This shift has major implications for OEMs in terms of architectural design, as a pure electric vehicle must provide power not only to drive the wheels of the vehicle, but also to operate other equipment in the vehicle; while in gas-powered or hybrid vehicles In , the engine not only provides power to drive the car, but also provides electricity to other equipment in the car. Without the engine, pure electric vehicles must adopt a completely new electrical architecture design.
Moving from an internal combustion engine or a hybrid vehicle to a pure electric vehicle requires thicker and heavier wires and connectors to accommodate more power. However, the space of the vehicle chassis is limited, and the high-power distribution system has a larger size and mass, which brings greater challenges to the vehicle packaging design.
