Development of Battery and Charger Integration System (BCIS) for EV charging stations

The popularization of electric vehicles (EVs) will give rise to challenges that include expenses for capacity upgrades, power supply shortages, and long waiting time to charge. We have therefore developed a Battery & Charger Integration System (BCIS) to support the burgeoning infrastructure for EVs. The system enables charging time reductions in simultaneously multiple EVs charging by shifting the charging power peak and using power of stationary batteries. This paper outlines the BCIS and the results of an experiment and simulation of charging time reductions.
