<P>PROBLEM TO BE SOLVED: To provide a storage battery module including a cooling mechanism capable of surely radiating heat of storage battery cells constituting the storage battery module. <P>SOLUTION: The present invention relates to a storage battery module having a structure where a plurality of storage battery cells, e.g., cylindrical batteries 1 disposed over a plurality of lines and a plurality of stages are held by an insulated battery holding plate 9 so as to be integrally accommodated in a battery box. In the battery holding plate 9, a hollow structure is formed and in the hollow structure, a heat conduction member 7a for heat exhaustion is buried for exhausting generated heat of each storage battery cell, e.g., each cylindrical battery 1, outside of the battery box, and a part of the heat conduction member 7a for heat exhaustion or a heat sink 7b with a fin concatenated to the heat conduction member 7a for heat exhaustion is disposed at a position directly exposed under cooling winds from a cooling fan 13 with a box attached to the battery box. The hollow structure is formed at a position inside the battery holding plate 9 opposed to an intermediate position of each stage of each of the cylindrical batteries 1 disposed over a plurality of lines and a plurality of stages, the position being in parallel with an arrangement of electrode parts of the cylindrical batteries 1 in the respective lines. <P>COPYRIGHT: (C)2012,JPO&INPIT |
