Electric automobile chassis calculus battery pack

Abstract

The invention relates to an electric automobile chassis calculus battery pack. The electric automobile chassis calculus battery pack comprises a chassis; the upper plane of the chassis is provided with battery installing grooves; the battery installing grooves are provided with calculus battery monomers; the calculus battery monomers comprise a plurality of overlapped battery monomers Ei; the calculus battery monomers are arranged on the transverse plane and the longitudinal plane of the chassis in a matrix block manner according to the shape and the size of the chassis; an A battery pack matrix is formed on the transverse plane X-Y, and a B battery pack matrix is formed on the longitudinal plane X-Z. According to the matrix arrangement of the calculus battery pack, breaking up the whole of large heavy battery monomers into parts is realized, the electric automobile chassis calculus battery pack is embedded into an electric automobile chassis, space occupied by electric automobile batteries is reduced, uniform automotive body mass distribution is realized, it is convenient for battery chassis production modularization, and convenient for automotive body modularization final assembly, and at the same time, battery safety in electric automobile body collision is improved.

Description

technical field [0001] The invention relates to an assembly arrangement structure of a power battery pack of an electric vehicle, in particular to a calculus battery pack embedded in a plastic chassis formed by a rotational molding process. technical background [0002] At present, due to the change of urban environment and the shortage of energy resources, electric vehicles with environmental protection and energy saving have been paid attention to by transportation, energy and other departments, and great progress has been made in recent years, especially the various performances of electric vehicle batteries. Greater improvement. These are expected to promote the large-scale industrialization of electric vehicles. [0003] Electric vehicle battery pack is not only the core of electric vehicles, but also a comprehensive embodiment of automotive engineering and power engineering technology. The design of electric vehicle battery packs not only needs to consider the matchi...

AI Technical Summary

Problems solved by technology

[0004] In addition, after the battery pack has been fully assembled, when some of the battery cells have problems, the entire battery needs to be disassembled for maintenance, which not only increases the maintenance cost, but also increases the difficulty of maintenance.

In order to solve the problems of inconvenient disassembly and assembly of the battery pack and insufficient flexibility in use, it is proposed in the patent CN2010192446007.3 to realize the free assembly of the battery cells through the battery installation components of matching dovetail grooves and convex strips
