2 is a flowchart illustrating a method of selecting a charging method of the battery 189 and controlling the charging strength according to an exemplary embodiment. According to an embodiment, in operation 201 , the processor (eg, the processor 120 of FIG. 1 ) may determine whether a charging device is connected to the electronic device (eg, the electronic device 101 of FIG. 1 ). The charging device may include a wired charging device or a wireless charging device. When the charging device is connected to the electronic device 101 (operation 201 - Yes), the processor 120 may proceed to operation 203 . When the charging device is not connected to the electronic device 101 (operation 201 - No), the processor 120 may terminate the operation of FIG. 2 without charging the battery (eg, the battery 189 of FIG. 1 ). can

In operation 203 , the processor 120 may determine whether a charging end time (eg, a charging end time 427 of FIG. 4 ) is set in the electronic device 101 . The charging end time 427 may be a charging end time 427 separately set by the user or an alarm time set by the user. When the charging end time 427 is set in the electronic device 101 (operation 203 - Yes), the processor 120 may proceed to operation 205 . When the charging end time 427 is not set in the electronic device 101 (operation 203 -No), the processor 120 may proceed to operation 209 .

In operation 205 , the processor 120 may determine whether a charging start time (eg, a charging start time 425 of FIG. 5 ) is included in the long-term charging time period. The charging start time 425 may be a time at which the electronic device 101 and the charging device are connected. The long-term charging time period may include a first long-term charging time period (eg, the first long-term charging time period 1010 of FIG. 10 ) or a second long-term charging time period (eg, the second long-term charging time period 1110 of FIG. 11 ). For example, the long-term charging time period may be the first long-term charging time period 1010 . As another example, the long-term charging time period may be the second long-term charging time period 1110 . When the charging start time 425 is included in the long-term charging time period (operation 205 - Yes), the processor 120 may proceed to operation 207 . If the charging start time 425 is not included in the long-term charging time period (operation 203 -No), the processor 120 may proceed to operation 209 .

In operation 207 , the processor 120 may determine whether there is a user's consent or permission setting. For example, the user's consent may be obtained by the user touching and inputting a UI popped up on the display module (eg, the display module 160 of FIG. 1 ). As another example, the user may activate a menu or button allowing execution of operations 213 and lower in the setting window. When there is a user's consent or permission setting (operation 207 - Yes), the processor 120 may proceed to operation 213 . If there is no user consent or permission setting (operation 207 -No), the processor 120 may proceed to operation 209 .

If at least one of operations 203 , 205 , and 207 is not satisfied, the processor 120 may perform fast charging of the battery 189 in operation 209 . When fast charging is performed, the processor 120 may determine whether the level of the battery 189 has reached 100% in operation 211 . When the level of the battery 189 reaches 100% (operation 211 - Yes), the processor 120 may proceed to operation 229 . When the level of the battery 189 is less than 100% (operation 211 -No), the processor 120 may proceed to operation 209 .

When operations 201 , 203 , 205 , and 207 are all satisfied, the processor 120 may determine whether the current level of the battery 189 is equal to or greater than a target charge amount in operation 213 . The target charge amount may mean a level of the battery 189 corresponding to the second target charge amount in operation 517 of FIG. 5 . If the current level of the battery 189 is equal to or greater than the target charge amount (operation 213 - Yes), the processor 120 may proceed to operation 229 . When the current level of the battery 189 is less than the target charge amount (operation 213 -No), the processor 120 may proceed to operation 215 .

The processor 120 may calculate the remaining charging time in operation 215 . The remaining charging time may be calculated by subtracting the charging start time 425 from the charging end time 427 . For example, the remaining charging time may be calculated by subtracting the time at which the charging device is connected to the electronic device 101 from the time at which the alarm is set.

The processor 120 may check the current level of the battery 189 in operation 217 . The processor 120 may calculate the charge strength in operation 219 . The charging strength may correspond to the charging strength in the graph 420 of FIG. 4 . The charging strength may be calculated using the remaining charging time, the current level of the battery 189, and the target charging amount. For example, the charging strength may be calculated by multiplying a value obtained by subtracting the current level of the battery 189 from the target charging amount by the total capacity of the battery 189 and dividing by the remaining charging time.

