Abstract

The invention relates to a lithium battery module replacing a lead-acid storage battery for automobiles, comprising an upper cover, a casing, a sealed grid, a lithium battery, an insulating phase-change material, a battery holding component, a heat conduction rib, a battery protection plate and a self-recovery circuit The protector, the upper cover is mechanically connected with the shell to form a sealed cavity, the sealed grid is set in the shell, the sealed grid divides the sealed cavity into the upper half cavity and the lower half cavity, and the insulating phase change material is filled in the lower half cavity In the body, there are multiple lithium batteries, which are connected and fixed through the battery holding component, and are set in the insulating phase change material. The device is set in the upper half cavity, and a circuit is installed in the upper half cavity, one end of the circuit passes through the sealed grid and is connected to the electrode of the lithium battery, and the other end of the circuit is connected to the external pole through the upper cover. Compared with the prior art, the invention has the advantages of long service life, good power characteristics, small volume, high integration and the like.

Description

technical field [0001] The invention relates to a lithium battery module, in particular to a lithium battery module for replacing lead-acid storage batteries used in automobiles. Background technique [0002] After 150 years of development, lead-acid batteries are relatively mature in technology and low in price, and are widely used in the automobile industry. [0003] The main function of the lead-acid battery for vehicles is to provide electric energy to the starter and ignition system (gasoline engine) when the engine is started. When the generator voltage is low or does not generate electricity (engine idling, stop), the function of supplying power to the on-board electrical equipment, assisting the generator in supplying power and storing electric energy. [0004] At present, the service life of lead-acid batteries for vehicles is relatively short, generally about one year, which can easily lead to many discarded lead-acid batteries, and if these discarded lead-acid ba...
