With the increasing number of electric vehicles (EVs), the out-of-order random charging behaviors cause the smart grid overload and the battery depreciation. Despite the fact that a lot of research has focused on EV charging coordination, it remains unexplored how to coordinate the EV charging while maximizing the convenience of EV drivers and minimizing the battery depreciation, which is a vital to the improvement of service quality of the charging station and the users' satisfaction, since the convenience and lifetime of battery are specially concerned by EV drivers. In this paper, we systematically studied the problem and a real-time charging scheme was proposed to coordinate the electric vehicle (EV) charging and decrease the battery depreciation. To prevent private leak and decrease calculation complexity, an ADMM-based distributed method was proposed. Extensive evaluations show that our distributed optimization method brings significant cost savings over existing methods. Simulation results show that the proposed algorithm could reduce the price cost of EV drivers and battery lifetime depreciation by up to 18.3% and 33.0% respectively.
