An auxiliary charging system for electric vehicles comprises a hopper (4) located in a front part of a vehicle and for concentrating the air; a fan (5) for producing rotary power according to the wind pressure induced through the hopper (4); a generator (8) for generating the electric power according to the rotary power; a fan rotary power regulator (6) located between the fan (5) and a shaft of the generator (8) to transfer the rotary power to the generator (8); a sensor (7) for detecting rotation number of the fan (5) as electric signal; a plurality of solar cells (9) mounted on an upper part of a roof (14) of the vehicle to convert the solar energy into the electric energy; a charge circuitry (10) for charging a lead storage battery (1) by using the electric energy of the generator (8) and the solar cells (9); an overcharge inspecting means (11) for inspecting the lead storage battery (1) for overcharge; and a controller (12) for outputting operation signal or blocking signal to a regulating gear (61) of the fan rotary power regulator (6) according to the rotation number of the fan (5) and the overcharging state of the lead storage battery (1), so that since the lead storage battery is continuously charged by the strong wind or the sunlight during drive or stop of the electric vehicle, mileage of the vehicle can be steeply extended and the charging expenses of the lead storage battery can be considerably reduced. |
