V2L, V2H and V2G
Using the car as a power station.
You'll learn
- Explain v2l, v2h and v2g clearly and accurately
- Read the numbers that define the behaviour
- Apply the idea to a real charging session
Overview
A 70 kWh pack holds several days of household electricity. Bidirectional charging turns that into a usable resource.
In depth
Bidirectional modes
| V2L | V2H | V2G | |
|---|---|---|---|
| Output | Domestic socket, 2–3.6 kW | House circuits, 6–11 kW | Grid export, 7–11 kW |
| Extra hardware | Adapter only | Bidirectional charger and changeover switch | Bidirectional charger and grid agreement |
| Main benefit | Tools and camping | Backup power | Tariff arbitrage and grid services |
Key takeaways
Remember this
- V2L is available today with only an adapter.
- V2H needs a bidirectional charger and switchgear.
- V2G pays only if it beats the degradation cost.
