Abstract
A power supply device includes rectangular battery cells, resin separators, end spacers, thick metal end plates, and coupling members. The separatoris inserted between the cellsto insulate adjacent cellsfrom each other, and in thermal contact with the cells. The end spacerscover end battery cellson the opposed end surfaces of a battery block composed of the cellsand the separatorsalternately arranged. The end platescover the surfaces of the end spacers. The coupling memberscouple the end platesto each other. The separatorsform gapsfor flowing air along the surfaces of the cellsin contact with the separators. The end spacershave hollow layerson their surfaces in contact with the cells, and define closed chambers.
