Operating model
How BDC works
The approved explanation should connect physical systems, communications, data, security, and operating responsibility.
Bidirectional Charging combines a capable electric vehicle, power-conversion equipment, controls, and safety mechanisms so energy can flow from the grid or building into the battery and back to an external load. It is the enabling power technology for V2G, V2B, and V2H use cases. Actual operation depends on compatible equipment, communications, interconnection approval, and the intended destination for discharged energy.
