Patent ID: 8394519

Claim:
A battery system, comprising: a plurality of electric rechargeable cells which are stacked in a row, the electric rechargeable cells each having a gas exhaust port, a positive electrode terminal and a negative electrode terminal, the positive and negative electrode terminals being disposed on upper surfaces of the plurality of electric rechargeable cells such that the gas exhaust port is disposed therebetween; a gas exhaust member connected to the gas exhaust ports; a partition holding member which establishes partitions between the gas exhaust member and the positive electrode terminals and the negative electrode terminals in such a manner as to cover the gas exhaust member and the positive electrode terminals and the negative electrode terminals; conductive members which electrically connect the electric rechargeable cells together, the conductive member being provided on the partition holding member; and a voltage control circuit which controls voltages of the electric rechargeable cells, the voltage control circuit being attached to an outer surface side of the partition holding member in a position which confronts the gas exhaust member.
