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