Claim 9:
10. The method for managing charging and discharging of a plurality of battery packs connected in parallel according to claim 9, wherein the managing charging and discharging of the plurality of battery packs based on a comparison result further comprises:
determining, when at least one battery pack is already connected to the power bus and the battery pack is in a charging state, whether a difference between the voltage value of battery packs not connected to the power bus and the reference voltage value is within a first range, and whether a difference between the state of charge of the battery packs not connected to the power bus and the reference state of charge is within a second range; and
controlling the battery packs to sequentially connect to the power bus if the difference between the voltage value of all the battery packs not connected to the power bus and the reference voltage value is within the first range, and if the difference between the state of charge of all the battery packs not connected to the power bus and the reference state of charge is within the second range.
