Abstract
An electric vehicle comprises an air tank (11, 21, 31) and an air turbine (12, 22, 32) connected to the air tank and an electrical power generator (13, 23, 33) respectively. The air tank is provided with an air charging interface and a switching valve, external compressed air is stored into the air tank through the air charging interface, and the stored compressed air is output to the air turbine under the control of the switching valve. The air turbine converts air energy of the input compressed air into kinetic energy for driving the electrical power generator to generator power. The electrical power generator is connected to the driving motor (14, 24, 34) and is used for supplying power to the driving motor when generating power. The electric vehicle has increased travel distance per charge and elongated service life of the storage battery, and is environmental friendly and energy saving.
