Bidirectional Charging in 2026: V2H, V2G and What Is Really Changing in Germany
📅 Published October 14, 2026
Information as of 14 Oct 2026. Based on reports from electrive.net, basicthinking.de, ema-energiewelt.de and evinfrastructurenews.com, plus manufacturer claims as reported there (sources at the end). The topic moves fast; terms and rules can change. Where sources disagree or something is still open, the text says so. This is not legal or tax advice.
In early October 2026 Germany's Federal Network Agency (Bundesnetzagentur, BNetzA) published its final MiSpeL decision – the rule that determines how electricity an EV takes from the grid, stores and later gives back is treated. At the same time, the first consumer offers have appeared in which the car feeds power back into the grid in return for money or a discount. Time for a sober stocktake: what do V2H, V2G and V2L mean, what has changed legally, which offers exist with which numbers, and what is still unresolved?
This article is deliberately not a sales pitch for bidirectional charging. It should help you judge whether the topic is already relevant for you – or whether you are better off waiting.
The terms: V2L, V2H, V2G, V2B
"Bidirectional charging" covers several operating modes that differ a lot technically and legally. Following basicthinking.de:
V2L (Vehicle-to-Load): the car acts as a power bank for individual devices, such as tools or camping gear. No grid draw, no grid operator, no billing.
V2H (Vehicle-to-Home): the car supplies the home network for self-consumption. Nothing flows into the public grid; according to basic-solar.de no grid operator, authorities or billing are involved.
V2G (Vehicle-to-Grid): the car feeds electricity back into the public grid. This is the most regulation-heavy variant: you need an electricity contract that pays for feed-in, a smart metering system, registration with the grid operator and – during the transition phase – its consent.
V2B (Vehicle-to-Building): supplying commercial buildings, often with several vehicles.
Most current consumer offers are V2G offers in which an energy supplier controls charging and discharging. If you only want to raise self-consumption of your own solar system, V2H may be the legally simpler case. For wallbox basics see the home wallbox guide, for solar power the article on charging with solar surplus.
What has changed legally
EVs as storage. In late 2025 the Bundestag passed an amendment to the Energy Industry Act (EnWG) under which electric cars are legally treated like stationary battery storage. The double grid fees on storing and feeding back are meant to fall away as a result. The sources give different months for the vote (basicthinking: September 2025; the Ford report on electrive and ema-energiewelt: November 2025); they agree that the change applies from the start of 2026.
MiSpeL (market integration of storage and charge points). BNetzA issued its final decision in early October 2026. It determines which metered quantities at a charge point count as consumption and which as temporarily stored power fed back – also with regard to levy exemptions under the Energy Financing Act and the EEG market premium. According to electrive.net the rules apply to public and non-public charge points. The grid-fee side is handled by the reform AgNes; the electrive report gives no euro amounts for it.
An important last-minute change followed industry criticism (electrive.net, 1 Oct 2026): the first draft from early August required a second meter for the "separation option" (separate metering). Owners without a solar system can now use this option with a single smart metering system. For the "flat-rate option" for solar owners, which uses the existing grid-connection meter, the buffer zone was reduced from factor 0.5 to 0.2 so that feeding back grid power pays off sooner; according to the report the first 500 kWh fed into the grid keep EEG support under that option. In September, BMW, Ford, Elli, E.ON, Octopus Energy, The Mobility House and Enpal had criticised the draft in an open letter for "considerable technical, economic and operational hurdles". BNetzA said stricter hurdles were meant to prevent abuse, such as registering charge points without owning an EV.
Transition phase. According to basicthinking.de and ema-energiewelt.de, practical implementation needs the consent of the grid and metering operator until the end of September 2027. The head of the service provider Lumenaza doubts, per basicthinking, that broad implementation will happen before October 2027. electrive gives no date for the MiSpeL decision taking effect; ema-energiewelt lists 21 October 2026 as the expected date, which we could not confirm with a second source. Do not treat that date as certain.
