APPARATUS FOR STORING AND RELEASING ELECTRICAL ENERGY USING A FLYWHEEL AND A PLURALITY OF ELECTROCHEMICAL ACCUMULATORS

摘要

An apparatus for transferring energy from cell to cell of a battery, wherein each cell is connected to its individual electrical motor/alternator through an electronic module, and wherein each motor/alternator is mechanically connected to a common flywheel. The electrical motor/alternator preferably is an electrical motor that provides rotational work and generates power when being driven by an external source of rotational kinetic energy or by an external source of rotational power. The common flywheel stores rotational kinetic energy. Cells of the battery provide various torque on the flywheel or on the shaft driving the flywheel. Cells with higher than average output current will provide higher than average torque, thus providing higher than average kinetic energy input to the flywheel, while cells with lower than average output current will provide lower than average torque, or will provide negative torque, the motor/alternator acting then as an alternator recharging the cell.
