Utilization of EVs and their used batteries in factory load leveling

The market of electric vehicle (EV) is expected to grow positively in the next few decades replacing the current fossil fueled vehicle. Moreover, as EV market grows rapidly, its secondary used battery is predicted to increase accordingly. To support this growth, wider utilization possibilities for both EV and its used battery have been discussed especially their possibility to take part in the electricity market. Among several services, load leveling in certain energy management system is considered to be one of the excellent candidates. This study focuses on the utilization of EVs and their used batteries to support factory energy management system (FEMS) in term of load leveling. For that purpose, a demonstration test bed has been developed and load leveling test has been performed. From the results, it is shown that application of EVs and their used batteries for load leveling in FEMS is considered feasible.
