Abstract: High voltage electrical architecture design of pure electric vehicles has an important impact on the cost, safety and reliability of electric vehicles. The performance parameters of highvoltage electrical components are determined based on the performance requirements of the vehicle. In order to meet the functional requirements and safety requirements of the vehicle, the independent high-voltage electrical architecture and the integrated design high-voltage electrical architecture are compared and analyzed. It is concluded that the integrated design high-voltage electrical architecture can reduce the use of high-voltage connectors, wires, relays, fuses and other electrical components, thus reducing the cost. It is beneficial to the optimization of vehicle layout space and lightweight design of high-voltage electrical components.
