Abstract
A method is provided for optimizing the charging protocol used when charging the battery pack of an electric vehicle, where optimization is based, in part, on the user's intended departure time and intended travel distance. Based on the user's travel information the process determines (i) an optimal charge level that maximizes the battery pack's lifetime while assuring that there is sufficient energy for the vehicle to travel the intended distance and (ii) an optimal charging rate that maximizes the battery pack's lifetime while assuring that the battery pack is charged to the optimal charge level prior to the intended time of departure. Safety margins may be added to the user's travel information, thus insuring that the car is charged and ready for use if the user decides to leave earlier than expected, or if the travel takes a larger charge than expected.
