Abstract

The invention provides a lithium battery pack. The lithium battery pack comprises a bolt, a left fixing plate, a right fixing plate and a serial-parallel battery module, wherein two ends of the bolt are respectively connected with a left fixing plate and a right fixing plate, the bolt penetrates the serial-parallel battery module, the left fixing plate and the right fixing plate are respectively connected with the left end and the right end of the serial-parallel battery module, the serial-parallel battery module comprises at least two serial-parallel battery module bodies and switching fixing plates, and every two adjacent serial-parallel battery module bodies are connected through one switching fixing plate and are serially connected through a serial-parallel current-collecting conducting plate to form the serial-parallel battery module. The lithium battery pack has the advantages that the replacement and maintenance of a single battery can be facilitated, the flexibility and feasibility of heat management are enhanced, an insulating fool-proof structural design capable of avoiding assembling safety risks is used, and a modular design capable of avoiding a direct-facing welding process and single-point failure risks is used.

Description

technical field [0001] The invention relates to a soft pack lithium battery module, in particular to a lithium battery pack. Background technique [0002] The grouping method of the traditional soft pack lithium battery pack: the conductive parts are fixed by screws, which may easily lead to the risk of single point failure; the conductive parts are grouped and fixed by welding, the conductive contact area is small and it is difficult to replace and maintain a single section. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a lithium battery pack. [0004] The present invention provides a lithium battery pack, which includes bolts, a group of plastic structural parts and a series-parallel battery module. The group of plastic structural parts includes a left fixing plate and a right fixing plate, wherein the two ends of the bolt are respectively connected with the left fixing plate and the right fixing plate, the bo...
