BATTERY MODULE AND METHOD OF PRODUCING THE SAME

摘要

A first battery row and a second battery row have the same number of cylindrical batteries (2) arranged side by side, and both ends in the battery axis direction of each of the battery rows are held by holding frames (3). Each holding frame (3) is formed in a rectangular solid where an inner frame (4) and two outer frames (7, 8) are separably connected to each other. In each holding frame (3), semicircular arc-shaped cutout-like holding receiving sections (4a, 7b, 8b) of the same number as the number of the batteries in the battery rows are formed in both sides of the inner frame (4) and in those sides of the two outer frames (7, 8) which face the inner frame (4), and half sections of the cylindrical batteries (2) are fitted in the holding receiving sections (4a, 7b, 8b). Two adjacent cylindrical batteries (2) are electrically connected via an inter-battery connection plate (9).
