Vehicle-to-Grid Technology: Connecting EVs to the Power Grid

Discover how vehicle-to-grid (V2G) technology enables electric vehicles to do more than consume electricity. Through bidirectional charging, EV batteries can store energy, return electricity to the grid and support a more flexible energy system.

Understanding the technology

What Is Vehicle-to-Grid (V2G)?

Vehicle-to-grid is a bidirectional energy technology that allows compatible electric vehicles to exchange electricity with the power grid. Instead of treating an EV only as an electricity consumer, V2G can make its battery part of a wider energy system.

Bidirectional charging

Electricity can flow from the grid to a compatible EV battery and, when authorised, from the vehicle back to the grid.

Grid flexibility

Aggregated EVs may help shift electricity demand, support grid services and provide flexibility during periods of high or changing demand.

Renewable integration

Coordinated EV charging and discharging can help align electricity use with renewable generation, depending on local grid conditions and market rules.

Why vehicle-to-grid matters

Potential Benefits of V2G Technology

The value of vehicle-to-grid depends on compatible vehicles, bidirectional charging equipment, electricity market access, grid conditions and customer participation.

Demand balancing

Coordinated charging and discharging may help balance electricity demand and reduce certain network peaks.

Renewable energy

Flexible EV charging can help make better use of available solar and wind generation.

Energy flexibility

Compatible EVs can become flexible energy resources for homes, fleets, buildings and electricity systems.

New market services

Aggregated EV capacity may participate in eligible flexibility and grid-service markets.

Related technologies

V2G, V2H, V2B and Smart Charging

Bidirectional charging includes several related approaches. Understanding the differences helps explain where energy flows and who or what receives the electricity.

Vehicle-to-Grid (V2G)

Electricity can flow from a compatible electric vehicle back into the electricity grid to support eligible grid services and energy-market applications.

Vehicle-to-Home (V2H)

An EV can supply electricity to a home, potentially supporting household energy use or backup power when the system is designed for that purpose.

Vehicle-to-Building (V2B)

A compatible EV can provide energy to a commercial or institutional building, subject to system design and electrical installation requirements.

Smart charging (V1G)

Charging power is controlled to respond to schedules, electricity prices or grid signals. Traditional V1G smart charging does not export energy from the vehicle.
