Recently, saving energy of power mechatronic machines is an important theme because the global warming becomes a serious problem. In particular, the saving energy of the electric vehicle is important. This paper discusses the energy saving method of the electric vehicle of which the energy is regenerated. Evaluation function is made from the weighted sum of the dissipated energy and comfortable ride (jerk). Using optimal control theory, we find optimal velocity and current functions which minimizes the evaluation for various weights α. Then, we examine the dissipated energy and the comfortable ride for various α.