In operation 221 , the processor 120 may determine whether heat is generated in the battery 189 . For example, when the temperature of the battery 189 is equal to or higher than the charge limit start temperature (eg, the charge limit start temperature 421 of FIG. 4 ), it may be determined that heat is generated in the battery 189 . The heat of the battery 189 occurs when the temperature of the battery 189 is less than the charge-limiting start temperature 421 or higher (for example, the charge cut-off temperature 423 in FIG. 4) and when the temperature of the battery 189 stops charging. It may be divided into a case where the temperature is higher than 421 . When heat is generated in the battery 189 (operation 221 - Yes), the processor 120 may proceed to operation 224 . When heat is not generated in the battery 189 (operation 221 -No), the processor 120 may proceed to operation 223 .

In operation 223 , the processor 120 may control the charge strength through the first equation (eg, the first equation 310 of FIG. 3 ). For example, when the temperature of the battery 189 is less than the charge limit start temperature 421 , the processor 120 may control the charge strength of the battery 189 through the first equation 310 .

In operation 224 , the processor 120 may determine whether the temperature of the battery 189 is equal to or greater than the charge cutoff temperature 421 . When the temperature of the battery 189 is equal to or higher than the charge cutoff temperature 421 (operation 224 - Yes), the processor 120 may proceed to operation 229 . When the temperature of the battery 189 is less than the charge cutoff temperature 421 (operation 224 -No), the processor 120 may proceed to operation 225 .

In operation 225 , the processor 120 may control the charge strength through the second equation (eg, the second equation 320 of FIG. 3 ). For example, when the temperature of the battery 189 is greater than or equal to the charge limit start temperature 421 and less than the charge cutoff temperature 421 , the processor 120 controls the charge strength of the battery 189 through the second equation (320). can do.

In operation 227 , the processor 120 may perform charging with a set charging intensity. As an example, the set charging strength may be a charging strength derived through the first equation (310). As another example, the set charging strength may correspond to the charging strength derived through the second equation (320). In operation 213 , when the processor 120 determines that the level of the current battery 189 is equal to or greater than the target charge amount, charging may be stopped in operation 229 .

3 is a diagram for explaining charging equations for controlling the charging strength of the battery 189 . According to an embodiment, the first equation 310 or the second equation 320 may be applied in controlling the charging strength according to the current temperature of the battery (eg, the battery 189 of FIG. 1 ). For example, when the current temperature of the battery 189 is less than the charge limit start temperature (eg, the charge limit start temperature 421 of FIG. 4 ), the charge intensity may be controlled through the first equation 310 . As another example, if the current temperature of the battery 189 is less than the charge cutoff temperature (eg, the charge cutoff temperature 423 in FIG. 4 ) above the charge limit start temperature 421 , the charge strength is controlled through the second equation 320 . can As another example, when the current temperature of the battery 189 is equal to or higher than the charge cutoff temperature 421 , charging may be stopped.

The first charge strength derived from the first equation (310) may show a tendency to increase as the amount of remaining charge increases GM-202011-267-1. The remaining charge amount may be calculated as a value obtained by subtracting the current level of the battery 189 from the target charge amount multiplied by the maximum capacity of the battery 189 . The target charge amount and the current level of the battery 189 may correspond to the target charge amount and the current level of the battery 189 described in operation 213 of FIG. 2 . For example, if the target charge amount is 80%, the current level of the battery 189 is 20%, and the maximum capacity of the battery 189 is 4000mAh, the remaining charge amount may be 2400mAh.

The first charging strength may show a tendency to decrease as the remaining charging time increases. The remaining charging time may be calculated by subtracting the current time from the charging end time 427 . For example, if the alarm time corresponding to the charging end time 427 is set at 8:00 AM and the current time is 2:00 AM, the remaining charging time may be 6 hours. Accordingly, when the remaining charge amount is 2400 mAh, the first charge strength may be calculated as 400 mA.

As for the second charge intensity derived from the second equation (320), temperature may be added as a variable to the first charge intensity. A description of the remaining charging amount and the remaining charging time described in the first charging strength will be omitted.

