Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of motor control for electric vehicles, and in particular relates to a motor control circuit for electric vehicles and a control method thereof. Background technique [0002] At the same time, in recent years, with the vigorous development of the electric vehicle industry, on-board electronic equipment has shown a trend of miniaturization, integration, and high power density. Considering cost savings, power devices can allow multiple power module units to be reused to save Space size and cost, especially with the motor controller MCU (Motor Control Unit) and on-board OBC (On Board Charge) charger as the core components of the electric energy conversion of the entire electric vehicle, there is an urgent need for miniaturization and high integration. [0003] The existing product MCU and on-board OBC are basically independent products. As the key module and core cost device in the car, the IGBT in the MUC is g...
