SYDNEY: Hyundai Motor Company Australia (HMCA) has completed Australia's first Vehicle-to-Grid (V2G) discharge using the ISO 15118-20 communication protocol, pairing a Hyundai Ioniq 9 with the StarCharge Halo 7.4 kW bidirectional DC charger.
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 (V2H) and Vehicle-to-Everything (V2X) applications.
The StarCharge Halo received Clean Energy Council (CEC) listing in March 2026 and is AS/NZS 4777.2 compliant.
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 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.
HMCA CEO Don Romano said, "This is the result of sustained technical work by Hyundai's research and development 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."
Hyundai models under evaluation or development for V2G in Australia include the Ioniq 9, 5, 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.
Australian Renewable Energy Agency (ARENA) forecasts up to 2.6 million Australian homes could adopt V2G by 2040.
