In one embodiment, the processor (120) may supply power to the battery (189) and / or the load (system (340)) using the first charger (310) or the second charger (320) based on an output voltage or battery voltage that the external device (301) can supply if the connected external device (301) is not a PPS charger. The processor (120) may charge the battery (189) using the first charger (310) and supply load power to the system (340). A non-PPS charger may include, for example, a charger that provides at least two fixed output voltages, such as about 9 V and / or about 5 V (e.g., a “first charger” hereinafter), or a charger that can provide an output voltage between about 3.5 V and about 22 V (e.g., a “second charger” hereinafter), or a charger that provides a single fixed output voltage, such as about 5 V (e.g., a “third charger” hereinafter).

The first charger (310) may include a charge controller (not shown). The first charger (310) may charge the battery (189) by adjusting an input voltage or input current input from an external device (301) via a USB interface (310).

[0071] According to one embodiment, the second charger (320) may be a direct charger that supports direct charging (hereinafter, “DC charging”) using a switched cap (capacitor) divider method. According to one embodiment, the second charger (320) may include a power converter that lowers an input voltage input from an external device (301) by a specified ratio and outputs it, and increases an input current input from the external device (301) by the specified ratio and outputs it.

[0075] Figure 4 is a flowchart illustrating a driving method of an electronic device (101) according to one embodiment.

[0076] The operations illustrated in FIG. 4 may be performed by instructions stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, when the instructions are executed by a processor (120) (e.g., the processor (120) of FIG. 1), the instructions may cause the electronic device (101) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 4.

[0077] At least some of the operations illustrated in FIG. 4 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 4.

[0078] According to one embodiment, at least some of the operations illustrated in FIG. 4 may be performed sequentially.

[0079] According to one embodiment, at least some of the operations illustrated in FIG. 4 can be performed in parallel (simultaneously).

[0080] Hereinafter, a driving method of an electronic device (101) according to one embodiment will be described with reference to FIG. 4.

[0081] In operation 410, an electronic device (101) according to one embodiment (e.g., the electronic device (101) of FIG. 1) may determine whether an external device (301) (e.g., the external device (301) of FIG. 3) is a first device that supports a charge control function that varies a supply voltage in a specified unit. For example, the charge control function may be a function that can vary an output voltage in units less than about 0.1 V.

[0082] The term “charge control function” used in the present disclosure refers to a function that varies the supply voltage in a specified unit, and can be used interchangeably with terms such as “PPS function” or “high-resolution voltage variation function.” Hereinafter, the description of the present disclosure will describe the charge control function as a PPS function. However, the charge control function is not limited to the term “PPS function,” and any term may be used as long as it is a function that can vary the output voltage in units of less than about 0.1 V.

[0083] It can be confirmed whether the first device supports the PPS function. For example, when the electronic device (101) is connected to an external device (301) by a wire through a charging interface, the type of the external device (301) can be confirmed. The electronic device (101) can confirm whether the connected external device (301) is a PPS charger capable of varying the output current and output voltage. The PPS charger can adjust the output voltage in a range of about 3 V to about 21 V based on the control of the electronic device (101). The PPS charger can supply an output voltage in a specified range to the electronic device (101) that supports direct charging (hereinafter, “DC charging”) using a switched cap (capacitor) divider method, and the output voltage in the specified range can be in a range of about 3 V to about 21 V. The PPS charger can adjust the output voltage in a range of about 3 V to about 21 V and supply the adjusted output voltage to the electronic device (101).

[0084] In operation 420, the electronic device (101) according to one embodiment can check a plurality of output voltages that the external device (301) can output as a type of the external device (301), if the external device (301) is not a first device that supports the PPS function.

[0085] According to one embodiment, when an external device (301) is connected, the electronic device (101) can receive information related to power (voltage, current) that the external device (301) can supply through power delivery (PD) communication, VBUS communication, or VBUS voltage. For example, power data object (PDO) information of the external device (301) can be obtained.

[0086] According to one embodiment, if the acquired PDO government does not have augmented power data object (APDO) information, the electronic device (101) may determine that the external device (301) is not the first device supporting the PPS function. If the electronic device (101) determines that the external device (301) is not the first device, the electronic device (101) may check the FPDO (fixed power data object) information to determine a plurality of output voltages, a plurality of output currents, and a maximum output current that the external device (301) can output. For example, the electronic device (101) may check at least some of a 9V PDO, a 12V PDO, a 15V PDO, or a 20V PDO as the FPDO information. The electronic device (101) may check whether the external device (301) is capable of 5V output, 9V output, 15V output, or 20V output according to the checked FPDO information.

