[0082] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0083] With the diversification of electronic device usage scenarios, many users like to use electronic devices while charging. This usage causes the electronic device's battery to be under high temperature and high pressure for a long time after it is fully charged, which leads to a shortened battery life and problems such as battery bulging and swelling.

[0084] In related technologies, for situations where multiple recharges occur during a single charge, battery life is optimized by reducing the number of recharges. However, because the charge level during recharges is relatively high, the battery remains at a high voltage for an extended period. Another related technology limits the battery's charging capacity when the user activates nighttime charging mode, preventing it from reaching full charge. This method is rather simplistic and doesn't consider actual charging scenarios, thus having limitations.

[0085] For example, see Figure 1 The diagram illustrates battery capacity loss under different charge levels at the same ambient temperature. At an ambient temperature of 45 degrees Celsius, two identical batteries are maintained at 50% and 100% charge, respectively. Both batteries initially have a capacity of 100%. After 30 days at 50% charge, the battery capacity loss is 1%; after 30 days at 100% charge, the capacity loss is 5%; after 60 days at 50% charge, the capacity loss is 1.8%; and after 60 days at 100% charge, the capacity loss is 9%. Figure 1 It can be seen that, under the same ambient temperature, the higher the battery charge, the greater the battery capacity loss. Therefore, in this embodiment of the disclosure, the full charge level of the battery is adjusted according to the relationship between temperature and the full charge level to reduce battery capacity loss.

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

[0087] For example, in the driving navigation scenario, many users start navigation while driving. Since navigation consumes a lot of power, the user will choose to charge while navigating. In this case, the phone will always maintain the state of charging while navigating, thereby causing the battery of the phone to be in a high-temperature and high-voltage state for a long time, affecting the service life of the battery. By using the method provided in the embodiments of the present disclosure, the full charge capacity of the phone can be adjusted in real time according to the temperature of the battery, thereby avoiding the phone being in a high-temperature and high-voltage state for a long time.

[0088] For example, in the driving navigation scenario, many users start navigation while driving. Since navigation consumes a lot of power, the user will choose to charge while navigating. In this case, the phone will always maintain the state of charging while navigating, thereby causing the battery of the phone to be in a high-temperature and high-voltage state for a long time, affecting the service life of the battery. By using the method provided in the embodiments of the present disclosure, the full charge capacity of the phone can be adjusted in real time according to the temperature of the battery, thereby avoiding the phone being in a high-temperature and high-voltage state for a long time.

[0089] Before introducing the battery charging method provided by the embodiments of the present disclosure, the battery charging system is first described, referring to the schematic diagram of the battery charging system shown in FIG. 1. Figure 2 As shown in FIG. 1, the electronic device is connected with the charging device (Adapter). The charging device provides input power for the electronic device, that is, provides Input Current (input current). Then, through the power controller in the electronic device, a part of the input power is provided as system power to the system of the electronic device, that is, Sys Current (system current) is provided to the system, and another part of the input power is provided to the battery, that is, Charge Current (charging current) is provided to the battery. When the electronic device is fully charged (the full charge capacity is 100% by default), the battery charging path will be closed. At this time, the Charge Current is 0, and the Input Current is all provided to the system. When the Input Current is turned off, the system power consumption is provided by the battery, and the battery capacity will decrease.

[0090] Figure 3 FIG. 2 is a flowchart of a battery charging method according to an exemplary embodiment, executed by an electronic device, referring to FIG. 3. Figure 3 The method comprises the following steps:

[0091] In step S301, a first full charge capacity of a battery of the electronic device is obtained. The first full charge capacity is the current full charge capacity of the battery.

[0092] The electronic device is connected with a charging device, and the charging device is a charger.

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

[0094] In step S302, the second full charge capacity corresponding to the current temperature of the battery is obtained based on the first correspondence.

[0095] The first correspondence is the correspondence between the temperature of the battery and the full charge capacity, and the second full charge capacity is a full charge capacity more suitable for the current temperature of the battery. The second full charge capacity can be higher than the first full charge capacity, can be lower than the first full charge capacity, or can 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 electric quantity state all the time.

[0096] In step S303, the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity.

[0097] In the embodiments of the present disclosure, during the charging process, the temperature of the battery changes with the ambient temperature, the charging time, and the use of the electronic device by the user. In this case, the first full charge capacity can no longer be the most suitable full charge capacity for the current temperature of the battery. In order to increase the battery life, the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity.

