[0082] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0083] With the diversification of usage scenarios of electronic devices, many users like to use electronic devices while charging. This usage method causes the batteries of electronic devices to be in high temperature and high pressure conditions for a long time after being fully charged, which shortens the battery life and causes problems such as battery bulging and expansion.

[0084] In the related art, in case of multiple recharges during a single charge, the battery life is optimized by reducing the number of recharges. In this way, the battery will still be at a high voltage for a long time due to the high power during recharge. In another related art, when the user turns on the night charging mode, the battery charging power is limited so that the battery cannot be charged to full charge. This method is relatively simple and does not take into account the actual charging scenario, so it has limitations.

[0085] For example, see Figure 1 The schematic diagram of battery capacity loss under different power levels at the same ambient temperature is shown in the figure. At an ambient temperature of 45 degrees, the power levels of two identical batteries are maintained at 50% and 100% respectively. The initial capacity of both batteries is 100%. When the battery is maintained at 50% power for 30 days, the battery capacity loses 1%. When the battery is maintained at 100% power for 30 days, the battery capacity loses 5%. When the battery is maintained at 50% power for 60 days, the battery capacity loses 1.8%. When the battery is maintained at 100% power for 60 days, the battery capacity loses 9%. Figure 1 It can be seen that at the same ambient temperature, the higher the battery charge, the greater the battery capacity loss. Therefore, in the embodiment of the present disclosure, the full charge of the battery is adjusted according to the relationship between the temperature and the full charge of the battery to reduce the loss of the battery capacity.

[0086] The battery charging method provided by the embodiments of the present disclosure can be applied to a variety of scenarios.

[0087] For example, in a driving navigation scenario, many users will turn on navigation while driving. Since navigation consumes a lot of power, users will choose to navigate while charging. In this case, the mobile phone will always maintain the state of navigating while charging, which will cause the battery of the mobile phone to be in a high temperature and high pressure state for a long time, affecting the battery life. By adopting the method provided in the embodiment of the present disclosure, the full charge of the mobile phone can be adjusted in real time according to the temperature of the battery, so as to avoid the mobile phone being in a high power state for a long time, that is, to avoid the battery being in a high temperature and high pressure state for a long time.

[0088] For another example, in a gaming scenario, the game consumes a lot of power, and many users will play games while charging. In this case, the mobile phone battery will maintain high temperature and high pressure after being fully charged, affecting the battery life. By adopting the method provided in the embodiment of the present disclosure, the full charge capacity of the mobile phone can be adjusted in real time according to the temperature of the battery, thereby preventing the mobile phone from being in a high power state for a long time, that is, preventing the battery from being in a high temperature and high pressure state for a long time.

[0089] Before introducing the battery charging method provided by the embodiment of the present disclosure, the battery charging system is first described. Figure 2 In the schematic diagram of the battery charging system shown, the electronic device is connected to the charging device (Adapter), and the charging device provides input power to the electronic device, that is, provides Input Current, and then through the power controller in the electronic device, a part of the input power is provided to the system of the electronic device as system power, that is, Sys Current is provided to the system, and another part of the input power is provided to the battery, that is, Charge Current is provided to the battery. When the electronic device is fully charged (the default full charge is 100%), the battery charging path will be closed, and the Charge Current is 0 at this time, and the Input Current is all provided to the system. When the Input Current is closed, the system power consumption is provided by the battery, and the battery power will decrease.

[0090] Figure 3 is a flowchart of a battery charging method according to an exemplary embodiment, which is executed by an electronic device, see Figure 3 , the method comprises the following steps:

[0091] Step S301, obtaining a first fully charged capacity of a battery of an electronic device, where the first fully charged capacity is a current fully charged capacity of the battery.

[0092] The electronic device is connected to a charging device, which is a charger.

[0093] In the embodiment of the present disclosure, when the electronic device is connected to the charging device, that is, when the electronic device is continuously charged, the current full charge of the electronic device is obtained, that is, the first full charge is obtained, and the full charge of the battery is the maximum charge of the battery during the charging process. For example, the first full charge is 100%, 99%, 98% or other charges.

