Information as of 11 Oct 2026. Based on the published tariffs of EnBW mobility+ (tariff status 1 Dec 2025) and Ionity (price change of February 2026) plus an ADAC spot check on ad-hoc charging. Charging prices change regularly – check the provider's app before every trip.

At home you have one electricity tariff and one bill. On the road it gets more complicated: at the very same fast charger, three drivers can pay three different prices for the same kilowatt-hour – depending on whether they pay spontaneously with a bank card, use a charging card without a monthly fee, or have a subscription. So the real question isn't "Which provider is cheapest?" but "Which way of paying fits how I drive?".

This article explains the three ways to pay, works through two large German networks – EnBW and Ionity – to show when a monthly fee pays off, and shows how to calculate your own break-even point in two minutes. For a broader comparison including Shell, Maingau, ADAC, EWE Go and Plugsurfing, see our charging card comparison 2026.

Three ways to pay on the road

1. Ad-hoc charging: You pull up, tap your bank or credit card on the terminal (or scan a QR code) and charge – no contract, no registration. Convenient for occasional use, but usually the most expensive option.

2. Charging card or app without a monthly fee: You register once with a provider (mobility service provider) and pay a fixed contract price per kilowatt-hour. No monthly cost, but the price is usually higher than with a subscription.

3. Subscription with a monthly fee: You pay a fixed monthly or annual fee and get a lower price per kilowatt-hour in return – often only at the provider's own stations. It only pays off above a certain monthly charging volume.

Many drivers combine these. A subscription for the network you use most, a no-fee card for everything else and ad-hoc as a fallback is often the cheapest setup in practice.

Ad-hoc charging: convenient, but with a surcharge

Since 13 April 2024, the EU regulation AFIR requires newly built public DC fast chargers of 50 kW and above to accept ad-hoc payment by card or contactless and to bill per kilowatt-hour. Existing fast chargers must be retrofitted by 2027. Our article on AFIR card payment at chargers covers the details.

The obligation to offer ad-hoc payment says nothing about the price, though. An ADAC spot check at motorway fast chargers found that spontaneous charging can cost up to 62 percent more than a contract tariff without a monthly fee. One example from the sample: at EWE Go a kilowatt-hour cost 84 cents ad hoc and 52 cents with a contract. Ionity also offers two ad-hoc options in Germany: "Ionity Direct" without any registration at €0.69/kWh and "Ionity Go" with free registration in the app at €0.66/kWh (prices since February 2026).

Rule of thumb: ad-hoc is a good fallback, but if you charge publicly more than once or twice a month you should at least have a charging card without a monthly fee.

Example EnBW mobility+: three tariffs, one bill

EnBW runs one of Germany's largest fast-charging networks and offers three tariffs. According to EnBW (tariff status 1 Dec 2025), the following prices apply at EnBW stations, the same for AC and DC:

Three details matter. First, the lower subscription prices only apply at EnBW's own stations. At other operators' charge points in the EnBW network, all three tariffs pay the same variable price of 56 to 89 cents per kilowatt-hour, according to EnBW – so the subscription brings no benefit there. Second, an idle fee of 10 cents per minute applies after more than four hours plugged in, capped at €12 per session. Third, EnBW energy customers get a 10 percent discount at EnBW stations in the "Vorteils" tariffs.

EnBW itself gives these guide values: tariff S up to about 60 kWh per month, tariff M from 60 kWh, tariff L from 86 kWh – each based on charging at EnBW stations. You can reproduce these numbers with a simple calculation (see below).

Example Ionity: long distance with or without a subscription?

Ionity operates high-power chargers mainly along motorways. Since the price change in February 2026, the following applies in Germany:

According to Ionity, the ad-hoc prices apply only at German stations; conditions in other countries may differ. The annual plans are slightly cheaper than twelve monthly fees but tie you in for a full year – mainly worthwhile for drivers who do long trips throughout the year.

