1. A control method for a plurality of power storage apparatuses connected in parallel to each other via respective switches, the control method comprising:
controlling the switches,
wherein the controlling the switches includes:
in response to receiving an instruction to charge or discharge the plurality of power storage apparatuses, based on respective voltage values of the plurality of power storage apparatuses and respective resistance values of conductive paths of the plurality of power storage apparatuses, only turn on a switch of at least one of the plurality of power storage apparatuses having a conductive path with a smallest resistance value to start charging or discharging the at least one of the plurality of power storage apparatuses.
