Abstract

Systems and methods of generating, storing and/or distributing electric power are disclosed. The system may include two or more direct current battery subsystems, a direct current motor/alternating current generator combination, an electric power distribution network, and battery recharging elements. One battery subsystem may power an alternating current generator while the other battery subsystem charges using a portion of the generated power. Excess power may service other electric loads. The roles of the battery subsystems may be switched periodically between charging and powering, repeatedly. A gear box may connect the electric motor and generator to adjust the relative rotational speeds of each for optimal performance of the system.