Break-even: when a monthly fee pays off

The maths is simpler than the tariff jungle suggests. A subscription pays off as soon as the saving per kilowatt-hour covers the monthly fee:

Break-even (kWh per month) = monthly fee ÷ price difference per kWh

Applied to the prices above:

The EnBW figures match the guide values EnBW publishes. For context: a typical fast-charging stop on a long trip often adds 30 to 50 kWh, depending on battery size and state of charge. At Ionity, the Power plan can therefore pay off with a single larger stop per month – provided you actually charge at Ionity.

What it costs per month: three driving profiles

The table shows monthly costs if the whole amount is charged at the respective network's own stations (fee plus energy, rounded):

At 40 kWh a month – roughly two smaller stops – the no-fee tariff is cheapest or only slightly behind on both networks. At 100 kWh the subscriptions are ahead, and at 200 kWh the most expensive plan saves around €22 a month at EnBW and around €42 at Ionity compared with the no-fee tariff. If you charge on the road less than once a week, think twice before paying a monthly fee.

The most common misconceptions

"With a subscription I charge cheaper everywhere." Usually not. Subscription prices typically apply only within the provider's own network. At third-party stations you often pay the same roaming price as without a subscription – at EnBW around 56 to 89 cents per kilowatt-hour, regardless of tariff.

"One busy month justifies the annual plan." What counts is the average over the year. If you drive long distances in summer and charge at home otherwise, a monthly plan for the travel months is often the better choice. Notice periods and minimum terms are in the provider's conditions – check them before signing up.

"The price at the charger is the price." The per-kWh price is only part of it. Idle fees can make a session noticeably more expensive if you stay plugged in too long – at EnBW after four hours. At fast chargers, some providers start charging idle fees much earlier.

"Ad-hoc costs the same everywhere." The differences are large. Even at Ionity, Direct and Go differ by 3 cents per kilowatt-hour – just for a free registration.

How to find the right price on the road

Theory doesn't help much when you're at a motorway exit with 15 percent battery left. In practice, three steps work:

1. Know your profile: How many kilowatt-hours do you charge publicly per month, and on which network? A look at your charging history for the last three months is enough.

2. A no-fee card as your base: It covers most third-party stations. Which cards exist and what they cost is in the charging card comparison; how roaming works is explained in EV charging roaming explained.

3. A subscription only for the network you really use regularly: And only if your monthly volume is above the break-even point.

In Elunio you can filter charging stations by price and see prices other drivers actually reported at a station – not just the official list price. The "My charging card applies" filter hides stations where none of your marked cards is recommended. Why reported prices are often more telling than list prices is explained in Community prices vs. list prices.

Frequently asked questions

What is the difference between ad-hoc charging and a charging card?
With ad-hoc charging you pay spontaneously without a contract, for example by bank card at the terminal. With a charging card or app you have a contract with a provider and pay its contract price. Ad-hoc is usually more expensive but needs no registration.

From how many kilowatt-hours does a charging subscription pay off?
Divide the monthly fee by the saving per kilowatt-hour. At EnBW, tariff M beats S from about 60 kWh a month; at Ionity, the Power plan beats the Go tariff from about 44 kWh – in each case only for charging at the network's own stations.

Does the subscription price also apply at other operators' stations?
Usually not. At EnBW, all three tariffs pay the same variable price of 56 to 89 cents per kilowatt-hour at third-party stations. The provider's app shows the current price before you start.

Does every charger have to accept card payment?
Newly built DC fast chargers of 50 kW and above must offer ad-hoc payment by card or contactless since 13 April 2024; existing ones by 2027. Different rules apply to slower charge points.

Is an annual Ionity plan worth it?
Power 365 costs €119.99 a year instead of 12 × €11.99 = €143.88 when paid monthly. It pays off if you charge at Ionity regularly all year round. If you only drive a lot in a few months, the monthly plan is more flexible.

Conclusion

There is no single cheapest tariff for charging on the road. For occasional chargers, a card without a monthly fee is almost always better than spontaneous ad-hoc charging. A subscription only pays off above a certain monthly volume – around 60 kWh at EnBW, already from about 35 to 45 kWh at Ionity – and only within the provider's own network. If you know your charging volume and work out the break-even once, you'll pay noticeably less on the road.
