Outline
In order to clarify the key technology of pure electric vehicle body design, the difficulties of pure electric vehicle body design and corresponding solutions are discussed. Firstly, from the perspective of the important parts carried by electric vehicles and traditional fuel vehicles, the differences between electric vehicles and fuel vehicles are revealed. Then, the difficulties in the body design of pure electric vehicles are described, and the solutions of the body structure design of electric vehicles are given for each difficulty. It includes the complete and continuous design of the body bottom beam system structure, the crashworthiness design of the side column collision, the installation point design of the front and rear suspension of the body, the waterproof design of the body, the aluminum alloy body design, the locking technology of the whole vehicle electric change and the powertrain suspension technology. To sum up, the analysis shows that mastering these key technologies will make it easier to achieve the expected goal in the body structure design of pure electric vehicles.
