[SOLVING MEANS] A battery system includes a first battery (10) and a second battery (20) connected in parallel and performing charge and discharge. A first relay (SMR-B1) is switched between an ON state in which the charge and discharge of the first battery are allowed and an OFF state in which the charge and discharge of the first battery are prohibited. A second relay (SMR-B2) is switched between an ON state in which the charge and discharge of the second battery are allowed and an OFF state in which the charge and discharge of the second battery are prohibited. A controller (41) controls the ON state and the OFF state of each of the first relay and the second relay. The controller also changes the order in which the first relay and the second relay are switched to the ON state, in performing the charge and discharge of the first battery and the second battery.",
