The charging circuit (210) may charge the battery (189) using power supplied from an external power source for the electronic device (101). According to one embodiment, the charging circuit (210) may select a charging method (e.g., normal charging or rapid charging) based on at least some of the type of the external power source (e.g., power adapter, USB, or wireless charging), the amount of power that can be supplied from the external power source (e.g., about 20 watts or more), or the properties of the battery (189), and may charge the battery (189) using the selected charging method. The external power source may be connected to the electronic device (101) by wire, for example, via a connection terminal (178), or wirelessly via an antenna module (197).

The power regulator (220) can generate a plurality of powers having different voltages or different current levels by adjusting the voltage level or current level of the power supplied from, for example, an external power source or a battery (189). The power regulator (220) can adjust the power of the external power source or the battery (189) to a voltage or current level suitable for each of the components included in the electronic device (101). According to one embodiment, the power regulator (220) can be implemented in the form of an LDO (low drop out) regulator or a switching regulator. The power gauge (230) can measure usage status information for the battery (189) (e.g., capacity, number of charge/discharge cycles, voltage, or temperature of the battery (189).

The power management module (188) can determine charging state information (e.g., lifespan, overvoltage, undervoltage, overcurrent, overcharge, overdischarge, overheat, short circuit, or swelling) related to charging of the battery (189) based at least in part on the measured usage state information, for example, using the charging circuit (210), the voltage regulator (220), or the power gauge (230). The power management module (188) can determine whether the battery (189) is normal or abnormal based at least in part on the determined charging state information. If the state of the battery (189) is determined to be abnormal, the power management module (188) can adjust charging of the battery (189) (e.g., reducing the charging current or voltage, or stopping charging). According to one embodiment, at least some of the functions of the power management module (188) can be performed by an external control device (e.g., the processor (120)).

The battery (189) may, according to one embodiment, include a battery protection circuit module (PCM) (240).

According to one embodiment, the corresponding sensor (e.g., a temperature sensor) among the sensor modules (176) may be included as a part of the battery protection circuit (140) or may be placed near the battery (189) as a separate device.

A power supply device may include a direct charging circuit and a switching charging circuit as components for supplying power (in other words, electrical energy) to a power receiving device. The switching charging circuit (e.g., a buck boost converter) may convert a current value and/or a voltage value of input power and output it. For example, the switching charging circuit may adjust a ratio (voltage conversion ratio) of the voltage value of the output power to the voltage value of the input power and output it. The direct charging circuit may convert the voltage value of the input power at a fixed voltage conversion ratio and output it. Although it is difficult to adjust the output voltage because the voltage conversion ratio is fixed, the direct charging circuit may be suitable for fast charging of a battery because it can supply relatively high power. According to an embodiment of the present disclosure, the direct charging circuit and the switching charging circuit may be used as a first power conversion circuit and a second power conversion circuit, respectively, for supporting power supply from the power supply device to the power receiving device.

The first power conversion circuit (313) may be configured to convert a voltage value of power input from one of the two terminals (313a, 313b) at a fixed voltage conversion ratio (a ratio of a voltage value of power output to a voltage value of power input) and output the converted voltage to the other of the two terminals (313a, 313b). The first power conversion circuit (313) may include a circuit (e.g., a switched capacitor voltage divider (SCVD)) configured such that the ratio of output power to input power is ‘1’. For example, the first power conversion circuit (313) can convert the voltage value (e.g., 4.5 V) of power received from the first battery (311) through the first stage (313a) to 1 to N (by increasing the voltage N times) and convert the current value to 1 to 1/N, and supply power (e.g., up to about 15 W (= 9 V * 1.67 A)) to the power receiving device (302) through the second stage (313b). Accordingly, the battery provided in the power receiving device (302) can be charged. The first power conversion circuit (313) can convert the voltage value (e.g., about 9 V) of power received from an external electronic device (e.g., TA (travel adapter)) connected to the first power terminal (312a) through the second stage (313b) into a 1 to 1/N ratio and convert the current value into a 1 to N ratio, and supply power (e.g., up to about 15 W (= 4.5 V * 3.33 A)) to the first battery (311) through the first stage (313a). Accordingly, the first battery (311) can be charged through the first power conversion circuit (313).

