Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a bypass continuation of International Application No. PCT/KR2021/008343, filed on Jul. 1, 2021, in the Korean Intellectual Property Receiving Office, which is based on and claims priority to Korean Patent Application No. 10-2020-0082411, filed on Jul. 3, 2020, in the Korean Intellectual Property Office, the disclosures of which are incorporated herein by reference in their entireties. 
    
    
     BACKGROUND 
     1. Field 
     The disclosure relates to a battery charging method and an electronic device supporting same. 
     2. Description of Related Art 
     Recently, demand for batteries is growing due to the increase of demand for portable electronic devices. A battery is an energy storage device converting energy generated by chemical reaction into electric energy and using same, and a primary cell, a secondary cell, and a fuel cell belong to such a battery. Generally, a battery that, after making a reaction, does not react again and is thus not reusable even when electric energy is applied thereto again, may be referred to as a primary battery, and a battery that allows repetitive reversible reactions and is thus continuously usable may be referred to as a secondary battery. 
     In the related art, in order to charge a battery in a short time, multiple charging intervals before the battery capacity reaches a fully-charged state are configured, and different charging currents are configured for the configured charging intervals. The charging current may have a value which changes even in a single charging interval according to a constant current (CC) interval and a constant voltage (CV) interval. 
     A battery of an electronic device may be in a deteriorated state due to an external cause (e.g., temperature) or an internal cause (e.g., increase in consumed current). In the deteriorated state of the battery, the battery may reach early a time point of entering a CV interval from a CC interval in multiple charging intervals. In addition, in the deteriorated state of the battery, the battery may enter a CV interval quickly in each of the multiple charging intervals due to the impedance increase, and thus the charging current may decrease compared to a CC interval. 
     Due to the above causes, even though the battery voltage satisfies a condition for entrance into the next charging interval and the charging current is reduced enough to satisfy a condition for entrance into the next interval, the battery may fail to satisfy a condition of the state of charge (SoC) and may be thus unable to immediately enter the next charging interval. 
     SUMMARY 
     Provided are a battery charging method and an electronic device supporting same, for configuring multiple charging intervals reflecting the state of charge of a battery, based on a target current and/or a target voltage of each charging interval. 
     Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments. 
     According to an aspect of the disclosure, an electronic device includes a battery and a processor configured to, while maintaining a charging current at a first constant current, identify whether a charging voltage reaches a first target voltage, based on identifying that the charging voltage has reached the first target voltage, convert the charging current to a first charging current, identify whether the charging current reaches a first target current, and based on identifying that the charging current has reached the first target current, convert the charging current to a second constant current corresponding to the first target current. 
     The processor may be further configured to, based on identifying that the charging voltage has reached the first target voltage, convert the charging voltage to a first constant voltage corresponding to the first target voltage, and while the first constant voltage is maintained, identify whether the charging current reaches the first target current. 
     The processor may be further configured to, based on a current consumed in the electronic device, identify whether the charging current reaches the first target current. 
     The processor may be further configured to designate multiple charging intervals, based on at least one of multiple target voltages including the first target voltage and multiple target currents including the first target current. 
     The processor may be further configured to distinguish the multiple charging intervals independent of a state of charge (SoC) of the battery. 
     The multiple charging intervals may include a first charging interval and a second charging interval, and the processor may be further configured to, based on the charging current being converted to the second constant current, enter the second charging interval after the first charging interval. 
     The processor may be further configured to, based on the second charging interval being entered into from the first charging interval, convert the charging voltage to a second charging voltage while the second constant current is maintained in the second charging interval, and maintain the charging current at the second constant current while the second charging voltage is maintained. 
     A first time point from entering the second charging interval may be earlier than a second time point at which the charging current is converted from the first charging current into the second constant current. 
     The processor may be further configured to, identify whether at least one count among a charging count and a discharging count of the battery corresponds to a designated number, and based on identifying that the at least one count corresponds to the designated number, adjust at least one of the multiple target voltages and the multiple target currents for each of the multiple charging intervals. 
     The first target current may have a current lower than the first constant current. 
     According to an aspect of the disclosure, a method of charging a battery includes identifying whether a charging voltage reaches a first target voltage while maintaining a charging current at a first constant current, based on identifying that the charging voltage has reached the first target voltage, converting the charging current into a first charging current, identifying whether the charging current reaches a first target current, and based on identifying that the charging current has reached the first target current, converting the charging current from the first charging current to a second constant current corresponding to the first target current. 
