Hyundai completes Australia’s first standards-compliant V2G discharge

Hyundai Motor Company Australia has completed what it says is Australia’s first Vehicle-to-Grid (V2G) discharge using the latest international standard (ISO 15118-20).

The demonstration paired a Hyundai Ioniq 9 with a StarCharge Halo 7.4kW bidirectional DC charger.

ISO 15118-20 is the latest international standard governing bidirectional energy transfer between electric vehicles and charging equipment, providing the framework for V2G, Vehicle-to-Home (V2H) and Vehicle-to-Everything (V2X) applications.

Hyundai says the milestone demonstrates progress towards manufacturer-approved, standards-compliant V2G deployment in Australia.

The Ioniq 9 is built on Hyundai’s Electric-Global Modular Platform (E-GMP) and features an 800-volt electrical architecture designed to support high-power charging and bidirectional energy flows.

Hyundai Motor Company Australia chief executive Don Romano says the achievement is the result of extensive development work by Hyundai’s engineering teams.

“This is the result of sustained technical work by Hyundai’s R&D teams in Korea and Australia. ISO 15118-20 includes all the messages and sequence requirements for bidirectional power transfer.

“Getting this right is essential because V2G will only scale in Australia if consumers, energy providers and governments can trust the technology.”

Romano says electric vehicles have the potential to play a much larger role in the energy system.

“Electric cars can do far more than just drive. They can power homes and support the grid.

“This first V2G discharge using ISO 15118-20 with the IONIQ 9 demonstrates that we are delivering real innovation, not just talking about it.”

The StarCharge Halo charger used in the demonstration received Clean Energy Council approval in March 2026 and complies with AS/NZS 4777.2 requirements.

Austin Luo, director of eMobility at StarCharge Energy Oceania, says the project marks an important step for Australia’s emerging V2G market.

“This is an important milestone for Australia’s V2G market and a strong demonstration of Hyundai’s leadership in bringing ISO 15118-20-enabled vehicle technology to Australia through the IONIQ 9.

“StarCharge is proud to support Hyundai with the StarCharge Halo 7.4kW bidirectional DC charger, and we look forward to working with industry partners to accelerate standards-compliant, manufacturer-supported V2G adoption across Australia.”

Hyundai says the milestone will support future residential V2G trials and broader deployment of vehicle-to-grid technology across homes, buildings, energy networks and virtual power plants.

The company is evaluating V2G capability for the Ioniq 9, Ioniq 5, Ioniq 6 and future Ioniq models in Australia.

Australia adopted national V2G and V2H standards in 2024, with the Australian Renewable Energy Agency forecasting up to 2.6 million homes could adopt V2G technology by 2040.
