PURPOSE: A power supply unit of vehicles is provided to simply connect electrodes in multi-parallel multi-series blocks and to improve battery output. CONSTITUTION: A power supply unit of vehicles includes: a battery having positive/negative electrode portions; parallel blocks which are parallelly connected by laminating the battery; multi-parallel multi-series blocks which serially connect the parallel blocks; and bus bars(30,40,42) which have a plurality of insert holes(36a-36f) and electrically connect the batteries by inserting the positive/negative electrode portions into the insert holes. The battery of the parallel block is laminated so that the positive electrode portion is arranged to one side of the parallel block and the positive electrode portion is arranged to the other side of the negative electrode portion. |