A second power conversion circuit (e.g., a switching charging circuit) (314) may have its two terminals (314a, 314b) connected to the first battery (311) and the first power terminal (312a), respectively. The second power conversion circuit (314) may convert the voltage value and/or current value of power input from one of the two terminals (313a, 313b) and output it to the other terminal. For example, the second power conversion circuit (314) can boost (e.g., to 5 V) the voltage value of power received from the first battery (311) through the first stage (314a) and supply power (e.g., about 4.5 W (= 5 V * 0.9 A)) to the power receiving device (302) through the second stage (314b). The second power conversion circuit (314) can convert the voltage value and/or current value of power received from an external electronic device (e.g., TA (travel adapter)) connected to the first power terminal (312a) through the second stage (314b) and supply the power to the first battery (311) through the first stage (314a). The second power conversion circuit (314) can include a charging circuit (210) configured in the power management module (188).

The monitoring circuit (315) (e.g., the power gauge (230) of FIG. 2) can monitor the voltage of the battery (311). For example, the monitoring circuit (315) can be connected to both terminals (+ pole, - pole) of the first battery (311) to monitor the voltage of the battery (311) and output the result (data representing the voltage value) to the first processor (333). The first processor (333) can determine the state of charge (SOC) of the battery (311) based on the monitoring result. The processor (333) can control the charging of the first battery (311) based on the SOC. For example, when the voltage of the first battery (311) reaches a target voltage value (e.g., 4.5 V) while the first processor (333) is being charged in a CC (constant current) mode, the first processor (333) can control the charging circuit (e.g., the second power conversion circuit (314)) to gradually lower the current input to the first battery (311) so that the voltage of the first battery (311) is maintained at the target voltage value by switching the charging mode to a CV (constant voltage) mode. The first processor (333) can control the charging circuit (e.g., deactivate the charging circuit) to stop outputting power to the first battery (311) when the current input to the first battery (311) drops to a current value designated for completion of charging (e.g., a topoff current value), thereby completing the charging of the first battery (311). The target voltage value above can be equal to the voltage difference between the positive (+) and negative (-) terminals of the battery when fully charged. Full charge can also refer to the SOC when the battery's charge rate reaches the set maximum charge level without risk of damage or explosion.

The control module (319) can control the discharge of the first battery (311) based on the SOC. Here, the discharge can mean supplying power from the first battery (311) to a system (in other words, a load) of the power supply device (301) (e.g., the first processor (333), the display (318)) or to an external electronic device through the first connector (312). The control module (319) can quantify the SOC as a percentage (%) as an indication of the charge rate of the battery. The control module (319) can display information indicating the charge rate (e.g., percentage) of the first battery (311) on the display (318). The control module (319) can provide information (e.g., percentage) indicating the charge state of the first battery (311) to the power receiving device (302) through the first communication circuit (316). For example, while the first power is supplied from the first battery (311) of the power supply device (301) to the power receiving device (302) through the first power conversion circuit (313) or the second power conversion circuit (314), the control module (319) can provide charging status information of the first battery (311) to the power receiving device (302) through the first communication circuit (316).

The power supply unit (301) may include a power management circuit configured to perform substantially the same function as the power management module (188) of FIG. 1. The first communication circuit (316) may be a circuit configured in the power management circuit. Alternatively, it may be configured as a separate circuit. For example, the first communication circuit (316) may be positioned adjacent to the first connector (312) or may be integrated with the first connector (312). As another example, the first communication circuit (316) and the first power conversion circuit (313) may be configured as a single integrated circuit (IC).

