<p><P>PROBLEM TO BE SOLVED: To prevent breakage of a connection portion of a rack side and a battery module due to vibration. <P>SOLUTION: A bus bar 5 is provided on a back board 4 of a rack 2, and projection pieces 6a, 6b projecting inside a module housing block 3 are provided at an end of the bus bar 5. Fork-type connectors 9a, 9b for a positive electrode and a negative electrode having a pair of opposed fork pieces 10 are provided on a tip face 8 in an insertion direction when a battery module 7 is mounted to the module housing block 3. The battery module 7 is inserted and housed in the module housing block 3, so that the projection pieces 6a, 6b of the corresponding bus bar 5 are held and connected by the respective fork-type connectors 9a, 9b. Even when the battery module 7 is displaced in the module housing block 3 by vibration applied to a power storage system, a connection condition is maintained by displacement and angle change of the respective fork-type connectors 9a, 9b from the projection pieces 6a, 6b of the bus bar 5. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
