[0077] Figure 3A is a flowchart illustrating an example operation of setting charging / discharging information by the electronic device 201 according to various implementations of the present disclosure.

[0078] In operation 301, the electronic device 201 may set the charge / discharge information of the battery 296. The battery charge / discharge information may include at least one of a charge voltage, a charge current, a charge time, and a power-off voltage. The electronic device 201 may set the charge / discharge information using the configuration information of the battery obtained from the user. The electronic device 201 may set the charge / discharge information of the battery 296, for example, using the usage information of the battery 296. When the battery charge / discharge mode is a full charge / discharge mode, the electronic device 201 may set the charge voltage to a full charge voltage or set the power-off voltage to a full discharge voltage.

[0079] When the battery charge / discharge mode is a user configuration mode, the electronic device 201 may obtain battery configuration information from the user via the input device 250. The battery device 201 may use the battery configuration information obtained from the user to set the charge / discharge information of the battery. The battery configuration information may include data from at least one item selected from the charging voltage, charging current, charging time, and power shutoff voltage. For example, when a charging voltage of 4.2V is input from the user, the electronic device 201 may set the charging voltage of the battery 296 to 4.2V. For example, when a power shutoff voltage of 3.7V is input from the user, the electronic device 201 may set the power shutoff voltage of the battery 296 to 3.7V. For example, when a charging current of 1.8A is input from the user, the electronic device 201 may set the charging current of the battery 296 to 1.8A.

[0080] When the battery charge / discharge mode is set to the automatic configuration mode, the electronic device 201 can use the usage information of the battery 296 to set the charge / discharge information of the battery 296. For example, when the user uses a fully charged battery 296 of 4.3V every time at lunch time, the electronic device 201 can detect the charge / discharge state of the battery 296 and recognize the way of using a battery voltage of about 4.1V every time at lunch time. In other words, the electronic device 201 can infer that the user needs a battery voltage of 4.1V at lunch time, rather than a fully charged voltage of 4.3V. The electronic device 201 can use the usage information to set the charging voltage of the battery 296 to 4.1 to 4.15V. For another example, when the user uses a battery voltage of about 3.9V on weekdays and a battery voltage of about 4.1V on weekends, the electronic device 201 can use the usage information to set the charging voltage of the battery 296 to 3.9 to 3.95V on weekdays and to 4.1V to 4.15V on weekends.

[0081] In operation 303, the electronic device 201 may charge or discharge the battery based on the set battery charge / discharge information. When the battery charge / discharge mode is a full charge / discharge mode, the electronic device 201 may charge the battery 296 to a full charge voltage and discharge the battery 296 to a full discharge voltage. For example, when the charge voltage is set to a full charge voltage of 4.3V, the electronic device 201 may charge the battery 296 to 4.3V. When the battery charge / discharge mode is a user configuration mode, the electronic device 201 may charge or discharge the battery 296 based on the charge / discharge information obtained from the user. For example, when the user sets the charge voltage to 4.1V, the electronic device 201 may charge the battery 296 only to 4.1V. For another example, when the user sets the power off voltage to 3.7V, the electronic device 201 may discharge the battery 296 only to 3.7V. When the battery charge / discharge mode is the automatic configuration mode, the electronic device 201 can charge or discharge the battery 296 based on the battery charge / discharge information configured using the usage information of the battery 296. For another example, assume that the full charge voltage of the battery is 4.3V. When the user uses a discharge mode that consumes 1000mAh of battery capacity, the electronic device 201 can set the charge voltage to a voltage lower than the full charge voltage of 4.3V (for example, 4.15V, see Table 1). The electronic device 201 can charge the battery 296 with the configured charge voltage.

[0082] Figure 3B is a graph showing the number of battery charge / discharge cycles according to changes in battery charge voltage according to various embodiments of the present disclosure.

[0083] refer to Figure 3B The picture <310> , when the electronic device 201 is used under the same conditions, the battery capacity or the number of battery charge / discharge cycles of the battery may be different depending on the charging level of the battery voltage. For example, as shown in Table 1 below, when it is assumed that the battery voltage is charged to 4.3V with a charging current of 2 amperes each time, the battery 296 may have a battery capacity of 1500mAh and may be charged up to 300 times. In addition, when it is assumed that the battery voltage is charged to 4.2V with a charging current of 2 amperes each time, the battery 296 may have a battery capacity of 1300mAh and may be charged up to 400 times. The larger the capacitance capacity, the more available time the battery 296 has. The numerical values ​​shown in Table 1 below are arbitrarily set values ​​to help clearly understand the present disclosure, but the actual values ​​may be different.

[0084] [Table 1]

[0085] Battery voltage Battery capacity Number of battery charge / discharge cycles 4.3V 1500mAh 300 times 4.25V 1400mAh 350 times 4.2V 1300mAh 400 times 4.15V 1200mAh 450 times

[0086] That is, referring to Table 1 above, it can be seen that under the same conditions, the higher the voltage at which the battery 296 is charged, the greater the battery capacity. On the other hand, it can be seen that the higher the voltage at which the battery 296 is charged, the smaller the number of battery charge / discharge cycles. This is because the charging voltage of the battery 296 is set to be higher, and the oxidation-reduction reaction occurs more violently in the battery, so the deterioration phenomenon of the battery becomes more serious. Therefore, the extension of the battery life is at the expense of reducing the capacity, and vice versa.

