Abstract

The invention discloses a balanced explosion-proof valve for a ternary lithium power battery pack. The balance explosion-proof valve comprises an end cover arranged on a valve body, an ejector rod assembly, a reset elastic piece and a protective cover, the end cover is arranged on a gas circulation opening in the outer side of the valve body, the ejector rod assembly is connected with the end cover, the internal blasting force of the valve body is the driving force of the ejector rod assembly, and the reset elastic piece is arranged between the ejector rod assembly and the shell and used for resetting the ejector rod assembly. The protective cover is arranged on a gas spraying path on the inner side of the valve body and used for filtering a circulating gas. By means of the mode, the valve port can be opened through the ejector rod assembly, when the situation that explosion is out of control occurs in the battery pack, the valve port can be opened in time, internal pressure is discharged, the internal pressure is kept balanced, the anti-explosion effect is achieved, and the safety coefficient is increased.

Description

technical field [0001] The invention relates to a balanced explosion-proof valve for a ternary lithium power battery pack. Background technique [0002] When the battery is impacted or short-circuited, a large amount of gas will be generated inside the battery, so the battery pack is equipped with an explosion-proof valve, but most of the explosion-proof valves used in the current battery pack do not have the function of controlling the pressure of air in and out, and the safety performance cannot be guaranteed. Assured, the hazard level remains high. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a balance explosion-proof valve for a ternary lithium power battery pack, which can balance the internal and external pressure in time when the inside of the battery pack is out of control, and play an explosion-proof role. [0004] In order to solve the above-mentioned technical problems, a technical solution adopte...
