Abstract
The battery pack holds a first block adjacent to a second block in a case. The first and second blocks are a plurality of circular cylindrical batteries arranged in the same horizontal plane. The first and second blocks are each made up of N batteries lined up side-by-side in parallel fashion to form a lateral battery array, and M perpendicular batteries in close proximity to an electrode end of the lateral battery array and oriented at right angles to the batteries of the lateral battery array. The circular cylindrical batteries of the first and second blocks are arranged with point-by-point symmetry about the center of the rectangular case. Further, the electrode ends of perpendicular batteries protrude beyond a side of the lateral battery array towards the neighboring block to provide center region space between the first and second blocks.
