Abstract

An electric vehicle (EV) quick charger based on CHAdeMO standard with grid-support function is proposed in this paper. The current source modular converter configuration is used to perform the charging pulses with both positive and negative pulse to achieve required time for an EV which is less than 30 minutes. The use of current source converter can offer the inherit fault tolerance capability and bidirectional power flow. CHAdeMO protocol is modified for grid-support function. The 50 kW prototype is developed to validate the proposed notion. The simulation and experimental results illustrate that the proposed pulse frequency charging technique requires about 16 minutes to fully charge of the battery from 20% of SOC to 80% of SOC. The results suggest that the proposed technique can be applied for an electric vehicle quick charger station.
