  • Publication number: 20040232879
    Abstract: A process for transferring electrical energy from a first electrical energy storage device to a second, rechargeable electrical storage device. In this process, the voltage in the energy storage devices are sensed and the difference in such voltages is determined. The rate of current flow from the first to the second energy storage device (and vice versa) is then repeatedly adjusted. A controller, which is preferably powered by the first and second storage devices, monitors and adjusts the voltage levels in each of such devices and the current flows between the devices.