No legal entitlement to payment. ema-energiewelt explicitly points out that there is no statutory right to a feed-in payment. What you receive depends solely on the contract with your provider.
The first offers – with numbers
BMW iX3 with E.ON
In September 2025 BMW and E.ON presented what they describe as the first commercial V2G offer for private customers in Germany. According to evinfrastructurenews.com it was available to customers by 16 February 2026. Key data:
Vehicle: models on the "Neue Klasse" platform with sixth-generation eDrive; the first is the BMW iX3 (from €68,900 per electrive).
Wallbox: the BMW Wallbox Professional (DC, up to 11 kW) is required, listed at €2,094.40 in BMW's configurator at the time of the report. The AC "Plus" wallbox (€699) is not suitable for bidirectional charging. According to evinfrastructurenews the first 100 customers who choose the E.ON V2G tariff get a €700 wallbox discount.
Contract: E.ON ÖkoStrom Home & Drive V2G combined with the "V2G Plus" feed-in contract; a smart metering system is required. Fixed energy price per kWh and a fixed base fee.
Remuneration: a plug-in bonus of 24 cents per hour the car is connected, capped at €60 per month or €720 per year (about 250 hours a month), plus 40 cents per kWh fed back (evinfrastructurenews; the September 2025 electrive report did not yet state the amount).
BMW's own example (electrive): at an average energy price of 32.97 ct/kWh the bonus covers up to 2,184 kWh per year – which BMW says is enough for roughly 12,000 to 14,000 km of annual driving (WLTP) in the iX3 50 xDrive. You can check it: 2,184 kWh × €0.3297/kWh ≈ €720. Note that this is the manufacturer's framing under favourable assumptions, not a guaranteed gain.
Ford Capri/Explorer with Octopus Energy and Ambibox
In February 2026 Ford announced a V2G offer for private customers (electrive.net): tariff from Octopus Energy, bidirectional DC wallbox from Ambibox, start in Germany in summer 2026. Supported are the Ford Capri and Explorer from model year 2026; for older vehicles with 77 or 79 kWh batteries Ford does not specify the capability and advises asking the customer centre.
Bonus: €30 per month if the car is connected at least 300 hours a month (up to €360 a year).
Discount: 18 ct/kWh off the household electricity price for up to 2,400 kWh per year. Assuming a household price of 33 ct/kWh, Ford calculates an effective average of about 15 ct/kWh; per Ford the 2,400 kWh are enough for up to 16,000 km at 15 kWh/100 km (real-world range lower).
Control: Octopus controls charging and discharging automatically. You set departure time and target charge level and can switch off V2G optimisation to charge at up to 11 kW.
An example calculation from the stated figures (not from Ford): if you use the full discount, you save 2,400 kWh × €0.18 = €432 per year; together with the maximum bonus of €360 that is at most €792 of benefit per year – provided you reach 300 hours a month and actually consume the 2,400 kWh at that discount. Wallbox costs are not included; the report gives no reliable price.
Other providers
According to ema-energiewelt, an offer from VW/Elli with a bonus of up to €720 in the first contract year was announced in June 2026; the report gives no start date. We have not checked this against a second source and list it for orientation only.
What bidirectional charging costs – and what is unclear
Hardware. According to basicthinking.de, bidirectional wallboxes cost between €2,000 and €4,000. BMW's wallbox at €2,094.40 is at the low end. A rough calculation using only the numbers above: with the full BMW bonus of €720 a year, a €2,094.40 wallbox would be "paid off" after about 2.9 years, with the €700 discount (€1,394.40) after about 1.9 years. This is a rough upper bound of the benefit: it ignores that the special tariff may be more or less expensive than your current one, feed-in payments, installation costs and wear.
Smart meter. You need a smart metering system. According to ema-energiewelt only 5.5% of metering points were equipped at the end of 2025. When your metering operator equips you is therefore a real hurdle.
