A motorway service area can minimise access time, while an off-motorway charging hub or Autohof may offer a better price or a more useful break. Neither is always better. Compare total stop time and total session cost, including the return to your route, before choosing a charger solely by its kWh price.

What are you actually comparing?

For this decision, distinguish a service area directly accessible from your carriageway from a stop reached through an exit. An Autohof is an off-motorway service location; nearby retail charging can be another option. The relevant difference is the actual route in and out, not the name on the map.

Check direction of travel. A charger on the opposite carriageway may be geographically close but require a substantial detour. Do not plan to use staff-only or service roads shown in map imagery.

Calculate the financial saving after the detour

A worked example

Suppose a fictional on-route charger costs €0.69/kWh and an off-route option costs €0.49/kWh. For 35 kWh, the gross saving is €7. A 10 km total detour at 20 kWh/100 km consumes about 2 kWh. Valued at €0.49/kWh, that is €0.98, leaving about €6.02 before parking, session fees and your time.

These are illustrative inputs, not prices for a particular operator. Use the tariff available through your actual payment method. An operator’s advertised direct rate may not be the rate on your charging card. Our existing charging-price guide covers that distinction.

Compare total minutes, not maximum kilowatts

Add driving, queueing, parking, authorisation, energy transfer and returning to the motorway. A charger rated higher may add little benefit if your car cannot use the extra power. An immediately available lower-rated point can sometimes win on total time.

Decide whether the break overlaps with something you would do anyway. A meal or supermarket visit can make a longer stop useful. But do not count a restaurant as available just because its building is visible: check its hours independently from the chargers.

Check the site’s practical details

Look at the number of compatible points, current status, toilets, shelter, lighting and access restrictions. If travelling with a trailer, verify bay layout and whether charging requires uncoupling; a standard car-space photo does not establish trailer access.

Confirm the price for your selected payment method and connector before you start. A familiar logo does not guarantee a free connector or a particular session cost. Include access time and the facilities you actually need when choosing between the two stops.

Make a primary stop and a fallback

Choose the preferred site while you still have enough range to use the alternative. Recheck availability before the last convenient exit. If a detour only saves a small amount but removes your backup margin, it is a poor trade.

StromNow supports planning for faster or more cost-efficient routes and useful charging stops. Apply that approach to the entire stop, then verify the station details. The nearby-charger checklist helps assess access, while choosing an 80 or 100 percent target helps avoid staying longer than the next leg requires.
