A lithium battery module

Abstract

The invention discloses a lithium battery module, comprising: a module shell, a positive electrode column, a negative electrode column, a monomer shell, a battery monomer, a bus bar assembly, an automatic fire extinguishing device and an automatic cooling device, wherein, the root of the positive electrode column or the negative electrode column is provided with a flexible fuse electrode; The single housing is provided with a plurality of, and laminated on the inside of the module housing; The monomer shell is composed of non-conductive insulating material. The battery cell is fixedly installed inside the battery cell; The automatic fire extinguishing device is arranged inside the single shell; The automatic cooling device is arranged at the bottom end of the module housing. The lithium battery module provided by the invention is provided with a power-off protection device, which can automatically cut off the power supply connection when a short circuit occurs inside or outside the battery; An automatic fire extinguishing device is arranged, and the fire extinguishing device is automatically turned on when a fire occurs, so that the disaster situation can be effectively controlled;It is equipped with automatic cooling device to control the temperature of the battery module in the proper range, and the safety factor is very high.

Description

technical field [0001] The invention relates to the technical field of batteries, and more particularly to a lithium battery module. Background technique [0002] The world's energy and environmental protection situation is becoming more and more tense, and batteries are increasingly favored by people as a power source. Lithium batteries have gradually become the first choice in the energy field due to their high energy density, small size, light weight, environmental protection, no pollution, and no memory effect. [0003] With the large-scale use of lithium batteries, the market's demand for safety and reliability of lithium batteries continues to increase. However, in high-power applications such as post and telecommunications, energy storage, and electric vehicles, lithium batteries require a series-parallel combination of multiple batteries to meet the needs of voltage and power. Because lithium batteries are prone to heat, fire and smoke, and when one of the lithium ...

AI Technical Summary

Problems solved by technology

Because lithium batteries are prone to heat, fire and smoke, and when one of the lithium batteries heats up, it may cause the overall abnormality of the lithium battery pack, which will bring various unsafe factors to the power supply device; in addition, due to differences in production processes, Affected by external conditions such as battery line aging and load performance changes, the battery pack may be short-circuited. After the battery is short-circuited, it is easy to cause damage such as load burnout and battery emptying, causing great damage; cause fire, even casualties
