'EVs as Backup Batteries': Hyundai Motor Group Launches V2G Pilot Service on Jeju Island

"Mobile ESS" for Storing and Supplying Electricity

It has become possible to use electric vehicles as "wheeled backup batteries" on Jeju Island.

Hyundai Motor Group announced on May 15 that it will conduct a pilot service for 'V2G (Vehicle-to-Grid)' technology for general customers on Jeju Island. V2G is a technology that connects electric vehicle batteries to the power grid, allowing electricity to flow in both directions. This enables energy to be stored and shared bidirectionally at any time through electric vehicles.

Hyundai Motor Group has been operating the V2G pilot service in collaboration with the mobility platform SoCar on Jeju Island and will expand the service to include Jeju residents.

The company selected forty Jeju residents who own either a Hyundai Ioniq 9 or Kia EV9—models equipped with V2G technology—and who are able to install a V2G bidirectional charger at their home or workplace.

To verify a variety of usage patterns, Hyundai Motor Group conducted on-site inspections and selected the final participants by evenly distributing them across different occupations and places of residence. In addition, the company will install the bidirectional chargers free of charge and cover the entire cost of electric vehicle charging during the pilot service period.

Participants will use their electric vehicles not just as a means of transportation that charges in one direction, but as "mobile energy storage systems (ESS)" that can store and supply electricity.

This is expected to shift the energy industry structure from one centered on power plants to a regionally based, self-sustaining economic model. Since Jeju Island relies heavily on wind and solar power, surplus electricity produced during the day can be stored in electric vehicles and then sent back to the grid at night—maximizing both the utility and economic value of renewable energy.

Hyundai Motor Group plans to accelerate the creation of a domestic V2G ecosystem and the activation of related industries through the expansion of this pilot service. A company representative stated, "We expect the V2G pilot service, which involves actual Jeju residents, will support the realization of local energy production and consumption within Jeju Island," adding, "It will also play a key role in achieving Jeju Island's vision for carbon neutrality by 2035."
