Abstract: A smart charge and power supply device for mobile vehicles comprises a transmission, a power generator having a free wheel and connected to the transmission, a first battery, a second battery, a first switching mechanism connected between the transmission and the first and the second batteries, and a second switching mechanism connected between the power generator and the first and the second batteries. The transmission is provided for driving a transmission mechanism of an electric mobile vehicle. The free wheel is driven by the transmission and has smooth rotational movements to improve the efficiency of the power generator in generating power to charge the batteries. The first and the second switching mechanisms are provided for switching one of the first and the second batteries supply power and charging the other for driving the mobile vehicle and having the power generator to charge a weak battery.