[0087] refer to Figure 3B The picture <320> , the charging time of the battery 296 or the number of charge / discharge cycles of the battery 296 may be different depending on the charging current flowing into the battery 296. For example, as shown in Table 2 below, when it is assumed that the battery voltage is charged to 4.3V with a charging current of 2 amperes each time, the battery 296 can be charged up to 300 times and requires two hours to charge. When it is assumed that the battery voltage is charged to 4.3V with a charging current of 2.3 amperes each time, the battery 296 can be charged up to 200 times and requires 1.6 hours to charge. When it is assumed that the battery voltage is charged to 4.2V with a charging current of 2 amperes each time, the battery 296 can be charged up to 400 times and requires 1.6 hours to charge. When it is assumed that the battery voltage is charged to 4.2V with a charging current of 2.3 amperes each time, the battery 296 can be charged up to 300 times and requires 1.2 hours to charge. The numerical values ​​shown in Table 2 below are arbitrarily set values ​​to help clearly understand the present disclosure, and the actual values ​​may be different. Therefore, the table does not limit the attached claims in any way.

[0088] [Table 2]

[0089]

[0090] In other words, referring to Table 2 above, when it is assumed that the battery is charged to the same voltage, it can be seen that the greater the charging current of the battery 296, the smaller the number of charge / discharge cycles of the battery 296. In addition, it can be seen that the greater the charging current of the battery 296, the smaller the time required to charge the battery 296.

[0091] According to various embodiments of the present disclosure, the electronic device 201 may store the content of the configuration information described in the above table in the non-transitory memory 230. For example, the electronic device 201 may store the battery capacity, the number of battery charge / discharge cycles, the battery charge / discharge time, etc. in the memory 230.

[0092] According to various embodiments of the present disclosure, the electronic device 201 can identify the number of charge / discharge cycles of the battery 296 based on the charging time or discharging time of the battery 296. For example, if it takes 2 hours to charge the battery 296 from the power-off voltage to the charging voltage, the electronic device 201 can calculate the number of times the battery 296 is charged (charged for a predetermined time (e.g., 1 hour and 30 minutes) or longer) as one. In addition, if it takes 5 hours to discharge the battery 296 from the charging voltage to the power-off voltage, the electronic device 201 can calculate the number of times the battery 296 is discharged (discharged for a predetermined time (e.g., 4 hours and 30 minutes) or longer) as one.

[0093] According to various embodiments, the number of charge / discharge cycles of the battery can be checked by the battery voltage change state of the battery 296. For example, the increase in the battery voltage can be checked. When the increase in voltage is greater than or equal to a predetermined amount (e.g., 0.6V voltage), the number of times the battery is charged can be counted as one. In addition, the number of times the battery is discharged can be checked by the battery voltage decrease.

[0094] According to various implementations of the present disclosure, the electronic device 201 may change the configured charging voltage based on the number of times of charging and discharging checked. For example, a battery that can be charged and discharged about 200 times may have the following characteristics: charging current 2.3A and battery charging voltage 4.3V. Therefore, the electronic device 201 may check the number of times the battery is charged and discharged, and calculate the battery charging / discharging information of the user, and then may reduce the charging current to 2A and change the charging voltage of the battery to 4.25V.

[0095] Figure 4A and 4B is a graph showing battery voltage 410 changing over time according to various embodiments of the present disclosure.

[0096] refer to Figure 4A , the electronic device 201 can set a charging voltage 420. The charging voltage 420 is a threshold voltage value that can be charged into the battery, and the electronic device 201 can charge the battery to a predetermined charging voltage 420. The electronic device 201 can set the charging voltage 420 to a full charging voltage 440. When the charging voltage of the battery 296 is set to the full charging voltage 440, the electronic device 201 can charge the battery 296 to a predetermined charging voltage (full charging voltage 440). When the battery 296 is charged to the full charging voltage 440, the display 260 can display a 100% battery status. For example, when the charging voltage 420 of the electronic device 201 is set to a full charging voltage 440 of 4.3V, the electronic device 201 can charge the battery voltage 410 to 4.3V and display a 100% battery status on the display 260.

[0097] According to various embodiments of the present disclosure, the electronic device 201 can use the battery configuration information and usage information of the battery 296 to set the charging voltage 420. The electronic device 201 can charge the battery 296 to the configured charging voltage 420. When the battery 296 is charged to the charging voltage 420, the display 260 can display a 100% battery status. For example, the electronic device 201 obtains 4.1V battery setting information from the user, sets the charging voltage 420 to 4.1V, and the electronic device 201 can charge the battery voltage 410 to 4.1V, and display the battery status on the display 260 with a corresponding ratio (the ratio when the fully charged voltage is regarded as 100%), or display the charging voltage 420 at 100%. Depending on the state of the charging voltage, battery color information or different icons can be added for display on the display.

[0098] According to various embodiments of the present disclosure, the electronic device 201 may set a power-off voltage 430. Figure 4A In the example of , the power-off voltage 430 is 3.7 volts. The power-off voltage 430 is a threshold voltage to which the battery can be discharged. When the electronic device 201 discharges the battery 296 to the power-off voltage 430, the power supply of the electronic device can be terminated.

