Abstract

An improved electrically powered vehicle and associated method of the type having a mobile electrical storage device for providing electrical power electrically connected to a switching device, for selectively controlling the flow of electric power. The switching device is electrically connected to an electric motor. It selectively allows the flow of electrical power to the motor. The motor is mechanically connected to a belt type continuously variable transmission with the transmission mechanically connected to a drive wheel of the vehicle. It is improved by the motor, being of the direct current type, that is electrically connected to a continuously variable power supply control device responsive to an operator input. Further, the motor is mechanically connected to the continuously variable transmission, with the transmission adapted to respond to the rotational speed of the motor by varying in speed ratio.
