V2G, which can turn EVs into giant home batteries, is coming to some cars in 2025 - ABC News
Summary:
Vehicle-to-grid (V2G) technology, which allows electric vehicles (EVs) to act as home batteries and export energy to the grid, has cleared key regulatory hurdles in Australia. This paves the way for EV owners to save on energy bills and potentially earn income by selling power back to the grid. While federal authorities predict V2G will become a reality by Christmas, experts suggest widespread availability of V2G chargers is unlikely until mid-2025.
Key points:
- EVs with large batteries (50–100kWh) can help households store solar power and reduce reliance on the grid. Early adopters have seen savings and earnings of $1,000–$2,000 annually.
- Regulatory delays and technical challenges have slowed V2G adoption, but updates to standards now enable the certification of chargers.
- Most current EVs don’t support V2G, with only older CHAdeMO plug models (like the Nissan Leaf) currently compatible. Future V2G chargers will use the newer CCS2 standard, awaiting approval.
- Manufacturers are working on V2G capabilities, with V2G-ready EVs expected from 2025.
- Experts believe V2G will eventually become widespread, similar to rooftop solar, offering significant grid support and household savings.
While the transition to V2G will take time, the technology is seen as a major opportunity to manage energy supply and demand while reducing costs for EV owners.