[0094] Step S302: Based on the first corresponding relationship, obtain a second full charge capacity corresponding to the current temperature of the battery.

[0095] The first corresponding relationship is the corresponding relationship between the battery temperature and the full charge capacity, and the second full charge capacity is a full charge capacity that is more suitable for the current temperature of the battery. The second full charge capacity may be higher than the first full charge capacity, may be lower than the first full charge capacity, or may be the same as the first full charge capacity. For a certain temperature of the battery, when the full charge capacity of the battery is maintained at the full charge capacity corresponding to the temperature, the battery can be prevented from being in a high charge state all the time.

[0096] Step S303, modifying the full charge capacity of the battery from the first full charge capacity to the second full charge capacity.

[0097] In the disclosed embodiment, during the charging process, the temperature of the battery will change with the ambient temperature, charging time, and user usage of the electronic device. In this case, the first full charge capacity may no longer be the most suitable full charge capacity for the current temperature of the battery. In order to increase the battery life, the battery's full charge capacity is changed from the first full charge capacity to the second full charge capacity.

[0098] Step S304, charging based on the second full charge capacity.

[0099] Charging based on the second full charge capacity refers to: adjusting the charging process of the electronic device by the charging device so that the full charge capacity of the battery is maintained at the second full charge capacity.

[0100] The method provided by the embodiment of the present disclosure obtains the current first full charge capacity of the battery of the electronic device, and then obtains the second full charge capacity according to the temperature of the battery, the second full charge capacity being a full charge capacity that is more suitable for the temperature, and the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity, and then charged based on the second full charge capacity, and the full charge capacity of the battery is adaptively adjusted according to the temperature of the battery, thereby avoiding the battery of the electronic device being in a state of high temperature and high pressure for a long time, optimizing the battery life, delaying battery aging, and further delaying problems such as battery bulging and expansion caused by battery aging.

[0101] The implementation process of the above steps S301-S304 can be executed repeatedly. When the process is executed for the first time, the first full charge capacity is the preset power. From the second time onwards, the first full charge capacity is the second full charge capacity obtained last time. The process of obtaining the first full charge capacity is described below:

[0102] To obtain the full charge capacity for the first time, see Figure 4 , Figure 4 The flowchart of obtaining the full charge capacity according to an exemplary embodiment is executed by an electronic device and includes the following steps:

[0103] Step S401, when the power level of the battery reaches a preset power level during the charging process, the duration of the battery power remaining at the preset power level is detected.

[0104] The preset power is the maximum chargeable power that is preset, for example, the preset power is 100%, 99% or other power. When the battery power reaches the preset power, it means that it has been charged to the maximum power. If charging continues, the battery power will not increase. At this time, the duration of the battery power at the preset power is detected. The longer the duration is, the longer the battery can last at high temperature and high power.

[0105] In some embodiments, when the battery power reaches a preset power level during the charging process and the charging state is a fully charged state, the duration of the battery power remaining at the preset power level is detected. The fully charged state means that the battery capacity is fully charged. In the disclosed embodiments, considering that the battery power level displayed by the electronic device can be manually set, when the battery power level reaches a preset power level, the actual battery power level may not reach the preset power level. Therefore, it is also necessary to judge the battery charging state. When the charging state is a fully charged state, it means that the battery capacity is fully charged, and the battery power level has also reached the preset power level. For example, the fully charged state can be expressed as FULL.

[0106] In some embodiments, when the power of the battery reaches a preset power during the charging process, a timer is started, and the timing duration of the timer is a first preset duration. The first preset duration is a preset duration, for example, the first preset duration is 10 minutes, 20 minutes or other durations.

[0107] Step S402, when the duration reaches a first preset duration, the preset power is determined as a first full charge.

[0108] When the time reaches the first preset time, it means that the battery power has been maintained at the preset power for a period of time and the battery power will not increase any more. At this time, the preset power is determined as the first full charge.

[0109] In some embodiments, when the timer times out, the preset power level is determined as the first full charge level.