[0087] In operation 430, the electronic device (101) according to one embodiment can check the magnification values ​​for a specified magnification that the second charger (320) (e.g., the second charger (320) of FIG. 3) can vary.

[0088] In one embodiment, the second charger (320) may include a 2:1 voltage divider that reduces the input voltage by half and increases the input current by two times. In various embodiments, the second charger (320) is not limited to including a 2:1 voltage divider, but may be variously designed to include a 3:1 voltage divider that reduces the input voltage by one-third and increases the input current by three times, or a 4:1 voltage divider that reduces the input voltage by one-quarter and increases the input current by four times. The second charger (320) may provide multiple modes, such as a 2:1 voltage divider, a 3:1 voltage divider, or a 4:1 voltage divider, and the mode may be determined according to a setting of a processor of the electronic device (101) (e.g., the processor (120) of FIG. 1 ).

[0089] An electronic device (101) according to one embodiment can check whether a N:1 magnification can be supported, whether a 4:1 magnification can be supported, whether a 2:1 magnification can be supported, or whether a 1:1 magnification can be supported as magnification values ​​for a specified magnification that the second charger (320) can vary.

[0090] In operation 440, the electronic device (101) according to one embodiment may obtain a charging profile mapped with a charging current and a charging voltage for each section of the voltage level of the battery (189) (e.g., the battery (189) of FIG. 3). For example, the electronic device (101) may store a charging profile related to the battery (189) in advance in the memory (130). The charging profile may define a maximum charging current, constant current charging, or constant voltage charging for each section according to the voltage level of the battery (189).

[0091] The term “charge profile” as used in this disclosure may be used interchangeably with terms such as “battery charge profile.”

[0092] In operation 450, the electronic device (101) according to one embodiment may obtain a designated table in which a charging profile is mapped according to the type of the external device (301). The electronic device (101) according to one embodiment may obtain a designated charging profile (e.g., a designated table) based on information (e.g., source capability, PDO (power data object)) based on the external device (301) and information on a rate that the second charger (320) can vary. For example, the external device (301) may be of various types even if it is a device that does not support the PPS function. The electronic device (101) according to one embodiment may store designated tables in advance in the memory (130) as information related to external devices (301) that do not support the PPS function. For example, if the external device (301) is a device that supports output voltages of PDO 20 V, PDO 15 V, and PDO 9 V, the electronic device (101) may store a table such as Table 1 in advance. Columns 1 and 2 of Table 1 may represent a portion of a charging profile of the electronic device (101), and column 3 of Table 1 may represent candidate settings that map the charging profile in response to the external device (301) that supports output voltages of PDO 20 V, PDO 15 V, and PDO 9 V. In the present disclosure, the candidate settings mean some combinations that satisfy the charging current defined by the charging profile among combinations of output voltages of the external device (301) and driving ratios of the second charger (320). For example, looking at the second row of Table 1, in the first section of the charging profile, the charging current is defined as “I1”, and candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), and candidate 1-3 (20 V, 4:1) are stored as candidate settings that do not exceed this charging current.Here, candidate 1-1 (9V, 2:1) may mean a combination in which the output voltage of the external device (301) is set to 9V and the driving ratio of the second charger (320) is set to 2:1. The second charger (320) of the electronic device (101) operating based on candidate 1-1 (9V, 2:1) may convert the 9V of the external device (301) to 4.5V and output it, and may double the output current of the external device (301).

[0093] Sections of the charging profile Charging current (e.g. maximum charging current) Candidate combinations of voltage of external device (301) (PDO 20V, PDO 15V, PDO 9V) and ratio (2:1, 4:1) of second charger (320) First section I1 Candidate 1-1: 9V, 2:1 Candidate 1-2: 15V, 4:1 Candidate 1-3: 20V, 4:1 Second section I2 Candidate 2-1: 9V, 2:1 Candidate 2-2: 20V, 4:1 Third section I3 Candidate 3-1: 9V, 2:1 Candidate 3-2: 20V, 4:1 Fourth section I4 Candidate 4-1: 9V, 2:1 Candidate 4-2: 20V, 4:1 Fifth section I5 Candidate 5-1: 9V, 2:1 Candidate 5-2: 20V, 4:1 Section 6 I6 Candidate 6-1: 20V, 4:1

