Abstract

This paper proposes the 10kW class grid connected power station with high discharge current characteristics based on the lithium polymer battery for electric vehicles charger station. The lithium polymer battery has faster discharge current characteristics than that of the conventional battery, so that can compensate high active power demanded by the load in a short time using the low capacity battery bank. Therefore, it is possible to control power leveling of grid by measuring storage energy of battery and active power which is needed from the load. The validity of proposed system was verified through the simulation and experiment.
