What is V2G?
V2G stands for vehicle-to-grid. It describes a system where an electric vehicle can send electricity from its battery back to the electricity grid. This requires a compatible EV, bidirectional charger, energy management system and grid-approved setup.
V2G is different from standard charging because the vehicle becomes a two-way energy asset rather than just an electricity user. When managed properly, many parked EVs could help support the grid during peak demand or periods of low supply.
Why V2G matters
V2G could allow EV owners to earn value from their battery, support renewable energy integration and help stabilise the electricity network. However, it is more complex than normal charging and depends on technology, regulation, electricity tariffs and battery warranty considerations.
On Penguin Power, V2G is useful for readers exploring the future of EV charging and energy. It is closely linked to smart charging, bidirectional charging, home energy systems and grid services. It is not the same as V2L, which is usually about powering devices directly from a vehicle.
