Problems solved by technology

[0004] In an electric storage device using such an exhaust valve, there is no fear that foreign matter such as water droplets will enter the inside of the case through the exhaust valve during normal use, but the structure of the exhaust valve is complicated, so it is easy to become a problem with high product costs. reason
In addition, in the case of using this power storage device, the entry of foreign matter from the outside cannot be prevented after the exhaust valve has been operated once.

Abstract

The power storage device includes: a secondary battery (11); a case (10) formed in a substantially rectangular parallelepiped shape for accommodating the secondary battery (11) in a sealed state inside the case (10); and An exhaust valve (31), which releases the pressure inside the casing (10) to the outside when the pressure inside the casing (10) rises above a set pressure. The exhaust valve (31) is composed of a valve element capable of opening and closing the exhaust passage (26) according to the pressure inside the housing (10). A recess (30) open on the upper side and one side is provided on the upper wall (10a) of the casing (10). The concave portion (30) is covered above by a cover member (40). An exhaust valve (31) is disposed inside the recess (30). A ventilation gap (45) is provided between the bottom surface (30a-1) of the open portion (30a) on one side of the recess (30) and the cover member (40).

Description

technical field [0001] The present invention relates to an electrical storage device. Background technique [0002] As an electrical storage device mounted on a vehicle or the like, there is known an electrical storage device in which a secondary battery such as a lithium-ion battery is housed in a sealed state inside a case and is provided with a device in which the pressure inside the case is increased to a set value. An exhaust valve that releases the internal pressure to the outside when the pressure is higher (for example, refer to Patent Document 1). [0003] The part of the exhaust valve provided in this kind of power storage device that communicates with the inside of the casing is closed by a deformable sealing member. Components break due to contact. The exhaust valve discharges the gas inside the casing to the outside by breaking the sealing member. [0004] In an electric storage device using such an exhaust valve, there is no fear that foreign matter such as ...