[0099] For example, the power shutoff voltage 430 of the battery 296 may be set to 3.7V. The electronic device 201 may set the power shutoff voltage 430 to a full discharge voltage 450. When the power shutoff voltage 430 of the battery 296 is set to the full discharge voltage 450, the electronic device 201 may discharge the battery 296 to the configured power shutoff voltage (full discharge voltage 450). When the battery 296 is discharged to the full discharge voltage 450, the display 260 may display a 0% battery status. For example, when the power shutoff voltage 430 of the electronic device 201 is set to a full discharge voltage 450 of 3.5V, after the battery voltage 410 is consumed to 3.5V, the electronic device 201 may display a 0% battery status on the display 260.

[0100] According to various embodiments of the present disclosure, the electronic device 201 can use the battery configuration information and usage information of the battery 296 to set the power-off voltage 430. The electronic device 201 can discharge the battery 296 to the configured power-off voltage 430. When the battery 296 is discharged to the power-off voltage 430, the display 260 can display the battery status as 0%. For example, the electronic device 201 can obtain battery setting information of 3.7V from the user, set the power-off voltage 430 to 3.7V, and the electronic device 201 can consume the battery voltage 410 to 3.7V, and display the battery status on the display 260 with a corresponding ratio (the ratio when the fully charged voltage is regarded as 100%), or display the power-off voltage 430 of the 0% state.

[0101] According to various embodiments of the present disclosure, the electronic device 201 can charge the battery 296 in a constant current mode (CC mode) and a constant voltage mode (CV mode). The electronic device 201 can charge the battery voltage 410 to a charging voltage 420 with a constant charging current 421 in the constant current mode.

[0102] Reference Figure 4B of <401> For example, when the charging current 421 is set to 2A and the charging voltage 420 is set to 4.1V, the electronic device 201 can input 2A current to the battery 296 until the battery voltage 410 approaches 4.1V. When the battery voltage 410 reaches around the charging voltage 420, the electronic device 201 can constantly maintain the battery voltage 410 in the constant voltage mode. For example, when the battery voltage 410 is charged to the charging voltage 420 of 4.1V using the charging current 421 of 2A, the electronic device 201 can operate in the constant voltage mode, in which the charging current 421 input to the battery 296 is reduced and the battery voltage 410 is maintained at 4.1V.

[0103] When the electronic device 201 is connected to the portable (external) charger after the battery voltage 410 reaches the charging voltage 420, the electronic device 201 operates in a constant voltage mode, so that it continues to be in a fully charged state. The fully charged state of the battery 296 indicates a state in which the battery voltage 410 has reached the charging voltage 420. The state in which the battery 296 continues to be charged means a state in which the electronic device 201 is connected to the portable (external) charger and continues to charge the battery 296. For the continued fully charged state, the electronic device 201 can repeatedly recharge the battery voltage 410 to the charging voltage 420. For example, referring to Figure 4Bof <402> , when the electronic device 201 is still connected to the portable charger after the battery voltage 410 reaches the charging voltage of 4.1V, the electronic device 201 can maintain the battery 296 in the constant voltage range. In this case, the battery voltage 410 can be reduced to a predetermined voltage. In the above example, when the predetermined voltage is 4.09V, the battery voltage 410 reaches the charging voltage 420 of 4.1V and then decreases to 4.09V, at which level the electronic device 201 can recharge the battery 296. Therefore, the battery voltage 410 can be charged to the battery voltage 420 of 4.1V. The electronic device 201 can set a recharging time 423, which corresponds to the time to recharge the battery 296 from the predetermined voltage to the charging voltage 420 or the recharging voltage 422. While continuing the fully charged state after reaching the charging voltage 420 , the electronic device 201 may repeat the following cycle: recharging the battery 296 during the recharging time 423 ; discharging the battery voltage 410 from the charging voltage 420 to a predetermined voltage, and then recharging the battery 296 .

[0104] When the battery voltage 410 reaches the charging voltage 420 and the fully charged state of the battery 296 continues for a predetermined time or longer, the electronic device 201 according to various embodiments of the present disclosure can reset the charging voltage 420 of the battery 296. For example, when the battery voltage 410 reaches the charging voltage 420 of 4.1V and the fully charged state continues for more than a predetermined time, the electronic device 201 can reset 422 the charging voltage 420 to 4.1V or less. In this case, the electronic device 201 can charge the battery voltage 410 to the configured charging voltage 422, that is, the recharging voltage 422.

[0105] Figure 5 is a flowchart illustrating an example operation of setting the charge / discharge information of the battery 296 by the electronic device 201 using the usage pattern information of the battery 296 according to various embodiments of the present disclosure.

[0106] At operation 501, the electronic device 201 may detect the charge / discharge state of the battery 296. The electronic device 201 may generate usage pattern information of the battery 296 based on the charge / discharge state of the battery 296. The usage pattern information may include information on the charging pattern or the discharging pattern of the battery 296.

[0107] According to various embodiments of the present disclosure, the electronic device 201 can detect the charge / discharge state of the battery 296 and can analyze the battery 296 consumption of at least one application. The electronic device 201 can use the analysis result to generate the usage information of the battery 296. The electronic device 201 can obtain the function information executed in the application or the electronic device 201 through the user login information. The electronic device 201 can obtain the time period for executing at least one application and analyze the consumption of the battery 296 caused by executing the application. That is, the electronic device 201 can generate the usage information of the battery 296 by analyzing which type of application consumes how much battery 296 in which time period.

