The total power of this scheme is 1200kW, equipped with one 1250kVA transformer and 15 charging terminals. The charging power equipment is centrally configured, and multiple charging ports share the charging power. It has the ability to cooperatively control multiple charging ports to charge according to multiple charging strategies. Suitable for fast DC charging and recharging of electric construction vehicles and other vehicles, as well as providing electrical energy for electric buses at large bus stations. In restricted areas of the site, it can meet the power demand for rapid and flexible deployment.