[0094] According to one embodiment, the electronic device (101) may store tables mapping charging profiles of various types of external devices (301) to the corresponding external devices (301) in addition to the designated tables as in Table 1. For example, if the external device (301) is a device that supports output voltages of PDO 15 V and PDO 9 V, the electronic device (101) may further store a table as in Table 2. Columns 1 and 2 of Table 2 may represent a portion of the charging profile of the electronic device (101), and column 3 of Table 2 may represent candidate settings in which the electronic device (101) maps the charging profile corresponding to the external device (301) that supports output voltages of PDO 15 V and PDO 9 V. For example, looking at the second row of Table 2, in the first section of the charging profile, the charging current is defined as “I1”, and candidate 1-1 (9 V, 2:1) and candidate 1-2 (15 V, 4:1) are stored as candidate settings that do not exceed this charging current.

[0095] Section charging current of the charging profile Candidate combination of voltage of external device (301) (15V, PDO 9V) and ratio (2:1, 4:1) of second charger (320) 1st section I1 Candidate 1-1: 9V, 2:1 Candidate 1-2: 15V, 4:1 2nd section I2 Candidate 2-1: 9V, 2:1 3rd section I3 Candidate 3-1: 9V, 2:1 4th section I4 Candidate 4-1: 9V, 2:1 5th section I5 Candidate 5-1: 9V, 2:1 6th section I6 Candidate 6-1: 20V, 4:1

[0096] In operation 460, the electronic device (101) according to one embodiment may check the voltage level of the battery (189). For example, the electronic device (101) may check the voltage level of the battery (189) and check which section among the sections defined in the charging profile the current voltage level of the battery (189) corresponds to. In operation 470, the electronic device (101) according to one embodiment may determine, based on the charging profile, a charging current value corresponding to the type of the external device (301) and the checked voltage level of the battery (189). For example, if the external device (301) is a device that supports output voltages of PDO 20 V, PDO 15 V, and PDO 9 V, the electronic device (101) may refer to a table such as Table 1 from the memory (130). According to one embodiment, the electronic device (101) can check, in a designated table, a section corresponding to the current voltage level of the battery (189) and candidate settings defined in the section. For example, if the current voltage level of the battery (189) is the first section of the charging profile, the electronic device (101) can select any one of candidate settings pre-stored in the table, such as candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), or candidate 1-3 (20 V, 4:1).

[0097] In operation 480, the electronic device (101) according to one embodiment may determine, based on the determined charging current value, a first output voltage from among a plurality of output voltages that the external device (301) may output, and a first multiplier value from among multiplier values ​​for a specified multiplier that the second charger (320) may vary. When selecting one of the selected candidate settings, the electronic device (101) may select a candidate setting in which the second charger (320) supplies the largest charging current value to the battery (189). For example, the electronic device (101) may select candidate 1-1 (9 V, 2:1) among candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), or candidate 1-3 (20 V, 4:1) that satisfy the requirement of charging current “I1” in the first section, if the charging current according to candidate 1-1 (9 V, 2:1) is the largest. The electronic device (101) may determine the first output voltage and the first multiplier value according to the selected candidate 1-1 (9 V, 2:1).

[0098] In operation 490, the electronic device (101) according to one embodiment can control the external device (301) to cause the external device (301) to output a first output voltage. In the present disclosure, the electronic device (101) controlling the external device (301) can be interpreted to mean that the electronic device (101) transmits a request signal to the external device (301). For example, the electronic device (101) can transmit the request signal to the external device (301), and the external device (301) can perform an operation requested by the electronic device (101) in response to the request signal. For example, the electronic device (101) can transmit the request signal to cause the external device (301) to output 9 V according to the selected candidate 1-1 (9 V, 2:1). The electronic device (101) can control the second charger (320) while the external device (301) outputs the first output voltage so that the second charger (320) charges the battery (189) according to the first multiplier value. The electronic device (101) according to one embodiment can transmit information (or data) related to a power change to the external device (301). The electronic device (101) according to one embodiment can request information (or data) related to a power change from the external device (301).

[0099] FIG. 5 is a flowchart illustrating an operation of an electronic device (101) according to one embodiment of the present invention to determine a charging current value.

[0100] The operations illustrated in FIG. 5 may be performed by instructions stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, when the instructions are executed by a processor (120) (e.g., the processor (120) of FIG. 1), the instructions may cause the electronic device (101) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 5.

[0101] At least some of the operations illustrated in FIG. 5 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 5.

[0102] According to one embodiment, at least some of the operations illustrated in FIG. 5 may be performed sequentially.

