Abstract: A battery pack includes: a battery assembly including a plurality of batteries; a fluid drive member driving a fluid which cools the battery assembly; a housing that houses the battery assembly and the fluid drive member; and a beam provided integrally with a bottom wall of the housing to support the battery assembly from a lower side. A circulation passage provided in the housing includes: a first fluid passage between the battery assembly and a side wall of the housing; a battery passage between the batteries; and a second fluid passage downstream of the battery passage and extending toward the fluid drive member. The second fluid passage is surrounded by at least the beams, the bottom wall, and a lower end of the battery assembly.

Abstract: A battery pack includes multiple sub-modules each of which includes multiple battery cells electrically connected to each other, and an exhaust duct that is provided between and integrated with at least the two battery modules facing each other. The exhaust duct includes therein an exhaust passage that communicates with an outer surface of a safety valve provided in each battery cell in each of the facing battery modules.

Abstract: A battery pack has bus bars, a battery stack which is an assembly of plural battery cells, a bus bar casing which supports a bus bar casing, and a cover member. Electrode terminals of battery cells adjacently arranged in the battery stack are connected together through the bus bars. An upstream side passage and a downstream side passage are formed between the bus bars and the cover member. Upstream side wall surfaces forming an inlet part of the upstream side passage or downstream side wall surfaces forming an outlet part of the downstream side passage is arranged at a location closer to the battery cell side than a location of a surface of the bus bar side.