The first communication circuit (e.g., USB controller) (316) can identify the type of the external device connected to the first connector (312) based on data received from the external device through the first data terminal (312b). The control module (319) can check identification information indicating the type of the external device from the communication circuit (316). Based on the identification information, the control module (319) can perform an operation of negotiating between a source that supplies power and a sink that receives power among the two devices (301, 302) by performing communication with the external device according to a power delivery (PD) communication protocol through the first communication circuit (316). After the power supply device (301) is determined as a source and the power reception device (302) is determined as a sink, the control module (319) may perform an operation of negotiating a current value and/or a voltage value of power to be transmitted from the power supply device (301) by performing communication with the power reception device (302) through the first communication circuit (316) according to a PD communication protocol (e.g., power data objects (PDO) or programmable power supply (PPS)). The control module (319) may perform an operation of controlling one of the power conversion circuits (313, 314) to output power having a voltage value and a current value determined by the negotiation result. If the determined voltage and current values are values corresponding to fast charging (e.g., 9 V, 1.66 A), the control module (319) can perform an operation of deactivating the second power conversion circuit (314), activating the first power conversion circuit (313), and supplying power to the power receiving device (302) through the first power terminal (312a) using the activated first power conversion circuit (313). If the determined voltage and current values are values corresponding to normal charging (e.g., 5 V, 1 A), the control module (319) can perform an operation of deactivating the first power conversion circuit (313), activating the second power conversion circuit (314), and supplying power to the power receiving device (302) through the first power terminal (312a) using the activated second power conversion circuit (314).

The sensing circuit (317) may be disposed inside the power supply device (301) (e.g., near the first battery (311), the first power conversion circuit (313), or the second power conversion circuit (314)) and may generate data used to check the internal temperature of the power supply device (301). The control module (319) may check the internal temperature from the data generated by the sensing circuit (317). According to one embodiment, the sensing circuit (317) may include a temperature sensor (e.g., the power gauge (230) of FIG. 2) configured to detect the internal temperature, generate data corresponding to the detected temperature, and output the data to another component (e.g., the first processor (333)). As another example, the control module (319) may request data from the sensing circuit (317) periodically (in a polling manner) or in an interrupt manner to check the internal temperature. As the internal temperature increases, the internal resistance of the electric circuit configured inside the power supply device (301) may linearly increase. For example, as the internal temperature increases, the internal resistance of a lumped element (e.g., an inductor) in the second power conversion circuit (314) increases, and this increase in internal resistance may cause an increase in the potential difference (voltage) between both terminals of the lumped element. According to one embodiment, the sensing circuit (317) may be configured to measure the voltage between both terminals of the electric circuit and generate data corresponding to the voltage. The control module (319) may check the voltage from the data generated by the sensing circuit (317) and, based on the checked voltage value, determine the internal temperature of the power supply device (301).

According to one embodiment, when the internal temperature rises above a specified first threshold temperature value (e.g., about 50 degrees) (or exceeds the first threshold temperature value) while the first power is supplied from the first battery (311) of the power supply device (301) to the power receiving device (302) through the first power conversion circuit (313) or the second power conversion circuit (314), the control module (319) may perform an operation of transmitting a first request message requesting to receive less power from the power supply device (301) to the power receiving device (302) through the first communication circuit (316). In response to receiving the first request message, the power receiving device (302) may receive a second power that is less than the first power from the power supply device (301). If the internal temperature falls below a specified second threshold temperature value (e.g., equal to or lower than the first threshold temperature value (e.g., 48 degrees)) while the second power is being supplied (or is lower than the second threshold temperature value), the control module (319) may perform an operation of transmitting a second request message requesting that the restriction on power reception be lifted to the power receiving device (302) via the first communication circuit (316). In response to receiving the second request message, the power receiving device (302) may receive the first power from the power supply device (301) by lifting the restriction on power reception.

According to one embodiment, when the internal temperature rises above a threshold temperature value (e.g., about 50 degrees) (or exceeds the threshold temperature value) while power is supplied from the first battery (311) of the power supply device (301) to the power receiving device (302) through the first power conversion circuit (313) or the second power conversion circuit (314), the control module (319) may perform an operation of controlling (e.g., deactivating) the corresponding power conversion circuit to stop the power supply.