     The identifying of whether the charging current reaches the first target current may include, based on identifying that the charging voltage has reached the first target voltage, converting the charging voltage to a first constant voltage corresponding to the first target voltage , and while the first constant voltage is maintained, identifying whether the charging current reaches the first target current. 
     The identifying of whether the charging current reaches the first target current may include identifying whether the charging current reaches the first target current, based on a current consumed in an electronic device. 
     The method may include designating multiple channel intervals based on at least one of multiple target voltages including a first target voltage, and multiple target currents including the first target current. 
     The designating of the multiple charging intervals may include distinguishing the multiple charging intervals independent of a SoC of the battery.

In an embodiment, the corresponding sensor (e.g., a temperature sensor) in the sensor module  176  may be included as a part of the battery protection circuit  240 , or may be disposed near the battery  189  as a separate device. 
       FIG.  3    is a diagram of an electronic device according to an embodiment. 
     Referring to  FIG.  3   , an electronic device  300  (e.g., the electronic device  101  in  FIG.  1   ) may charge a battery  330  (e.g., the battery  189  in  FIG.  1   ), based on the power supplied from the outside (e.g., a charger). In an embodiment, the battery  330  may be in a deteriorated state according to an external cause (e.g., temperature) or an internal cause (e.g., increase in consumed current). The electronic device  300  may configure multiple charging intervals, based on a target current and/or target voltage of each charging interval in multiple charging intervals configured based on the state of charge (SoC) of the battery  330 . For example, the electronic device  300  may adjust a target current for reaching a designated state of charge (e.g., a state of charge of about 30%) of one charging interval among multiple charging intervals regardless of the designated state of charge. Accordingly, the electronic device  300  may reduce delay of the charging time of the battery  330  due to impedance increase when the battery  330  is in a deteriorated state. 
     According to an embodiment, the SoC of the battery  330  may indicate an energy amount stored in the battery. The energy amount may be, for example, a ratio between a total capacity and a charge amount extractable from a cell at a particular time point. In an embodiment, the SoC of the battery  330  may be calculated by measuring at least one of the voltage, the current, the resistance, the temperature, the charging count, and the discharging count of the battery. 
     The electronic device  300  for providing the above functions may include a power management module  310 , the battery  330 , and a processor  350  with reference to  FIG.  3   . However, the element of the electronic device  300  is not limited thereto. In various embodiments, the electronic device  300  may exclude at least one of the above elements or may further include at least another element. For example, the electronic device  300  may further include a communication circuit (e.g., the communication module  190  in  FIG.  1   ). 
     According to an embodiment, the power management module  310  (e.g., the power management module  188  in  FIG.  1   ) may manage the power supplied to the electronic device  300 . In an embodiment, the power management module  310  may charge the battery  330  by using the power supplied from the outside. In an embodiment, the power management module  310  may control charging and discharging of the battery  330 . In an embodiment, the power management module  310  may supply the power supplied from the battery  330  or the outside, to an internal circuit of the electronic device  300 . In an embodiment, the power management module  310  may correspond to at least one of a PMIC and a charging circuit. 
     In an embodiment, the power management module  310  may use a charging circuit (e.g., the charging circuit  210  in  FIG.  2   ), a power regulator (e.g., the power regulator  220  in  FIG.  2   ), or a power gauge (e.g., the power gauge  230  in  FIG.  2   ) to determine battery state information (e.g., lifetime, overvoltage, low voltage, overcurrent, overcharge, overdischarge, overheat, short and/or swelling)) related to charging of the battery  189 . In an embodiment, the power management module  310  may adjust a voltage level or a current level of the power supplied from the outside or the battery  330 , to generate multiple powers having different voltages or different current levels. According to an embodiment, the power management module  310  may adjust the power of the outside or the battery  330  to have voltage or current levels suitable for respective elements included in the electronic device  300 . In an embodiment, the power management module  310  may measure usage state information for the battery  330  (e.g., the capacity, the charging/discharging count, the voltage, and/or the temperature of the battery  330 ). In an embodiment, at least some of the functions of the power management module  310  may be performed by the processor  350 . 
     According to an embodiment, the battery  330  (e.g., the battery  189  in  FIG.  1   ) may supply power to at least one element of the electronic device  300 . In an embodiment, the battery  330  may be charged by the power supplied from the power management module  310 . In an embodiment, the battery  330  may be discharged by the consumed current (e.g., a current for execution of an application) of the electronic device  300 . In an embodiment, the battery  330  may correspond to a rechargeable second battery. 
