  • Switching time control multiplexer system
    Patent number: 8183818
    Abstract: A system for energizing an energy storage device includes an electric power source, an energy system in communication with the electric power source, and a switching time control multiplexer. The energy storage system includes at least two parallel energy storage devices. The switching time control multiplexer is configured to supply total charging current from the electric power source to the energy storage system such that each storage device is charged in an alternating manner with the total charging current being less than a total charging current required for parallel charging.
