<P>PROBLEM TO BE SOLVED: To provide a battery pack structure preventing a cooling air flow from blowing at electrodes of batteries while retaining a cooling structure of batteries, and also retaining a mutual electrical insulating structure of neighboring battery vessels and quake resistance. <P>SOLUTION: The battery pack structure is constructed of: a sheet 9 and a sheet 8 wherein a plurality of battery positioning holes 10 are formed at a fixed interval; a plurality of batteries 11 which are so contained into the respective positioning holes 10 of the sheet 9 with their end parts at opposite sides of electrodes fitted in so that a gap 12 is formed between each two neighboring batteries 11; a cap 15 equipped with electrode holes 18A, 18B into which battery electrodes 14A, 14B are inserted, and dividing spaces into an electrode 14A, 14B side and a gap 12 side by covering an electrode side end part of the battery; conductors (bus bars) connecting electrodes among batteries in the electrode side space; and a shielding portion (a case 1, a presser foot board 20, and a top cover 22) shielding the electrode side space from outside. <P>COPYRIGHT: (C)2010,JPO&INPIT |
