Claim 17:
18. The device according to claim 16, wherein the computer program instructions further cause the processor to:
set an overcharge protection voltage as a lithium-supplementing voltage, wherein the lithium-supplementing voltage is a charging cut-off voltage corresponding to a charging node where the secondary battery is at;
control to charge the secondary battery to the lithium-supplementing voltage at a constant current of a preset first rate;
control to charge the secondary battery to a preset charging cut-off current at a constant voltage equal to the lithium-supplementing voltage; and
control to discharge the second battery to a preset cut-off voltage at a constant current of a preset second rate.