[0108] According to various embodiments of the present disclosure, the electronic device 201 can detect the charge / discharge state of the battery 296 and analyze the number of times the battery 296 is charged / discharged. The electronic device 201 can use the analysis result to generate the usage information of the battery 296. The number of times the battery 296 is charged / discharged may include the number of times the battery 296 is charged and the number of times the battery 296 is discharged. The number of times the battery 296 is charged / discharged may include the number of times the battery 296 is fully charged to the charging voltage and then fully discharged to the power shut-off voltage. In addition, the number of battery charge / discharges can be calculated based on the battery charging time and the battery usage time. The number of times the battery 296 is charged / discharged can be cumulatively calculated from the time when the battery 296 is first purchased. The electronic device 201 can know the total number of times the battery 296 is charged / discharged so far. For example, when the number of times the battery 296 is charged / discharged from the time of purchasing the battery 296 to a specific time is 100 times, the electronic device 201 can detect the charge / discharge state of the battery 296 and know that the number of times the battery 296 is charged / discharged is 100 times. That is, the electronic device 201 may generate usage information of the battery 296 , wherein the number of times the battery 296 is charged / discharged is 100 times.

[0109] According to various embodiments of the present disclosure, the electronic device 201 can identify the number of times the battery 296 is charged / discharged based on the charging time or discharging time of the battery 296. For example, if it takes 2 hours to charge the battery 296 from the power off voltage to the charging voltage, the electronic device 201 can count the number of times the battery 296 is charged (charged for a predetermined time (e.g., 1 hour and 30 minutes) or longer) as one. In addition, if it takes 5 hours to discharge the battery 296 from the charging voltage to the power off voltage, the electronic device 201 can count the number of times the battery 296 is discharged (the battery 296 is discharged for a predetermined time (e.g., 4 hours and 30 minutes) or longer) as one. According to various embodiments, the number of charge / discharge cycles of the battery can be checked by the battery voltage change state of the battery 296. For example, the increase in the battery voltage can be checked. When the voltage increment is greater than or equal to a predetermined amount (e.g., 0.6V voltage), the number of times the battery is charged can be counted as one. In addition, the number of times the battery is discharged can be checked by the battery voltage reduction.

[0110] According to various implementations of the present disclosure, the electronic device 201 may detect the charge / discharge state of the battery 296 based on at least one of the time information and the location information. The electronic device 201 may generate usage information of the battery 296 based on the charge / discharge state of the battery 296. The method for detecting the charge / discharge state of the battery 296 based on the time information may include a method for detecting the charge / discharge state of the battery 296 in each period or every day of the week. For example, when the user consumes the battery voltage 410 by using the electronic device 201 in a specific period, the electronic device 201 may detect the charge / discharge state of the battery 296 in the period and generate usage information of the battery 296. The method for detecting the charge / discharge state of the battery 296 according to the location information may include a method for identifying the location where the battery 296 is mainly charged or the location where the battery 296 is mainly discharged, and detecting the charge / discharge state of the battery 296 at the location. For example, when the user lives in area A, the electronic device 201 may detect the charge / discharge state of the battery 296 that changes in area A and generate usage information of the battery 296.

[0111] According to various embodiments of the present disclosure, the electronic device 201 can detect the charge / discharge state of the battery 296 and analyze the state of continuous charging of the battery 296. The electronic device 201 can generate usage pattern information of the battery 296 using the analysis result.

[0112] For example, when the electronic device 201 is still connected to the travel (external) charger even after the battery voltage 410 reaches the charging voltage 420, the electronic device 201 can analyze the state of the battery 296 being continuously charged and generate the usage information of the battery 296. If the user sleeps for about 8 hours while the electronic device 201 is connected to the charger, the electronic device 201 can analyze the state of the battery being continuously charged, the recharging time, the number of times the battery is recharged, and the amount of change in the battery voltage. In operation 503, the electronic device 201 can use the generated usage to configure the charge / discharge information of the battery 296. The electronic device 201 can configure the charge / discharge information according to each usage information of the battery 296. The battery charge / discharge information may include at least one of the charging voltage, the charging current, the charging time, and the power shutoff voltage. According to various embodiments of the present disclosure, the electronic device 201 can analyze the number of times the battery is charged / discharged and use the generated usage information to configure the charge / discharge information of the battery 296. The number of times the battery 296 is charged / discharged may include the number of times the battery 296 is charged and the number of times the battery 296 is discharged. The number of times the battery 296 is charged / discharged may include the number of times the battery 296 is fully charged to the charging voltage and then fully discharged to the power shutoff voltage. The number of times the battery 296 is charged / discharged may be cumulatively calculated from the time the battery 296 is first purchased.