[0104] Hereinafter, with reference to FIG. 5, an operation of an electronic device (101) according to one embodiment to determine a charging current value will be described.

[0105] In operation 510, an electronic device (101) according to one embodiment (e.g., the electronic device (101) of FIG. 1) may determine a section of a charging profile corresponding to a voltage level of a battery (189) (e.g., the battery (189) of FIG. 3) from a specified table (e.g., Table 1). For example, the electronic device (101) may check the voltage level of the battery (189) and determine which section among the sections defined in the charging profile the current voltage level of the battery (189) corresponds to.

[0106] In operation 520, the electronic device (101) according to one embodiment may determine a plurality of candidate settings that combine one output voltage among a plurality of output voltages and one multiplier value among a plurality of multiplier values ​​in a section of the identified charging profile.

[0107] According to one embodiment, the electronic device (101) can check, from a designated table, a section corresponding to the current voltage level of the battery (189) and candidate settings defined in the section. For example, if the current voltage level of the battery (189) is the first section of the charging profile, the electronic device (101) can obtain candidate settings pre-stored by the table, such as candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), or candidate 1-3 (20 V, 4:1).

[0108] In operation 530, the electronic device (101) according to one embodiment may control the external device (301) to sequentially vary the output voltage based on a plurality of candidate settings during a test period, and may control the second charger (320) (e.g., the second charger (320) of FIG. 3) to sequentially vary the multiplier value. For example, the test period may be a period temporarily performed before the electronic device (101) makes a full-scale request for power supply to the external device (301). The electronic device (101) may charge the battery (189) according to the plurality of candidate settings during the test period to determine an optimal candidate setting among candidate settings pre-stored in a table. For example, if the electronic device (101) has three candidate settings (candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), or candidate 1-3 (20 V, 4:1)), the test period can be divided into three periods, and the battery (189) charging can be tested based on the candidate settings for each divided period.

[0109] The term “test period” used in the present disclosure means a period during which the electronic device (101) controls the external device (301) so that the external device (301) sequentially varies the output voltage corresponding to each of a plurality of candidate settings, and may be used interchangeably with terms such as “charge setting period”.

[0110] In the present disclosure, the electronic device (101) controlling the external device (301) can be interpreted to mean that the electronic device (101) transmits a request signal to the external device (301).

[0111] In operation 540, the electronic device (101) according to one embodiment may determine a first candidate setting that satisfies a specified condition from among a plurality of candidate settings during a test period. For example, the electronic device (101) may finally select a candidate setting that satisfies the requirements of the charging profile while best satisfying the specified condition among the charges of the battery (189) performed during the test period. For example, the specified condition may include a condition in which the temperature of the second charger (320) does not rise above a threshold temperature, or a condition in which the charging current is the highest. For example, the second charger (320) may include a protection circuit (not shown) that limits the charging current from becoming an overcurrent corresponding to a specified current or more. The protection circuit of the second charger (320) may operate when the charging current is an overcurrent, thereby performing a function of reducing the charging current to a preset current or less. The operation of this protection circuit may generate heat and may cause the temperature of the second charger (320) to increase. According to one embodiment, the electronic device (101) may exclude the candidate setting by considering that the protection circuit has been activated because the charging current is overcurrent when the temperature of the second charger (320) rises above the threshold temperature. In operation 550, the electronic device (101) according to one embodiment may determine the first output voltage and the first multiplier value based on the determined first candidate setting. For example, the electronic device (101) may select candidate 1-1 (9 V, 2:1) among candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), or candidate 1-3 (20 V, 4:1) that satisfy the requirement of the charging current “I1” in the first section, if the charging current according to candidate 1-1 (9 V, 2:1) is the largest. The electronic device (101) can determine the first output voltage and the first multiplication value according to the selected candidate 1-1 (9 V, 2:1).An electronic device (101) according to one embodiment can transmit information (or data) related to a power change to an external device (301). An electronic device (101) according to one embodiment can request information (or data) related to a power change from an external device (301).

[0112] FIG. 6 is a flowchart illustrating an operation of an electronic device (101) according to one embodiment of the present invention to determine candidate settings based on a temperature change of a second charger (320).

[0113] The operations illustrated in FIG. 6 may be performed by instructions stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, when the instructions are executed by a processor (120) (e.g., the processor (120) of FIG. 1), the instructions may cause the electronic device (101) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 6.

[0114] At least some of the operations illustrated in FIG. 6 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 6.

[0115] According to one embodiment, at least some of the operations illustrated in FIG. 6 may be performed sequentially.

