To save the test energy of the electric drive vehicle, an electric vehicle drive dynamic testing system, with energy recovery is proposed. The electric vehicle DC/AC power drive can be regulated by a speed control mode and a torque control mode in a three-phase electric vehicle induction motor. The three-phase electric vehicle induction motor is directly coupled with a three-phase load induction motor through a coupler. The load of the DC/AC power drive is also regulated by the torque control mode and the speed control mode to drive the three-phase load induction motor. The three-phase load induction motor is operated in the regenerative braking mode, and the regenerative energy of the load induction motor can be transferred to the utility system by a power regenerative DC/AC inverter that feedbacks the energy to the utility system with a unit power factor. Therefore, the proposed electric drive vehicle dynamic testing system not only achieves the dynamic test function, but saves energy.
