Abstract
A battery pack includes plural battery cells (), and insulating separators () disposed between adjacent battery cells (), where the plurality of battery cells are disposed in a stacked configuration with a prescribed gap between the adjacent battery cells. A separator () has plural gas channels that enable the flow of cooling gas. The gas channels have cooling gas entranceways and exit ways, which open at the sides of the battery block formed by the stacked battery cells. The separator 10 has cut sections formed to position the entranceways and exit ways of the gas channels inward from the sides of the battery block. This allows cooling gas near entranceways and exit ways to be smoothly introduced to, and exhausted from the gas channels, and reduces cooling gas pressure losses in those regions.