     According to an embodiment, the processor  350  (e.g., the processor  120  in  FIG.  1   ) may adjust the power supplied to the battery  330  via the power management module  310 . In an embodiment, the processor  350  may configure multiple charging intervals up to the capacity of the battery  330  in a fully-charged state in order to charge the battery  330 . In addition, the processor  350  may configure different charging currents for the respective configured charging intervals. For example, the processor  350  may configure multiple charging intervals including a first charging interval having a first target current configured up to a 30% state of charge of the battery  330 , a second charging interval having a second target current configured up to a 65% state of charge of the battery  330 , and a third charging interval having a third target current configured up to a 100% state of charge of the battery  330 . 
     According to an embodiment, the processor  350  may configure the configured multiple charging intervals to correspond to the deteriorated state of the battery  330 . For example, the processor  350  may configure multiple charging intervals by adjusting a target current in a constant current (CC) interval and a constant voltage (CV) interval included in each of the configured charging interval. 
     According to an embodiment, the processor  350  and/or the power management module  310  may calculate the deteriorated state of the battery  330 , based on at least one of the current, the voltage, the temperature, the resistance, the charging count, and the discharging count of the battery  330 . 
     According to an embodiment, the processor  350  may maintain a charging current at a first constant current (e.g., 7500 mA) in one charging interval (e.g., the first charging interval) among multiple charging intervals configured based on a target current and/or a target voltage. In an embodiment, the processor  350  may identify whether, in the one charging interval, a charging voltage reaches a first target voltage (e.g., 4.13 V) from a first charging voltage (e.g., 4 V) due to the charging current maintained at the first constant current. In an embodiment, when the charging voltage has reached the first target voltage from the first charging voltage, the processor  350  may convert the charging current into a first charging current changed (e.g., changed by a downward inclination) from the first constant current. In an embodiment, the processor  350  may identify whether the charging current reaches a first target current (e.g., 5400 mA) adjusted from the first charging current. In an embodiment, when the charging current has reached the first target current adjusted from the first charging current, the processor  350  may convert the charging current from the first charging current into a second constant current (e.g., 5400 mA) corresponding to the first target current. In an embodiment, the processor  350  may enter a different charging interval (e.g., the second charging interval after the first charging interval) from the one charging interval among the configured multiple charging intervals, based on the charging current converted into the second constant current. 
     According to an embodiment, the processor  350  may identify, in one charging interval (e.g., the first charging interval) among multiple charging intervals configured based on a target current and/or a target voltage, whether a charging current reaches a corresponding target current of the one charging interval, based on the system current consumed in the electronic device  300 . For example, in case that an application is executed in the electronic device  300 , the processor  350  may, based on whether a sum of the current (e.g., the consumed current of a system) consumed by execution of the application and a charging current (e.g., a charging current supplied to the battery  330 ) of the one charging interval corresponds to a corresponding target current, identify whether the charging current reaches the corresponding target current. 
     According to an embodiment, the processor  350  may adjust a corresponding target voltage and/or a corresponding target current for each charging interval among the configured multiple charging intervals, based on whether the charging count and/or the discharging count of the battery  330  corresponds to a designated number. For example, whether the charging count and/or the discharging count of the battery  330  is equal to or greater than a designated first number (e.g., 300 times), the processor  350  may adjust a corresponding target voltage and/or a corresponding target current for each of the charging intervals, based on a first configuration. The first configuration may be a configuration for adjusting a corresponding target voltage and/or a corresponding target current of each of the first charging interval to the third charging interval. In an embodiment, the processor  350  may gradually lower a corresponding target voltage and/or a corresponding target current for each of the charging intervals as the charging count and/or the discharging count of the battery  330  gets larger. 
     According to various embodiments, at least some functions of the processor  350  described above may be performed by the power management module  310 . For example, the power management module  310  may convert a charging current into a charging current changed from a constant current and/or convert a charging voltage into a constant current from a changed charging voltage in at least one charging interval (e.g., the first charging interval) among multiple charging intervals configured based on a target current and/or a target voltage. 
       FIG.  4    is a flowchart illustrating a method  400  for charging a battery in an electronic device according to an embodiment. 
     Referring to  FIG.  4   , the electronic device  300  (e.g., the electronic device  300  in  FIG.  3   ) may perform operation  410  to operation  490  to adjust a target current in a CC interval and a CV interval included in each of the configured multiple charging intervals according to a deteriorated state of a battery (e.g., the battery  330  in  FIG.  3   ) so as to configure multiple charging intervals. 