[0116] According to one embodiment, at least some of the operations illustrated in FIG. 6 can be performed in parallel (simultaneously).

[0117] Hereinafter, with reference to FIG. 6, an operation of an electronic device (101) according to one embodiment to determine candidate settings according to a temperature change of a second charger (320) will be described.

[0118] In operation 610, an electronic device (101) according to one embodiment (e.g., the electronic device (101) of FIG. 1) may detect a temperature change of a second charger (320) (e.g., the second charger (320) of FIG. 3) for each of a plurality of candidate settings during a test period. For example, if there are three candidate settings (candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), or candidate 1-3 (20 V, 4:1)), the electronic device (101) may divide the test period into three periods and test the charging of the battery (189) based on the candidate settings for each of the divided periods. The electronic device (101) may detect a temperature change of the second charger (320) while charging the battery (189) for each candidate setting.

[0119] In operation 620, the electronic device (101) according to one embodiment may exclude a candidate setting that causes a temperature change of the second charger (320) to exceed a specified first threshold value from among a plurality of candidate settings. For example, if there is a candidate setting that causes a temperature change of the second charger (320) to exceed the first threshold value during a test period, the electronic device (101) may exclude the corresponding candidate setting from among the candidates for charging the battery (189). For example, if there are three candidate settings (candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), or candidate 1-3 (20 V, 4:1)), and the temperature change of the second charger (320) exceeds the first threshold value when charging the battery (189) according to candidate 1-3 (20 V, 4:1), the electronic device (101) may not select candidate 1-3 (20 V, 4:1). The fact that the temperature change of the second charger (320) exceeds the first threshold value may mean that charging the battery (189) according to the corresponding candidate setting exceeds the charging current defined in the charging profile. Therefore, if there is a candidate setting in which the temperature change of the second charger (320) exceeds the first threshold value, the electronic device (101) may exclude the corresponding candidate setting.

[0120] The electronic device (101) can determine one of the candidate settings that is not excluded according to the above scenario among the candidate settings as a setting for charging the battery (189).

[0121] FIG. 7 is a flowchart illustrating an operation of an electronic device (101) according to one embodiment to determine candidate settings according to a maximum charging current defined in a charging profile.

[0122] The operations illustrated in FIG. 7 may be performed by instructions stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, when the instructions are executed by a processor (120) (e.g., the processor (120) of FIG. 1), the instructions may cause the electronic device (101) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 7.

[0123] At least some of the operations illustrated in FIG. 7 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 7.

[0124] According to one embodiment, at least some of the operations illustrated in FIG. 7 may be performed sequentially.

[0125] According to one embodiment, at least some of the operations illustrated in FIG. 7 can be performed in parallel (simultaneously).

[0126] Hereinafter, referring to FIG. 7, an operation of an electronic device (101) according to one embodiment to determine candidate settings according to a maximum charging current defined in a charging profile will be described.

[0127] In operation 710, an electronic device (101) according to an embodiment (e.g., the electronic device (101) of FIG. 1) may detect a charging current input to a battery (189) from a second charger (320) (e.g., the second charger (320) of FIG. 3) for each of a plurality of candidate settings during a test period. For example, if there are three candidate settings (candidate 1-1 (9 V, 2:1), candidate 1-2 (15 V, 4:1), or candidate 1-3 (20 V, 4:1)), the electronic device (101) may divide the test period into three periods and test the charging of the battery (189) based on the candidate settings for each of the divided periods. The electronic device (101) may detect a charging current input to the battery (189) while charging the battery (189) according to each candidate setting.

[0128] In operation 720, the electronic device (101) according to one embodiment may exclude, from among a plurality of candidate settings, a candidate setting that causes the charging current to exceed the maximum charging current defined in the charging profile. Although the table stored in the memory (130) maps charging profiles to each type of external device (301) and stores candidate settings that do not exceed the charging current defined in the charging profile, abnormal cases may occur in an actual charging environment. Therefore, if there is a candidate setting that causes the charging current to exceed the maximum charging current defined in the charging profile during the test period, the electronic device (101) may exclude the corresponding candidate setting from the candidates for charging the battery (189).

[0129] The electronic device (101) can determine one of the candidate settings that is not excluded according to the above scenario among the candidate settings as a setting for charging the battery (189).

[0130] FIG. 8 is a flowchart illustrating an operation of an electronic device (101) according to one embodiment of the present invention to change the output voltage of an external device (301) and the multiplier value of a second charger (320) as the charging section of the voltage level of a battery (189) changes.

