Claim 10:
11. The method according to claim 1, wherein charging the secondary battery in response to the second state of health being greater than the second threshold comprises cyclically executing following processes on the secondary battery in response to the second threshold being greater than the second threshold, until a preset stop condition is satisfied:
charging the secondary battery to a preset first cut-off voltage at a constant current of a preset first rate;
charging the secondary battery to a preset charging cut-off current at a constant voltage equal to the first cut-off voltage; and
discharging the second battery to a preset second cut-off voltage at a constant current of a preset third rate;
wherein the preset stop condition includes:
a number of times that the secondary battery is discharged to the second cut-off voltage reaches a preset threshold number of times, or
the secondary battery is at the preset charging node.