     Referring to operation  410 , the electronic device  300  may charge the battery  330 , based on the power supplied from the outside. In operation  410 , in the electronic device  300 , an external cause (e.g., impedance increase) may be applied in a process of charging the battery  330  due to a deteriorated state. 
     Referring to operation  430 , the electronic device  300  may maintain a charging current at a first constant current (e.g., 7500 mA) in one charging interval (e.g., the first charging interval) among multiple charging intervals configured based on a target current and/or a target voltage, and then identify whether a charging voltage reaches a first target voltage (e.g., 4.13 V) adjusted from a first charging voltage (e.g., 4 V). For example, in operation  430 , in case that the charging voltage reaches, in the one charging interval, the first target voltage (e.g., 4.13 V) adjusted from the first charging voltage (e.g., 4 V) due to the charging current maintained at the first constant current, the electronic device  300  may perform operation  450 . As another example, in case that the charging voltage does not reach, in the one charging interval, the first target voltage (e.g., 4.13 V) adjusted from the first charging voltage (e.g., 4 V) due to the charging current maintained at the first constant current, the electronic device  300  may repeatedly perform operation  430 . 
     Referring to operation  450 , in case that the charging voltage has reached, in the one charging interval, the first target voltage (e.g., 4.13 V) adjusted from the first charging voltage (e.g., 4 V) due to the charging current maintained at the first constant current, the electronic device  300  may convert the charging current into a first charging current changed (e.g., changed by a downward inclination) from the first constant current. The first charging current changed from the first constant current may be a first charging current adjusted by impedance increase in the one charging interval. 
     Referring to operation  470 , the electronic device  300  may identify whether the charging current reaches a first target current (e.g., 5400 mA) adjusted from the first charging current. The electronic device  300  may, for example, operation  470 , identify whether the charging current reaches the first target current adjusted from the first charging current until a time point at which the charging voltage is maintained at the adjusted first target voltage. For example, in case that the charging current has reached the first target current adjusted from the first charging current, the electronic device  300  may perform operation  490 . As another example, in case that the charging current does not reach the first target current adjusted from the first charging current, the electronic device  300  may repeatedly perform operation  470 . 
     Referring to operation  490 , in case that the charging current has reached the first target current adjusted from the first charging current, the electronic device  300  may convert the charging current into a second constant current (e.g., 5400 mA). The second constant current may be a current corresponding to the first target current. The electronic device  300  may, for example, after operation  490 , maintain the second constant current to enter a different charging interval after the one charging interval from the one charging interval. 
       FIG.  5    illustrates a graph showing charging intervals of a battery, configured based on a charging current and a charging voltage in an electronic device according to an embodiment. 
     Referring to  FIG.  5   , an electronic device (e.g., the electronic device  300  in  FIG.  3   ) may configure a charging interval for the power introduced from the outside to a battery (e.g., the battery  330  in  FIG.  3   ), based on a charging current  510  and/or a charging voltage  530 . The charging current  510  may, for example, reach an adjusted target current early in a charging interval configured based on the charging current  510  and/or the charging voltage  530  unlike an initial charging current  515  in multiple charging intervals (which may be referred to as initial charging intervals) (e.g., S 1 ′-S 3 ′) configured based on the state of charge of the battery  330 . 
     In a configured first charging interval S 1 , the electronic device  300  may maintain the charging current  510  at a first constant current (7500 mA). In the configured first charging interval S 1 , the electronic device  300  may maintain the charging current  510  at a first constant current (7500 mA) until, for example, a time point (a time point before t1) at which the charging voltage  530  reaches a first target voltage V 1  from a first charging voltage (e.g., 4 V). In an embodiment, the electronic device  300  may configure, as a first CC interval CC 1 , the interval for which the charging current  510  is maintained at the first constant current (7500 mA). 
     In the configured first charging interval S 1 , in case that the charging voltage  530  has reached the first target voltage V 1 , the electronic device  300  may convert the charging current  510  into a first charging current changed from the first constant current (7500 mA). In the configured first charging interval S 1 , the electronic device  300  may maintain the charging current  510  at the first charging current until, for example, a time point t1 at which the charging current  510  reaches a first target current C 1  from the first charging current. The first charging current may be changed at a downward inclination before entering a second charging interval S 2 . In the configured first charging interval S 1 , the electronic device  300  may maintain the charging voltage  530  at a first constant voltage (e.g., 4.13 V) corresponding to the first target voltage until the time point t1 at which the charging current  510  reaches the first target current C 1  from the first charging current. In an embodiment, the electronic device  300  may configure, as a first CV interval CV 1 , the interval for which the charging current  510  is maintained at the first charging current. 
