How does the invoicing of power consumed work?
In order to ensure that the power used by the electric car is charged to Daniel, an individual power meter is installed. This means that no costs will arise for the other tenants.
Is the charging of an electric car at a charging station safe?
- A charging station corresponds to a multiple-fuse “socket” which was developed especially for charging electric cars and fulfils all safety criteria.
- Unlike a normal socket, the charging station for electric cars has no live parts, provided no electric car is connected. Even if a wire or screwdriver comes into contact, nothing will happen.
- The sockets on the charging station are only suitable for electric cars and cannot be used to connect any other device.
- The electric car is monitored electronically during the entire charging process. In case of disruptions or warnings, the charging process is immediately terminated.
- Experts from TÜV Süd, DEKRA and the Allianz Zentrum für Technik confirm that electric cars are at least as safe as cars with combustion engines.
Although the charging of electric cars is safe, Daniel explains who will be liable in case of damage. In principle, the cause of the damage will decide who is liable:
- If the damage is caused by faulty installation, the certified electrician will be liable.
- If the damage is caused by the electric car of the charging station, the corresponding manufacturer will be liable.
- If Daniel fails to use the charging station correctly, he will be liable. For this, he checks his insurance policy in advance and makes sure that he is appropriately covered.
Advantage for owners of garages or parking spaces by installing charging station for electric cars
Daniel does not have to spend long explaining to his landlord that the installation of the charging station for an electric car will be of benefit not just for the parking space but the property as a whole. Electric mobility is becoming ever more accepted by the general public and politicians alike. Notable car manufacturers are significantly expanding their selection of electric models which will lead to an increased demand for charging stations in the future. Current and future tenants will demand this more and more frequently.
What happens to the charging station if Daniel moves out?
If Daniel moves out, the charging station can be fully uninstalled. The charging station can be removed by a certified electrician with ease and the cabling can also be removed if requested. However, it is significantly easier to cover the connections with a blind socket. In the approval agreement, Daniel has pointed out that, should he move out, the charging station must be removed but not the cables.
Ordering the charging station and technical inspection
Once the installation has been approved without issue, Daniel can concentrate on the charging station and its installation. Anna then informs Daniel that the installation of the charging station for the electric car may only be carried out by a qualified electrician. He therefore orders the appropriate charging station – the ABL charging station with 5 m cable and 22 kW capacity – and the corresponding installation service for his smart from The Mobility House’s online shop. Daniel receives a phone call from an electrician two days later and agrees an appointment with him.
One week later, the electrician comes by, checks the electrical set-up and explains to Daniel exactly which additional works are necessary. The charging station is connected to Daniel’s existing power supply/power meter in the basement of the block of flats. Since the charging power exceeds 12 kW, an Type A RCD EV with DC fault current detection is necessary, and in addition approval must be obtained from the network operator. Between the parking space and power meter there is a fire door, meaning breaking through the wall is subject to strict guidelines. Subsequently, 25 m of cabling is laid, wherein half the cable can be laid with “exposed wire” and half with existing cable racks. The electrician writes up a corresponding proposal (see table).

Daniel presents the proposal to the building administration once more and has the additional works approved by the property’s house electrician. Anna then gives the OK and Daniel calls the electrician to approve the proposal to install the charging station. The works are carried out two weeks later. After conclusion of the works, the electrician carries out tests on the charging station for the smart electric drive, records the measurement values and instructs Daniel on how to operate the charging station.
The charging station is installed and Daniel is thrilled. His neighbours have even asked him about his experiences and want to follow his example. One has already submitted an application for a charging station for his parking space to the building administration.
