basically the same function and effect. For example, the first chip and the second chip are only used to distinguish different chips, and their sequence is not limited. Those skilled in the art can understand that words such as "first" and "second" do not limit the quantity and execution order, and words such as "first" and "second" do not necessarily limit the difference.

It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used as examples, illustrations or descriptions. Any embodiment or design described herein as "exemplary" or "for example" is not to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. "And/or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and/or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone, where A, B can be singular or plural.

More and more users are accustomed to charging the electronic equipment while using the electronic equipment (such as a mobile phone, etc.).

Exemplarily, the user uses the mobile phone while charging the mobile phone, for example, uses the mobile phone to watch videos, play games, make calls, or read novels.

In some implementations, the charging process of the electronic device includes three stages: constant current pre-charging, high-current constant-current charging, and constant-voltage charging.

Exemplarily, the battery of the mobile phone is generally a lithium battery, and when the battery voltage of the mobile phone is lower than 3.0V, the charger will precharge the lithium battery with a current of 100 milliamperes (milliampere, mA).

When the lithium battery voltage is higher than 3.0V, it enters the second phase, the high current constant current charging phase. Since the lithium battery has been pre-charged in the first stage, its state has been relatively stable, so in the second stage, the charging current can be increased appropriately. According to different batteries, the current can vary from 0.1 coulomb (coulomb, C ) to several C, where C refers to the battery capacity, such as a 2600 milliampere hour (mAh) lithium battery, and 0.1C refers to a current of 260mA.

When it is detected that the lithium battery voltage is equal to 4.2V, the charger will enter the constant voltage charging mode. At this stage, the charging voltage is constant at 4.2V, and the charging current is getting smaller and smaller. When the charging current is less than 100mA, it is judged that the battery is fully charged and the charging circuit is cut off.

However, when charging based on the existing charging process, since the same electronic device will be charged with the same charging current under different load scenarios, when the power of the electronic device is low and the electronic device is in a light-load scenario, the charging current It may make the power increase rate of the electronic device not fast enough. In the heavy-load scenario of the electronic device, the charging current may cause the electronic device to heat up rapidly, affecting user experience. Therefore, when charging based on the existing charging process, it is easy to cause a longer charging time or a faster temperature rise of the electronic device.

Exemplarily, the charging current is Q, for example. When the user keeps the phone on while charging the phone, or performs some operations that put the phone in a light-load scene, since the heat generated by the processor in the phone is low in the light-load scene, when the phone is under light load In this scenario, when the current Q is used for constant current charging, the temperature increase of the mobile phone is small, and the temperature threshold of the mobile phone may not be reached. Therefore, the charging current of the mobile phone can be greater than Q at this time. That is to say, within the allowable range of the temperature rise of the mobile phone, when the mobile phone is charged with a constant current Q at a light load, the battery power growth rate of the mobile phone is not fast enough, which makes the charging time of the mobile phone longer.

When the user uses the mobile phone to watch videos, play games or perform other operations that put the mobile phone in a heavy load scene while charging the mobile phone, the heat generated by the high-speed operation of the processor in the mobile phone and the heat generated when the current Q is used for constant current charging will be The temperature of the mobile phone rises rapidly, which affects the user experience.

In view of this, an embodiment of the present application provides a charging method, which dynamically adjusts the charging current of the electronic device according to the temperature and power of the electronic device in a heavy-load scenario, for example, when the temperature of the electronic device is high or the power is high , the electronic device is charged with a lower charging current. When the power of the electronic device is low, the charging current of the electronic device is determined according to the temperature of the electronic device. When the temperature of the electronic device is high, the charging current is small. When it is low, the charging current is large. In this way, when the temperature of the electronic device is low and the power is low, a larger current is used for charging, which can quickly increase the power of the electronic device and effectively reduce the power anxiety when the power is low. As the charging of the electronic device continues, the temperature of the electronic device As the temperature rises, the charging current will be reduced, and the heat generated by the electronic equipment will be reduced, thereby effectively delaying the temperature rise of the electronic equipment.

The technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the above technical problems will be described in detail below with reference to the accompanying drawings. The following specific embodiments may be implemented independently, or may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 4 is a schematic flowchart of a charging method according to an embodiment of the present application. As shown in Figure 4, methods can include:

S401: The electronic device starts charging.

In a possible implementation, starting charging of the electronic device may be connecting the electronic device to a charging power source. Wherein, the electronic device may be connected to the charging power source in a wired or wireless manner, which is not limited in this embodiment of the present application.

Exemplarily, when the electronic device is charged using a wired charging cable, the electronic device can be connected to a power source through the wired charging cable, so as to start charging.

