Hyundai achieves Australia’s first Vehicle-to-Grid discharge using ISO 15118-20 communication protocol, pairing a Hyundai IONIQ 9 with the StarCharge Halo 7.4 kW bidirectional DC charger.
- HMCA completes its first V2G discharge using the ISO 15118-20 standard with a Hyundai IONIQ 9 and StarCharge Halo charger
- First ISO 15118-20 V2G discharge completed with the StarCharge Halo in Australia
- Milestone supports HMCA’s commitment to manufacturer-approved, standards-compliant V2G deployment
Vehicle-to-Grid
ISO 15118-20 is the second-generation international standard for bidirectional power transfer between electric vehicles and charging equipment. It provides the secure, interoperable framework required for V2G, Vehicle-to-Home and Vehicle-to-Everything applications.
The StarCharge Halo received Clean Energy Council (CEC) listing in March 2026 and is AS/NZS 4777.2 compliant.
Standards-compliant V2G on the IONIQ 9
The IONIQ 9 is built on Hyundai’s Electric-Global Modular Platform (E-GMP) with 800-volt architecture designed for high-power DC charging and bidirectional energy flows. This milestone confirms that local V2G software enablement and certification is progressing in 2026.
Supporting future residential V2G trials
This milestone highlights Hyundai’s leadership in bringing an ISO 15118-20-enabled vehicle platform to Australia. With the IONIQ 9, Hyundai is helping establish a standards-based pathway for scalable, manufacturer-supported V2G and V2X deployment across homes, buildings, energy networks and virtual power plants.
Don Romano, Chief Executive Officer of HMCA, said:
“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.
“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.”
Austin Luo, Director eMobility, StarCharge Energy Oceania, said:
“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 7.4 kW bidirectional DC charger. And we look forward to working with industry partners. To accelerate standards-compliant, manufacturer-supported V2G adoption across Australia.’”
V2G roadmap
Hyundai models under evaluation or development for V2G in Australia include the IONIQ 9, IONIQ 5, IONIQ 6 and future IONIQ platforms. Globally, Hyundai Motor Group is advancing V2X capabilities through Korea’s first customer-focused V2G pilot. On Jeju Island, commercial V2G services in Europe and V2H services in the United States.
Australia adopted national V2G and V2H standards in 2024. ARENA forecasts up to 2.6 million Australian homes could adopt V2G by 2040. HMCA encourages all stakeholders to ensure V2G programmes utilise manufacturer-approved technology compliant with ISO 15118-20.
