Management information system of charging station for electric vehicle (EV)

The actual problems and requirements of charging station, especially for electric vehicle, are analyzed. This paper presents the design and implementation of a fully digital smart management information system of charging station for EV, which has been already installed in Xihuangzhuang bus-station of Beijing. The collected data show that the system can be easily applied to shift the charger to the optimum charging pattern as function of ambient temperature, voltage, current and time of day, which makes for short charge times, high charge efficiencies and improved battery cycle life. Furthermore, the system facilitates the charging station workers and the customers.
