What is a blocking fee?
A blocking fee is a time-based component of a public EV charging tariff. It may apply when your car remains connected to a charge point for longer than a defined period.
The reason is straightforward: a charge point occupied by one vehicle is unavailable to the next driver. The extra fee encourages drivers to disconnect after charging and free the space.
Germany’s consumer advice network says many tariffs begin charging a per-minute blocking fee after a defined connection time, often after four hours. That is a common example, not a universal threshold.
Connection time is what often matters
Many tariffs do not look only at whether energy is currently flowing. They measure how long the vehicle remains connected to the charger.
Depending on the tariff, a blocking fee can therefore continue when:
- the battery is already full;
- the car has reduced its charging rate;
- the charging session has ended;
- the vehicle is still physically connected.
Always check the specific tariff. Some services use different rules or do not charge a blocking fee at all.
Do not confuse it with energy or parking charges
Several price components can apply during one public charging stop:
| Price component | What it covers | Typical format |
|---|---|---|
| Energy price | Electricity delivered | Currency per kWh |
| Time price | Charging or connection duration | Currency per minute or hour |
| Blocking fee | Extended occupation after an allowance | Currency per minute after a threshold |
| Start or session fee | Starting one charging session | Fixed amount per session |
| Parking charge | Use of the parking space | Separate parking tariff or meter |
A parking charge can apply independently of the charging tariff. Equally, free parking does not automatically mean there is no blocking fee.
When does the fee start?
There is no single answer. The individual tariff defines:
- the connection time after which the fee starts;
- the per-minute or hourly rate;
- whether the fee has a maximum cap;
- whether certain day or night hours are excluded;
- whether AC and DC charge points have different rules.
Germany’s Bundesnetzagentur explains that ad-hoc prices and additional price components must be known before charging begins. When you use an app or roaming service, the specific tariff shown for your session is still the one that matters.
A simple calculation example
Imagine a tariff that charges €0.10 for every additional minute after four hours of connection time. You disconnect after four hours and 35 minutes.
| Calculation | Amount |
|---|---|
| 35 additional minutes × €0.10 | €3.50 |
This is only an example. The actual threshold, minute rate, and maximum charge may be different.
Are AC and DC rules different?
They can be, depending on the service and station.
AC charging often takes longer, and some tariffs account for that with a longer allowance or a night-time exception. A shorter occupation may be expected at a rapid charger. Neither is a universal rule: always use the price displayed for the specific connector.
Does the blocking fee apply overnight?
Sometimes it does and sometimes it does not.
Some tariffs pause the charge during defined night hours. Others calculate it around the clock. A night-time exception may also depend on the tariff, operator, or charge-point type.
Do not rely on a general “free overnight” assumption. Check the displayed conditions before leaving the vehicle connected for a long period.
How to identify the fee before charging
Look for terms such as:
- blocking or occupancy fee;
- connection time;
- time price;
- parking;
- a price starting after a defined duration.
Check whether the fee begins immediately after the allowance and whether a maximum amount is stated. At charge points on managed parking sites, also check the local signs or parking tariff.
ChargEV FleX shows the available price components in the station and tariff details before charging begins. These can include the energy price, time-based costs, a blocking fee, or an operator session fee.
The current ChargEV FleX coverage and price analysis shows how many sites with an available ChargEV FleX tariff contain a time-based price. That figure includes charging-time and parking-time prices and is therefore not a count of blocking fees.
How to avoid unnecessary blocking costs
Read the tariff before starting
Do not check only the price per kilowatt-hour. Time-based components may matter more during a long stop.
Estimate the charging time
The charger’s maximum output is only part of the calculation. Your car, battery level, and charging curve also affect the session duration.
Monitor the session
Use the charging monitor and notifications in your chosen app. Leave enough time to return to the vehicle when charging is nearing completion.
Disconnect after charging
End the session correctly, unplug the cable, and release the charge point. Depending on the tariff, ending the session in the app may not be enough while the vehicle remains connected.
Frequently asked questions
Can the fee start while my car is still charging?
Yes. If the tariff is based on connection time, the fee can begin after the allowance even while energy is still flowing.
Does the fee stop when the battery is full?
Not automatically. With connection-based tariffs, the relevant time usually ends only when the vehicle is disconnected.
Does every public charger have a blocking fee?
No. Whether a fee applies and how it works depends on the specific tariff.
Can I also be charged for parking?
Yes. The car park and charging service can charge separately. Check both the tariff details and signs at the location.
Does ChargEV FleX show the fee upfront?
When a blocking fee is supplied for the selected tariff, ChargEV FleX displays it in the price details before you start.
In short
A blocking fee is not a standard surcharge. It is a tariff-specific time price for occupying a charge point beyond an allowed period.
Before charging, check the threshold, per-minute rate, possible cap, and night-time rules. Monitor the session and disconnect promptly.