[0131] The operations illustrated in FIG. 8 may be performed by instructions stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, when the instructions are executed by a processor (120) (e.g., the processor (120) of FIG. 1), the instructions may cause the electronic device (101) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 8.

[0132] At least some of the operations illustrated in FIG. 8 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 8.

[0133] According to one embodiment, at least some of the operations illustrated in FIG. 8 may be performed sequentially.

[0134] According to one embodiment, at least some of the operations illustrated in FIG. 8 can be performed in parallel (simultaneously).

[0135] Hereinafter, referring to FIG. 8, an operation of an electronic device (101) according to one embodiment to change the output voltage of an external device (301) and the multiplication value of a second charger (320) as the charging section of the voltage level of a battery (189) changes will be described.

[0136] In operation 810, an electronic device (101) according to an embodiment (e.g., the electronic device (101) of FIG. 1) may check a voltage level of a battery (189) (e.g., the battery (189) of FIG. 3). For example, after the electronic device (101) charges the battery (189) according to a first combination of the voltage of the initially set external device (301) and the driving ratio of the second charger (320), if the charging section of the voltage level of the battery (189) changes, the electronic device (101) may change the setting again. If the charging section of the voltage level changes, the electronic device (101) may check the voltage level of the battery (189) and check which section among the sections defined in the charging profile the current voltage level of the battery (189) corresponds to.

[0137] In operation 820, the electronic device (101) according to one embodiment may determine a charging current value corresponding to the supply power (voltage, current) information of the external device (301) (or the type of the external device (301)) and the voltage level of the identified battery (189) based on a specified table. For example, if the voltage level of the current battery (189) has changed from the first section to the second section of the charging profile, any one of candidate settings pre-stored by the table (e.g., Table 1) Candidate 2-1 (9 V, 2:1) or Candidate 2-2 (20 V, 4:1) may be selected. In selecting any one of the selected candidate settings, the electronic device (101) may re-perform at least some of the operations described with reference to FIGS. 5 to 7.

[0138] In operation 830, the electronic device (101) according to one embodiment may determine, based on the determined charging current value, a second output voltage among a plurality of output voltages that the external device (301) may output, and a second multiplier value among multiplier values ​​for a specified multiplier that the second charger (320) may vary.

[0139] In operation 840, the electronic device (101) according to one embodiment may control the external device (301) (e.g., the external device (301) of FIG. 3) to cause the external device (301) to output a second output voltage. The electronic device (101) according to one embodiment may transmit information (or data) related to a power change to the external device (301). The electronic device (101) according to one embodiment may request information (or data) related to a power change from the external device (301). In the present disclosure, the electronic device (101) controlling the external device (301) may be interpreted to mean that the electronic device (101) transmits a request signal to the external device (301).

[0140] FIG. 9 is a flowchart illustrating an operation of an electronic device (101) according to one embodiment of the present invention to change the output voltage of an external device (301) and the multiplier value of a second charger (320) according to a change in the amount of charging current input to a battery (189).

[0141] The operations illustrated in FIG. 9 may be performed by instructions stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, when the instructions are executed by a processor (120) (e.g., the processor (120) of FIG. 1), the instructions may cause the electronic device (101) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 9.

[0142] At least some of the operations illustrated in FIG. 9 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 9.

[0143] According to one embodiment, at least some of the operations illustrated in FIG. 9 may be performed sequentially.

[0144] According to one embodiment, at least some of the operations illustrated in FIG. 9 can be performed in parallel (simultaneously).

[0145] Hereinafter, referring to FIG. 9, an operation of an electronic device (101) according to one embodiment to change the output voltage of an external device (301) and the multiplication value of a second charger (320) according to a change in the amount of charging current input to a battery (189) will be described.

[0146] In operation 910, an electronic device (101) according to an embodiment (e.g., the electronic device (101) of FIG. 1) may check a voltage level of a battery (189) (e.g., the battery (189) of FIG. 3). For example, after the electronic device (101) charges the battery (189) according to a first combination of the voltage of the initially set external device (301) and the driving ratio of the second charger (320), if the amount of change in the charging current exceeds a second threshold, the electronic device (101) may change the setting again. If the amount of change in the charging current exceeds the second threshold, the electronic device (101) may check the voltage level of the battery (189) and check which section among the sections defined in the charging profile the current voltage level of the battery (189) corresponds to.