[0098] In step S304, charging is performed based on the second full charge capacity.

[0099] The charging based on the second full charge capacity means that the charging process of the charging device on the electronic device is adjusted so that the full charge capacity of the battery is maintained at the second full charge capacity.

[0100] The method provided by the embodiments of the present disclosure obtains the first full charge capacity of the battery of the electronic device, then obtains the second full charge capacity according to the temperature of the battery, the second full charge capacity being a more suitable full charge capacity at the temperature, modifies the full charge capacity of the battery from the first full charge capacity to the second full charge capacity, and then charges based on the second full charge capacity. The full charge capacity of the battery is adaptively adjusted according to the temperature of the battery, so that the battery of the electronic device is prevented from being in a high temperature and high pressure state for a long time, the battery life is optimized, the battery aging is delayed, and the problems such as battery bulging and expansion caused by battery aging are further delayed.

[0101] The implementation process of steps S301-S304 can be performed multiple times, wherein the first time the process is performed, the first full charge amount is a preset amount, and starting from the second time, the first full charge amount is the second full charge amount obtained last time. The process of obtaining the first full charge amount is described below:

[0102] The first full charge amount is obtained, referring to Figure 4 , Figure 4 is a flowchart for obtaining a full charge amount according to an exemplary embodiment, executed by an electronic device, comprising the following steps:

[0103] In step S401, when the battery's charge reaches a preset amount during charging, the duration of the battery's charge at the preset amount is detected.

[0104] The preset amount is a maximum chargeable amount set in advance, for example, the preset amount is 100%, 99%, or other amounts. When the battery's charge reaches the preset amount, it means that the current charge has reached the maximum amount, and under the condition of continuing to charge, the battery's charge will not increase. At this time, the duration of the battery's charge at the preset amount is detected, and the longer the duration, the longer the battery's charge at high temperature and high capacity.

[0105] In some embodiments, when the battery's charge reaches the preset amount during charging, and the charging state is a full charge state, the duration of the battery's charge at the preset amount is detected. The full charge state means that the battery capacity has been fully charged. In the embodiments of the present disclosure, considering that the battery's charge displayed by the electronic device can be set artificially, in the case that the battery's charge reaches the preset amount, the actual charge of the battery may not have reached the preset amount, therefore, it is also necessary to determine the charging state of the battery. When the charging state is a full charge state, it means that the battery capacity has been fully charged, and at this time the battery's charge has also reached the preset amount. For example, the full charge state can be represented as FULL.

[0106] In some embodiments, when the battery's charge reaches the preset amount during charging, 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] In step S402, when the duration reaches the first preset duration, the preset amount is determined as the first full charge amount.

[0108] When the duration reaches the first preset duration, it means that the battery's charge has been maintained at the preset amount for a period of time, and the battery's charge will not increase at this time. The preset amount is determined as the first full charge amount.

[0109] In some embodiments, when the timer expires, the preset power is determined as the first full charging power.

[0110] It should be noted that in other embodiments, the time length does not reach the first preset time length, that is, the timer does not expire, and it is determined whether the charging device is disconnected from the electronic device. If not disconnected, the duration of the battery power at the preset power is continued to be detected; if disconnected, the timer is closed, the charging is stopped, and the subsequent steps are no longer performed.

[0111] The Nth first full charging power is obtained, N being an integer greater than 1: starting from the time length reaching the first preset time length, the first full charging power is obtained every second preset time length until the electronic device is disconnected from the charging device. Among them, the Nth first full charging power obtained is the (N-1)th second full charging power, the (N-1)th second full charging power is the second full charging power corresponding to the current temperature of the battery obtained based on the first correspondence relationship after obtaining the (N-1)th first full charging power, N is an integer greater than 1, and the 1st first full charging power is the preset power.

[0112] After the first full charging power is obtained for the first time and steps S302-S304 are performed, when the first full charging power is obtained for the second time, the first full charging power obtained for the second time is the second full charging power obtained for the first time, and the subsequent first full charging power is obtained in the same way as the first full charging power obtained for the second time.

[0113] Based on the above process of obtaining the first full charging power for the first time and the Nth time, the battery charging method of the embodiments of the present disclosure is:

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

[0115] In the embodiments of the present disclosure, the process of repeatedly performing the steps of obtaining the first full charging power, obtaining the second full charging power corresponding to the current temperature of the battery, modifying the full charging power of the battery from the first full charging power to the second full charging power, and charging based on the second full charging power, can adjust the full charging power of the battery in real time, 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 the aging of the battery.

