  • Patent number: 8394519
    Abstract: A battery system includes a plurality of electric rechargeable cells which are stacked in a row and conductive members which electrically connect the electric rechargeable cells together. The electric rechargeable cells each has a gas exhaust port, and a positive electrode terminal and a negative electrode terminal which are disposed in such a manner as to hold the gas exhaust port therebetween. The battery system includes 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 them and on which the conductive members are provided, and a voltage control circuit which is attached to an outer surface side of the partition holding member in a position which confronts the gas exhaust member and controls voltages of the electric rechargeable cells.

  • Patent number: 7261974
    Abstract: A battery power supply system (1) for suppressing the overall temperature variation of a plurality of battery module groups (61 to 65) includes a box (2) having a cooling air inlet (3) on one end face and a suction fan (4) within a section at the other end, and a battery assembly (5) installed in an intermediate section within the box (2). The battery assembly (5) includes a plurality of battery module groups (61 to 65). Each of the battery module groups (61 to 65) includes a plurality of rod-shaped battery modules (7). When a gap between outer peripheral faces of two adjacent rod-shaped battery modules (7) of the first battery module group (61), which is closest to the cooling air inlet (3), is a, and a gap between the outer peripheral face of the rod-shaped battery modules (7) of the first battery module group (61) and the outer peripheral face of the adjacent rod-shaped battery modules (7) of the second battery module group (62) is b, the ratio a/b of the gaps a and b is set so that 1.0<a/b?2.0.