According to one embodiment, when power is supplied from the first battery (311) of the power supply device (301) to the power receiving device (302) through the first power conversion circuit (313) or the second power conversion circuit (314), and the charge rate of the first battery (311) is below a designated target limit value (e.g., about 30%), the control module (319) may perform an operation of controlling (e.g., disabling) the corresponding power conversion circuit to stop the power supply. For example, the control module (319) (or the first processor (333)) may perform an operation of displaying a user interface (UI) element on the display (318) that allows a user to set how much electrical energy to distribute from the first battery (311) to the power receiving device (302) or how much electrical energy to leave in the first battery (311). For example, the control module (319) (or the first processor (333)) may display an execution screen of an application for power sharing on the display (318) based on the identification of an external device connected to the power supply device (301) via the first connector (312) as a type that supports D2D (Device-to-Device) power sharing. The control module (319) (or the first processor (333)) may include a menu (e.g., a text input window or a scroll bar) on the execution screen that allows a user to set a target limit value and display the menu on the display (318) based on the determination of the power supply device (301) as a source and the determination of the external device (e.g., the power receiving device (302)) as a sink. Alternatively, the control module (319) (or the first processor (333)) may display a pop-up window (or a home screen) including a menu on the display (318). While the UI element is displayed, the control module (319) (or the first processor (333)) can receive user input through the input device. For example, the control module (319) (or the first processor (333)) can receive text data indicating the remaining capacity limit or supply limit of the first battery (311) through the UI element displayed on the display (318). As another example, the control module (319) (or the first processor (333)) can receive voice data indicating the remaining capacity limit or supply limit of the first battery (311) through a microphone. The control module (319) (or the first processor (333)) can perform an operation of determining a target capacity limit value based on the user input. While the power of the first battery (311) is supplied to the power receiving device (302), the control module (319) can check through the monitoring circuit (315) that the charging rate of the first battery (311) has reached the target limit value. Based on the charging rate of the first battery (311) having reached the target limit value, the control module (319) (or the first processor (333)) can control the corresponding power conversion circuit to perform an operation of stopping the power supply to the power receiving device (302).

According to one embodiment, while power is supplied from the first battery (311) of the power supply device (301) to the power receiving device (302) through the first power conversion circuit (313) or the second power conversion circuit (314), the control module (319) (or the first processor (333)) may perform an operation of controlling (e.g., disabling) the corresponding power conversion circuit to stop the power supply when the charge rate of the second battery (341) is equal to or greater than a target charge value (e.g., about 90%). For example, the control module (319) (or the first processor (333)) may display a UI element on the display (318) that allows the user to set how much to charge the second battery (341). As another example, the control module (319) (or the first processor (333)) may display an execution screen of an application for power sharing on the display (318) based on the identification that the external device connected to the power supply device (301) via the first connector (312) supports D2D (device-to-device) power sharing. The control module (319) (or the first processor (333)) may include a menu (e.g., a text input window or a scroll bar) that enables a user to set a target charging value in a UI element (e.g., an execution screen, a pop-up window, or a home screen of a power sharing application) and display the menu on the display (318) based on the identification that the power supply device (301) is a source and the external device is a sink (e.g., a power receiving device (302)). While the UI element is displayed, the control module (319) (or the first processor (333)) may receive a user input through an input device. For example, the control module (319) (or the first processor (333)) can receive text data indicating the charging rate of the second battery (341) through a menu displayed on the display (318). As another example, the control module (319) (or the first processor (333)) can receive voice data indicating the charging rate of the second battery (341) through a microphone. The control module (319) can determine a target charging value based on a user input. While the electric energy accumulated in the first battery (311) is supplied to the power receiving device (302), the control module (319) can perform an operation of checking the charging rate of the second battery (341) through the first communication circuit (316). Based on the charge rate of the second battery (341) reaching the target charge value, the control module (319) (or the first processor (333)) can perform an operation of controlling the corresponding power conversion circuit to stop supplying power to the power receiving device (302).

According to one embodiment, even if the charge rate of the second battery (341) does not reach the target charge value, based on the charge rate of the first battery (311) reaching the target limit value, the control module (319) may control the corresponding power conversion circuit to perform an operation of stopping the supply of power to the power receiving device (302). For example, the control module (319) (or the first processor (333)) may determine whether the charge rate of the first battery (311) is less than or equal to the target limit value based on information received from the monitoring circuit (315). If the charge rate of the first battery (311) is less than or equal to the target limit value, the control module (319) (or the first processor (333)) may stop the supply of power to the power receiving device (302). If the charging rate of the first battery (311) exceeds the target limit value, the control module (319) (or the first processor (333)) can determine whether the charging rate of the second battery (341) is equal to or greater than the target charging value based on information about the charging rate of the second battery (341) received through the first communication circuit (316). If the charging rate of the second battery (341) is equal to or greater than the target charging value, the control module (319) (or the first processor (333)) can stop supplying power to the power receiving device (302). If the charging rate of the second battery (341) is less than the target charging value, the first processor (333) can maintain supplying power to the power receiving device (302).

