Imagine if your electric vehicle (EV) could not only take energy from the grid—but also give it back. That’s the promise of Vehicle-to-Grid (V2G) technology, a game-changer for Australia’s energy future.
With solar power booming across suburbs and energy prices rising, Australian EV owners have a unique opportunity to play an active role in grid stability and energy management—right from their driveways. Let’s explore how V2G works, its benefits, and what it means for the average Aussie driver.

1. What Is Vehicle-to-Grid (V2G) Technology?
Vehicle-to-Grid (V2G) is a bidirectional energy exchange system that allows an EV to discharge electricity back into the grid. Instead of just drawing power from the grid to charge, your EV becomes a mobile battery that supports the grid during peak demand.
V2G turns your EV into a dynamic energy asset, making it part of the solution to Australia’s energy transition.
Key terms:
- ⚡ Bidirectional charging: Energy flows both ways between your EV and the grid.
- 🏠 V2H (Vehicle-to-Home): Energy powers your home from your EV.
- 🔄 V2G (Vehicle-to-Grid): Energy is exported from your EV to the public grid.

2. How V2G Works in Australia
Here’s how the process typically works:
- You charge your EV at home or work using a V2G-compatible charger.
- Your energy retailer or local grid operator can draw power from your EV when needed (usually during peak hours).
- You get compensated—either through bill credits, time-of-use savings, or direct payments.
- Your EV still reserves enough charge to meet your driving needs.
In Australia, V2G is being trialled in various states including NSW, Victoria, and South Australia, particularly in collaboration with grid operators like AEMO and Ausgrid.
With the growing share of renewables in the National Electricity Market (NEM), V2G can help smooth fluctuations in supply—especially during the evening “duck curve” when solar generation drops off and demand surges.

3. Benefits of V2G for EV Owners and the Grid
✅ Energy Cost Savings
Earn credits or payments by selling excess energy back to the grid during high-demand periods.
✅ Support Renewable Energy
Store solar during the day and export it when it’s most needed, increasing solar self-consumption and reducing reliance on fossil fuels.
✅ Grid Stabilisation
Your EV becomes part of the distributed energy network, helping to balance frequency and voltage.
✅ Blackout Protection (with V2H setup)
Some V2G-capable systems can provide emergency power to your home during outages.
✅ Environmental Impact
Lower reliance on coal- and gas-powered peaker plants by supplementing grid power with clean, stored energy.
For Australians with rooftop solar, combining solar + EV + V2G maximises both energy independence and financial return.

4. V2G-Compatible EVs and Chargers Available in Australia
| Model | V2G Compatibility | Notes |
|---|---|---|
| Nissan Leaf | Yes (CHAdeMO) | Leading the way in Australian trials |
| Mitsubishi Outlander PHEV | Yes (CHAdeMO) | Plug-in hybrid with V2G potential |
| BYD Atto 3 | Planned (V2L only) | V2G expected in future updates |
| Hyundai IONIQ 5/6 | V2L only (for now) | V2G support under development |
Chargers:
- Wallbox Quasar (CHAdeMO)
- Delta DC Wallbox
- JetCharge (Australian provider installing V2G solutions)
Note: Most current V2G systems in Australia use the CHAdeMO standard, limiting compatibility. Wider adoption awaits CCS-based V2G development.

5. Challenges and the Road Ahead for V2G
⚠️ Technical Standardisation
Different connector types (CHAdeMO vs CCS) complicate compatibility. Future-ready models will likely support CCS V2G protocols (ISO 15118).
⚠️ Regulatory Barriers
Energy export approvals, metering standards, and licensing rules vary by state and are still evolving.
⚠️ Battery Warranty Concerns
Frequent cycling for V2G may impact battery life—but many manufacturers are now designing batteries with V2G use in mind.
⚠️ Infrastructure Costs
V2G-compatible chargers and installation are currently expensive. Government rebates may help as adoption grows.
⚠️ Limited Model Availability
Few EVs currently support full V2G, but this is expected to change rapidly as automakers and governments invest in infrastructure.
The Federal Government’s National EV Strategy includes support for smart charging, paving the way for V2G incentives and regulation over the coming years.

FAQs
🔋 Can I use my EV to power my home?
Yes—with V2H (Vehicle-to-Home) setups. You’ll need a compatible EV and bidirectional charger.
📉 Will V2G reduce my battery life?
Minimal impact if managed correctly. Many EVs limit depth-of-discharge for V2G cycles to protect battery health.
⚡ How do I get paid for energy I send to the grid?
Through your energy retailer or VPP (Virtual Power Plant) program—terms vary by provider.
🚗 Is V2G available in all states?
V2G trials are active in NSW, VIC, SA, and ACT. Broader access will depend on policy development and infrastructure rollout.

Conclusion
Vehicle-to-Grid technology is poised to transform how Australians think about energy and transport. Instead of being passive consumers, EV owners can become active participants in the grid—helping stabilise energy, cut costs, and power homes.
🔌 Whether you’re a solar-savvy homeowner or a future-focused fleet manager, V2G offers a powerful way to extract even more value from your electric vehicle.
