AI Technical Summary

Problems solved by technology

If the combustible gas is sealed in the casing, the pressure inside the casing will rise, which will cause the casing to deform or cause the combustible gas to explode
If a pressure relief hole is provided in the casing to relieve the pressure, the aforementioned problems can be solved, but when multiple battery cells discharge combustible gas at the same time, it will cause a large amount of combustible gas to escape and cause the danger of ignition, and the water vapor in the environment may also pass through The pressure relief hole penetrates into the casing and damages the battery cell

Embodiment Construction

[0045] refer to Figure 1 to Figure 3 , a preferred embodiment of the present invention provides a lithium battery module, which includes a sealed case 100 , a clamp 200 , at least one soft case capacitor assembly 300 and a control circuit board 400 .

[0046] The sealed casing 100 includes a box body 110 and a top cover 120 . The box body 110 has an opening 111. The upper cover 120 covers the opening 111 to close the box body 110. The inner wall of the sealed casing 100 is covered with a waterproof coating 130. The waterproof coating 130 includes a metal material. In this embodiment, The waterproof coating 130 is a metal foil, and the waterproof coating 130 prevents external moisture from entering the casing 100 . Moreover, the upper cover 120 is provided with a one-way exhaust structure 121 for the gas inside the sealed casing 100 to pass through and be discharged from the sealed casing 100 . In this embodiment, the one-way exhaust structure 121 includes an air channel 122...

Abstract

The invention discloses a lithium battery module. The lithium battery module comprises a sealed housing, a clamp in the housing and at least one soft shell capacitor assembly in the housing. The sealed housing is provided with a one-way exhaust structure. The soft shell capacitor assembly is arranged at the clamp and is extruded and fixed by the clamp. The soft shell capacitor assembly is provided with an exhaust hole. Through the sealed housing and the one-way exhaust structure, the environment can be isolated and pressure release and exhausting can be controlled.

Description

technical field [0001] The invention relates to a lithium battery, in particular to a lithium battery module capable of exhausting and releasing pressure. Background technique [0002] A general lithium battery is mostly composed of a plurality of battery cells connected in series or in parallel. Generally speaking, the battery cells must be arranged in a casing to be protected. When the battery core is not used normally (such as overcharging), the electrodes in the battery core and the electrolyte will react to produce flammable gas. If the combustible gas is enclosed in the casing, the pressure inside the casing will rise, resulting in deformation of the casing or explosion of the combustible gas. If a pressure relief hole is provided in the casing to relieve the pressure, the aforementioned problems can be solved, but when multiple battery cells discharge combustible gas at the same time, it will cause a large amount of combustible gas to escape and cause the danger of i...