According to one embodiment, the prediction module (320) (or the first processor (333)) may perform an operation of predicting a charging rate of the second battery (341) when electric energy is discharged from the first battery (311) by the target discharge value based on a user input and status information of the second battery (341) received from the power receiving device (302). The prediction module (320) (or the first processor (333)) may perform an operation of displaying information representing the predicted charging rate on the display (318). For example, the prediction module (320) (or the first processor (333)) may display a UI element on the display (318) that allows the user to set how much electric energy to distribute from the battery (311) to the power receiving device (302) or how much electric energy to leave in the first battery (311). For example, the prediction module (320) (or the first processor (333)) may display an execution screen of an application for power sharing on the display (318) based on the identification that an external device connected to the power supply device (301) via the first connector (312) supports D2D (device-to-device) power sharing. The prediction module (320) (or the first processor (333)) may include a menu (e.g., a text input window or a scroll bar) that enables a user to set a target discharge value in a UI element (e.g., an execution screen, a pop-up window, or a home screen of a power sharing application) and display the menu on the display (318) based on the identification that the power supply device (301) is determined as a source and the external device (e.g., the power receiving device (302)) is determined as a sink. While the UI element is displayed, the prediction module (320) (or the first processor (333)) may receive a user input through an input device. For example, the prediction module (320) (or the first processor (333)) may receive text data (text indicating the amount of power) indicating how much electric energy to discharge from the first battery (311) through a menu displayed on the display (318). As another example, the prediction module (320) (or the first processor (333)) may receive voice data indicating the amount of power to discharge from the first battery (311) through a microphone. The prediction module (320) (or the first processor (333)) may perform an operation of checking the status information of the second battery (341) including information indicating the maximum chargeable capacity (e.g., a numerical value in units of mAh (milli ampere hour)) of the second battery (341) and information indicating the charge rate (e.g., SOC) of the second battery (341) from the power receiving device (302) through the first communication circuit (316). The prediction module (320) (or the first processor (333)) may perform an operation of determining a predicted charging rate of the second battery (341) when electric energy is discharged from the first battery (311) by the target discharge value using the status information and the target discharge value. The prediction module (320) (or the first processor (333)) may perform an operation of including information indicating the predicted charging rate in an execution screen (or a pop-up window) and displaying the information on the display (318).

According to one embodiment, the prediction module (320) (or the first processor (333)) may include a prediction AI model (or the first AI model) (320a) trained to predict a charging rate. The prediction module (320) (or the first processor (333)) may input a target discharge value determined based on a user input and status information of the second battery (341) received from the power receiving device (302) into the prediction AI model, and may obtain a predicted charging rate from a value output from the prediction AI model (320a) as a result of the input. The prediction module (320) (or the first processor (333)) may include information indicating the predicted charging rate in an execution screen (or a pop-up window) and display it on the display (318).

According to one embodiment, the control module (319) (or the first processor (333)) can check the status of the first battery (311) through the monitoring circuit (315) while power is supplied from the first battery (311) of the power supply device (301) to the power receiving device (302) through the first power conversion circuit (313) or the second power conversion circuit (314). The control module (319) (or the first processor (333)) can control the corresponding power conversion circuit to stop the power supply to the power receiving device (302) based on the confirmation that the electric energy is discharged from the first battery (311) by the target discharge value. In addition, the control module (319) (or the first processor (333)) can check the charge rate of the second battery (241) through the first communication circuit (316). For example, the control module (319) (or the first processor (333)) may transmit a request message requesting to inform the charging rate of the second battery (341) to the power receiving device (302) through the first communication circuit (316). In response to the request message, the control module (319) may receive a response message including information indicating the charging rate of the second battery (241) from the power receiving device (302) through the first communication circuit (316). The control module (319) (or the first processor (333)) may use the difference (error) between the predicted charging rate and the actual charging rate identified from the response message as learning data for learning the prediction AI model (320a). The success rate of prediction may be improved by retraining the prediction AI model (320a) using this difference value.

