The layout of the high-voltage wiring harness of electric vehicles needs to be based on the principle of proximity, using as few high-voltage cables as possible to complete the layout. This principle not only meets the requirements of general layout and high-voltage electrical design, but also meets the purpose of cost reduction, efficiency increase and weight reduction of the whole vehicle .
The first principle of safe arrangement of high-voltage wire harnesses is to prevent drivers, passengers or maintenance personnel from directly touching high-voltage wire harnesses.
Based on this principle, it is forbidden to arrange high-voltage wiring harnesses in the passenger compartment, and avoid arranging high-voltage wiring harnesses in the luggage compartment.
If due to design requirements, it is really necessary to arrange high-voltage wire harnesses in the above-mentioned areas, the high-voltage wire harnesses should be arranged under the chassis of the vehicle through holes in the body sheet metal in consideration of collision safety, high-voltage safety, and parts use safety. It is covered with a cover to avoid accidental touch by personnel.
