Terms beginning with V in Bidirectional Charging category referencing ENA EREC G99
Standard or regulation
ENA EREC G99
ENA EREC G99 is the UK Engineering Recommendation for connecting generation equipment and larger power generating facilities in parallel with public distribution networks. It is relevant to export-capable EV charging, V2G, storage and larger schemes that do not fall under G98.
V
Vehicle-to-Building (V2B)
Vehicle-to-Building allows an EV to supply energy to a building or site load through compatible bidirectional charging equipment. It is normally assessed alongside vehicle compatibility, export permissions, grid connection requirements and the supported communication standards.
Vehicle-to-Everything (V2X)
Vehicle-to-Everything (V2X) is an umbrella term for bidirectional EV charging use cases where energy can flow from the vehicle to another load, building, home, grid or wider energy system. It includes V2G, V2H, V2B and V2L depending on the destination of the exported energy.
Vehicle-to-Grid (V2G)
Vehicle-to-Grid allows an EV to export energy back to the electricity grid or support grid services through compatible charging equipment. It is normally assessed alongside DNO requirements, import/export limits, generation, storage and wider site energy management.
