Levistor’s solution is aimed at rural locations when it would be too costly to upgrade the electrical supply. It stores up energy from the grid when there are no vehicles charging. The stored energy can then be supplied at high speed (up to 350kW) to electric vehicles when they arrive and demand a fast charge.
Their kinetic energy system or “mechanical batteries” stores energy in a rotating shaft – essentially a flywheel. Electrical energy is added through an electric motor (speeding up the shaft) and taken out through a generator (slowing down the shaft).
Levistor has received funding from the UK Government’s ‘Transitioning towards Zero Emission Vehicles’ programme.
