Abstract: Electric drive assembly is the core component of battery electric vehicle, and its location is the key to the front compartment layout of the vehicle, which is related to the vehicle performance, front compartment architecture strategy and platform expansion ability. This paper aims to establish a layout architecture for the front compartment of battery electric vehicle, analyzes the spatial characteristics of the front compartment layout of battery electric vehicle, studies the relationship between the key size factors in the layout of the front compartment electric drive assembly around the position of the key components of the front compartment electric drive assembly, and summarizes the layout method of the front compartment electric drive assembly of battery electric vehicle and the layout principles of the surrounding subsystems.

Key words: Battery electric vehicle; Electric drive assembly; Front compartment layout structure; Principle of suspension arrangement
