Patent CA-2275041-A1 (CA)
Inventor: BERNARD BRUCE
IPC: H02J50/10
Filed: 1999-06-17
Abstract: The invention consists of an electrical power system for an electronic apparatus, such as a cordless telephone, which includes a base unit and a portable unit.  The base unit normally derives power from an external power source. The base unit includes a rechargeable battery pack for use when the external power source fails. The portable unit is powered by a rechargeable battery pack. When the external power source fails, both the base unit and the portable unit continue operation, powered by their respective battery packs. If the portable unit battery pack energy level falls below a minimum threshold level, the base unit can act to transfer energy from the base unit battery pack to the portable unit battery pack. The system thereby maximizes the apparatus operation time while the external power source is failed by optimizing the distribution of energy between the respective units.