[0147] In operation 920, the electronic device (101) according to one embodiment may determine a charging current value corresponding to the supply power (voltage, current) information of the external device (301) and the voltage level of the identified battery (189) based on a specified table. For example, if the voltage level of the current battery (189) has changed from the first section to the second section of the charging profile, any one of candidate settings pre-stored by the table (e.g., Table 1) Candidate 2-1 (9 V, 2:1) or Candidate 2-2 (20 V, 4:1) may be selected. When selecting any one of the selected candidate settings, the electronic device (101) may re-perform at least some of the operations described with reference to FIGS. 5 to 7.

[0148] In operation 930, the electronic device (101) according to one embodiment may determine, based on the determined charging current value, a third output voltage among a plurality of output voltages that the external device (301) (e.g., the external device (301) of FIG. 3) may output, and a third multiplier value among multiplier values ​​for a specified multiplier that the second charger (320) (e.g., the second charger (320) of FIG. 3) may vary.

[0149] In operation 940, the electronic device (101) according to one embodiment may control the external device (301) to cause the external device (301) to output a third output voltage. The electronic device (101) according to one embodiment may transmit information (or data) related to a power change to the external device (301). The electronic device (101) according to one embodiment may request information (or data) related to a power change from the external device (301). In the present disclosure, the electronic device (101) controlling the external device (301) may be interpreted to mean that the electronic device (101) transmits a request signal to the external device (301).

[0150] FIG. 10 is a flowchart illustrating an operation of an electronic device (101) according to one embodiment of the present invention to change the output voltage of an external device (301) and the multiplier value of a second charger (320) according to a change in the voltage level of a battery (189).

[0151] The operations illustrated in FIG. 10 may be performed by instructions stored in a memory (130) (e.g., the memory (130) of FIG. 1). For example, when the instructions are executed by a processor (120) (e.g., the processor (120) of FIG. 1), the instructions may cause the electronic device (101) (e.g., the electronic device (101) of FIG. 1) to perform the operations illustrated in FIG. 10.

[0152] At least some of the operations illustrated in FIG. 10 may be omitted. At least some of the operations mentioned with reference to other drawings in this disclosure may be additionally inserted before or after at least some of the operations illustrated in FIG. 10.

[0153] According to one embodiment, at least some of the operations illustrated in FIG. 10 may be performed sequentially.

[0154] According to one embodiment, at least some of the operations illustrated in FIG. 10 may be performed in parallel (simultaneously).

[0155] Hereinafter, with reference to FIG. 10, an operation of an electronic device (101) according to one embodiment to change the output voltage of an external device (301) and the multiplication value of a second charger (320) according to the amount of change in the voltage level of a battery (189) will be described.

[0156] In operation 1010, an electronic device (101) according to an embodiment (e.g., the electronic device (101) of FIG. 1) may check a voltage level of a battery (189) (e.g., the battery (189) of FIG. 3). For example, after the electronic device (101) charges the battery (189) according to a first combination of the voltage of the initially set external device (301) and the driving ratio of the second charger (320), if the amount of change in the voltage level of the battery (189) exceeds a third threshold, the electronic device (101) may change the setting again. If the amount of change in the voltage level of the battery (189) exceeds the third threshold, the electronic device (101) may check the voltage level of the battery (189) and check which section among the sections defined in the charging profile the current voltage level of the battery (189) corresponds to.

[0157] In operation 1020, the electronic device (101) according to one embodiment may determine a charging current value corresponding to the supply power (voltage, current) information of the external device (301) and the voltage level of the identified battery (189) based on a designated table (e.g., Table 1). For example, if the voltage level of the current battery (189) has changed from the first section to the second section of the charging profile, the electronic device may select one of the candidate settings pre-stored by the table (e.g., Table 1), candidate 2-1 (9 V, 2:1) or candidate 2-2 (20 V, 4:1). When selecting one of the selected candidate settings, the electronic device (101) may re-perform at least some of the operations described with reference to FIGS. 5 to 7.

[0158] In operation 1030, the electronic device (101) according to one embodiment may determine, based on the determined charging current value, a fourth output voltage among a plurality of output voltages that the external device (301) (e.g., the external device (301) of FIG. 3) may output, and a fourth multiplier value among multiplier values ​​for a specified multiplier that the second charger (320) (e.g., the second charger (320)) may vary.

[0159] In operation 1040, the electronic device (101) according to one embodiment controls the external device (301) so that the external device (301) can output a fourth output voltage. The electronic device (101) according to one embodiment can transmit information (or data) related to a power change to the external device (301). The electronic device (101) according to one embodiment can request information (or data) related to a power change from the external device (301). In the present disclosure, the electronic device (101) controlling the external device (301) can be interpreted to mean that the electronic device (101) transmits a request signal to the external device (301).