[0113] According to various embodiments, the number of times the battery 296 is charged / discharged can be calculated based on the charging and discharging capacity of the battery 296. For example, when the battery capacity at a specific moment is calculated as 1500mAh by the charging current and time, the electronic device 201 can know that the number of times the battery 296 is charged / discharged has reached 100 times corresponding to the capacitance. The electronic device 201 can analyze the number of times the battery is charged / discharged and generate the usage information of the battery 296, and can use the generated usage information to configure the charging / discharging information of the battery 296. According to various embodiments of the present disclosure, the charging / discharging information of the battery 296 can be configured using the usage information generated based on at least one of the time information and the location information. The electronic device 201 can use the usage information generated based on the time information to configure the charging / discharging information of the battery 296. For example, when the mode of the battery 296 fully charged to 4.3V is to use about 4.1V every lunch time, the electronic device 201 can know that the user needs a battery voltage of 4.1V at lunch time instead of a fully charged voltage of 4.3V. The electronic device 201 can use the usage information to set the charging voltage of the battery 296 to 4.1V to 4.15V. In another example, when the battery 296 fully charged to 4.3V has the following usage: the battery is used at about 3.9V on weekdays and at about 4.1V on weekends, it can be known that the electronic device 201 needs to use a battery voltage 410 of 3.9V on weekdays and a battery voltage 410 of 4.1V on weekends. The electronic device 201 can use the usage information to set the charging voltage 420 of the battery 296 to 3.9V to 3.95V on weekdays, and set the charging voltage 420 of the battery 296 to 4.1V to 4.15V on weekends. The electronic device 201 can use the usage information generated based on the location information to configure the charging / discharging information of the battery 296. For example, when the user's discharge mode is to consume 1000mAh of capacitance in a residential area, the electronic device 201 can set the charging voltage to a voltage (e.g., 4.15V, see Table 1) lower than the full charge voltage (e.g., 4-3V). When the user's discharge mode is to consume 1400mAh near a workplace, the electronic device 201 can charge the battery 296 by changing and setting the charging voltage (e.g., 4.3V).

[0114] According to various embodiments of the present disclosure, the electronic device 201 can analyze the state of continuous battery charging, and use the generated usage information to set the charging / discharging information of the battery 296. When the mode is that the fully charged state of the battery 296 lasts for more than a certain time, the electronic device 201 can use the recharging time, the number of times the battery is recharged, the change in the battery voltage 410, etc. in the state where the battery is continuously charged to set the charging / discharging information of the battery 296. For example, assume that the fully charged state of the battery 296 lasts for 7 hours every night and the charging current is 2A and the charging voltage is 4.3V at this time. At night, since the user does not use the battery 296, the electronic device 201 can set the charging voltage 420 of the battery 296 to a voltage lower than 4.3V, or set the charging current 421 to a current lower than 2A.

[0115] At operation 505, the electronic device 201 may charge or discharge the battery 296 based on the configured charge / discharge information. When the charging voltage of the battery 296 is set to 4.1V, the electronic device 201 may charge the battery 296 to 4.1V. When the charging current of the battery 296 is set to 1.8A, the electronic device 201 may charge the battery 296 at 1.8A. When the charging time of the battery is set to t, the electronic device 201 may charge the battery 296 for t hours. When the power-off voltage of the battery 296 is set to 3.7V, the electronic device 201 may discharge the battery 296 to 3.7V. Fig. 6A is a graph showing battery voltage 610 changing over time according to various embodiments of the present disclosure.

[0116] The electronic device 201 can perform a variety of functions by consuming the battery voltage 610. The electronic device 201 can charge the battery voltage 610 to the charging voltage 620 and discharge the battery voltage 610 to the power-off voltage 630. When the charging voltage 620 of the battery 296 is set to the full charging voltage, the electronic device 201 can fully charge the battery 296. When the power-off voltage of the battery 296 is set to the full discharge voltage, the electronic device 201 can fully discharge the battery 296. The electronic device 201 can generate the usage pattern information of the battery 296 based on the time information. The electronic device 201 can configure the charge / discharge information of the battery 296 by using the usage pattern information of the battery 296 generated according to the time information.

[0117] According to various embodiments of the present disclosure, the electronic device 201 can use the usage pattern information generated based on the time information to set the charging voltage 620 of the battery 296. For example, when the mode of the electronic device 201 is to use about 80% of the full charging voltage every lunch time (between 12 o'clock and 13 o'clock), the electronic device 201 can obtain about 80% of the full charging voltage (which is the battery consumption during lunch) as the charging voltage 620a of the battery 296. On the other hand, the electronic device 201 can obtain a charging voltage 620a with a certain range (80% to 90% of the full charging voltage) by adding or subtracting an arbitrary value to the obtained charging voltage 620a. The electronic device 201 can set the obtained charging voltage 620a as the charging voltage 620 during lunch. In addition, as another example, when the electronic device 201 recognizes that a mode of using about 60% of the full charge voltage after lunch, the electronic device 201 can obtain 60% of the full charge voltage (which is the battery consumption after lunch) as the charging voltage 620b of the battery 296. On the other hand, the electronic device 201 can obtain a charging voltage 620b with a certain range (60% to 70% of the full charge voltage) by adding or subtracting an arbitrary value to or from the obtained charging voltage 620b. The electronic device 201 can set the obtained charging voltage 620b as the charging voltage 620 after lunch. In addition, as another example, when the mode of the electronic device 201 is to connect it to a travel charger and charge the battery 296 at night (for example, between 22 o'clock and 8 o'clock), the electronic device 201 can obtain the minimum battery consumption (for example, about 10% of the full charge voltage) as the charging voltage 620c. The electronic device 201 can obtain a charging voltage 620c having a certain range (10% to 20% of the full charging voltage) by adding or subtracting an arbitrary value to or from the obtained charging voltage 620c. The electronic device 201 can set the obtained charging voltage 620c as the charging voltage 620 at night. The electronic device 201 can charge the battery 296 to the configured charging voltages 620a to 620c.

