Abstract
An embodiment of the invention provides a method of charging an energy storage system for an electric vehicle. The method includes determining the estimated consumption for a specific route of the electric vehicle at different times and setting a target end point for the energy storage system based upon a minimum state of charge level for the energy storage system. The method further includes determining charge set points for the energy storage system based upon the target end point and the determined estimated consumption and determining the actual end point of the energy storage system after operation of the electric vehicle on the given route. The method also includes comparing the actual end point to the target end point and determining the difference in state of charge for the energy storage system between the actual end point and the target end point. In addition, the method includes using the difference between the actual end point and the target end point to adjust the charge set points for the energy storage system.