     In a configured second charging interval S 2 , the electronic device  300  may maintain the charging current  510  having reached the first target current C 1  at a second constant current (5400 mA). In the configured second charging interval S 2 , the electronic device  300  may, for example, maintain the charging voltage  530  having reached the first target voltage V 1  at a second charging voltage so as to maintain the charging current  510  at the second constant current (5400 mA) until a time point (a time point before T 2 ) at which the charging voltage  530  reaches a second target voltage V 2  from the second charging voltage (e.g., 4.13 V). In an embodiment, the electronic device  300  may configure, as a second CC interval CC 2 , the interval for which the charging current  510  is maintained at the second constant current (5400 mA). 
     In the configured second charging interval S 2 , in case that the charging voltage  530  has reached the second target voltage V 2 , the electronic device  300  may convert the charging current  510  into a second charging current changed from the second constant current. In the configured second charging interval S 2 , the electronic device  300  may maintain the charging current  510  at the second charging current until, for example, a time point t2 at which the charging current  510  reaches a second target current C 2  from the second charging current. The second charging current may be changed at a downward inclination before entering a third charging interval S 3 . In the configured second charging interval S 2 , the electronic device  300  may maintain the charging voltage  530  at a second constant voltage (e.g., 4.3 V) corresponding to the second target voltage until a time point t2 at which the charging current  510  reaches the second target current C 2  from the second charging current. In an embodiment, the electronic device  300  may configure, as a second CV interval CV 2 , the interval for which the charging current  510  is maintained at the second charging current. 
     In a configured third charging interval S 3 , the electronic device  300  may maintain the charging current  510  having reached the second target current C 2  at a third constant current (3800 mA). In the configured third charging interval S 3 , the electronic device  300  may, for example, maintain the charging voltage  530  having reached the second target voltage V 2  at a third charging voltage so as to maintain the charging current  510  at the third constant current (3800 mA) until a time point (a time point before T 3 ) at which the charging voltage  530  reaches a third target voltage V 3  from the third charging voltage (e.g., 4.13 V). In an embodiment, the electronic device  300  may configure, as a third CC interval CC 3 , the interval for which the charging current  510  is maintained at the third constant current (3800 mA). 
     In the configured third charging interval S 3 , in case that the charging voltage  530  has reached the third target voltage V 3 , the electronic device  300  may convert the charging current  510  into a third charging current changed from the third constant current. In the configured third charging interval S 2 , the electronic device  300  may maintain the charging current  510  at the third charging current until, for example, a time point t3 at which the charging current  510  reaches a third target current C 3  from the third charging current. The third charging current may be changed at a downward inclination before the state of charge of the battery  330  reaches a fully-charged state. In the configured third charging interval S 3 , the electronic device  300  may maintain the charging voltage  530  at a third constant voltage (e.g., 4.35 V) corresponding to the third target voltage until the time point t3 at which the charging current  510  reaches the third target current C 3  from the third charging current. In an embodiment, the electronic device  300  may configure, as a third CV interval CV 3 , the interval for which the charging current  510  is maintained at the third charging current. 
     According to an embodiment, the electronic device  300  may advance a time point of charging the battery  330  in multiple charging intervals S 1 -S 3  configured based on the charging current  510  and/or the charging voltage  530 , compared to a time point of charging the battery  330  in multiple charging intervals S 1 ′-S 3 ′ configured based on the state of charge of the battery  330 , thereby shortening the charging time of the battery  330  by a designated interval E according to the deteriorated state of the battery  330 . 
       FIG.  6    is a flowchart illustrating a method  600  for charging a battery in an electronic device according to an embodiment. 
     Referring to  FIG.  6   , the electronic device  300  according to an embodiment may perform operation  610  to operation  680  to adjust a target current in a CC interval and a CV interval included in each of the configured multiple charging intervals according to a deteriorated state of a battery (e.g., the battery  330  in  FIG.  3   ) so as to configure multiple charging intervals. 
     Referring to operation  610 , in the electronic device  300 , power may be supplied to the battery  330  from the outside via a power management module (e.g., the power management module  310  in  FIG.  3   ). In operation  610 , in the electronic device  300 , an external cause (e.g., impedance increase) may be applied in a process of charging the battery  330  due to a deteriorated state. 
