Embodiment Construction

[0039] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0040] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

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...