Vehicle. basic-solar.de points out that the hardware in many cars is technically capable, but most manufacturers have not yet enabled discharging in software. Older models sometimes refuse reverse power flow, according to basicthinking.
Battery and warranty. BMW says the additional discharge cycles do not impair battery life thanks to protective functions; basicthinking refers to a study according to which bidirectional charging hardly harms batteries. At the same time, basicthinking says it is unclear whether manufacturers generally cover battery damage caused by bidirectional charging. A typical warranty is around eight years or 160,000 km, based on normal driving and charging. Check your vehicle's warranty terms in writing.
Losses. Charging and discharging both involve losses, as we showed for the charging side in our article on EV charging losses. The sources we checked give no reliable efficiency figures for the return path, so we do not quote any.
Economics. basicthinking.de cites an Agora forecast of around €500 per year by 2030 – well below the bonus values in today's offers. The article's conclusion: the rule change is progress, but it does not automatically turn an EV into a profitable business model.
Who is it worth it for already – and who should wait?
Some rules of thumb can be derived from the sources (conclusions, not guarantees):
More interesting: you drive or plan a model that supports a V2G offer (currently BMW iX3, Ford Capri/Explorer), have a fixed parking spot where a wallbox is possible, keep the car plugged in for long periods (the bonuses depend on connection time), and already have or will get a smart metering system. Combined with a solar system the storage can, per basicthinking, charge at midday and feed the house or the grid in the evening.
Better to wait: you have an older model without a manufacturer release, park irregularly or on the street (without your own spot see EV charging without a driveway), or you need a full battery every morning for long trips. Anyone unsure about the cost-benefit calculation should not invest in a €2,000–4,000 wallbox before contract, warranty and grid-operator consent are clarified.
A checklist before buying: (1) Has the manufacturer released discharging for exactly your model and model year? (2) What does the contract say – energy price, base fee, term, cancellation? (3) When will you get a smart metering system? (4) Does the grid operator consent (transition phase until 30 Sep 2027)? (5) What does the battery warranty explicitly say about bidirectional use? (6) What target charge level do you need every day?

How Elunio fits in – and where the limits are
Elunio does not support bidirectional charging and does not control wallboxes. The app helps on the road: charging stations on map and list, filters by power, price and connector type, and prices that other drivers have actually reported at a station. Even if you charge bidirectionally at home, on long trips you still depend on public fast chargers. Data coverage varies by region: the best live coverage is in Baden-Württemberg (live occupancy via MobiData BW) and the DACH region; elsewhere status is based on community reports and is not complete. Why reported prices are often more meaningful than list prices is explained in community prices vs. list prices.
Frequently asked questions
What is the difference between V2H and V2G?
V2H supplies your house from the car battery; V2G feeds power back into the public grid and needs a contract, a metering system and the grid operator's consent.
Is there a legal right to payment?
No. ema-energiewelt explicitly notes there is no statutory entitlement; remuneration comes from the contract.
What does a bidirectional wallbox cost?
According to basicthinking.de €2,000 to €4,000; the BMW Wallbox Professional was listed at €2,094.40 in the configurator.
Which cars support consumer V2G offers?
According to the sources checked here, currently the BMW iX3 (E.ON) and Ford Capri and Explorer from model year 2026 (Octopus). More manufacturers are announcing offers; check the release for your model.
When do the new MiSpeL rules apply?
BNetzA issued the decision in early October 2026. electrive gives no date for it taking effect; until the end of September 2027 implementation needs the consent of grid and metering operators.
Conclusion
In 2026 bidirectional charging has moved from pilot project to contract product, but it is not yet a sure thing: the legal situation has improved and the numbers of the first offers sound attractive, but hardware costs, smart-meter availability, grid-operator consent until autumn 2027 and open warranty questions remain real hurdles. Calculate with your own values – parking time, electricity tariff, wallbox price – and do not rely on providers' maximum amounts.
