V2H and V2G let your car's battery power your home or the grid. It's the next frontier of home energy.
The idea
Modern EVs carry large batteries — often far bigger than a home battery. Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) technologies let that battery work for more than driving: it can power your home or feed energy back to the grid.
Vehicle-to-Home (V2H)
V2H lets you discharge your EV's battery to run your home — during an outage, during the evening peak, or whenever it's cheaper than grid power. Your car becomes a backup power source.
Vehicle-to-Grid (V2G)
V2G goes further: your car can export energy to the grid during high-demand, high-price periods, earning you money — similar to a VPP but using the car's battery.
What you need
- A compatible EV with bidirectional charging capability.
- A compatible bidirectional charger.
- The right electrical setup and (for V2G) a network agreement.
Where it's at
V2H and V2G are emerging in Australia. A small but growing number of vehicles and chargers support it. If you're planning an EV and energy system today, choosing V2H/V2G-ready hardware keeps the door open.
The takeaway
Your next car may be one of the biggest batteries in your energy system. Planning for V2H/V2G now means you won't have to rewire later.