[0110] It should be noted that, in other embodiments, if the duration does not reach the first preset duration, that is, the timer has not timed out, it is determined whether the charging device and the electronic device are disconnected. If they are not disconnected, the duration for which the battery power remains at the preset power level is continued to be detected; if they are disconnected, the timer is turned off, charging is stopped, and subsequent steps are no longer executed.

[0111] The first full charge is obtained for the Nth time, where N is an integer greater than 1: starting from the time when the first preset time is reached, the first full charge is obtained every second preset time until the electronic device is disconnected from the charging device. The Nth first full charge obtained is the N-1th second full charge, and the N-1th second full charge is the second full charge corresponding to the current temperature of the battery obtained based on the first corresponding relationship after the N-1th first full charge is obtained, N is an integer greater than 1, and the first first full charge is the preset power.

[0112] After the first full charge capacity is obtained for the first time and steps S302-S304 are executed, when the first full charge capacity is obtained for the second time, the first full charge capacity obtained for the second time is the second full charge capacity obtained for the first time, and the first full charge capacity is obtained thereafter in the same manner as the first full charge capacity is obtained for the second time.

[0113] Based on the above process of obtaining the first full charge capacity for the first time and the Nth time, the battery charging method of the embodiment of the present disclosure is as follows:

[0114] When the battery power reaches the preset power during the charging process, the duration of the battery power at the preset power is detected. When the duration reaches the first preset duration, the preset power is determined as the first full charge, and steps S302-S304 are executed. Then, when the next cycle starts, the second full charge obtained last time is used as the first full charge during this cycle, and steps S302-S304 are executed again until the electronic device is disconnected from the charging device. Among them, the time point at which each cycle starts from the second time is a time point that is N-1 second preset durations apart from the first time point, and the first time point is the time point when the duration reaches the first preset duration.

[0115] In the disclosed embodiment, the first full charge capacity is obtained repeatedly, the second full charge capacity corresponding to the current temperature of the battery is obtained, the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity, and the charging process is performed based on the second full charge capacity. The full charge capacity of the battery can be adjusted in real time, thereby avoiding the battery of the electronic device being in a state of high temperature and high pressure for a long time, optimizing the battery life, and delaying battery aging.

[0116] Figure 5is a flowchart of another battery charging method according to an exemplary embodiment, which is executed by an electronic device, see Figure 5 , the method comprises the following steps:

[0117] Step S501, obtaining a first fully charged capacity of a battery of an electronic device, where the first fully charged capacity is a current fully charged capacity of the battery.

[0118] Step S502: Based on the first corresponding relationship, obtain a second full charge capacity corresponding to the current temperature of the battery.

[0119] Step S503, modifying the full charge capacity of the battery from the first full charge capacity to the second full charge capacity.

[0120] The implementation of steps S501-S503 is the same as the implementation of steps S301-S303 described above, and will not be repeated here.

[0121] After step S503, charging based on the second full charge includes: charging the battery based on the relationship between the second full charge and the first full charge, so that the battery power is adjusted to the second full charge. Three different charging situations are described below through steps S504-S506.

[0122] Step S504, when the second full charge capacity is less than the first full charge capacity, control the battery to discharge until the battery power drops to the second full charge capacity.

[0123] When the second full charge capacity is less than the first full charge capacity, it indicates that the current charge of the battery is high and the charge of the battery needs to be reduced, that is, the battery is controlled to discharge until the charge of the battery is reduced to the second full charge capacity.

[0124] In some embodiments, the electronic device includes a battery charging path and a system power supply path, the battery charging path is used to charge the battery, and the system power supply path is used to power the system of the electronic device. Controlling the battery to discharge until the battery power drops to a second full charge includes: controlling the battery charging path and the system power supply path to be disconnected until the battery power drops to the second full charge, controlling the battery charging path to remain disconnected and the system power supply path to be connected.

