The invention provides a novel electric vehicle starting method and system. The method comprises the following steps that an electric vehicle rotating handle rotates to send out an electric signal; performing linear integration on the electric signal sent by the rotating handle to obtain a starting signal; and the driving controller receives a starting signal obtained in the linear integration process, outputs a driving signal of which the frequency is linearly increased based on the starting signal, and drives the motor to linearly increase the rotating speed until the starting is completed. According to the invention, the constant acceleration starting of the motor is realized, so that the starting current is reduced, the waste of the current is avoided, the energy efficiency during the starting of the motor is improved, and the endurance mileage of the electric vehicle is improved.
