This Smart EV Charging Station connects multiple parking spaces to monitor and analyse power usage of Electric Vehicle (EV) chargers in real-time, optimising the use of limited power. It provides rated power (100%) when there are only a few EVs. When more EVs are connected, the system can reduce power output of some chargers (e.g. 50%), so as to allocate additional power to the just-arrived vehicles.
The electic power distributed to car park in building is minimal. The electric load capacity for medium / quick charge is generally insufficient at EV charging stations. Retrofitting extra power transformer requires extra space and costs.
