Embodiment 1
[0086] refer to figure 2 .
[0087] S110: Acquire a parameter value of the battery, where the parameter value is used to determine whether the battery is charged with a first current.
[0088] This step is specifically: first obtain the parameter value of the battery, for example, obtain the actual full capacity of the battery (full charge capacity). The actual full capacity of the battery can be obtained from the battery via the bus (SMBUS). In addition, the actual full capacity can be obtained by measuring the battery through the bus, and other methods well known to those skilled in the art can also be used.
[0089] S120: Invoking standard information for judging whether the battery is charged with the first current.
[0090] This step is specifically: call the design capacity of the battery (Design capacity), the design capacity can be obtained from the battery through the bus (SMBUS), because the design capacity is set when the battery leaves the factory, for example,...
Embodiment 2
[0100] In this embodiment, the same steps as those in Embodiment 1 will not be repeated, and the difference is:
[0101] The parameter value includes the number of service cycles of the battery, because the capacity of the battery will decrease with the number of service cycles of the battery, so the first current can also be determined according to the number of cycles that the battery has been used; the standard information includes The number of preset cycles, the number of preset cycles is the number of battery service cycles when charging with the charging current corresponding to the preset standard; for example, the number of preset cycles is 50, which means that when the number of times of use is less than 50, the charging current The charging current corresponding to the preset standard of the factory-set battery is, for example, greater than 0.7C; when the battery has been used for more than 50 times, the first current may be 0.35C.

Embodiment 3
[0105] This embodiment includes the method described in embodiment one, and is different from embodiment one in addition:
[0106] Before the step of acquiring the parameter value of the battery, the method further includes: discharging the battery.
[0107] In this embodiment, it is specifically: when the battery condition is not good, for example, the actual full capacity is less than 50% of the design capacity, prompt and ask the user whether to select the discharge mode to restore the battery capacity, and when the user agrees to restore the battery capacity, remind The user inserts and does not remove the battery until the recovery process is complete. When the discharge mode is selected and the battery is detected, a command is sent to discharge the battery with a small current. By using the method of discharging the battery, it is possible to restore the battery whose capacity has been reduced to increase its capacity. The step of battery discharge can be done after f...
