BEIJING, Aug. 30 (Xinhua) -- A self-adaptive electric vehicle (EV) charging station built by State Grid in the Qinglian Street Park in Quanzhou of southeast China's Fujian Province has been put into operation recently.
Integrating photovoltaic power generation, energy storage and charging, the EV charging station can provide charging services simultaneously for 20 new energy vehicles (NEVs) at most.
With energy router technology, the EV charging station can not only meet the plug and play demand of high-power NEVs in large scale, but also provide flexible support for power grid load, achieving self-adaptive balance between EV charging load and power grid load.
The multi-port energy router system adopted by the EV charging station is equivalent to a power grid energy regulation hub which can improve the energy conversion efficiency by about 5 percent, store excess energy, effectively suppress the impact of large-scale high-power charging on the power grid, and relieve the power supply pressure during peak hours of electricity consumption through flexible regulation of charging load.
In case of power grid malfunction or heavy overload, the energy router can also provide emergency power supply for the adjacent Xunmei Village to secure the electricity quality for nearby residents.