[0125] The battery charging path and the system power supply path are controlled to be disconnected, that is, the electronic device is connected to the charging device, but the charging device no longer supplies power to the electronic device, and the battery of the electronic device needs to supply power to the system of the electronic device, consuming the battery power. When the battery supplies power to the system, the battery discharges until the battery power drops to the second full charge capacity. The battery charging path is controlled to remain disconnected and the system power supply path is connected, that is, the charging device supplies power to the system without charging the battery, so that the battery power is adjusted to the second full charge capacity.

[0126] Step S505, when the second full charge capacity is greater than the first full charge capacity, control the battery to charge until the battery power reaches the second full charge capacity.

[0127] When the second full charge capacity is greater than the first full charge capacity, it indicates that the current charge of the battery is low and the charge of the battery needs to be increased, that is, the battery charging is controlled until the charge of the battery is increased to the second full charge capacity.

[0128] In some embodiments, controlling the battery charging until the battery charge reaches a second full charge level includes: controlling the battery charging path and the system power supply path to be connected until the battery charge reaches the second full charge level, and controlling the battery charging path to be disconnected and the system power supply path to remain connected.

[0129] The battery charging path and the system power supply path are controlled to be connected, that is, the charging device charges the battery of the electronic device and supplies power to the system of the electronic device until the battery power reaches the second full charge level. The battery charging path is controlled to be disconnected and the system power supply path remains connected, that is, the charging device supplies power to the system but no longer charges the battery, so that the battery power is adjusted to the second full charge level.

[0130] Step S506, when the second full charge capacity is equal to the first full charge capacity, stop charging the battery.

[0131] When the second full charge capacity is equal to the first full charge capacity, it indicates that the current charge of the battery is just right and there is no need to change the charge of the battery, that is, charging of the battery is stopped.

[0132] In some embodiments, stopping charging the battery includes: controlling the battery charging path to be disconnected and the system power supply path to be connected, that is, the charging device supplies power to the system instead of charging the battery.

[0133] It should be noted that the above charging process is described by taking the electronic device and the charging device as an example in which the electronic device and the charging device remain connected. In another embodiment, when the electronic device and the charging device are disconnected, charging is stopped.

[0134] In the disclosed embodiments, different control methods are adopted according to the battery power in different situations, so that the full charge capacity of the battery is adjusted to the second full charge capacity, that is, the full charge capacity of the battery is adjusted to the power suitable for the current temperature of the battery, thereby avoiding the battery of the electronic device being in a high temperature and high pressure state for a long time, optimizing the battery life, and delaying battery aging.

[0135] Figure 6 is a flowchart of another battery charging method according to an exemplary embodiment, which is executed by an electronic device, see Figure 6 , the method comprises the following steps:

[0136] Step S601, obtaining a first full charge capacity of a battery and a first recharge capacity corresponding to the first full charge capacity.

[0137] During the charging process, the electronic device will be recharged. When the full charge capacity of the battery changes, the recharge capacity of the battery will also change. Among them, the first recharge capacity is the recharge capacity when the full charge capacity of the electronic device is the first full charge capacity. Each time the first full charge capacity is obtained, the first recharge capacity corresponding to the first full charge capacity is obtained. For example, the first full charge capacity obtained for the first time is 100%, and the first recharge capacity is 98% at this time.

[0138] Step S602: Based on the first corresponding relationship and the second corresponding relationship, obtain a second full charge capacity and a second recharge capacity corresponding to the current temperature of the battery.

[0139] The second corresponding relationship is the corresponding relationship between the battery temperature and the recharge amount. The second recharge amount is a recharge amount that is more suitable for the current temperature of the battery. The second recharge amount may be higher than the first recharge amount, may be lower than the first recharge amount, or may be the same as the first recharge amount.

[0140] For example, the first corresponding relationship and the second corresponding relationship are shown in the following Table 1:

[0141] Table 1

[0142] Battery temperature Full charge Recharge capacity Less than or equal to 40 degrees 100％ 98％ Greater than 40 degrees and less than or equal to 42 degrees 90％ 88％ Greater than 42 degrees and less than or equal to 44 degrees 80％ 78％ Greater than 44 degrees and less than or equal to 46 degrees 70％ 68％ Greater than 46 degrees 60％ 58％

[0143] The corresponding relationship in Table 1 is an example, and in another embodiment, other corresponding relationships may be set.

