Abstract: A current interruption device includes a deforming plate, a contact plate and a conducting plate which configure a current path. The deforming plate includes one surface on an opposite side from the contact plate facing a first space, a pressure of which is retained to a same pressure as the internal pressure of the casing and the other surface opposed to the contact plate facing a second space, a pressure of which is retained to a same pressure as an external pressure of the casing. When the internal pressure rises above the predetermined level, the second contact portion is separated from the conducting plate by deformation of the deforming plate toward the contacting plate.

Abstract: An electricity storage device includes an electrode assembly, a case, a safety valve, and a cover member. The case accommodates the electrode assembly. The safety valve is arranged in the case and opens to discharge gas out of the case when an inner pressure of the case exceeds a release pressure. The cover member is arranged in the case opposing the safety valve and includes a flow passage for the gas.

Abstract: A battery pack includes a case and a battery module including secondary cells. Each secondary cell includes a primary surface and a secondary surface. The primary surface includes a terminal, and an inter-cell flow passage is formed between adjacent ones of the secondary cells. A primary flow passage is defined between the primary surfaces and a wall surface of the case that faces the primary surfaces. A secondary flow passage is defined between the secondary surfaces and the wall surface of the case that faces the secondary surfaces. One of the primary flow passage and the secondary flow passage functions as a supply passage that supplies a heat medium to the inter-cell flow passage. The other one of the primary flow passage and the secondary flow passage functions as a discharge passage to which the heat medium is discharged from the inter-cell flow passage.
