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.