[0118] According to various embodiments of the present disclosure, the electronic device 201 can use the usage pattern information generated according to the time information to set the power shutoff voltage 630 of the battery 296. For example, when the mode of the electronic device 201 is that about 10% of the full charge voltage is not used every lunch time (between 12 o'clock and 13 o'clock), the electronic device 201 can obtain about 10% of the battery voltage (which is not used during lunch time) as the power shutoff voltage of the battery 296. On the other hand, the electronic device 201 can obtain a power shutoff voltage 630a with a certain range (5% to 10% of the full charge voltage) by adding or subtracting an arbitrary value to the obtained power shutoff voltage 630a. The electronic device 201 can set the obtained power shutoff voltage 630a as the power shutoff voltage 630 during lunch. In addition, as another example, when the electronic device 201 recognizes that a mode of about 30% of the fully charged voltage is not used after lunch, the electronic device 201 can obtain 30% of the battery voltage (which is not used after lunch) as the power shutoff voltage 630b of the battery 296. On the other hand, the electronic device 201 can obtain a power shutoff voltage 630b having a certain range (25% to 30% of the fully charged voltage) by adding or subtracting an arbitrary value to or from the obtained power shutoff voltage 630b. The electronic device 201 can set the obtained power shutoff voltage 630b as the power shutoff voltage 630 after lunch. The electronic device 201 can discharge the battery 296 to the configured power shutoff voltages 630a to 630b. When the charging voltage 620 of the battery 296 is set to 80% of the full charging voltage and the power shutoff voltage 630 of the battery 296 is set to 20% of the full charging voltage, the electronic device 201 can charge the battery 296 only to 80% of the full charging voltage and discharge the battery only to 20% of the full charging voltage. According to various embodiments of the present disclosure, it is needless to say that the electronic device 201 can use the usage information of the battery 296 to set the charging current, charging time, etc. of the battery 296.

[0119] Figure 6B 6 is a graph showing changes in battery voltage 610 according to various embodiments of the present disclosure for each day of the week. The electronic device 201 may generate usage pattern information of the battery 296 based on time information. The electronic device 201 may configure charge / discharge information of the battery 296 using the usage pattern information of the battery 296 generated based on time information.

[0120] According to various embodiments of the present disclosure, the electronic device 201 can use the usage information of the battery 296 according to the days of the week to set the charging voltage 620 of the battery 296. For example, when the mode of the electronic device 201 is to use about 70% of the full charge voltage on weekdays (for example, from Monday to Friday), the electronic device 201 can obtain about 70% of the full charge voltage (the voltage is the battery consumption on weekdays) as the charging voltage 620d. On the other hand, the electronic device 201 can obtain a charging voltage 620d with a certain range (70% to 80% of the full charge voltage) by adding or subtracting an arbitrary value to the obtained charging voltage 620d or from the obtained charging voltage 620d. The electronic device 201 can set the obtained charging voltage as the charging voltage 620 for weekdays. For example, when the mode of the electronic device 201 is to use about 85% of the full charge voltage on weekends (for example, Saturday to Sunday), the electronic device 201 can obtain about 90% of the full charge voltage (the voltage is the battery consumption on weekends) as the charging voltage 620e. On the other hand, the electronic device 201 can obtain a charging voltage 620e having a certain range (85% to 95% of the fully charged voltage) by adding or subtracting an arbitrary value to or from the obtained charging voltage 620e. The electronic device 201 can set the obtained charging voltage as the charging voltage 620 for the weekend. The electronic device 201 can charge the battery 296 to the configured charging voltage 620d to 620e.

[0121] According to various embodiments of the present disclosure, the electronic device 201 may use the usage pattern information of the battery 296 according to each day of the week to set the power shutoff voltage 630 of the battery 296. For example, when the mode of the electronic device 201 is that about 30% of the fully charged voltage is not used on weekdays (e.g., from Monday to Friday), the electronic device 201 may obtain about 30% of the battery voltage (which is not used on weekdays) as the power shutoff voltage 630c of the battery 296. On the other hand, the electronic device 201 may obtain a power shutoff voltage 630c with a certain range (25% to 30% of the fully charged voltage) by adding or subtracting an arbitrary value to or from the obtained power shutoff voltage 630c. The electronic device 201 may set the obtained power shutoff voltage 630c as the power shutoff voltage 630 on weekdays. In addition, as another example, when the electronic device 201 recognizes that a mode of about 10% of the fully charged voltage is not used on weekends, the electronic device 201 can obtain about 10% of the battery voltage (which is not used on weekends) as the power shutoff voltage 630d of the battery 296. On the other hand, the electronic device 201 can obtain a power shutoff voltage 630d with a certain range (5% to 10% of the fully charged voltage) by adding or subtracting an arbitrary value to or from the obtained power shutoff voltage 630d. The electronic device 201 can set the obtained power shutoff voltage 630d as the power shutoff voltage 630 on weekends. The electronic device 201 can discharge the battery 296 to the configured power shutoff voltage 630c to 630d. According to various embodiments of the present disclosure, it is needless to say that the electronic device 201 can use the usage mode information of the battery 296 to set the charging current, charging time, etc. of the battery 296.