According to one embodiment, the recommendation module (321) (or the first processor (333)) may generate recommendation information for setting a target value (e.g., the target limit value or target discharge value described above) based on history information related to power sharing of the first battery (311). The recommendation module (321) (or the first processor (333)) may display the generated recommendation information on the display (318). For example, the recommendation module (321) may store history information including a supply history indicating when and how much electric energy accumulated in the first battery (311) was supplied (shared) to an external device, a limit history indicating how much electric energy was left in the first battery (311) when power was shared with an external device, and identification information of the external device that received power, in the first memory (322). The recommendation module (321) (or the first processor (333)) may generate recommendation information using the history information. For example, the recommendation module (321) (or the first processor (333)) may check the target value with the highest setting frequency and/or the most recently set target value in the supply history related to the power receiving device (302) from the history information and determine this as the recommendation information. The recommendation module (321) (or the first processor (333)) may include the recommendation information in a UI element (e.g., an execution screen or pop-up window of an application for power sharing) and display it on the display (318). The control module (319) (or the first processor (333)) may determine the target value described in the above-described paragraph from the recommendation information based on a user input received through an input device.

According to one embodiment, the recommendation module (321) (or the first processor (333)) may include a recommendation AI model (or a second AI model) (321a) trained to recommend to the user the amount of power to be supplied from the first battery (311) to an external device. The recommendation module (321) (or the first processor (333)) may input the history information described in the above-described paragraph with respect to power sharing of the first battery (311) into the recommendation AI model (321a), and obtain recommendation information from a value output from the recommendation AI model (321a) as a result of the input. The recommendation module (321) (or the first processor (333)) may display the recommendation information provided by the recommendation AI model (321a) on the display (318) by including it in a UI element (e.g., an execution screen or a pop-up window of an application for power sharing).

According to one embodiment, the recommendation module (321) (or the first processor (333)) may use the target values (e.g., target limit value and/or target discharge value) selected by the user for power sharing as training data for training the recommendation AI model (321a). By retraining the recommendation AI model (321a) based on the target values, the probability that the user will accept the AI recommendation may be improved.

The power receiving device (302) may include a second battery (341), a second connector (342), a charging circuit (343), a second communication circuit (344), a second memory (355), and a second processor (366). The charging circuit (343), the second memory (355), and the second processor (366) may be implemented in substantially the same manner as the charging circuit (210), the memory (130), and the processor (120), thereby performing the same functions. Instructions may be stored in the second memory (355) in the power receiving device (302). The instructions may be executed by the second processor (366), thereby allowing the power receiving device (302) to perform data communication with the power supply device (301) and receive power from the power supply device (301).

The second connector (342) may include a second power terminal (342a) for transmitting or receiving power to or from an external electronic device, and a second data terminal (342b) for data communication with the external electronic device. For example, the second connector (342) may be configured as a socket according to a universal serial bus (USB) Type-C and may be coupled with a plug of a cable (303). Among the pins of the USB Type-C socket, the VBUS pin may be used as the second power terminal (342a), and the CC pin and/or the differential signal pin (DP (D+), DN (D-)) may be used as the second data terminal (342b).

The charging circuit (343) may have its two terminals (343a, 343b) connected to the second power terminal (342a) and the second battery (341), respectively. The charging circuit (343) may include a buck boost converter configured to convert a current value and/or a voltage value of power received from the first terminal (343a) and output the converted power to the second battery (341) through the second terminal (343b). For example, the charging circuit (343) may support constant current (CC) and constant voltage (CV) charging based on the control of the second processor (366). While the charging mode is set to the CC mode, the charging circuit (343) can constantly maintain the current of the power output from the charging circuit (343) to the second battery (341) at a charging current value set by the second processor (366) so that the voltage of the second battery (341) rises to a designated target voltage value. When the voltage of the second battery (341) reaches the target voltage value during charging of the second battery (341) and the charging mode is switched from the CC mode to the CV mode, the charging circuit (343) can gradually lower the current of the power output from the charging circuit (343) to the second battery (341) under the control of the second processor (366) so that the voltage of the second battery (341) is maintained at the target voltage value. When the current of the power input to the second battery (341) during charging of the second battery (341) in CV mode decreases to a current value designated for completion of charging (e.g., topoff current value), the charging circuit (343) can complete charging of the second battery (341) by stopping the output of power to the second battery (341) based on the control of the second processor (366).

