Standard or regulation
ENA EREC G100
ENA EREC G100 is the UK Engineering Recommendation for customer export and import limitation schemes used to control power flow at a grid connection point. In EV charging it is relevant to load management, constrained connections, V2G export control and maximum import limitation.
E
ENA Connect Direct V2G
ENA Connect Direct V2G relates to ENA connection data for vehicle-to-grid capable equipment.
ENA Connect Direct V2G Stack
ENA Connect Direct V2G Stack refers to the broader approved or declared combination of V2G charger, inverter or control system and associated equipment used for connection assessment.
L
Load Curtailment
Load curtailment reduces or temporarily limits charging demand to keep a site within an agreed electrical capacity or operating limit. It is normally assessed against site capacity, maximum demand, charger grouping and the behaviour expected when electrical demand changes.
V
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.
