Abstract

The invention discloses a liquid-cooled power battery pack for providing power for electric vehicles. The main structure includes a liquid-cooled plate, a box body, a BMS device installed in the middle of the liquid-cooled plate, a battery module installed at one end of the liquid-cooled plate, The electrical component group, several beams, and liquid-cooled tubes installed at the other end of the liquid-cooled plate. The liquid-cooled battery pack has the characteristics of high heat dissipation efficiency, good reliability and excellent safety performance. The manufacturing cost is relatively low, and the functional requirements can be realized with high standards at a relatively low cost, and mass production can be easily realized.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a liquid-cooled power battery pack for electric vehicles. Background technique [0002] At present, there are many kinds of battery packs on the market, but most of them have problems of one kind or another. If the structural design is unreasonable, the battery cells cannot be placed properly; the heat dissipation effect is poor, resulting in abnormal temperature rise of the battery pack as a whole; The structure of the entire electric vehicle liquid-cooled power battery pack is improved. Contents of the invention [0003] In order to solve the above existing problems, the present invention provides a liquid-cooled power battery pack for electric vehicles. The power battery pack adopts a modular design and has a simple structure. The cooling method is liquid cooling, and the heat dissipation effect is good. Within a reasonable range, it adopts various common parts...
