Claim 10:
11. The method for managing charging and discharging of a plurality of battery packs connected in parallel according to claim 10, 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 packs not connected to the power bus are in a discharging state, whether a difference between the reference voltage value and the voltage value of all the battery packs not connected to the power bus is within a third range, and whether a difference between the reference state of charge and the state of charge of all the battery packs not connected to the power bus is within a fourth range; and
controlling the battery packs to sequentially connect to the power bus if the difference between the reference voltage value and the voltage value of all the battery packs not connected to the power bus is within the third range, and if the difference between the reference state of charge and the state of charge of all the battery packs not connected to the power bus is within the fourth range.