     Referring to operation  620 , in case that power is supplied to the battery  330  from the outside via a power management module (e.g., the power management module  310  in  FIG.  3   ), the electronic device  300  may configure a charging interval for supplying power to the battery  330 , based on the state of charge of the battery  330 . For example, in case that the state of charge of the battery  330  is 20%, the electronic device  300  may charge the battery  330  in a first charging interval (e.g., the first charging interval S 1  in  FIG.  5   ) among multiple charging intervals configured based on a target current and/or a target voltage. 
     Referring to operation  630 , the electronic device  300  may maintain a charging current at a designated constant current (e.g., 7500 mA) in one charging interval (e.g., the first charging interval) among the configured multiple charging intervals, so as to identify whether a charging voltage reaches a target voltage (e.g., 4.13 V) adjusted from a designated charging voltage (e.g., 4 V). For example, in operation  630 , in case that the charging voltage reaches, in the one charging interval, the target voltage (e.g., 4.13 V) adjusted from the designated charging voltage (e.g., 4 V) due to the charging current maintained at the designated constant current, the electronic device  300  may perform operation  640 . As another example, in case that the charging voltage does not reach, in the one charging interval, the target voltage (e.g., 4.13 V) adjusted from the designated charging voltage (e.g., 4 V) due to the charging current maintained at the designated constant current, the electronic device  300  may repeatedly perform operation  630 . 
     Referring to operation  640 , in case that the charging voltage has reached, in the one charging interval, the target voltage (e.g., 4.13 V) adjusted from the designated charging voltage (e.g., 4 V) due to the charging current maintained at the designated constant current, the electronic device  300  may convert the charging current into a charging current changed (e.g., changed by a downward inclination) from the designated constant current. The charging current changed from the designated constant current may be a charging current adjusted by impedance increase in the one charging interval. 
     Referring to operation  650 , the electronic device  300  may identify, based on a system current, whether the changing charging current reaches a target current (e.g., 5400 mA). The electronic device  300  may, for example, operation  650 , identify whether a charging current obtained by adding the consumed current (e.g., a current for execution of an application) of the electronic device  300  reaches the target current adjusted from the designated charging current until a time point at which the charging voltage is maintained at the adjusted target voltage. For example, in case that charging current obtained by adding the consumed current has reached the target current adjusted from the designated charging current, the electronic device  300  may perform operation  660 . As another example, in case that charging current obtained by adding the consumed current does not reach the target current adjusted from the designated charging current, the electronic device  300  may repeatedly perform operation  650 . 
     Referring to operation  660 , in case that charging current obtained by adding the consumed current has reached the target current adjusted from the designated charging current, the electronic device  300  may identify whether a corresponding charging interval is the last charging interval (e.g., the third charging interval S 3  in  FIG.  5   ). For example, in case that the corresponding charging interval is the last charging interval (e.g., the third charging interval S 3  in  FIG.  5   ) the electronic device  300  may perform operation  670 . As another example, in case that the corresponding charging interval is not the last charging interval (e.g., the third charging interval S 3  in  FIG.  5   ), the electronic device  300  may perform operation  680 . 
     Referring to operation  670 , in case that the corresponding charging interval is the last charging interval, the electronic device  300  may maintain the charging current at a charging current having reached the adjusted target current until the SoC of the battery  330  reaches a fully-charged state. 
     Referring to operation  680 , in case that the corresponding charging interval is not the last charging interval, the electronic device  300  may enter the next charging interval (e.g., the second charging interval S 2  in  FIG.  5   ) after the corresponding charging interval. After operation  680 , the electronic device  300  may repeatedly perform operation  630  to operation  660  until a condition to perform operation  670  is satisfied. 
       FIG.  7    is a flowchart illustrating a method  700  for charging a battery in an electronic device according to an embodiment. 
     According to an embodiment, the electronic device  300  (e.g., the electronic device  300  in  FIG.  3   ) may perform operation  720  to operation  725  to adjust a corresponding target voltage and/or a corresponding target current for each charging interval among the configured multiple charging intervals, based on whether the charging count and/or discharging count of the battery  330  (e.g., the battery  330  in  FIG.  3   ) corresponds to a designated number. In an embodiment, the electronic device  300  may perform operation  720  to operation  725  in operation  410  and operation  430  in  FIG.  4   . 
     Referring to operation  720 , the electronic device  300  may identify whether the charging count and/or the discharging count of the battery  330  is less than a designated first number (e.g., 300 times). For example, in case that the charging count and/or the discharging count of the battery  330  is less than the designated first number, the electronic device  300   may perform operation  430  in  FIG.  4   . As another example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated first number, the electronic device  300  may perform operation  721 . 
