A system for derating a power limit associated with a battery pack is provided. The system includes a battery pack voltage sensor that measures a first battery pack output voltage of the battery pack at a first time, and a microprocessor that determines an initial power limit of the battery pack based on at least one operational parameter of the battery pack. The microprocessor further determines whether the first battery pack output voltage is greater than a threshold battery pack voltage. The microprocessor further determines a first power limit of the battery pack that is less than the initial power limit, if the first battery pack output voltage is greater than the threshold battery pack voltage.
