Abstract: An energy storage apparatus includes one or more energy storage devices and an outer housing that houses the one or more energy storage devices. The outer housing includes an opening that allows communication between an interior and an exterior of the outer housing. The opening is sealed by a first pressure adjuster and a second pressure adjuster arranged complementary to each other. The first pressure adjuster allows passage of gas and prohibits passage of liquid. The second pressure adjuster prohibits passage of the gas and the liquid, and releases an internal pressure in the interior of the outer housing when the internal pressure exceeds a predetermined pressure.

Abstract: An electric storage device includes an electric storage element including an external terminal, and a bus bar connected to the external terminal. The bus bar includes a thin-walled portion and a thick-walled portion, the thin-walled portion being located around outer edges of the bus bar. The thin-walled portion and the external terminal are directly welded together. A thickness of the thin-walled portion is less than a thickness of a remaining portion of the bus bar including the thick-walled portion.

Abstract: An energy storage apparatus includes one or more energy storage devices, and an outer housing that houses the one or more energy storage devices. The outer housing includes an outer housing main body, a cover that closes an opening of the outer housing main body, an outer terminal disposed on the cover, and a communication part defining a passageway allowing a communication between an interior and an exterior of the outer housing. The communication part includes a functional membrane. A ventilation hose for passage of a gas, which has passed the functional membrane, is connected to an end of the communication part.