The second charge strength may show a tendency to increase as the value obtained by subtracting the current temperature of the battery 189 from the charge cutoff temperature 421 increases. Accordingly, as the temperature of the current battery 189 increases, the second charge strength may tend to decrease. For example, when the charge cutoff temperature 421 is 50 degrees, the charge limit start temperature 421 is 40 degrees, and the temperature of the current battery 189 is 42 degrees, the charge cutoff temperature 421 is higher than the calculated second charge intensity. When the temperature of the battery 189 is 50 degrees and the current temperature of the battery 189 is 48 degrees, the calculated second charge strength may be smaller.

The second charge strength may show a tendency to decrease as the value obtained by subtracting the charge limit start temperature 421 from the charge cutoff temperature 421 increases. The charge cutoff temperature 421 or the charge limit start temperature 421 may vary depending on the physical properties of the battery 189 or the chemical properties of the battery 189 . The charging limit start temperature 421 may be a start temperature at which the battery 189 is considered to require charging limit due to heat generation. The charge cutoff temperature 421 may be a minimum temperature at which the battery 189 should not be charged any more due to excessive heat generation.

According to the present embodiment, the processor 120 controls the battery 189 to be charged with the first or second charging strength, so that the battery 189 is charged with a lower strength than the charging strength during rapid charging. By controlling it, deterioration of the battery 189 can be prevented.

4 is a graph illustrating a method of controlling charging by the electronic device 101 . A horizontal axis of the graph 410 and the graph 420 according to an embodiment may mean time. The processor (eg, the processor 120 of FIG. 1 ) may measure the temperature of the battery (eg, the battery 189 of FIG. 1 ) every specified time. The specified time may be a preset time or a user-specified time. For example, the processor 120 may measure the temperature of the battery 189 every 10 minutes.

The horizontal axis may be divided into a first section, a second section, and a third section, which are a plurality of sections indicating a section before charging and during charging. The vertical axis may mean the level of the battery 189 . For example, the level of the battery 189 may increase to 100% from the level of the battery 189 at the charging start time 425 .

As another example, when charging is performed in a state where the target charge amount is set, the level of the battery 189 may increase from the level of the battery 189 at the charge start time 425 to the target charge amount. For example, in the graph 410 , the level of the battery 189 at the charging start time 425 may be L1 . Since the temperature of the current battery 189 at the start point of the first section is less than the charge limit start temperature 421, the charge intensity I1 is derived through the first equation 310 (eg, the first equation 310 in FIG. 3 ). can be As charging is performed with the derived charging strength I1 , the level of the battery 189 may increase from L1 to L2 in the first period.

At the starting point of the second section, the current temperature of the battery 189 is higher than the charge limit start temperature 421 and less than the charge cutoff temperature 421, so through the second equation (eg, the second equation (320) in FIG. 3 ) The charge strength I2 can be derived. As charging is performed with the derived charging strength I2 , the level of the battery 189 may increase from L2 to L3 in the second section.

Since the current temperature of the battery 189 at the start point of the third section is less than the charge limit start temperature 421 , the charge intensity I3 may be derived through the first equation 310 . As charging is performed with the derived charging strength I3 , the battery 189 may increase from the level L3 to the target charging amount in the third section. As the level of the battery 189 reaches the target charge amount, the processor 120 may stop charging the battery 189 .

In the graph 420 according to an embodiment, the horizontal axis may be the same time axis as the graph 410 . The left vertical axis may mean the charging intensity for charging the battery 189 . The charge strength may be calculated by the first equation (310) or the second equation (320). The right vertical axis may mean the temperature of the battery 189 . There may exist a charge limit start temperature 421, which is a threshold temperature at which the application of the equation for calculating the charge strength, can be different, and a charge cutoff temperature 421, which is a threshold temperature at which charging must be stopped to prevent damage to the battery 189. have.

According to the present embodiment, by not exposing the temperature of the battery 189 to a high temperature, deterioration and ignition of the battery 189 can be prevented and burns of the user can be prevented.

5 is a flowchart illustrating a method of determining a target charge amount of the battery 189 . According to an embodiment, the processor (eg, the processor 120 of FIG. 1 ) may store the daily battery 189 usage in a memory (eg, the memory 130 of FIG. 1 ) in operation 501 . Daily battery 189 usage may be stored for each date. In operation 503 , the processor 120 may determine whether the number of stored days is equal to or greater than the first period. The first period may be a preset period or a user-set period. For example, the first period may be one week.