[0144] It should be noted that Table 1 is an example. In Table 1, the recharge amount changes with the change of the full charge amount. In another embodiment, the recharge amount only needs to be less than the full charge amount and does not necessarily need to change with the change of the full charge amount. For example, when the battery temperature is less than or equal to 40 degrees, the full charge amount is 100%, when the battery temperature is greater than 40 degrees and less than or equal to 41 degrees, the full charge amount is 95%, and when the battery temperature is less than or equal to 41 degrees, the recharge amount is 90%.

[0145] Step S603, modifying the full charge capacity of the battery from the first full charge capacity to the second full charge capacity, and modifying the recharge capacity of the battery from the first recharge capacity to the second recharge capacity.

[0146] Step S604: charging based on the second full charge amount and the second recharge amount.

[0147] Charging based on the second full charge amount and the second recharge amount includes any of the following situations:

[0148] When the second full charge amount is less than the first full charge amount, the charging path between the electronic device and the charging device is controlled to be disconnected until the battery power drops to the second full charge amount, and the battery charging path is controlled to be disconnected and the system power supply path is connected. When the battery power drops from the second full charge amount to the second re-charge amount, the battery charging path is controlled to be connected and the system power supply path is connected until the battery power increases to the second full charge amount. Then, after the battery power drops to the second re-charge amount again, the battery is charged again.

[0149] When the second full charge amount is greater than the first full charge amount, the charging path is controlled to be connected until the battery power increases to the second full charge amount, the battery charging path is controlled to be disconnected and the system power supply path is connected, and when the battery power decreases from the second full charge amount to the second re-charge amount, the battery charging path is controlled to be connected and the system power supply path is connected until the battery power increases to the second full charge amount, and then the battery is charged again after the battery power decreases to the second re-charge amount again.

[0150] When the second full charge amount is equal to the first full charge amount, the battery charging path is controlled to be disconnected and the system power supply path is connected. When the battery power decreases from the second full charge amount to the second re-charge amount, the battery charging path is controlled to be connected and the system power supply path is connected until the battery power increases to the second full charge amount. Then, after the battery power decreases to the second re-charge amount again, the battery is charged again.

[0151] In the disclosed embodiment, a first full charge capacity and a first recharge capacity are obtained, and then according to the temperature of the battery, a second full charge capacity and a second recharge capacity are obtained, the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity, and the recharge capacity of the battery is modified from the first recharge capacity to the second recharge capacity, and then charging is performed based on the second full charge capacity and the second recharge capacity, and the full charge capacity and the recharge capacity of the battery are adaptively adjusted according to the temperature of the battery, thereby avoiding that the battery of the electronic device is in a state of high temperature and high pressure for a long time, optimizing the battery life, delaying battery aging, and further delaying problems such as battery bulging and expansion caused by battery aging.

[0152] Above Figure 6 The illustrated embodiment illustrates the case where the battery is charged according to the full charge capacity and the recharge capacity of the battery. In another embodiment, the battery may be charged according to the recharge capacity.

[0153] Figure 7 is a flowchart of another battery charging method according to an exemplary embodiment, which is executed by an electronic device, see Figure 7 , the method comprises the following steps:

[0154] Step S701, obtaining a first recharge capacity corresponding to a first full charge capacity.

[0155] Step S702: Based on the second corresponding relationship, obtain a second recharge capacity corresponding to the current temperature of the battery.

[0156] Step S703, modifying the recharge amount of the battery from the first recharge amount to the second recharge amount.

[0157] The implementation of steps S701-S703 refers to the above steps S601-S603, which will not be repeated here.

[0158] Step S704: charging based on the second recharge amount.

[0159] Charging based on the second recharge amount includes: when the battery power decreases from the current full charge amount to the second recharge amount, controlling the battery to charge until the battery power increases to the current full charge amount of the battery. The current full charge amount of the battery is the full charge amount corresponding to the temperature of the battery.