The power receiving device (302) may include a power management circuit configured to perform substantially the same function as the power management module (188) of FIG. 1. The second communication circuit (344) may be a circuit configured in the power management circuit. Alternatively, it may be configured as a separate circuit. For example, the second communication circuit (344) may be positioned adjacent to the second connector (342) or may be integrated with the second connector (342). As another example, the second communication circuit (344) and the charging circuit (343) may be configured as a single integrated circuit (IC).

A second communication circuit (e.g., a USB controller) (344) can identify the type of an external device connected to the second connector (342) based on data received from the external device through the second data terminal (342b). The communication circuit (344) can transmit identification information indicating the type of the external device to the second processor (366). Based on the identification information, the second processor (366) can perform a negotiation operation to determine a source and a sink among the two devices (301, 302) by performing communication with the external device through the second communication circuit (344) according to a power delivery (PD) communication protocol. After the power supply device (301) is determined as a source and the power reception device (302) is determined as a sink, the second processor (366) may perform an operation of negotiating a current value and/or a voltage value of power to be received by the power reception device (302) by performing communication with the power supply device (301) through the second communication circuit (344) according to a PD communication protocol (e.g., power data objects (PDO) or programmable power supply (PPS)). The second processor (366) may control the charging circuit (343) to receive power having a voltage value and/or a current value determined by the negotiation result.

At least one of the modules (319, 320, 321) described above may be stored as a command in the memory of the power supply device (301). Here, the memory may include the first memory (888) and/or the internal memory of the processor (899). For example, the command may be stored in the first memory (322). As another example, the command may be stored in the internal memory of the first processor (322). As another example, the command may be partially stored in the first memory (322) and the internal memory of the first processor (322). The command, when individually or collectively executed by at least one processor (e.g., the first processor (322)), may cause the power supply device (301) to perform a given operation (e.g., power supply control, charging rate prediction, or target value recommendation).

According to one embodiment, at least one of the modules described above (e.g., control module (319), prediction module (320), recommendation module (321)) may be included in an external device (e.g., server (108) or power receiving device (302)) instead of the power supply device (301).

According to one embodiment, a prediction module implemented substantially identically to the prediction module (320) may be configured in an external device. For example, when the external device is a power receiving device (302), the power supply device (301) may transmit the target discharge value described in the above-described paragraph to the power receiving device (302) via the first communication circuit (316). The power receiving device (302) may obtain a predicted charging rate using the target discharge value provided from the power supply device (301) and the status information of the second battery (341), and transmit information representing the same to the power supply device (301) via the second communication circuit (344). The power supply device (301) may include the predicted charging rate information provided from the power receiving device (302) via the first communication circuit (316) in a UI element and display it on the display (318). For example, if the external device is a server, the power supply device (301) can transmit the target discharge value and the status information of the second battery (341) provided from the power receiving device to the server through a communication circuit (e.g., the wireless communication module (192) of FIG. 1) separately provided in the power supply device (301). The power supply device (301) can display the predicted charging rate information provided from the server through the communication circuit in a UI element on the display (318).

According to one embodiment, a recommendation module implemented substantially identically to the recommendation module (321) may be configured in an external device. For example, if the external device is a power receiving device (302), the power supply device (301) may transmit the history information described in the above-described paragraph to the power receiving device (302) via the first communication circuit (316). The power receiving device (302) may generate recommendation information using the history information provided from the power supply device (301) and transmit the recommendation information to the power supply device (301) via the second communication circuit (344). The power supply device (301) may include the recommendation information provided from the power receiving device (302) via the first communication circuit (316) in a UI element and display the same on the display (318). For example, if the external device is a server, the power supply device (301) can transmit history information to the server through a communication circuit (e.g., a wireless communication module (192) of FIG. 1) separately provided in the power supply device (301).
