The invention discloses a motor control circuit for an electric vehicle and a control method thereof, and relates to the technical field of electric vehicle motor control. The motor control circuit comprises a motor, a VCU module, an IGBT module and a charging interface, wherein the IGBT module is electrically connected with the charging interface sequentially through the motor, the VCU module andthe charging interface. The IGBT module and the motor unit of the electric vehicle are fully utilized, so that the integration level of an electrical system of the electric vehicle is improved; the electric vehicle using the circuit does not need an external direct-current charging pile and can be directly charged through the alternating-current quick-charging pile, so that the energy damage of the direct-current quick-charging pile in the ACDC conversion process and the cost of a power device are reduced; meanwhile, the V2G technology is achieved, the electric vehicle can be charged and discharged in an off-peak mode for the power grid, when charging is not needed, the electric quantity can be sold to the power grid all the time through the vehicle electricity utilization wave crest, economic benefits are obtained, when the electricity utilization wave trough is low in price, the whole vehicle is charged, and the electricity utilization cost is saved.
