<p><P>PROBLEM TO BE SOLVED: To provide a battery pack in which heat generated inside a case can be discharged outside efficiently, and reliability is promoted. <P>SOLUTION: The battery pack has a battery block which is provided with a plurality of batteries, lead plates that support batteries in an almost parallel state mutually by fixing end faces of the plurality of batteries, and spacers having insulating property to partition between adjoining batteries from each other, has a plate board that is arranged on one face of the battery block and is mounted with electronic circuits to be wired with the batteries, and has a housing case to house the battery block and the plate board. This battery pack is constituted so that a part of the lead plate is protruded to form a lead protrusion part in order that the heat is discharged with this lead protrusion. By this, the lead protrusion for discharging the heat generated by the batteries can be used in common as a terminal for detecting the intermediate potential of the battery group built in the battery pack. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
