Abstract
A battery pack apparatus is configured with a battery pack composed of a plurality of rechargeable batteries arranged in parallel with cooling medium passages formed therebetween, and a cross flow fan which faces a distribution space formed adjacent to one side of the battery pack to supply or discharge cooling medium with respect to each of the cooling medium passages, and which is disposed such that the rotational axis thereof follows the aligning direction of the rechargeable batteries. The axial position of the fan is eccentric in the direction of movement of an impeller at an intake chamber side with respect to a center line of the distribution space, the line perpendicular to the aligning direction of the rechargeable batteries. The rechargeable batteries are uniformly cooled within a compact configuration.
