Abstract
A battery system has a battery block with a plurality of battery cells that are rectangular batteries stacked with intervening insulating separators, and that battery block is held by fastening components. The fastening components are provided with a pair of endplates disposed at the ends of the stacked battery cells, and metal bands on both sides of the battery block connected at both ends to the endplates. An insulating separator has an insulating plate section, which intervenes between adjacent battery cells, and insulating walls, which cover both battery cell side-walls, formed from plastic as a single-piece. In this battery system, insulating plate sections are sandwiched between battery cells, and the insulating walls are disposed between battery cell outer side-walls and metal bands to insulate the battery cells from the metal bands.
