Abstract
A method for estimating an operating life for an electrical energy storage system electrically connected to transmit power to a hybrid powertrain system includes monitoring temperature state-of-charge and electric current of the electrical energy storage system, calculating a battery life metric for a time interval based upon the temperature, the state-of-charge, and the electric current discharge, determining a total battery life metric therefrom and determining the remaining operating life of the electrical energy storage system.
