EV charging in apartment buildings
How many stations does an apartment building need and how do you split the costs? We design a solution with load management, metering and RFID access. Installation is carried out by a certified IONT partner.
What the building regulations require
The number of EVs among flat owners is growing. Since November 2021 an amendment to the Czech building regulation (No. 266/2021 Coll.) requires buildings to be prepared for charging.
Apartment buildings
New and renovated apartment buildings with more than 10 parking spaces must have cabling (ducting) prepared at every space for the later installation of charging stations. Plan for this when designing the electrical installation. Stations can then be added gradually and add value to the flats.
Other new buildings
New non-residential buildings and alterations with more than 10 parking spaces must have at least one charging station and ducting for every fifth space. The obligations of existing non-residential buildings are described on our business charging page.
How to choose a charging station?
The regulation does not set the station power. Typical residential stations have 3.6–22 kW, and even lower power charges most cars overnight. A high-power station charges quickly but stands idle most of the time.
That is why we recommend dynamic load management. It regulates station consumption so that the limits of the electrical installation and the reserved capacity are never exceeded. When needed, some stations can charge fast while total demand stays low.
In buildings with load management the main circuit breaker must also be sized correctly. The recommended values depend on the number of parking spaces, and we are happy to calculate them with you.
How to meter consumption?
Separate supply point
Each station has its own meter and contract with the distributor. The simplest cost split, but higher connection costs.
Shared metering
All stations share one supply and have sub-meters that belong to the owners of the parking spaces.
IONT info app
Monitor consumption and manage charging in the IONT info app:
- consumption statistics
- remote authorisation
- RFID and user management
- charging start timer
Stations for apartment buildings
For overnight charging in garages and at spaces next to the building.
e:car WALL PRO
Wallbox with display and metering for shared garages and residential developments.
What we provide
Installation by certified partners
Installation, commissioning and inspection are carried out by a certified IONT partner in line with regulations and standards. How installation works.
Secure access
An RFID card or PIN ensures that only authorised users can use the station.
Cost allocation
In the IONT info app you track energy consumption and charging costs for every user.
Fire safety and NZÚ
Fire safety in garages
Owners of spaces in shared garages often ask what charging must comply with. The requirements are set by the building’s fire safety design. A useful guide is the methodological recommendation of the Czech Fire Rescue Service on parking and charging EVs in buildings.
New Green Savings 2026+
Apartment buildings can finance charging stations with an interest-free loan from the New Green Savings (NZÚ) programme; the stations are an eligible cost. NZÚ conditions for apartment buildings.
Charging in residential projects

Frequently asked questions
How many charging stations does an apartment building need?
It depends on the number of spaces and residents’ interest. New and renovated buildings with more than 10 spaces must have cabling prepared at every space; stations can then be added gradually as needed.
How do we split electricity costs between flat owners?
Either with a separate supply point for each station or with shared metering and sub-meters. The IONT info app also shows each user’s consumption.
Why is load management needed?
Dynamic load management ensures the stations never exceed the capacity of the electrical installation and the building’s reserved power. It also allows a smaller main breaker.
Can apartment building stations be subsidised?
Yes. New Green Savings 2026+ offers apartment buildings an interest-free loan, and charging stations are an eligible cost.
Who installs the station?
IONT tech develops and manufactures the stations. Installation, commissioning and inspection are carried out by certified IONT installation partners across the Czech Republic. After your enquiry we will put you in touch with a suitable partner.