     Referring to operation  721 , the electronic device  300  may identify whether the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated first number and is less than a designated second number (e.g., 400 times). For example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated first number and is less than the designated second number, the electronic device  300  may perform operation  722 . As another example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated second number, the electronic device  300  may perform operation  723 . 
     Referring to operation  722 , in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated first number and is less than the designated second number, the electronic device  300  may change a charging voltage, a target voltage, a charging current, and a target current to correspond to a first configuration in at least one charging interval among multiple charging intervals configured based on a target current and/or a target voltage. The first configuration may be, for example, a configuration for adjusting the charging voltage, the target voltage, the charging current, and the target current of at least one interval among a first charging interval to a third charging interval (e.g., the first charging interval S 1  to the third charging interval S 3  in  FIG.  5   ). 
     Referring to operation  723 , the electronic device  300  may identify whether the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated second number and is less than a designated third number (e.g., 700 times). For example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated second count and is less than the designated third number, the electronic device  300  may perform operation  724 . As another example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated third number, the electronic device  300  may perform operation  725 . 
     Referring to operation  724 , in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated second number and is less than the designated third number, the electronic device  300  may change a charging voltage, a target voltage, a charging current, and a target current to correspond to a second configuration in at least one charging interval among multiple charging intervals configured based on a target current and/or a target voltage. The second configuration may be, for example, a configuration for adjusting the charging voltage, the target voltage, the charging current, and the target current of at least one interval among the first charging interval to the third charging interval (e.g., the first charging interval S 1  to the third charging interval S 3  in  FIG.  5   ) to be a configuration lower than the first configuration. 
     Referring to operation  725 , in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated third number, the electronic device  300  may change a charging voltage, a target voltage, a charging current, and a target current to correspond to the n-th configuration in at least one charging interval among multiple charging intervals configured based on a target current and/or a target voltage. The n-th configuration may be, for example, a configuration for adjusting the charging voltage, the target voltage, the charging current, and the target current of at least one interval among the first charging interval to the third charging interval (e.g., the first charging interval S 1  to the third charging interval S 3  in  FIG.  5   ) to be a configuration lower than the second configuration. 
     In an embodiment, the electronic device  300  may gradually lower a charging voltage, a target voltage, a charging current, and a target current for each of the configured multiple charging intervals as the charging count and/or the discharging count of the battery  330  gets larger. For example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated first number and is less than the designated second number, the electronic device  300  may adjust the first target voltage to 4120 mV and adjust the first target current to 5300 mA in the first charging interval S 1 , may adjust the second target voltage to 4290 mV and adjust the second target current to 3700 mA in the second charging interval S 2 , and may adjust the third target voltage to 4340 mV in the third charging interval S 3 . As another example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated second number and is less than the designated third number, the electronic device  300  may adjust the first target voltage to 4110 mV and adjust the first target current to 5200 mA in the first charging interval S 1 , may adjust the second target voltage to 4280 mV and adjust the second target current to 3600 mA in the second charging interval S 2 , and may adjust the third target voltage to 4330 mV in the third charging interval S 3 . In an embodiment, the electronic device  300  may adjust a charging voltage and a charging current to correspond to a corresponding target voltage and a corresponding target current adjusted based on the charging count and/or the discharging count of the battery  330  described above. 
       FIG.  8    illustrates a graph showing multiple different target voltages and/or multiple different target currents configured for multiple charging intervals, based on a charging count and/or a discharging count of a battery in an electronic device according to an embodiment. 
     Referring to  FIG.  8   , an electronic device (e.g., the electronic device  300  in  FIG.  3   ) may adjust a corresponding target voltage and/or a corresponding target current for each charging interval among the configured multiple charging intervals, based on whether the charging count and/or the discharging count of the battery  330  corresponds to a designated number. For example, the processor  350  may gradually reduce a corresponding target voltage V 1 , V 2 , or V 3  and/or a corresponding target current C 1 , C 2 , or C 3  for each of the charging intervals as the charging count and/or the discharging count of the battery  330  gets larger. 
