Abstract
A method is provided for achieving a constant driving range in an electric vehicle over a multi-year period (e.g., 5, 8, 10 years), where the preset driving range corresponds to a percentage of the driving range that is achievable with the initial battery pack capacity. Prior to each charge cycle, the method first determines the current battery pack capacity and then determines a set of optimized charging parameters based on the current battery pack capacity and the preset driving range. Charging is then performed in accordance with the set of optimized charging parameters.
