Layout design method for chassis charging electromobile power battery box assembly

Abstract

The invention relates to a layout design method for a chassis charging electromobile power battery box assembly, and the method comprises the following steps: confirming chassis layout plan of a chassis charging electromobile; confirming structure of a power battery box according to the chassis layout plan of the chassis charging electromobile and integrated vehicle performance; combining handling stability and chassis space for confirming centroid arrangement position of the power battery box assembly; combining riding comfort and the centroid arrangement position of the power battery box assembly for confirming arrangement position of connecting point between the power battery box and the chassis. The layout design method for chassis charging electromobile power battery box assembly adopts multi-body dynamics method, test optimization strategy and finite element and the like for comprehensively confirming the arrangement position of the power battery box assembly and the arrangement position of the connecting point between the power battery box and the chassis, handling stability and riding comfort are comprehensively considered during the design process, and vehicle performance of chassis charging electromobile improved based on conventional fuel cars is greatly improved.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a method for designing the arrangement and design of a power battery box assembly of a chassis-replaced electric vehicle. Background technique [0002] Due to its low emission, low noise, high energy utilization rate and wide range of energy sources, electric vehicles are becoming a new direction of automobile development. Limited by battery technology, the energy ratio of the battery is very low compared with traditional fuel, so the mass of the power battery box assembly accounts for a large proportion of the vehicle's mass, resulting in the vehicle's handling stability and ride comfort in electric vehicles developed based on traditional vehicles poor condition. [0003] The so-called chassis swapping electric vehicle refers to an electric vehicle that can quickly replace the power battery box through automatic equipment in order to solve the problem of short mileage of electr...

AI Technical Summary

Problems solved by technology

[0004] For the traditional electric vehicle chassis layout scheme, it is only based on the mileage of the vehicle and the chassis space. After determining the structure of the battery box, it is arranged under the chassis of the vehicle. It does not consider the impact of the layout of the power battery box assembly on the handling stability and ride comfort of the vehicle. Influenced by the impact of the traditional fuel vehicle, the performance of the whole vehicle is not good.
