The invention provides an extended-range electric vehicle power supply system. The system comprises a range extender, a high-power energy type power battery, a high-magnification type power battery, avehicle control unit, a power distribution unit, a driving motor controller, a driving motor and an energy recovery system. The range extender can charge a high-power energy type power battery through a vehicle-mounted charger; the driving motor controller can take electricity from the power distribution unit to supply power to the driving motor or charge the high-magnification power battery withthe electricity generated by the driving motor through the energy recovery system under a torque or power instruction of the vehicle control unit; and the range extender, the high-power energy type power battery and the high-magnification type power battery can be connected with the power distribution unit through high-voltage cables. The invention further provides a configuration method of the extended-range electric vehicle power supply system. On and off of the high-power energy type power battery, the high-magnification type power battery, the range extender and the driving motor controller can be determined under the torque or power instruction of the vehicle control unit.