[0122] Figure 6C is a graph showing battery voltage 610 as a function of position according to various embodiments of the present disclosure.

[0123] The electronic device 201 may generate the usage pattern information of the battery 296 based on the location information. The electronic device 201 may configure the charge / discharge information of the battery 296 by using the usage pattern information of the battery 296 generated based on the location information.

[0124] According to various embodiments of the present disclosure, the electronic device 201 can use the usage information of the battery 296 according to the location to set the charging voltage 620 of the battery 296. For example, it is assumed that the A area 601 is the location where the user's workplace is located, the B area 602 is the location where the user first goes, and the C area 603 is the location where the user lives. In addition, it is assumed that the A area 601 and the C area 603 are places where the battery 296 can be easily charged. When the electronic device 201 is in a manner to use a 60% full charge voltage while the electronic device 201 is in the A area 601, the electronic device 201 can obtain about 60% of the full charge voltage as the charging voltage 620f during the period in the A area 601. On the other hand, the electronic device 201 can obtain a certain range of charging voltage 620f (60% to 70% of the full charge voltage) by adding or subtracting an arbitrary value to the obtained charging voltage 620f. The electronic device 201 can set the obtained charging voltage 620f as the charging voltage 620 at the A area 601. As another example, when there is a schedule as follows: the electronic device 201 is in the A area 601, goes to the B area 602 at about 12 o'clock (there is no battery usage information), and stays in the B area 602 until about 16:00, since charging the battery 296 may be inconvenient, the electronic device 201 can obtain the full charge voltage as the charging voltage 620g during the period of being in the B area. The electronic device 201 can set the obtained charging voltage 620g as the charging voltage 620 at the B area 602. On the other hand, before going from the A area 601 to the B area, the trip to the B area 602 is recognized, and the full charge voltage can be obtained as the charging voltage 620g during charging.

[0125] For another example, when the electronic device 201 is in a mode that uses approximately 80% of the fully charged voltage while it is in the C region 603, the electronic device 201 can obtain approximately 80% of the fully charged voltage as the charging voltage 620h during the C region 603. On the other hand, the electronic device 201 can obtain a charging voltage 620h with a certain range (80% to 90% of the fully charged voltage) by adding or subtracting an arbitrary value to or from the obtained charging voltage 620h. The electronic device 201 sets the obtained charging voltage 620h as the charging voltage 620 at the C region 603. The electronic device 201 can charge the battery 296 to the configured charging voltage 620f to 620h. According to various embodiments of the present disclosure, it is needless to say that the electronic device 201 can use the usage information of the battery 296 to set the charging current, power cut-off voltage, charging time, etc. of the battery 296 and the charging voltage 620.

[0126] Fig.6D2 is a diagram showing the change of the charging current of the battery over time according to various embodiments of the present disclosure. The electronic device 201 can analyze the state of continuous charging of the battery 296 and generate the usage information of the battery 296. The electronic device 201 can use the generated usage information of the battery 296 to configure the charging / discharging information of the battery 296. The electronic device 201 can use the usage information generated by analyzing the state of continuous charging of the battery 296 to configure the charging current 621 of the battery 296. For example, when the mode of the electronic device 201 is to maintain the charging state for 2 hours during the day, the electronic device 201 can set the charging current 621a of the battery 296 to 2A. This is to increase the charging speed by increasing the charging current 621, because the battery is in a shorter state of continuous charging during the day. For example, when the mode of the electronic device 201 is to maintain the charging state for 10 hours at night, the electronic device 201 can set the charging current 621b of the battery 296 to 1.5A. This is to slow down the charging speed by reducing the charging current 621, because the battery is in a longer state of continuous charging at night.

[0127] According to various embodiments of the present disclosure, when the charging state of the battery 296 is continued after the charging of the battery 296 is completed based on the configured charging / discharging information, the state of the battery 296 being continuously charged can be analyzed, and the usage information of the battery 296 can be generated. The electronic device 201 can use the generated usage information to reconfigure the charging / discharging information of the battery 296. For example, when the mode is to fully charge the battery 296 to the charging voltage every night and maintain the fully charged state of the battery, the electronic device 201 can reconfigure the charging current, charging voltage and charging time of the battery 296. Assume that the charging time is 30 minutes, the charging current is 2A and the charging voltage is 4.3V. The electronic device 201 is connected to a travel charger and can charge the battery 296 to the charging voltage (4.3V) every night. When the battery voltage has reached the charging voltage 4.3V and continues to be fully charged, the electronic device 201 can reconfigure the charging voltage of the battery 296 to 4.2V to prevent the degradation of the battery 296. Furthermore, the electronic device 201 may reset the charging current of the battery 296 to 1.8 A, or reset the charging time of the battery 296 to 60 minutes, in order to prevent the degradation of the battery 296 .

[0128] Figure 7 is a flowchart illustrating an operation of selecting one charging / discharging mode among displayed battery charging / discharging modes and setting charging / discharging information according to the corresponding mode according to various embodiments of the present disclosure.

