Abstract
A flywheel with electric batteries mounted thereon is provided for an electrical vehicle. The flywheel incorporates the weight of the batteries to store kinetic energy. The flywheel is suspended by magnetic force and is rotated about a central flywheel shaft. The flywheel shaft is fitted with an electric drive motor, a hydraulic pump and a generator. The electric vehicle utilizes the energy stored in the spinning flywheel to supply peak electrical demand during the acceleration of the vehicle. When the vehicle stops the flywheel energy recharges the electrical batteries. The flywheel is driven by the electric drive motor. The hydraulic pump is used to drive a hydraulic motor which in turn drives the vehicle wheels. When the hydraulic motor brakes the wheels, kinetic energy is stored into the flywheel. The generator supplies supplemental vehicle power.
