PV-Storage-Charging EMS
PV, storage, and charging-load coordination for stations
For PV carports, fast-charging stations, and park charging sites, focusing on charging-load peaks, transformer capacity, storage peak shaving, and station energy flow.
EMS SOLUTION
Solution Overview
EMS SOLUTION
Customer Pain Points
Charging load fluctuates sharply
Vehicle charging can raise station power quickly and create peaks.
Transformer capacity is under pressure
Fast-charging scenarios raise requirements for distribution capacity and grid access.
PV, storage, and chargers are hard to coordinate
Independent operation makes station-level energy strategy difficult.
Storage is needed during charging peaks
Storage support must be visible when peak shaving is expected.
Energy cost and charging service both matter
Operators need to balance cost and charging availability.
Integrated operation view is missing
Charging orders, charging power, PV output, and storage power need one view.
EMS SOLUTION
Solution Description
PV-storage-charging EMS is not just PV-storage monitoring. It brings EV charging power, PV output, storage dispatch, station load, and grid-point power into one station energy-flow view.
The system focuses on charging-load peaks and transformer capacity pressure, helping review how storage supports peak shaving during charging peaks and absorbs PV output during high-generation periods.
Operators can view charging service capability, energy cost, storage operation, and PV consumption together for station energy strategy review.