For example, when the number of days in which the battery 189 usage is stored is less than one week (operation 503 - No), the processor 120 may additionally store the daily battery 189 usage in operation 501 . As another example, when the number of days in which the usage of the battery 189 is stored is one week or more (operation 503 - Yes), the processor 120 may proceed to operation 505 .

In operation 505 , the processor 120 may extract the maximum amount of usage from among the daily usage of the battery 189 stored during the first recent period from the charging date. The charging date may mean a reference date on which the first target charging amount is determined in operation 507 . For example, if the charging date is February 8 and the first period is one week, the maximum amount of usage among the daily battery 189 usage stored from February 1 to February 7 may be extracted.

In operation 507 , the processor 120 may set a value obtained by adding a margin to the maximum usage amount as the first target charging amount. The margin may be a preset value or a user-set value. For example, assuming that the maximum amount of use of the daily battery 189 stored for one week is 70%, 80% plus a margin of 10% may be set as the first target charge amount.

In operation 509 , the processor 120 may determine whether the first target charging amount exceeds the second target charging amount. The second target charge amount may be a target charge amount preset in the electronic device (eg, the electronic device 101 of FIG. 1 ). When the first target charging amount exceeds the second target charging amount (operation 509 - YES), the processor 120 may substitute the value of the first target charging amount into the second target charging amount in operation 511 . For example, when the preset second target charging amount is 70% and the newly set first target charging amount is 85%, the second target charging amount may be reset to 85%.

If the first target charging amount is less than or equal to the second target charging amount (operation 509 - NO), in operation 513 , the processor 120 may determine whether the first target charging amount is smaller than the second target charging amount by a first value or more. The first numerical value may be a preset numerical value or a numerical value set by a user. For example, the first value may be 5%.

When the first target charging amount is smaller than the second target charging amount by a first value or more (operation 513 - YES), the processor 120 may decrease the second target charging amount by the second value in operation 515 . The second numerical value may be a preset numerical value or a numerical value set by a user. For example, the second value may be 1%. When the first target charge amount is not smaller than the second target charge amount by a first value or more (operation 513 - NO), the processor 120 may charge the battery based on the second target charge amount in operation 517 .

According to the present embodiment, when the battery 189 is charged based on the second target amount of charge, the processor 120 performs a second value that is a value at which the battery is actually charged based on the first target amount of charge reflecting the user's usage pattern. By correcting the target charge amount, it is possible to prevent the deterioration of the battery 189 from proceeding due to the battery 189 being 100% charged.

6 is a diagram for explaining the first condition. According to an embodiment, in operation 601 , the processor (eg, the processor 120 of FIG. 1 ) sends an alarm to the electronic device (eg, the electronic device 101 of FIG. 1 ) for a first sequential day on a daily basis. It can be determined whether this is set. The first consecutive day may be the number of days designated in advance or the number of days set by the user. For example, the first consecutive day may be 7 days. When an alarm is set in the electronic device 101 for the first consecutive day in a daily cycle (operations 601 - Yes), the processor 120 may proceed to operation 603 . The processor 120 may proceed to operation 611 when an alarm is set in the electronic device 101 at a time interval longer than the daily cycle or an alarm is set for a day less than the first consecutive day in a daily cycle (operations 601 - No).

In operation 603 , the processor 120 may determine whether the electronic device 101 is in a no-input state from a time when charging of the battery 189 is started to a set alarm time during the first consecutive day in a daily cycle. If the electronic device 101 does not receive any input from the time the battery 189 starts charging to the set alarm time during the first consecutive day in a daily cycle (operation 603 - Yes), the processor 120 may proceed to operation 605 . . When an input to the electronic device 101 is detected before the set alarm time (operation 603 - No), the processor 120 may proceed to operation 611 . In operation 605 , the processor 120 may store the charging start time in the memory (eg, the memory 130 of FIG. 1 ) for the first consecutive day in a daily cycle.