Exemplarily, when the electronic device is charged using the wireless charging base, the electronic device can be connected to a power source through the wireless charging coil, so as to start charging.

S402: Obtain power consumption of the electronic device during charging.

Wherein, the power consumption can be understood as the current value of power consumption of the electronic equipment, for example, the current value received by the electronic equipment from the charger is 1000mA, and the current value received by the battery of the electronic equipment is 200mA, then the power consumption of the electronic equipment is about 800mA (from The difference between the current value received by the charger and the current value received by the battery of the electronic device).

In a possible implementation, after the electronic device starts charging, the electronic device can periodically collect the current value received from the charger and the current value received by the battery of the electronic device, and based on the current value collected from the charger and the current value received by the battery of the electronic device The current value is calculated to obtain the power consumption of the electronic device during charging.

Exemplarily, after the electronic device starts charging, a current value received from the charger and a current value received by the battery of the electronic device are collected every 10s, the difference between the two current values is calculated, and 10 current values received from the charger are collected. After the current value and the current value received by the battery of 10 electronic devices, 10 difference values are obtained, and the average value of the 10 difference values is calculated to obtain the power consumption. After every 10s, replace the first current value collected from the charger with the current value received by the battery of the first electronic device, and then recalculate the power consumption. It is equivalent to having a smooth sliding window and calculating the power consumption in each window.

S403: When the power consumption is greater than or equal to the first threshold, determine whether the temperature of the electronic device is greater than the first temperature threshold.

Wherein, the first threshold may be the dividing line between the heavy load scene and the medium load scene of the electronic device, for example, the first threshold may be 800mA, and when the power consumption is greater than or equal to 800mA, the electronic device is in the heavy load scene. It can be understood that the power consumption greater than or equal to the first threshold in the embodiment of the present application may also mean that the power consumption is greater than the first threshold, and the present application does not specifically limit whether the first threshold belongs to a heavy-load scenario or a medium-load scenario.

Wherein, the temperature of the electronic device may include a battery temperature or a casing temperature of the electronic device, which may reflect the overall temperature of the electronic device. The first temperature threshold may be a preset value for an electronic device at a relatively low temperature in a heavy-load scenario, for example, the first temperature threshold may be a casing temperature of a mobile phone of 30 degrees Celsius (° C.).

In a possible implementation, the electronic device will monitor its own bright screen status, temperature, power, etc. in real time during the charging process. When the power consumption is greater than or equal to the first threshold, it is determined whether the monitored temperature of the electronic device is greater than the first temperature threshold.

It is understandable that the heat generated by electronic equipment is greater and the temperature rises faster in heavy-load scenarios. Therefore, in order to prevent accidents such as shutdown or damage of electronic equipment due to overheating of electronic equipment, The temperature of the device is the first judgment priority, that is to say, when determining the charging current of the electronic device, it must be satisfied that the temperature of the electronic device is within the allowable range of intelligent charging.

S404: When the temperature of the electronic device is less than or equal to the first temperature threshold, determine whether the power of the electronic device is greater than the first power threshold.

Wherein, the first power threshold may be a preset value used to determine the charging current of the electronic device in a heavy load scenario, and the charging current of the electronic device refers to the current at the battery terminal, or refers to the current received by the battery of the electronic device.

Exemplarily, when the temperature of the electronic device is less than or equal to the first temperature threshold, the power of the electronic device is judged; when the power of the electronic device is greater than the first power threshold, considering the safety of charging, when the power of the electronic device is greater than When the first power threshold is reached, a smaller current is used for charging. When the power of the electronic device is less than the first power threshold, the charging current of the electronic device is determined according to the temperature of the electronic device.

S405: When the power of the electronic device is greater than the first power threshold, the electronic device is charged with the lowest charging current value.

Wherein, the lowest charging current value can be understood as a normal charging current value.

Exemplarily, when the power of the electronic device is greater than the first power threshold, the electronic device is charged with a normal charging current value, and it can be understood that the normal charging current value at this time is relatively small.

S406: When the power of the electronic device is less than or equal to the first power threshold, the electronic device is charged with the first current value; and, as the charging of the electronic device continues, when the temperature of the electronic device is greater than the first temperature threshold and less than or equal to the second temperature threshold, the electronic device is charged with a second current value, and the second current value is greater than the lowest charging current value and less than the first current value; when the temperature of the electronic device is greater than the second temperature threshold, the electronic device uses The lowest charging current value for charging.

