Abstract

The invention relates to a lithium battery module for replacing a lead-acid storage battery of an automobile. The lithium battery module comprises an upper cover, a shell, a seal grid plate, lithium batteries, insulated phase-change materials, a battery fixedly-held assembly, heat-conducting rib plates, a battery protection plate and a self-restoring circuit protector, wherein the upper cover and the shell are mechanically connected to form a seal cavity, the seal grid plate is arranged in the shell and divides the seal cavity into an upper-half seal cavity and a lower-half seal cavity, the insulated phase-change materials are filled in the lower-half seal cavity, multiple lithium batteries are fixedly connected through the battery fixedly-held assembly and are arranged in the insulated phase-change materials, the heat-conducting rib plates are arranged between each two adjacent lithium batteries, and the battery protection plate and the self-restoring circuit protector are arranged in the upper-half seal cavity; a circuit is mounted in the upper-half seal cavity, one end of the circuit penetrates through the seal grid plate and is connected with the electrodes of the lithium batteries, and the other end of the circuit is connected with an external pole column through the upper cover. Compared with the prior art, the lithium battery module has the advantages of long service life, good power property, 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...