In operation 607 , the processor 120 performs the earliest first time (eg, the first time 1020 of FIG. 10 ) and the second latest time (eg, the second time 1030 of FIG. 10 ) among the stored charging start times. )) to determine whether the interval is less than 1 hour. For example, among the stored charging start times, when the earliest first time 1020 is 12:30 AM and the latest second time 1030 is 01:30 AM, it is determined that the interval between the two times is less than 1 hour can do. When the interval between the first time 1020 and the second time 1030 is 1 hour or less (operation 607 - Yes), the processor 120 may proceed to operation 609 . When the interval between the first time 1020 and the second time 1030 exceeds one hour (operation 607 - No), the processor 120 may proceed to operation 611 .

The processor 120 may determine that the first condition is satisfied in operation 609 . If any one of operations 601, 603, and 607 is not satisfied, the processor 120 may determine in operation 611 that the first condition is not satisfied. When it is determined that the first condition is not satisfied, the processor 120 may control the battery 189 to be charged in a general charging method.

7 is a diagram for explaining the second condition. According to an embodiment, in operation 701 , the processor (eg, the processor 120 of FIG. 1 ) determines whether an alarm is set in the electronic device (eg, the electronic device 101 of FIG. 1 ) for a second consecutive day in a one-week cycle. can judge For example, it may be determined whether an alarm is set for Mondays for a second consecutive day from the first Monday in January to the first Monday in February. The second consecutive day may be the number of days designated in advance or the number of days set by the user. For example, the second consecutive day may be five days. When an alarm is set in the electronic device 101 for the second consecutive day in a one-week cycle (operations 701 - Yes), the processor 120 may proceed to operation 703 . When an alarm is set in the electronic device 101 every cycle longer than a one-week cycle or an alarm is set in the electronic device 101 for a period of less than a second consecutive day in a one-week cycle (operation 701 - No) The process may proceed to operation 711 .

In operation 703 , the processor 120 may determine whether the electronic device 101 is in a no-input state from a time when charging of the battery 189 is started to a set alarm time during the second consecutive day in a one-week cycle. If the electronic device 101 does not receive any input from the time when charging of the battery 189 is started to the set alarm time, respectively, for the second consecutive day in a one-week cycle (operation 703 - Yes), the processor 120 may proceed to operation 705 . have. When an input to the electronic device 101 is detected before the set alarm time (operation 703 -No), the processor 120 may proceed to operation 711 . In operation 705 , the processor 120 may store the charging start time in the memory (eg, the memory 130 of FIG. 1 ) for the second consecutive day in a one-week cycle.

In operation 707 , the processor 120 performs a third earliest time (eg, a third time 1120 of FIG. 11 ) and a fourth latest time (eg, a fourth time 1130 of FIG. 11 ) among the stored charging start times. )) to determine whether the interval is less than 1 hour. For example, when the third time (1120) stored on the first Monday in February is the earliest at 12:30 AM and the fourth time (1130) stored on the third Monday in February is the latest at 12:30 AM, two times can be determined to be less than 1 hour apart. When the interval between the third time 1120 and the fourth time 1130 is 1 hour or less (operation 707 - Yes), the processor 120 may proceed to operation 709 . When the interval between the first time 1020 and the second time 1030 exceeds one hour (operation 707 - No), the processor 120 may proceed to operation 711 .

The third time 1120 and the fourth time 1130 may be compared differently for each day of the week. For example, it may be determined whether the third time 1120 and the fourth time 1130 are compared to one hour or less among charging start times stored every Monday. As another example, it may be determined whether the third time 1120 and the fourth time 1130 are compared to one hour or less among charging start times stored on every Saturday.

The processor 120 may determine that the second condition is satisfied in operation 709 . When any one of operations 701, 703, and 707 is not satisfied, the processor 120 may determine in operation 711 that the second condition is not satisfied. The second condition may be determined differently for each day of the week. For example, when the third time 1120 and the fourth time of Monday satisfy operation 707, it may be determined that the second condition is satisfied for Monday. As another example, when the third time 1120 and the fourth time 1130 of Saturday do not satisfy operation 707, it may be determined that the second condition of Saturday is not satisfied. When it is determined that the second condition is not satisfied, the processor 120 may control the battery 189 to be charged in a general charging method.