Wherein, the second temperature threshold may be a temperature value at which the user can clearly perceive the heating of the electronic device in a heavy-load scenario, for example, it may be 38°C. When the temperature of the electronic device is greater than the second temperature threshold, the user may clearly perceive the electronic device The temperature of the electronic device has risen, therefore, the electronic device is charged with the lowest charging current value to slow down the temperature rise of the electronic device.

The first current value, the second current value, and the lowest charging current value in the embodiments of the present application may all be currents at the battery terminal (also referred to as charging current or battery charging current).

Wherein, the first current value may be relatively high, which satisfies the electric power demand of the heavy load scene. For example, a user plays a game with a mobile phone, so that the power of the mobile phone is already lower than the safety line of the mobile phone, which can be 20% or 30%, for example. At this time, the user continues to play the game while charging, and the mobile phone will use the first current. The value is charged to increase the power of the mobile phone above the safety line quickly, prevent the power of the mobile phone from losing power, and reduce the power anxiety of the mobile phone.

Exemplarily, the user begins to charge the mobile phone while watching a long video. When the temperature of the mobile phone's shell is lower than the first temperature threshold and the power of the mobile phone is lower than the first power threshold, the mobile phone is charged with the first current value. As the charging of the mobile phone continues, the battery power and shell temperature of the mobile phone will increase accordingly. When the shell temperature of the mobile phone is greater than the first temperature threshold and less than or equal to the second temperature threshold, the mobile phone will be charged with the second current value. The second current value is greater than the lowest charging current value and smaller than the first current value, and when the temperature of the casing of the mobile phone is greater than the second temperature threshold, the electronic device is charged with the lowest charging current value.

Exemplarily, FIG. 5 shows a schematic diagram of an overloaded scene curve provided by an embodiment of the present application. As shown in Figure 5, the heavy-duty scene curve includes the charging current curve of the intelligent charging control mode, the pre-control charging current curve, the actual case temperature curve and the optimized case temperature curve of the electronic device under the heavy-load scene. . As shown in Figure 5, when the user can perceive the heating of the electronic device, for example, when the case temperature is about 37°C, for the actual case temperature curve, the case temperature reaches about 37°C when the charging time is about 4 minutes, while In the optimized case temperature curve, the case temperature only reaches about 37°C when the charging time is about 14 minutes, which obviously delays the temperature rise of the electronic device. When the electronic equipment reaches a strictly controlled temperature, for example, when the shell temperature is around 43°C, for the actual shell temperature curve, the shell temperature reaches around 43°C when the charging time is about 20 minutes, and the optimized shell temperature In the curve, the temperature of the casing only reaches about 43°C when the charging time is about 26 minutes, which also delays the temperature rise of the electronic equipment. That is to say, in heavy load scenarios, the temperature of the optimized case will rise later, and the user will perceive the heating of the electronic device later, which can effectively improve the user experience.

To sum up, in the embodiment of the present application, the electronic device starts charging; the power consumption of the electronic device during charging is obtained; when the power consumption is greater than or equal to the first threshold, it is judged whether the temperature of the electronic device is greater than the first temperature threshold; when the electronic device When the temperature of the electronic device is less than or equal to the first temperature threshold, it is judged whether the power of the electronic device is greater than the first power threshold; when the power of the electronic device is greater than the first power threshold, the electronic device is charged with the lowest charging current value; when the power of the electronic device When it is less than or equal to the first power threshold, the electronic device is charged with the first current value; and, as the charging of the electronic device continues, when the temperature of the electronic device is greater than the first temperature threshold and less than or equal to the second temperature threshold , the electronic device is charged with a second current value, and the second current value is greater than the lowest charging current value and smaller than the first current value; when the temperature of the electronic device is greater than the second temperature threshold, the electronic device is charged with the lowest charging current value. In this way, when the temperature of the electronic device is low and the power is low, a larger current is used for charging, which can quickly increase the power of the electronic device, effectively reduce the power anxiety when the power is low, and reduce the charging current when the temperature of the electronic device rises. Reduce the heat generated by electronic equipment in heavy load scenarios, thereby effectively delaying the temperature rise of electronic equipment.

On the basis of the above embodiments, in order to more clearly describe the technical solutions provided by the embodiments of the present application, for example, please refer to Figure 6, which shows a schematic flow chart of a charging method provided by the embodiments of the present application, including :

S601: Charging starts.

This step is similar or identical to the above step S401, and will not be repeated here.

S602: Record the status of the mobile phone when charging is started, and the status may include parameters such as battery temperature, power quantity, charging start time, casing temperature and the like.

Wherein, the power can be represented by a percentage, for example, the power of the mobile phone is 20%.

S603: Obtain the power consumption of the electronic device.

This step is similar or identical to the above step S402, and will not be repeated here.

