Abstract
An information handling system includes a power assist unit (PAU) and a baseboard management controller (BMC). The PAU is coupled to a power rail and includes a power storage element, a converter coupled to the power storage element and the power rail, and a controller. The controller receives a current level indication indicating a current provided to a load of the information handling system, directs the converter to provide power from the power storage element to the power rail when the current level indication is greater than a threshold level, directs the converter charge the power storage element from the power rail when the current level indication is greater than the threshold level, and provides a charge level indication that indicates an amount of charge on the power storage unit. The BMC receives the charge level indication, and sets a peak power limit for the information handling system based on the charge level indication.
