FAULT OPERATION STRATEGY FOR PARALLEL BATTERY PACKS

A vehicle includes an electrical load and an electrical system for providing power to the electrical load. The electrical system includes a converter including at least one leg, at least one inductor and a pyro switch between the at least one leg and the at least one inductor, an energy cell coupled to the converter at a first side of the converter, a propulsion cell coupled to a second side of the converter, and a processor. The processor is configured to measure a voltage at a switch of the converter, determine a switch status of the switch based on the voltage, operate the pyro switch to disable the at least one leg that includes the switch, derate a power of the converter to a percentage of a full power of the converter, and provide the derated power to the electrical load.