     In the configured first charging interval S 1  to third charging interval S 3 , the electronic device  300  may configure the target currents C 1 , C 2 , and C 3  of a first charging current  811  for the configured first charging interval S 1  to third charging interval S 3 , respectively. For example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than a designated first number (e.g., 300 times), the electronic device  300  may maintain the target currents C 1 , C 2 , and C 3  of the first charging current  811  to be in an initial state for the configured first charging interval S 1  to third charging interval S 3 . In the configured first charging interval S 1  to third charging interval S 3 , the electronic device  300  may configure a first charging voltage  831  corresponding to the first charging current  811 . For example, in case that the charging count and/or the discharging count of the battery  330  is less than the designated first number (e.g., 300 times), the electronic device  300  may maintain the target voltages V 1 , V 2 , and V 3  of the first charging voltage  831  to be in an initial state for the configured first charging interval S 1  to third charging interval S 3 . 
     In the configured first charging interval S 1  to third charging interval S 3 , the electronic device  300  may configure the target currents C 1 , C 2 , and C 3  of a second charging current  813  for the configured first charging interval S 1  to third charging interval S 3 , respectively. For example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated first number and is less than a designated second number (e.g., 400 times), the electronic device  300  may convert the target currents C 1 , C 2 , and C 3  of the second charging current  813  into target currents lower than the target currents of the initial state for the configured first charging interval S 1  to third charging interval S 3 . In the configured first charging interval S 1  to third charging interval S 3 , the electronic device  300  may configure a second charging voltage  833  corresponding to the second charging current  813 . For example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated first number and is less than the designated second number, the electronic device  300  may convert the target voltages V 1 , V 2 , and V 3  of the second charging voltage  833  into target voltages lower than the target voltages of the initial state for the configured first charging interval S 1  to third charging interval S 3 . 
     In the configured first charging interval S 1  to third charging interval S 3 , the electronic device  300  may configure the target currents C 1 , C 2 , and C 3  of a third charging current (e.g., charging current  515 ) for the configured first charging interval S 1  to third charging interval S 3 , respectively. For example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated second number and is less than a designated third number (e.g., 700 times), the electronic device  300  may convert the target currents C 1 , C 2 , and C 3  of the third charging current  815  into target currents lower than a second target current for the configured first charging interval S 1  to third charging interval S 3 . In the configured first charging interval S 1  to third charging interval S 3 , the electronic device  300  may configure a third charging voltage  835  corresponding to the third charging current. For example, in case that the charging count and/or the discharging count of the battery  330  is equal to or greater than the designated second number and is less than the designated third number, the electronic device  300  may convert the target voltages V 1 , V 2 , and V 3  of the third charging voltage  835  into target voltages lower than a second target voltage for the configured first charging interval S 1  to third charging interval S 3 . 
     According to an embodiment, the electronic device  300  may gradually reduce a corresponding target voltage V 1 , V 2 , or V 3  and/or a corresponding target current C 1 , C 2 , or C 3  for each of the charging intervals S 1 , S 2 , or S 3  as the charging count and/or the discharging count of the battery  330  gets larger, so that the charging time of the battery  330  may be gradually reduced. For example, in case that the charging count and/or the discharging count is less than the designated first number (e.g., 300 times), the electronic device  300  may complete charging of the battery  330  at a third time point t3, based on a target voltage V 1 , V 2 , or V 3  of an initial state and/or a target current C 1 , C 2 , or C 3  of an initial state. As another example, in case that the charging count and/or the discharging count is equal to or greater than the designated first number and is less than the designated second number (e.g., 400 times), the electronic device  300  may complete charging of the battery  330  at a fourth time point t4 earlier than the third time point t3, based on a target voltage V 1 , V 2 , or V 3  and/or a target current C 1 , C 2 , or C 3  lower than a charging voltage V 1 , V 2 , or V 3  of an initial state and/or a charging current C 1 , C 2 , or C 3  of an initial state.

     According to various embodiments, the processor  350  may be configured to, when the second charging interval S 2  is entered into from the first charging interval S 1 , convert the charging voltage  530  into a second charging voltage changed from the first constant voltage while the second constant current is maintained in the second charging interval S 2 , and maintain the charging current  510  at the second constant current while the second charging voltage is maintained. 
     According to various embodiments, a time point (e.g., the first time point t1 in  FIG.  5   ) of entrance into the second charging interval S 2  from the first charging interval S 1  may be earlier than a time point (e.g., the different first time point t1′ in  FIG.  5   ) at which a charging current (e.g., the charging current  515  in  FIG.  5   ) is converted from a first charging current into a second constant current, according to a state of charge of the battery  330  in different multiple charging intervals (e.g., the different multiple charging intervals S1′, S2′, and S3′ in  FIG.  5   ) distinguished according to the state of charge of the battery  330 .
