<p><P>PROBLEM TO BE SOLVED: To enable radiation of the heat of batteries, by improving heat conduction from the batteries to the side wall, and to improve impact resistance strength by closing the gap between the end face of the batteries and the sidewall. <P>SOLUTION: The battery pack has a plurality of batteries 2 arranged in parallel in the body case 1A having side walls 11 along the periphery of a bottom plate 10, and, by housing the end face of the batteries 2 facing the sidewall 11, closes the opening part of the body case 1A by a lid case 1B. The battery pack has a spacer 3 made of plastic between the batteries 2. This spacer 3 has a clearance plate 6, arranged between the end face of the batteries 2 and the sidewall 11 molded integrally with a spacer body 3A arranged between the batteries 2. In the battery pack, the spacer body 3A is arranged between the batteries 2, and the clearance plate 6 molded integrally with the spacer body 3A is arranged between the end face of the batteries 2 and the sidewall 11 of the body case 1A, thereby, the heat of the batteries 2 are conducted to the sidewall 11 through the clearance plate 6. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
