The invention relates to the field of electric vehicle control, provides a power domain motor controller for an electric vehicle, and aims to solve the problems of large number of controllers, high cost, large number of wire harnesses and the like caused by using a single chip for driving control. The controller comprises a control panel, a low-voltage interface unit and a driving control unit, and the control panel receives vehicle control unit instruction information from the electric vehicle and information from the driving control unit in a CAN communication mode and sends instruction signals to the driving control unit. The driving control unit performs signal interaction with the control panel in a bus communication mode and performs driving control on driving equipment electrically connected with the driving control unit; the low-voltage interface unit connects the driving control unit with the control panel through a wire harness and is used for data interaction between the driving control unit and the control panel. A single chip is used for controlling a plurality of motors, the system complexity is reduced, the number of wire harnesses is reduced, and the system reliability is improved.