[0129] The electronic device 201 may display the type of battery charge / discharge mode at operation 701. The type of battery charge / discharge mode may include a full charge / discharge mode, a user configuration mode, and an automatic configuration mode.

[0130] At operation 703, the electronic device 201 may receive an input for selecting one of the displayed battery charging / discharging modes. The electronic device 201 may receive an input via the input device 250 (eg, a touch panel).

[0131] At operation 705, the electronic device 201 may configure the charging / discharging information of the electronic device 201 based on the battery charging / discharging mode corresponding to the received input. When the electronic device 201 receives the input for entering the full charging / discharging mode, the electronic device 201 may set the charging voltage to the full charging voltage or set the power-off voltage to the full discharging voltage.

[0132] According to various embodiments of the present disclosure, when the electronic device 201 receives an input for entering a user configuration mode, the electronic device 201 may receive an input corresponding to the charging / discharging information desired by the user from the user. For example, the electronic device 201 may receive an input corresponding to a charging voltage of 4.1V from the user. According to various embodiments of the present disclosure, the electronic device 201 may receive information about a battery usage period desired by the user. According to various embodiments, the electronic device 201 may display the number of charging / discharging cycles during which the battery 296 can be stably used on the display 260, and may receive the number of battery charging / discharging cycles desired by the user through the input device 250. On the other hand, when it is assumed that the number of battery charging / discharging is calculated once a day, the electronic device 201 may display a chargeable / discharging cycle capable of stably charging / discharging the battery 296 on the display 260, and may receive the battery charging and discharging period desired by the user from the input device 250. The electronic device 201 may receive an input through the input device 250 (e.g., a touch panel). When an input corresponding to a charging voltage is received from the user, the electronic device 201 may set the charging voltage based on the input. The electronic device 201 may receive not only a charging voltage but also an input corresponding to a charging current, a charging time, and a power-off voltage from a user. The electronic device 201 may set charging / discharging information based on the input.

[0133] According to various embodiments of the present disclosure, when the electronic device 201 receives an input to enter the automatic configuration mode, as shown in FIG. Figure 5 As described above, the electronic device 201 may generate usage information of the battery 296 based on the charge / discharge state of the battery 296. The electronic device 201 may configure the charge / discharge information of the battery 296 using the generated usage information.

[0134] According to various embodiments of the present disclosure, the electronic device 201 may send charging / discharging information corresponding to each charging and discharging mode to the external charging device via the communication module 220. This is because the external charging device itself may not be able to generate usage information of the battery 296. The external charging device may charge the battery 296 based on the sent charging / discharging information.

[0135] At operation 707, the electronic device 201 may charge or discharge the battery 296 based on the configured charge / discharge information. For example, when the battery charge / discharge mode is a full charge / discharge mode, the electronic device 201 may charge the battery 296 to a full charge voltage and discharge the battery 296 to a full discharge voltage. When the battery charge / discharge mode is a user configuration mode, the electronic device 201 may charge the battery 296 to a charge voltage obtained from a user and discharge the battery 296 to a power-off voltage obtained from a user. The electronic device 201 may charge the battery 296 using a charging current obtained from a user. The electronic device 201 may charge the battery 296 based on a charging time obtained from a user. When the battery charge / discharge mode is an automatic configuration mode, the electronic device 201 may charge or discharge the battery 296 to a charge voltage or a power-off voltage obtained based on information on how the battery 296 is used.

[0136] Figure 8 is a diagram illustrating an electronic device for displaying various types of battery charging / discharging modes according to various embodiments of the present disclosure.

[0137] The electronic device 201 may display the type of battery charge / discharge mode via the display 260. The type of battery charge / discharge mode may include a full charge / discharge mode 801, a user configuration mode 802, and an automatic configuration mode 803. The full charge / discharge mode may be a mode in which the charging voltage of the battery 296 is configured as a full charge voltage or a mode in which the power-off voltage of the battery 296 is configured as a full discharge voltage. When the user selects the full charge / discharge mode 801, the electronic device 201 may charge the battery 296 to a full charge voltage or discharge the battery 296 to a full discharge voltage. The user configuration mode 802 is a mode in which the charging / discharging information of the battery 296 is configured using the battery configuration information obtained from the user. The battery configuration information or the battery charge / discharge information may include at least one of the charging voltage, the charging current, the charging time, and the power-off voltage. The electronic device 201 may charge or discharge the battery 296 based on the configured charging / discharging information. In addition, the user configuration mode 802 may configure the charging / discharging information of the electronic device 201 to a predetermined value. For example, in the case of user configuration mode 802, the electronic device 201 can set the charging voltage to a predetermined voltage (e.g., 4.1V) or the power off voltage to a predetermined voltage (e.g., 3.7V), or the charging current to a predetermined current (e.g., 2A) without obtaining charging / discharging information from the user. The predetermined charging / discharging information can be predetermined by the battery manufacturer taking into account the battery usage period and the battery consumption. The automatic configuration mode 803 can be a mode for configuring the charging / discharging information of the battery 296 using the usage information of the battery 296. When the user selects the automatic configuration mode 803, the electronic device 201 can charge or discharge the battery 296 based on the configured charging / discharging information.
