Abstract

To activate a battery system at an early stage.SOLUTION: A battery system 1 comprises: battery units 10 and 20 which are connected in parallel; battery unit voltage detectors 14 and 24 which detect voltage values of the battery units 10 and 20; a plurality of unit relays 15 and 25 connected in series to the plurality of battery units 10 and 20; and a balance circuit 40. The battery units 10 and 20 each include: a plurality of electric cells (a) connected in series; electric cell voltage detectors 12 and 22; and equalizers 13 and 23 for equalizing residual capacities of the plurality of electric cells (a). The balance circuit 40 has a resistor 41. One end of the balance circuit 40 is connected to a node between the battery unit 10 and the unit relay 15 which are connected in series. The other end of the balance circuit 40 is connected to a node between the battery unit 20 and the unit relay 25 which are connected in series.SELECTED DRAWING: Figure 1
