SYSTEM, PROGRAM, AND MANAGEMENT METHOD

Provided is a system comprising: a management unit that manages a plurality of battery packs, which are connected in parallel to a bus to which a power generation unit and a load are connected, to have the plurality of battery packs being alternately discharged so that a voltage difference between a battery pack with a highest voltage and a battery pack with a lowest voltage among the plurality of battery packs is not greater than a voltage threshold. Provided is a management method of a plurality of battery packs performed by a computer, the plurality of battery packs being connected in parallel to a bus to which a power generation unit and a load are connected, the method comprises: managing the plurality of battery packs to have the plurality of battery packs being alternately discharged so that a voltage difference between a battery pack with a highest voltage and a battery pack with a lowest voltage among the plurality of battery packs is not greater than a voltage threshold.