Optionally, step S603 may include:

Obtain the third current value received by the electronic device from the charger at N time points, and the fourth current value received by the battery of the electronic device, and obtain N pairs of third current values and fourth current values associated in pairs, where N is a natural number ; Obtain power consumption according to N pairs of the third current value and the fourth current value.

In a possible implementation, after the electronic device starts charging, the current value collector in the electronic device starts to collect the third current value received by the electronic device from the charger and the fourth current value received by the battery of the electronic device at N time points, N pairs of associated third current values and fourth current values are obtained, and the collected N pairs of third current values and fourth current values are calculated to obtain power consumption.

Exemplarily, the current value collector of the electronic device may collect periodically, for example, collect a pair of the third current value and the fourth current value every 10 seconds, and obtain 10 pairs of the third current value and the fourth current value after 100 seconds.

In the embodiment of the present application, N pairs of pairwise associated third current values and fourth current values are obtained by collecting the third current value received by the electronic device from the charger and the fourth current value received by the battery of the electronic device For the current value, the power consumption is obtained according to the obtained N pairs of the third current value and the fourth current value associated in pairs, so that the scene of the load of the electronic device can be identified subsequently according to the obtained power consumption.

Optionally, the power consumption is obtained according to N pairs of the third current value and the fourth current value, including:

Calculate the difference between any pair of the third current value and the fourth current value in the N pairs of the third current value and the fourth current value, respectively, to obtain N differences; calculate the power consumption according to the preset algorithm for the N pairs of differences, The preset algorithm includes any one of the following: average algorithm, filter valid data first and then average algorithm, and median algorithm.

Exemplarily, a difference operation is performed on each pair of N pairs of the third current value and the fourth current value, where N is 5 for example, then 5 differences are obtained, and 5 differences For example, it can be 809mA, 800mA, 802mA, 812mA, 805mA, and the average value of 5 differences is calculated to obtain a power consumption of 805.6mA; or, remove the lowest value of 800mA and the highest value of 812mA among the 5 differences, and then calculate the average of the remaining values The value gives a power consumption of 805.3mA; or, rearrange the five differences: 800mA, 802mA, 805mA, 809mA, 812mA, and take the median to get a power consumption of 805mA. It is understood that power consumption may be an estimate. The present application does not specifically limit the calculation method for obtaining the power consumption.

In the embodiment of the present application, the power consumption is obtained through simple calculation of N pairs of the third current value and the fourth current value, so that the scene of the load of the electronic device can be identified later based on the obtained power consumption.

S604: When the power consumption is greater than or equal to the first threshold, determine whether the temperature of the electronic device is greater than the first temperature threshold.

This step is similar or the same as the above step S403, and will not be repeated here.

Optionally, before step S604, it also includes:

Determine whether the electronic device is in the bright screen state; when the electronic device is not in the bright screen state, the electronic device is charged with the lowest charging current value; when the power consumption is greater than or equal to the first threshold, determine whether the temperature of the electronic device is greater than the first temperature The threshold includes: when the electronic device is in a bright screen state and the power consumption is greater than or equal to the first threshold, judging whether the temperature of the electronic device is greater than the first temperature threshold.

In a possible implementation, before judging the power consumption, it is judged whether the electronic device is in the bright screen state. When the electronic device is in the off-screen state, the electronic device is charged with the lowest charging current value, or the electronic device enters the normal charging mode. When the electronic device is in the bright screen state, the power consumption, temperature, and electric power of the electronic device are judged, so as to determine the charging current of the electronic device. The specific determination method can refer to the content of the above-mentioned embodiments, and will not be repeated here.

In the embodiment of the present application, judging whether the electronic device is in the bright screen state before judging the power consumption is helpful for subsequently determining the charging current under different load scenarios based on the bright screen state.

S605: When the temperature of the electronic device is less than or equal to the first temperature threshold, determine whether the power of the electronic device is greater than the first power threshold.

This step is similar or identical to the above step S404, and will not be repeated here.

S606: When the power of the electronic device is greater than the first power threshold, the electronic device is charged with the lowest charging current value.

This step is similar or the same as the above step S405, and will not be repeated here.

S607: When the power of the electronic device is less than or equal to the first power threshold, the electronic device is charged with the first current value; and, as the charging of the electronic device continues, when the temperature of the electronic device is greater than the first temperature threshold and less than or equal to the second temperature threshold, the electronic device is charged with a second current value, and the second current value is greater than the lowest charging current value and less than the first current value; when the temperature of the electronic device is greater than the second temperature threshold, the electronic device uses The lowest charging current value for charging.

This step is similar or identical to the above step S406, and will not be repeated here.
