Claim 8:
9. The method for managing charging and discharging of a plurality of battery packs connected in parallel according to claim 1, wherein the managing charging and discharging of the plurality of battery packs based on a comparison result comprises:
determining, when none of the plurality of battery packs is connected to a power bus, whether a difference between the voltage value of all the battery packs and the reference voltage value is less than a first threshold, and whether a difference between the state of charge of all the battery packs and the reference state of charge is less than a second threshold; and
controlling the battery packs to sequentially connect to the power bus if the difference between the voltage value of all the battery packs and the reference voltage value is less than the first threshold, and if the difference between the state of charge of all the battery packs and the reference state of charge is less than the second threshold.