[0160] Fig. 11 is a charging graph illustrating a scenario in which an electronic device (101) according to one embodiment charges a battery (189) using an external device (301) that supports a PPS function. Fig. 12 is a charging graph illustrating a scenario in which an electronic device (101) according to a comparative example charges a battery (189) using an external device (301) that does not support a PPS function. Fig. 13 is a charging graph illustrating a scenario in which an electronic device (101) according to one embodiment charges a battery (189) using an external device (301) that does not support a PPS function.

[0161] In FIGS. 11 to 13, the horizontal axis may represent each section defined in the charging profile. In FIGS. 11 to 13, the vertical axis positioned on the left may represent the voltage level (Vbat) of the battery (189). In FIGS. 11 to 13, the vertical axis positioned on the right may represent the charging current (Ibat) of the battery (189).

[0162] Referring to FIG. 11, when an electronic device (101) according to one embodiment charges a battery (189) using an external device (301) that supports a PPS function, the external device (301) finely adjusts the output voltage in a range of about 3 V to about 21 V as it supports the PPS function. Accordingly, it can be seen that the electronic device (101) controls the output voltage of the external device (301) and the driving ratio of the second charger (320) to correspond to the voltage level (1110) and the charging current (1120) of the battery (189) for each section defined in the charging profile, thereby achieving the largest accumulated charging current amount (1101). The area of ​​the hatched region “1101” in FIG. 11 represents the accumulated charging current amount (1101) while charging is in progress. This means that when the electronic device (101) according to one embodiment charges the battery (189) using an external device (301) that supports the PPS function, the battery (189) can be charged most quickly.

[0163] Referring to FIG. 12, when an electronic device (101) according to a comparative example charges a battery (189) using an external device (301) that does not support a PPS function, it can be seen that the accumulated charging current amount (1201) is less than the accumulated charging current amount (1101) described in the example of FIG. 11, since the external device (301) outputs a fixed voltage regardless of the section-by-section voltage level (1210) (e.g., section-by-section voltage level (1110) of FIG. 11) and charging current (1220) of the battery (189) defined in the charging profile of the battery (189). The area of ​​the hatched region “1201” in FIG. 12 represents the accumulated charging current amount (1201) while charging is in progress. This means that when the electronic device (101) according to the comparative example charges the battery (189) using an external device (301) that does not support the PPS function, the speed at which the battery (189) is charged is slow.

[0164] Referring to FIG. 13, when an electronic device (101) according to one embodiment charges a battery (189) using an external device (301) that does not support a PPS function, the electronic device (101) may select an optimal combination among combinations of output voltages of the external device (301) and driving ratios of the second charger (320), and charge the battery (189) based on the selected combination, even if the external device (301) outputs a fixed voltage regardless of the section-by-section voltage level (1310) (e.g., section-by-section voltage level (1110) of FIG. 11) and charging current (1320) of the battery (189) defined in the charging profile of the battery (189). For example, the electronic device (101) selects an optimal combination among combinations of output voltages of the external device (301) and driving ratios of the second charger (320) whenever a specified condition is satisfied, as described with reference to FIGS. 4 to 10, and varies the output voltage of the external device (301) and the driving ratio of the second charger (320) according to the selected combination. It can be seen that the electronic device (101) according to this embodiment has a larger accumulated charging current amount (1101) than the accumulated charging current amount (1201) described in the example of FIG. 12. The area of ​​the hatched region “1301” in FIG. 13 represents the accumulated charging current amount (1301) while charging is in progress.

[0165] According to one embodiment, the electronic device (101) may have a relatively large accumulated charging current (1301) compared to the comparative example of FIG. 12 due to an increase in the charging current according to a variation in the output voltage of the external device (301) and the driving ratio of the second charger (320), as shown in 1302 of FIG. 13. This means that when the electronic device (101) according to one embodiment charges the battery (189) using an external device (301) that does not support the PPS function, the charging speed of the battery (189) becomes faster and the charging efficiency becomes higher. The example described in FIG. 13 may be a case where the external device (301) supports output voltages of about 5 V, about 9 V, about 15 V, and about 20 V. If the external device (301) supports various types of output voltages, the accumulated charging current (1301) may increase more than the example shown, thereby increasing the speed of charging the battery (189) and improving the charging efficiency.