[0160] In some embodiments, when the battery power level decreases from the current full charge level to the second recharge level, the battery charging path and the system power supply path are controlled to be connected until the battery power level increases to the current full charge level, and then the battery is charged again after the battery power level decreases to the second recharge level again.

[0161] In the disclosed embodiment, when the battery is recharged, the recharge amount is determined according to the current temperature of the battery, that is, the recharge amount of the battery is adaptively adjusted according to the temperature of the battery, thereby avoiding exposing the battery of the electronic device to a high temperature and high pressure state for a long time, optimizing the battery life, delaying battery aging, and further delaying problems such as battery bulging and expansion caused by battery aging.

[0162] The battery charging method shown in the above embodiment can be divided into a full charge capacity detection process, a full charge capacity adjustment process and a battery charging process. Figure 8-10 The illustrated embodiment illustrates these three processes.

[0163] Figure 8 is a schematic diagram showing a full charge monitoring process according to an exemplary embodiment, see Figure 8 , the full charge monitoring process includes the following steps:

[0164] 1. Start charging, that is, connect the electronic device to the charger.

[0165] 2. Detect whether the battery of the electronic device is fully charged, that is, detect whether the battery charge reaches a preset charge (100%). If the battery charge is not fully charged, execute step 1; if the battery charge is fully charged, execute step 3.

[0166] 3. Start the timer.

[0169] 6. Stop charging and turn off the timer.

[0170] 7. Keep the charger in place and fully charged.

[0171] It should be noted that, during the execution of steps 5-7, it is also detected whether the timer has timed out. If the timer has timed out, step 8 is executed.

[0172] 8. Start the full charge optimization algorithm, that is, execute Figure 8 The full charge adjustment process is shown.

[0173] See also Fig. 9 , the full charge adjustment process includes the following steps:

[0174] 1. Set the algorithm cycle time to t, the current first full charge capacity Soc_now to 100%, and the current first recharge capacity to 98%.

[0175] The algorithm cycle time t is the second preset time length mentioned above.

[0176] 2. The full charge capacity optimization algorithm runs in a cycle.

[0177] 3. Check whether the charger is in place. If the charger is not in place, go to step 4. If the charger is in place, go to step 5.

[0178] 4. Exit the power optimization algorithm loop, restore the battery's full charge to 100%, and stop charging.

[0179] 5. Read the battery temperature T_battery, and determine the second full charge capacity Soc_new and the second recharge capacity Soc_recharge according to the temperature.

[0180] 6. Determine whether the first full charge capacity Soc_now is equal to the second full charge capacity Soc_new. If so, based on the algorithm cycle time t, execute step 2 at the beginning of the next algorithm cycle. If not, execute step 7.

[0181] 7. Run the full charge algorithm execution function module, that is, execute Fig. 9The battery charging process shown, after allowing the full charge algorithm to execute the functional module, based on the algorithm cycle time t, when starting the next algorithm cycle, execute step 2.

[0182] See also Fig.10 , the battery charging process includes the following steps:

[0183] 1. Determine whether the second full charge capacity is greater than the first full charge capacity. If the second full charge capacity is greater than the first full charge capacity, execute step 2; if the second full charge capacity is less than the first full charge capacity, execute step 4.

[0184] 2. Change the full charge capacity of the battery from the first full charge capacity to the second full charge capacity, and change the recharge capacity of the battery from the first recharge capacity to the second recharge capacity.

[0185] 3. Start charging the battery until the battery power reaches the second full charge capacity, and then stop charging the battery.

[0186] The implementation of step 3 is the same as the implementation of step S505 in the above embodiment.

[0187] 4. Change the full charge capacity of the battery from the first full charge capacity to the second full charge capacity, and change the recharge capacity of the battery from the first recharge capacity to the second recharge capacity.

[0188] 5. Turn off the input current and the battery will power the system until the battery power drops to the second full charge, then turn on the input current.

[0189] The implementation of step 5 is similar to the implementation of step S504 in the above embodiment.
