From 2027 onwards, a lot will change for households with solar panels or an electric car. The net metering scheme will disappear and the feed-in tariff will become less favourable. But for smart drivers with an electric car, there is an opportunity: bidirectional charging . This changes your EV from a means of transport into an energy manager. In this article, we explain what bidirectional charging is, what will change in 2027 and – most importantly – how you can benefit financially from it.
What is bidirectional charging?
With traditional charging, you simply charge your electric car via a charging station. With bidirectional charging, it works both ways: you can not only charge power into the battery, but also supply power from the battery back to your home or the electricity grid. Your car then becomes a mobile home battery .
Bidirectional charging is possible thanks to technologies such as:
- V2G (Vehicle-to-Grid): you supply back to the energy grid
- V2H (Vehicle-to-Home): you power your home
- V2B (Vehicle-to-Building): you support a (company) building
Some models from brands like Hyundai, Kia, Nissan, and MG already support this technology. And the number of suitable vehicles is growing rapidly.
Feed-in tariff in 2027: what will change?
The government is abolishing the current netting scheme, which until now allowed you to feed in 1-on-1. Instead, you will receive a lower feed-in compensation from your energy supplier, often only a fraction of the kilowatt-hour price you pay when you consume.
What does this mean to you?
- Feeding back into the grid yields less
- Storing your own electricity is becoming more interesting
- Smart consumption control (such as with your EV) becomes profitable
Bidirectional charging makes it possible to use your own generated power at times when your energy is most valuable .
This is how smart return via your electric car works
With bidirectional charging, you can charge your car with solar energy during the day and use that power at home in the evening – or feed it back into the grid during peak rates. Combine this with a dynamic energy contract , and you earn money on your timing:
- Charge cheaply when the electricity price is low (for example at night or when there is a lot of sun/wind)
- Return when the price is high (for example in the evening when demand is high)
Result: lower costs and possible returns.
Getting maximum benefit: smart charging solutions
To benefit from bidirectional charging, you need a suitable charging station . Please note:
- The charging station must be able to charge bidirectionally (V2G/V2H support)
- You may need a CCS or CHAdeMO connector depending on your car
- Smart energy control via apps or load balancing system helps you switch optimally between charging and supply

Is your car suitable for bidirectional charging?
Not every EV supports this technology. Some examples that do:
- Hyundai IONIQ 5 / 6
- Kia EV6
- Nissan Leaf (with CHAdeMO)
- MG ZS EV (some models)
Many brands are expected to switch to V2G standards in 2025-2027, so check if your next EV supports it.
Not yet suitable? Then you can already invest in a future-proof charging station , so that you are ready for it later.
Future of bidirectional charging
The energy transition requires smart storage and use of energy. Governments and grid operators are investing in pilots for bidirectional charging. This means:
- More support for EV feed-in
- Dynamic rewards based on energy market prices
- New possibilities to make your car part of a local energy grid

Frequently asked questions about bidirectional charging
- What is the difference between V2G and V2H?
- V2G supplies back to the grid; V2H supplies your home directly. V2H is ideal for dynamic tariffs or for energy autonomy.
- Does bidirectional charging affect my battery?
- When used correctly, the impact is minimal. Many EVs are specifically designed for this.
- Do I need a special charging station?
- Yes, standard chargers are not bidirectional. You need a V2G compatible charging station and a car that supports it.
- Can I also benefit without solar panels?
- Sure! Even without your own generation, you can charge smartly at low rates and return at high rates.