8 is a flowchart illustrating a method of setting the first long-term charging time period 1010 when the first condition is satisfied. According to an embodiment, the processor (eg, the processor 120 of FIG. 1 ) may determine whether the first condition is satisfied in operation 801 . The first condition may correspond to the first condition in operation 609 of FIG. 6 . When the first condition is satisfied (operation 801 - Yes), the processor 120 may proceed to operation 803 . When the first condition is not satisfied (operation 801 - No), the processor 120 may end the operation of FIG. 8 .

In operation 803 , the processor 120 receives a second time from a first reference time (eg, the first reference time 1040 of FIG. 10 ) that is earlier than the first time (eg, the first time 1020 of FIG. 10 ) by a specified time. The first time zone may be set up to a second reference time (eg, the second reference time 1050 of FIG. 10 ) that is later than the second time (eg, the second time 1030 of FIG. 10 ) by a specified time. The first time 1020 and the second time 1030 may correspond to the first time 1020 and the second time 1030 in operation 607 of FIG. 6 , respectively. For example, when the first time 1020 is 12:30 AM and the second time 1030 is 01:30 AM, the first reference time 1040 is 12:00 AM 30 minutes earlier than 12:30 AM. , and 02:00 AM, 30 minutes later than 01:30 AM, may be set as the second reference time 1050, and from 12:00 AM to 02:00 AM may be set as the first time zone.

In operation 805 , the processor 120 may determine whether charging of the battery (eg, the battery 189 of FIG. 1 ) starts for a third consecutive day in a daily cycle at a time not included in the first time zone. The third consecutive day may be the number of days designated in advance or the number of days set by the user. For example, the third consecutive day may be three days.

Charging of the battery 189 is started for the third consecutive day with a daily cycle at a time included in the first time zone, or charging the battery 189 for a third consecutive day with a longer cycle than the daily cycle at a time not included in the first time zone. When the battery 189 starts charging for days less than the third consecutive day in a daily cycle at a time not included in the first time zone (operation 805 - No), the processor 120 may proceed to operation 807 . The processor 120 may set the first time period as the first long-term charging time period (eg, the first long-term charging time period 1010 of FIG. 10 ) in operation 807 .

When charging of the battery 189 is started for the third consecutive day in a daily cycle at a time not included in the first time zone (operation 805 - Yes), the processor 120 may proceed to operation 809 . In order to reset the first long-term charging time period, the processor 120 may delete the preset first time period in operation 809 and proceed from operation 805 of FIG. 8 to operation 601 of FIG. 6 . The processor 120 may perform operations 601 , 603 , 605 , 607 , and 609 in FIG. 6 and proceed to operation 801 of FIG. 8 again.

For example, assuming that the first time zone is set from 12:00 AM to 02:00 AM, it is 11:47 PM, 11:00 PM, and 11:30 PM for 3 consecutive days, Monday, Tuesday, and Wednesday, respectively. When charging of the battery 189 is started at can proceed. In operation 801 , the processor 120 may determine again whether the first condition is satisfied based on the contents performed in operations 601 , 603 , 605 , 607 , and 609 .

According to an embodiment, the processor (eg, the processor 120 of FIG. 1 ) may determine whether the second condition is satisfied in operation 901 . The second condition may correspond to the second condition in operation 709 of FIG. 7 . It may be determined whether the second condition is satisfied for each day of the week. When the second condition is satisfied (operation 901 - Yes), the processor 120 may proceed to operation 903 . When the second condition is not satisfied (operation 901 - No), the processor 120 may end the operation of FIG. 9 . In operation 903 , the processor 120 performs a second time from a third reference time (eg, the third reference time 1140 of FIG. 11 ) that is earlier than the third time (eg, the third time 1120 of FIG. 11 ) by a specified time. The second time zone may be set up to a fourth reference time (eg, the fourth reference time 1150 of FIG. 11 ) later than the fourth time (eg, the fourth time 1130 of FIG. 11 ) by a specified time.

The third time 1120 and the fourth time 1130 may correspond to the third time 1120 and the fourth time 1130 in operation 707 of FIG. 7 , respectively. For example, when the third time 1120 is 12:30 AM and the fourth time 1130 is 01:30 AM, the third reference time 1140 is 12:00 AM 30 minutes earlier than 12:30 AM. and 02:00 AM, 30 minutes later than 01:30 AM, may be set as the fourth reference time 1150 to set the second time zone from 12:00 AM to 02:00 AM. The second time zone may be set differently for each day of the week.

