Electrically propelled vehicles, and a combined energy source and energy reservoir therefor

摘要

A combined energy source and energy reservoir for an electrically- propelled vehicle comprises a flywheel 1 which is also an electrochemical cell or battery of cells. The flywheel-battery serves the electrical traction needs of the vehicle whilst also being adapted to conserve kinetic energy of the vehicle, when the vehicle is braked. The spinning motion of the flywheel-battery also aids the electrochemical action of the battery. The battery is supplied through inlet/outlet 8 by fuel consisting of a slurry of metal particles in an electrolyte which acts in conjunction with air electrodes 5 on the surface of the flywheel-battery to produce the electrochemical effect.