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

[0117] In step S501, a first full charge capacity of a battery of the electronic device is acquired, the first full charge capacity being a current full charge capacity of the battery.

[0118] In step S502, a second full charge capacity corresponding to a current temperature of the battery is acquired based on a first correspondence relationship.

[0119] In step S503, the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity.

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

[0121] After step S503, charging is performed based on the second full charge capacity, including: charging the battery based on the relationship between the second full charge capacity and the first full charge capacity, so that the battery capacity is adjusted to the second full charge capacity. The following steps S504-S506 will explain three different charging situations.

[0122] In step S504, in the case where the second full charge capacity is less than the first full charge capacity, the battery is controlled to discharge until the battery capacity decreases to the second full charge capacity.

[0123] In the case where the second full charge capacity is less than the first full charge capacity, it indicates that the current battery capacity is high, and the battery capacity needs to be reduced, i.e., the battery is controlled to discharge until the battery capacity decreases to the second full charge capacity.

[0124] In some embodiments, the electronic device comprises a battery charging path and a system power supply path, the battery charging path being used for charging the battery, and the system power supply path being used for supplying power to the system of the electronic device. Controlling the battery to discharge until the battery capacity decreases to the second full charge capacity comprises: controlling the battery charging path and the system power supply path to be disconnected until the battery capacity decreases to the second full charge capacity, and controlling the battery charging path to remain disconnected and the system power supply path to be connected.

[0125] Controlling the battery charging path and the system power supply path to be disconnected means that the electronic device is connected with 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 capacity. The battery discharges when supplying power to the system, until the battery capacity decreases to the second full charge capacity. Controlling the battery charging path to remain disconnected and the system power supply path to be connected means that the charging device supplies power to the system, but does not charge the battery, so that the battery capacity is adjusted to the second full charge capacity.

[0126] Step S505, in the case that the second full charge capacity is greater than the first full charge capacity, control the battery to be charged until the battery capacity is raised to the second full charge capacity.

[0127] In the case that the second full charge capacity is greater than the first full charge capacity, it indicates that the current battery capacity is low, and the battery capacity needs to be raised, that is, the battery is controlled to be charged until the battery capacity is raised to the second full charge capacity.

[0128] In some embodiments, the control of the battery to be charged until the battery capacity is raised to the second full charge capacity includes: controlling the connection of the battery charging path and the system power supply path until the battery capacity is raised to the second full charge capacity, and controlling the disconnection of the battery charging path and the connection of the system power supply path.

[0129] The connection of the battery charging path and the system power supply path means that the charging device charges the battery of the electronic device and supplies power to the system of the electronic device until the battery capacity is raised to the second full charge capacity. The disconnection of the battery charging path and the connection of the system power supply path means that the charging device supplies power to the system and no longer charges the battery, so that the battery capacity is adjusted to the second full charge capacity.

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

[0131] In the case that the second full charge capacity is equal to the first full charge capacity, it indicates that the current battery capacity is appropriate, and the battery capacity does not need to be changed, that is, the charging of the battery is stopped.

[0132] In some embodiments, the stop of the charging of the battery includes: controlling the disconnection of the battery charging path and the connection of the system power supply path, that is, the charging device supplies power to the system and does not charge the battery.

[0133] It should be noted that the above charging process is described by taking the connection between the electronic device and the charging device as an example. In another embodiment, when the electronic device is disconnected from the charging device, the charging is stopped.

[0134] In the embodiments of the present disclosure, different control modes are adopted for the battery capacity in different cases, 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 capacity suitable for the current temperature of the battery, thereby avoiding the long-term high-temperature and high-pressure state of the battery of the electronic device, optimizing the battery life and delaying the aging of the battery.

[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] In step S601, a first full charge capacity of the battery and a first recharging capacity corresponding to the first full charge capacity are obtained.

[0137] The electronic device performs recharging during the charging process. When the full charge capacity of the battery changes, the recharging capacity of the battery also changes. The first recharging capacity is the recharging capacity when the full charge capacity of the electronic device is the first full charge capacity. The first full charge capacity is obtained each time, and the first recharging 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 recharging capacity is 98% at this time.