In operation 905 , the processor 120 may determine whether charging of the battery (eg, the battery 189 of FIG. 1 ) starts for a third consecutive day in a one-week cycle at a time not included in the second time zone. The third consecutive day may correspond to the third consecutive day in operation 805 of FIG. 8 .

At a time included in the second time zone, charging of the battery 189 is started for the third consecutive day with a cycle of one week, or the battery 189 for a third consecutive day with a cycle longer than one week at a time not included in the second time zone. When charging is started or charging of the battery 189 is started for days less than the third consecutive day in a one-week cycle at a time not included in the second time zone (operation 905 - No), the processor 120 may proceed to operation 907. have. The processor 120 may set the second time period as the second long-term charging time period (eg, the second long-term charging station 1110 of FIG. 11 ) in operation 907 .

When charging of the battery 189 is started for the third consecutive day in a one-week cycle at a time not included in the second time zone (operation 905 - Yes), the processor 120 may proceed to operation 909 . In order to reset the second long-term charging time period, the processor 120 may delete the preset second time period in operation 909 and proceed from operation 905 of FIG. 9 to operation 701 of FIG. 7 . The processor 120 may perform operations 701 , 703 , 705 , 707 , and 709 in FIG. 7 , and then proceed to operation 901 of FIG. 9 again.

For example, assuming that the second time zone of Monday is set from 12:00 AM to 02:00 AM, 11 for 3 consecutive days: 2nd Monday in February, 3rd Monday in February, and 4th Monday in February :47 PM, 11:00 PM, 11:30 PM when the charging of the battery 189 is started, the processor 120 deletes the first preset time period of 12:00 AM to 02:00 AM and performs operation 701, After performing operations 703, 705, 707, and 709, operation 901 may be performed. In operation 901 , the processor 120 may determine again whether the second condition is satisfied based on the contents performed in operations 701 , 703 , 705 , 707 , and 709 .

10 is a diagram illustrating an example of setting the first long-term charging time period 1010 when the first condition is satisfied. According to an embodiment, an alarm may be set in the electronic device (eg, the electronic device 101 of FIG. 1 ) from the 12th to the 18th in a daily cycle. The electronic device 101 may continue in a no-input state from the time when charging of the battery 189 is started to the set alarm time for one week on a daily basis. The processor (eg, the processor 120 of FIG. 1 ) may store seven charging start times in a memory (eg, the memory 130 of FIG. 1 ) for one week in a daily cycle. The processor 120 may designate the charging start time of the 14th day, the earliest charging start time, and the 15th day, the latest charging start time as the first time 1020 and the second time 1030, respectively. When the interval between the first time 1020 and the second time 1030 is 1 hour or less, the processor 120 determines that the first reference time 1040 and the second time 30 minutes earlier than the first time 1020 are 30 minutes. A late second reference time 1050 may be set. The processor 120 may set the time period from the first reference time 1040 to the second reference time 1050 as the first long-term charging time period 1010 .

11 is a diagram illustrating an example of setting a second long-term charging time period when a second condition is satisfied. According to an embodiment, an alarm may be set in the electronic device (eg, the electronic device 101 of FIG. 1 ) from the 10th Monday to the 14th Monday in a one-week cycle. The electronic device 101 may continue in a no-input state from the time when the battery 189 starts charging to the set alarm time, respectively, for five times in a one-week cycle. The processor (eg, the processor 120 of FIG. 1 ) may store five charging start times in a memory (eg, the memory 130 of FIG. 1 ) for 5 times in a one-week cycle. The processor 120 may designate the charging start times of the earliest Monday of the twelfth week and the latest Monday of the 13th week as the third time 1120 and the fourth time 1130 , respectively. When the interval between the third time 1120 and the fourth time 1130 is 1 hour or less, the processor 120 determines that the third reference time 1140 and the fourth time are 30 minutes earlier than the third time 1120 by 30 minutes. A late fourth reference time 1150 may be set. The processor 120 may set the time period from the third reference time 1140 to the fourth reference time 1150 as the second long-term charging time period 1110 .
