COMBINATION BATTERY

摘要

A combination battery is constructed by having battery modules (2) that are constituted of single batteries each formed by receiving a power generation element in a square case, with the single batteries (5) connected to each other in series and gaps (8) formed between adjacent single batteries (5, 5), and a restraining jig having connection members (4) arranged through both ends of parallelly arranged battery modules (2) and through gaps (8) between any adjacent single batteries (5, 5). The structure above enables the restraining to be reliably made with the use of a restraining jig having even relatively low rigidity, and as a result a combination battery with reduced weight and cost is provided.
