Vehicle-to-Grid (V2G) Explained: The Future of EV Charging
V2G technology lets your EV send power back to the grid, potentially earning you money. Here's what you need to know about this emerging technology.
What is Vehicle-to-Grid (V2G)?
V2G is bidirectional charging technology that allows your EV to not only draw power from the grid but also send stored energy back. Your car essentially becomes a mobile battery that can power your home or feed electricity back to the grid.
How Does V2G Work?
V2G requires three components:
- A V2G-compatible electric vehicle
- A bidirectional charger
- An energy management system
The charger communicates with both your car and the grid (via your energy supplier) to manage when to charge and when to discharge.
Potential Benefits
- Earn money: Sell electricity back during peak demand periods
- Reduce bills: Use stored energy instead of buying from grid
- Grid stabilisation: Help balance supply and demand
- Backup power: Power your home during outages
Current V2G Compatible Vehicles
V2G requires CHAdeMO connector (used by some Japanese EVs) or compatible CCS. Currently compatible vehicles include:
- Nissan Leaf (with CHAdeMO)
- Nissan e-NV200
- Mitsubishi Outlander PHEV
More CCS-based V2G vehicles are expected from European manufacturers.
V2G Chargers Available
- Indra Smart Pro - V2G ready
- Wallbox Quasar - V2G capable
- Various commercial units
Is V2G Worth It Now?
V2G is still emerging technology. Consider it if:
- You have a compatible vehicle
- You want to future-proof your installation
- You're enthusiastic about the technology
For most buyers, a smart charger with solar integration offers similar benefits with broader compatibility.
