Everything about Vehicle-to-Home technology. Which EVs support V2H, what does it cost, and how does it compare to a fixed batteria domestica?
With ricarica bidirezionale, your auto elettrica can not only absorb elettricità, but also feed it back to your home. This is called Vehicle-to-Home (V2H). Your EV batteria of 40–100 kWh effectively becomes a massive batteria domestica — many times larger than a fixed batteria domestica of 5–15 kWh. The concept is simple: charge your car during the day with energia solare and use that elettricità in the evening to power your home.
V2H is becoming increasingly practical in 2026 thanks to more compatible cars, more affordable bidirectional chargers and improved EU regulations. Tuttavia, there are important caveats — your car is not always at home, and the additional cicli di carica affect the batteria's lifespan.
Not every EV can charge bidirectionally. The car must contain specific hardware, and the produttore must enable V2H functionality via software. In 2026, the following models support V2H:
For V2H, you need a special bidirectional charger. A standard wallbox (AC charger) only works in one direction. Bidirectional chargers operate on DC (direct current) and cost considerevolmente more:
| Marca/Modello | Protocol | V2H output | Availability NL |
|---|---|---|---|
| Nissan Leaf (40/62 kWh, compatibile V2H) | CHAdeMO | 6 kW | Disponibile ora |
| Hyundai Ioniq 5 | CCS | 3.6 kW | Disponibile ora |
| Kia EV6 | CCS | 3.6 kW | Disponibile ora |
| BYD Atto 3 | CCS | 3.3 kW | Limitato |

Please note: the bidirectional charger must be compatible with your car and your home installazione. Not every combination works. Always seek advice from a installatore certificato.
V2H has clear pros and cons compared to a fixed batteria domestica:
The key question: is V2H a good alternative to a fixed batteria domestica? That depends on your situation. Here is an honest comparison:
| Criterio | V2H (car as batteria domestica) | Fixed batteria domestica |
|---|---|---|
| Capacità | 40–100 kWh | 5–20 kWh |
| Availability | Only when the car is at home | Available 24/7 |
| Lifespan impact | Additional degradazione della batteria | No impact on other devices |
| Cost (charger/batteria) | €3.000–6.000 | €1.500–8.000 (5–20 kWh) |
The conclusion is nuanced: V2H offers enormous storage capacità, but a fixed batteria domestica is more reliable and always available. The ideal situation? Both: a batteria domestica for daily storage and V2H as an additional buffer for peak consumption or emergency power.
The costs for a V2H installazione are still considerable in 2026. The bidirectional charger costs €3,000–6,000 including installazione. On top of that, your car must be compatible — and those cars are often more expensive than models without V2H support.
The periodo di ammortamento for V2H alone (excluding the car itself) is 8–12 years, assuming you have the car at home daily and actively use V2H. By comparison: a fixed batteria domestica of 10 kWh has a periodo di ammortamento of 5–8 years and is much simpler to install.
V2H is a promising technology that will become increasingly accessible in the coming years. But in 2026, for most nuclei familiari it is still not a replacement for a fixed batteria domestica. The reasons: higher costs, dependence on car availability, limited model compatibility and additional degradazione della batteria.
Our recommendation: invest now in a fixed batteria domestica for daily accumulo di energia. Once V2H chargers become cheaper and more cars support the technology, you can add V2H as a supplement. At Home Energy Solutions, we are happy to advise you on the optimal storage for your situation.
A fixed batteria domestica is available 24/7 and offers the most reliable storage. View our range.
