BATTERY PACK

摘要

A battery pack includes a plurality of battery modules; at least one space that is formed between the battery modules that are adjacent to each other, and that serves as a flow path for a heat carrier; and a plurality of protrusions that protrude toward an inside of the space, and that are arranged on surfaces of opposing surfaces that oppose each other and that define the space. The plurality of protrusions that are arranged on one surface of the opposing surfaces and the plurality of protrusions that are arranged on the other surface of the opposing surfaces are arranged in positions that oppose each other across the space.
