Abstract
A system and method for increasing the available energy and system runtime of battery powered electric devices which use non-rechargeable cells as an energy source. The present invention employs techniques for using energy from both rechargeable and non-rechargeable batteries in a manner which discharges each of the different cells within their optimal discharge rate. In particular, the non-rechargeable batteries are used for a low rate of system discharge and rechargeable cells supplement the non-rechargeable batteries for a higher system loads. In a preferred embodiment of the present invention, when the system load is at a very low level, the rechargeable battery is recharged using power from the non-rechargeable battery. The result of the techniques of the present invention is the lowering of discharge rate and hence increasing the capacity of the non-rechargeable cell.
