A hybrid system including a hybrid control module for operating the hybrid system to as to have its energy storage device meet a predetermined service life metric is disclosed. The hybrid control module stores experimental information indicative of the impact of certain usage parameters on the service life of the energy storage device, monitors the actual usage parameters observed during operation of the hybrid system, and dynamically determines a maximum operating temperature for the energy storage device in order to increase or decrease its utilization by the hybrid system.
