<p><P>PROBLEM TO BE SOLVED: To reduce a difference in temperature among batteries in a battery block contained in a battery case, while attaining low cost mass production using a very simple structure, and to reduce a difference in temperature among batteries, while effectively eliminating heat confinement among a plurality of battery blocks by a natural convection and disposing many batteries at correct positions. <P>SOLUTION: In a battery pack, the battery block 10 configured by disposing the plurality of chargeable batteries 1 at fixed positions by a battery holder 2 is contained in a battery case 3. In the battery pack, the plurality of battery blocks 10 are contained in the battery case 3 at predetermined intervals; a hollow partition wall 32 the inside of which is made hollow to form a hollow part 33 which is opened to a surface of the battery case 3 is disposed between the adjacent battery blocks 10; and the battery block 10 is disposed to be thermally coupled with the hollow partition wall 32. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
