The invention provides a pure electric vehicle driving system and a performance optimizing method. The pure electric vehicle driving system comprises a first electromotor connected with a first inverter and a transmission module, a second electromotor connected with a second inverter and the transmission module, a first power control module connected with the first inverter and an energy storing module, a second power control module connected with the second inverter and the energy storing module and a torque control module, wherein the torque control module is connected with the first power control module, the second power control module and a sensor, and is used for controlling the torque of the first electromotor and the second electromotor to generate an electromotor torque command, and outputting the electromotor torque command to the first power control module and the second power control module. By adopting the double-electromotor structural arrangement, a power curve can be optimized within a bigger speed range. By adopting the torque control module, the electromotors can work under the optimal torque, the power of a pure electric vehicle is increased, and the torque performance of the pure electric vehicle is effectively improved.
