ABSTRACT:
A refresh control system that selectively initiates a refresh charge cycle includes an energy storage device and an electric machine that is operable to charge the energy storage device. A control module monitors a usage period of the energy storage device and determines a bias factor. The control module determines a modified usage period threshold based on a usage period threshold and the bias factor. The control module regulates the electric machine to initiate a refresh charge cycle of the energy storage device when the usage period exceeds the modified usage period threshold.
