Abstract
A battery system includes a plurality of battery packs connected in parallel each including a switch and a battery connected to the switch in series and a battery state determining unit determining a state of the battery. The battery state determining unit includes a disconnection determining unit controlling disconnection of the switch and a switch controller controlling open and close of the switch in accordance with a result of determining the state. The disconnection determining unit calculates allowable stop and demanded stop periods of the battery packs on the basis of the past data, season data, and allowable currents of the batteries and transmits data to the switch controller when the demanded stop period is smaller than the allowable stop period, and the switch controller makes the switch in an open state.
