FUEL CELL/BATTERY HYBRID SYSTEM HAVING BATTERY CHARGE-LEVEL CONTROL

摘要

PATENT APPLICATION PAPERS OF J. WERTH and I. FEKETE FOR: FUEL CELL/BATTERY HYBRID SYSTEM HAVING BATTERY CHARGE-LEVEL CONTROL A fuel cell/battery hybrid power system is disclosed which has a microprocessor based control system. The control system enables the fuel cell to be taken out of the system by a switch when its predetermined maximum desired energy output is about to be exceeded by load requirements. The batteries are protected from overdischarge through a switch and the surge battery is selected by the battery having the highest level of charge at any given time.
