Electric Vehicle Charging Navigation Strategy Considering Multiple Customer Concerns

摘要

This paper proposes a platform that supports the electric vehicle (EV) to navigate to a proper station for charging. This platform considers several important factors, concerns, that influence the selection of a suitable charging station. These factors are the energy consumption in driving to reach the charging station from the EV location, the demanded charging energy, the parking time to start charging at the charging station, the extra time in charging due to lowering the charging power rate at the charging station pole, and the energy consumption in driving to reach the EV target destination after charging at the charging station. These factors are represented by their costs and formulated as a cost function for charging the EV. This formulation is constructed for each EV to facilitate the distributed implementation of this charging navigation platform. The problem is then solved in an optimal way for selecting the charging station. Several comparison methods are introduced and the advantage of the proposed strategy is demonstrated to lower the cost paid by the customer to charge the EV during his/her travel mobility plan.
