V2H and V2G sound like the future of charging. A sober look at what actually works, what can be bought in Switzerland in 2026 and what is still marketing.
Normal charging only flows in one direction: power from the grid or the solar system into the car. Bidirectional charging reverses this: the car can also discharge its battery again, either into your own house (V2H, Vehicle-to-Home, mostly to bridge a power cut or to use solar power you generated in the morning in the evening) or back into the public grid (V2G, Vehicle-to-Grid, for which the grid operator even pays in some countries). The car thus becomes a large, mobile energy store.
The clear answer: practically only the VW Group, and even there only with the right software version. The following are currently ready for series production as bidirectional (DC, via CCS):
For Hyundai/Kia (E-GMP platform), part of the specialist press also promises genuine V2H, but the manufacturers themselves only talk about V2L (power for devices via a socket on the car, no house connection) and describe V2H/V2G as "in development". On this page we therefore only list what manufacturers themselves confirm as available.
An older vehicle generation with a CHAdeMO connector (Nissan Leaf, Honda e, Mitsubishi Outlander PHEV, Citroën C-Zero, Peugeot iOn) also supports bidirectional charging, but via a completely different device category from the VW platform above.
This is the part that most articles skim over: "bidirectional" does not mean equally expensive.
Affordable: AC bidirectional. The Zaptec Go 2 already supports V2G over a normal Type 2 AC connection (no additional DC converter needed), rolled out in Switzerland since 2025. Publicly listed hardware price: from CHF 889.–, so in the range of a normal wallbox. It is unclear whether activating V2G itself requires another surcharge or a subscription, which you need to ask the dealer.
Expensive: DC bidirectional. For genuine V2H with meaningful output you need specialised DC wallboxes that come with their own inverter. The EVTEC device "crema&charge Bidi" (22 kW, for the VW MEB platform) is sold in Switzerland, e.g. via sun2wheel, as the "Two-way-20" for around CHF 13,000.–, in some cases with cantonal subsidies (e.g. CHF 2,000.– each in the cantons of Zurich or Lucerne). Other providers such as the EDISON V2H (E3/DC, Hager Group) or ambiCHARGE (Ambibox) give no public Swiss price, only "on request".
The reason for the price difference: DC devices handle the AC/DC conversion themselves and can usually be combined directly with a home battery/PV system, which requires considerably more hardware than a pure AC wallbox with V2G software.
Honestly: for most households, not yet, at least not solely because of bidirectionality. The large DC devices cost more than a complete solar battery of comparable capacity, and real payment for feeding back into the grid (V2G) is not yet an established, nationwide business model in Switzerland. It makes most sense if you already have a PV system and want to use the car as a buffer for self-consumption (V2H), or if backup power during a power cut is of concrete interest to you.
The affordable AC variant (Zaptec Go 2), on the other hand, costs hardly more than a normal wallbox and is worthwhile more as "prepared for later", in case suitable payment models become established, provided your vehicle supports it at all.

As of: September 2026. Vehicle compatibility and prices change quickly in this market segment, and we update this page regularly, but it is always worth asking the manufacturer before buying.
