Method and apparatus for determining the operational energy cost of a hybrid vehicle

Abstract

A method and apparatus 46 for dynamically and periodically determining the amount of energy expended by a hybrid vehicle 10. Particularly, apparatus or controller 46 dynamically computes the amount of utilized energy based upon the initial charge resident within the battery 14, the amount of power supplied to the battery 14 and the discharge efficiency of the battery 14, thereby allowing an overall energy management strategy to be implemented and allowing an accurate operational analysis and/or simulation to be conducted.
