Germany — EV charging and AC up to 22 kW
A very large market and regulation that creates clear need for energy management.
The 1–5 score is HUBCORE's operational estimate of how smoothly an AC solution of up to 22 kW can be prepared and delivered in practice. It is not an official country rating or an assessment of the quality of national regulation.
In 60 seconds
In Germany a wallbox must be notified to the grid operator before commissioning.
A wallbox above 12 kVA (~11 kW) requires grid operator consent; the operator must respond within 2 months and, if refusing, give reasons and describe possible remedies.
From 1 January 2024, new private controllable consumption devices, including private wallboxes above 4.2 kW, must participate in the §14a EnWG controllability framework.
This means a controllable, measurable solution is not an added extra but a precondition.
AC up to 22 kW: what must be checked?
Existing grid connection capacity
Check the building's connection capacity and planned charging power; the 11 kW threshold is an important milestone here.
Capacity upgrade
Above 12 kVA (~11 kW), grid operator consent is required; allow for the response period of up to 2 months.
Apartment building decision
In an apartment building, an owners' decision and a clear metering and billing model are needed.
Public or private use
Public charging points are not covered by that specific §14a private-consumer rule, but the AFIR framework applies to them.
Installer requirements
Installation and notification go through a competent local electrical contractor; DSO processes differ.
Detached house
For a detached house the wallbox must be notified and, above 12 kVA (~11 kW), consented. Under §14a EnWG, from 1 January 2024 new private controllable devices, including wallboxes above 4.2 kW, must participate in the controllability framework; during grid congestion consumption may be temporarily reduced to at least 4.2 kW, in exchange for a grid fee reduction.
Apartment building
In an apartment building the key question is how several wallboxes fit within the shared connection and how they are controlled. Each point requires notification and, above 11 kW, consent.
Commercial property
In commercial property, AC up to 22 kW fits employee parking well. At higher power, grid operator coordination and energy management matter more than hardware choice.
Public charging
Public charging points are not covered by the §14a private-consumer rule. For public charging follow AFIR: ad hoc charging, electronic payment at newer points and a clear price before the session.
Advantages
- A very large market and long-term demand.
- Regulation creates clear need for energy management, controllability and integration.
- Under §14a, controllability is linked to a grid fee reduction, giving the customer a tangible benefit.
Drawbacks and risks
- Above 11 kW, grid operator consent is required, adding to the timeline.
- §14a controllability requirements demand technically correct implementation.
- Many local distribution operators with differing processes.
What HUBCORE solves here
- Dynamic load management that keeps charging within permitted limits.
- Measurement and monitoring of energy flows so control decisions are evidenced.
- Coordinated control of multiple chargers behind a shared connection.
- Reporting and integration readiness with the building energy system.
We keep track of markets and technology and guide the customer to a suitable solution. A solution must be measurable, controllable and integrable.
Check before quoting
- Planned charging power and whether it exceeds the 11 kW threshold.
- The local grid operator's notification and consent procedure.
- Applicability of §14a controllability requirements.
- Connection capacity and measured peak load.
- Metering and billing model.
