An electric vehicle (1) comprising a charging circuit (11), a battery (12) and a driving electric motor (13) connected to each other, and an air compressor (14), a gas storage tank (15), a turbine (16) and a generator (17) connected to each other. Air is compressed and stored in the air storage tank when the air compressor starts up. The air storage tank is provided with a corresponding switch valve, and under the control of the switch valve the stored air is fed to the turbine. The turbine converts the air energy of the introduced air into kinetic energy, thereby driving the generator to generate electrical power. The generator is connected with the driving electric motor or the battery, for supplying power to the driving electric motor or for charging the battery during power generation. By means of providing an air compressor, an air storage tank, a turbine and a generator, and using air energy to generate power and the battery to supply power in parallel, the continuous mileage of the electric vehicle is increased. In addition, the service life of the battery is prolonged, because the battery is used in a low depth of charge/low depth of discharge manner. |
