Because CAN bus has high efficiency in data exchange and strong ability in anti noise, it became the preferred internal communication network of electric vehicle. The three-phase inverter of electric vehicle introduced in this paper is vehicle auxiliary inverter of electric inverter and it is known as the auxiliary electrical power source”, which provides load to AC motor among various departments of the electric vehicle, such as the compressor of the electric vehicle’s air conditioning system, power steering pump, brake air pump of electric vehicle and water pump in cooling water cycle. In the design of electric vehicle’s auxiliary power, it requires: (1) keep stable operation of the inverter auxiliary engine in the process of travailing and corresponding working condition can be made according to the requirements of host computer ; (2) when the load power failure of electric vehicle such as engine short-circuit happens, the output needs to be disconnected to secure safe shutdown. Fault happened needs to the various panel points and the host computer through the CAN bus control and every fault in the bus needs to be operated, such as early warning signs in display system of electric vehicle to remind the driver to slow down.
