Abstract
A system for reducing overconsumption of power in a vehicle includes a power source including a battery having a state of charge (SOC), and a fuel cell stack that generates electricity. The system further includes an electronic control unit (ECU) coupled to the power source and designed to receive a power request corresponding to a requested amount of power from the power source. The ECU is further designed to determine a fuel cell power amount corresponding to an amount of the electricity generated by the fuel cell stack to achieve the requested amount of power. The ECU is further designed to determine an overconsumption event when a current power consumption corresponding to a total amount of power being drawn from the power source is greater than the power request. The ECU is further designed to increase the fuel cell power amount in response to determining the overconsumption event.
