Information
Definition
Vehicle-to-Home allows an EV to supply energy to a home through compatible bidirectional charging equipment and electrical controls. It is normally assessed alongside vehicle compatibility, export permissions, grid connection requirements and the supported communication standards.
Why it matters
It may help households use stored vehicle energy, but it needs compatible vehicles, chargers, protection and UK electrical design consideration. For UK users, it affects future energy services, vehicle compatibility, grid connection requirements and potential export value.

ISO 15118
ISO 15118 is the international vehicle-to-grid communication standard series covering EV-to-charger digital communication, Plug & Charge, smart charging and bidirectional charging functions. In the UK it is increasingly relevant to future-ready public, fleet and V2G-capable charging systems.
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.
