Abstract
A system for reducing overdraw of power in a vehicle includes a power source having a battery and a fuel cell circuit. The system further includes an ECU that transmits a power limit signal to a vehicle controller, the power limit signal corresponding to an instantaneous maximum amount of power of the power source. The ECU also determines a battery allowed power corresponding to an amount of power available to be drawn from the battery to cause the SOC of the battery to remain above a lower SOC threshold. The ECU also determines a current battery power draw from the battery corresponding to an instantaneous amount of power being drawn from the battery. The ECU is designed to reduce the instantaneous maximum amount of power in the power limit signal when the current battery power draw is greater than the battery allowed power, reducing the current battery power draw.
