The invention provides an acceleration anti-slip control system and a method of a pure electric vehicle. The acceleration anti-slip control system comprises a gear selector, a brake pedal, an accelerator pedal, a whole vehicle controller, an anti-lock brake system and a motor controller; the gear selector, the brake pedal and the accelerator pedal are respectively connected with the whole vehicle controller and used for transmitting present gear signals, on/off signals of the brake pedal and openness signals of the accelerator pedal to the whole vehicle controller; and the whole vehicle controller is respectively connected with the anti-lock brake system and the motor controller by CAN buses. In the acceleration anti-slip control method, a target is controlled by using optimal slippage rate and the slippage rates of the wheels are controlled to be near the optimal slippage rate by regulating control parameters, so that the vehicle can obtain excellent acceleration anti-slip control effect when traveling under severe road conditions; and moreover, the wrong judgment of the slipping of tires during steering is avoided effectively by identifying steering conditions.
