Beschreibung
Zusammenfassung:	A fault management method and device for a hybrid power system having multiple fuel cells. The method comprises: obtaining a main state value of the hybrid power system; obtaining a health state value of the hybrid power system at a current moment; the main state value and the health state value representing power supply states of the hybrid power system at different moments, and the power supply states being determined by a power supply topological structure formed by batteries, capable of supplying power to the outside, in the hybrid power system; and executing, according to the two power supply states corresponding to the main state value and the health state value, fault processing programs corresponding to the two power supply states, and controlling a bypass isolation switch according to the fault processing programs.
