<p><P>PROBLEM TO BE SOLVED: To provide a battery pack which can prevent damages from being given to adjoining batteries 1 and can perform surely heat radiation of the batteries 1 by forming ventilation grooves 5c, 6c communicated by communicating ports 5d, 6d at the battery grooves 5a, 6a of battery spacers 5, 6. <P>SOLUTION: The battery spacers 5, 6 of the following structure are arranged between the battery horizontal groups 2-4. Battery spacers 5, 6 have battery grooves 5a, 6a of circular arc concave shape along the side face of semi-cylindrical shape of each battery 1 of the battery horizontal groups 2-4 formed at both sides in vertical direction. The battery spacers 5, 6 have, further, ventilating grooves 5c, 6c with the deeper groove bottom formed at the central part of the battery grooves 5a, 6a, and have communication ports 5d, 6d opened at the groove walls 5b, 6b between the adjoining battery grooves 5a, 6a. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