[0138] In step S602, a second full charge capacity and a second recharging capacity corresponding to the current temperature of the battery are obtained based on the first correspondence relationship and the second correspondence relationship.

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

[0140] For example, the first correspondence relationship and the second correspondence relationship are as shown in Table 1 below:

[0141] Table 1

[0142] Temperature of the battery Full charge Recharge 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 correspondence relationship in Table 1 is an example. In another embodiment, other correspondence relationships can be set.

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

[0145] In step S603, the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity, and the recharging capacity of the battery is modified from the first recharging capacity to the second recharging capacity.

[0146] In step S604, charging is performed based on the second full charge capacity and the second recharging capacity.

[0147] Charging based on the second full charge capacity and the second recharging capacity includes any of the following cases:

[0148] In a case where the second full charge capacity is less than the first full charge capacity, the charging path between the electronic device and the charging device is controlled to be disconnected until the battery capacity decreases to the second full charge capacity, the battery charging path is controlled to be disconnected and the system power supply path is controlled to be connected, when the battery capacity decreases from the second full charge capacity to the second full charge capacity, the battery charging path is controlled to be connected and the system power supply path is controlled to be connected until the battery capacity increases to the second full charge capacity, and then the battery is charged again when the battery capacity decreases to the second full charge capacity again.

[0149] In a case where the second full charge capacity is greater than the first full charge capacity, the charging path is controlled to be connected until the battery capacity increases to the second full charge capacity, the battery charging path is controlled to be disconnected and the system power supply path is controlled to be connected, when the battery capacity decreases from the second full charge capacity to the second full charge capacity, the battery charging path is controlled to be connected and the system power supply path is controlled to be connected until the battery capacity increases to the second full charge capacity, and then the battery is charged again when the battery capacity decreases to the second full charge capacity again.

[0150] In a case where the second full charge capacity is equal to the first full charge capacity, the battery charging path is controlled to be disconnected and the system power supply path is controlled to be connected, when the battery capacity decreases from the second full charge capacity to the second full charge capacity, the battery charging path is controlled to be connected and the system power supply path is controlled to be connected until the battery capacity increases to the second full charge capacity, and then the battery is charged again when the battery capacity decreases to the second full charge capacity again.

[0151] In the embodiments of the present disclosure, the first full charge capacity and the first full charge capacity are obtained, and then the second full charge capacity and the second full charge capacity are obtained according to the temperature of the battery, the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity, the full charge capacity of the battery is modified from the first full charge capacity to the second full charge capacity, and then the battery is charged based on the second full charge capacity and the second full charge capacity. The full charge capacity and the full charge capacity of the battery are adaptively adjusted according to the temperature of the battery, so as to avoid the battery of the electronic device being in a high temperature and high pressure state for a long time, optimize the battery life, delay the battery aging, and further delay the problems such as battery bulging and expansion caused by battery aging.

[0154] At step S701, a first full charging amount corresponding to a first recharging amount is obtained.

[0155] At step S702, a second recharging amount corresponding to a current temperature of the battery is obtained based on a second correspondence relationship.

[0156] At step S703, the recharging amount of the battery is modified from the first recharging amount to the second recharging amount.

[0157] The embodiments of steps S701-S703 are described above with reference to steps S601-S603, and will not be repeated here.

[0159] The charging based on the second recharging amount includes: after the battery power is reduced from the current full charging amount to the second recharging amount, the battery is controlled to be charged until the battery power is increased to the current full charging amount of the battery.

[0160] In some embodiments, after the battery power is reduced from the current full charging amount to the second recharging amount, the battery charging path and the system power supply path are connected until the battery power is increased to the current full charging amount, and then the battery is charged again when the battery power is reduced to the second recharging amount again.

[0176] 2. Run the full charge capacity optimization algorithm in a loop.

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

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

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

[0180] 6. Determine whether the first full charge capacity Soc_now is equal to the second full charge capacity Soc_new. If yes, based on the algorithm cycle time t, proceed to step 2 when starting the next algorithm cycle. If no, proceed to step 7.

[0181] 7. Run the full charge algorithm execution function module, i.e. execute the full charge algorithm execution function module shown in Figure 9The battery charging process shown, after allowing the full charging algorithm to perform the function module, based on the algorithm cycle time t, when the next algorithm cycle is started, step 2 is performed.

[0182] Referring to Figure 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, step 2 is performed. If the second full charge capacity is less than the first full charge capacity, step 4 is performed.
