Abstract

The application discloses an explosion-proof valve for electric cores, electric cores and battery modules. The explosion-proof valve includes: a base, the base is ring-shaped and suitable for being fixed on the cover plate of the electric core; The valve plate is fixedly connected to the inner periphery of the base and protrudes outward; wherein, the thickness of the base is greater than that of the valve plate. The explosion-proof valve according to the present invention has a valve plate and a base, the thickness of the valve plate is smaller than the thickness of the base, the valve plate has a first section line extending in the length direction, and the thickness direction of the valve plate is at the first section line. The upper section is an arc section, the radius of the arc section is R1, and the R1 satisfies: 50mm≤R1≤200mm, the valve plate can be broken in time after the pressure of the battery cell reaches the preset value, and the reaction speed is fast , good safety performance, the cross-section of the valve plate in the thickness direction is arc-shaped, which improves the pressure resistance of the valve plate and reduces the manufacturing cost of the valve plate.

Description

technical field [0001] The present application relates to the field of batteries, in particular to an explosion-proof valve for batteries, batteries and battery modules. Background technique [0002] In the related technology, after the internal air pressure of the battery cell reaches the preset value, the explosion-proof valve responds slowly, and cannot obtain a through hole connected to the inside of the battery cell in a timely and stable manner, resulting in the inability to reduce the pressure in the battery cell in time, and the battery The safety performance of the core is poor. Contents of the invention [0003] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present application is to propose an explosion-proof valve for electric cores. The explosion-proof valve has a valve plate and a base, and the thickness of the valve plate is smaller than the thickness of the base, so that th...
