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.

Claims

1. A process for transferring electrical energy from a first electrical energy storage device to a second, rechargeable electrical storage device, comprising the steps of sensing the voltage in said first electrical energy storage device, sensing the voltage in said second electrical energy storage device, determining the difference in the voltages in said first and said second electrical energy storage device, flowing current from said first electrical energy storage device to said second electrical energy storage device, adjusting the rate of current flow from said first electrical energy storage device to said second energy storage device by means of a controller, providing power to said controller by means of a switch that switches the power supplied to the controller from said first electrical energy storage device to said second electrical energy storage device, and from said second electrical energy storage device to said first electrical energy storage device, and means for insuring that said voltage in said first electrical energy storage device is higher than said voltage in said second electrical energy storage device.

2. The process as recited in claim 1, wherein said first electrical storage device is a battery.

3. The process as recited in claim 2, wherein said second electrical storage device is a rechargeable battery.
