The invention relates to the technical field of electric vehicles and provides a power supply system. The power supply system includes a motor controller, an energy battery, a power battery and a vehicle controller. The positive pole of the motor controller is correspondingly connected to the positive pole of the energy battery and the positive pole of the power battery, and the negative pole of the motor controller is correspondingly connected to the negative pole of the energy battery and the negative pole of the power battery. After the situation that the power supply system is switched tothe running state is detected by the vehicle controller, and a motor is enabled and the energy battery is controlled to supply power to the motor; and when accelerated motion of an electric vehicle isdetected, the energy battery and the power battery are controlled separately to supply power to the motor. The power supply system is capable of efficiently distributing and utilizing the electricalenergy of the energy batter
