Power quality analysis and harmonic suppression of high latitude and high alpine region electric vehicles charging station

In China, the first electric vehicles charging station of high latitude and high alpine region was built in Heilongjiang Electric Power Research Institute. In this research, electric vehicles charging station was introduced including a 100 kW DC charger and the main circuit diagram of EV charging station. In order to improve power quality and suppress harmonic, a shunt active power filter was applied in the EV charging station. To verify the effect of the shunt active power filter, charging experiments under different current for a bus were undertaken.
