Double-energy double-voltage power supply system

The invention relates to a double-energy double-voltage power supply system applicable to gasoline engine driven automobiles. The system can meet the power supply requirement of adding a hybrid drive function to the gasoline engine driven automobiles on the basis that the original functions of the original automobiles are unaffected, solar energy can be fully utilized to participate in supplying power to direct-current motors so as to drive the automobiles, and accordingly the automobiles are more energy saving and environment friendly.
