Installation service for charging stations

Real use cases

Depending on the circumstances on site - whether in a single-family home, a multi-party apartment with underground parking or in a semi-detached house - the costs for installing a wallbox vary greatly.

We can show you, using real examples, which additional costs can be incurred when installing a charging station, regardless of the environmental situation.

Single family home with garage

Thomas charges his Tesla Model S at home

Ordering a KEBA charging station and installation check from The Mobility House

Thomas lives with his family in a detached house with its own garage. In one month, his brand-new Tesla Model S with double charger is arriving. In The Mobility House’s online shop, Thomas has already found a KEBA charging station with a 4 m cable and 22 kW charging power (price: € 999.00). He also orders the installation check (price: € 199.00) in order to have his electrical set-up assessed and the charging station for his Tesla installed. Two days later, an appointment has already been agreed and two weeks later a qualified electrician comes to Thomas’ house.

Checking the electrical installation in the garage

Previously, only a power supply for lighting and two domestic sockets in Thomas’ garage were available. This is not enough to charge the Tesla quickly. For the 22 kW connection of the KEBA charging station, 18 m of cabling from the fuse box in the house to the garage had to be installed. Here, it was necessary to break through a wall. In addition, the electrician must install those safety features required by the standards, and obtain permission from the network operator since the home charging station exceeds a load capacity of 12 kW. Firstly, the electrician provides Thomas with a detailed proposal for the additional services described (see proposal table). Thomas then confirms that he wishes the installation to be carried out in this manner. Due to the necessary additional works, the installation has to be performed at a second appointment.

Installation of the wallbox with instruction

The installation is carried out without any hitches. At the end, everything has been installed and all traces of a handyman ever being there have of course been removed. The electrician then turns on the charging station for the Tesla and tests the functions and checks the measurement values. Finally, he shows Thomas how to charge his Model S with the new charging station.

Apartment with underground parking

Daniel loads a smart EQ

Requesting the installation of a charging station via the property management company

The parking space and the walls of the garage are deemed communal property. Therefore, Daniel needed the approval of the community of owners before making constructional changes. In order to agree the installation with the community of owners, he first contacted the building administrator by e-mail and requested more information on the approval process. Anna from the house administration places his application on the agenda of the next community of owners meeting where the installation of the charging station will be voted on. She also asks Daniel to attend the community of owners meeting in case of questions. Daniel speaks with certain tenants in advance who are also owners in order to gather a few questions. Now Daniel knows the thoughts of his fellow tenants with regards to charging power costs and the safety of electric cars and can prepare himself as best possible for the community of owners meeting.

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).

Installation of the wallbox in the underground garage

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.

Semi-detached house with garage

Franz and the Renault ZOE

Advice from The Mobility House about a KEBA charging station and the installation check

Franz lives in a semi-detached house in Garching, Munich with his wife. In future, he would like to drive to work in an electric car and orders a Renault Zoe. This is to be parked and charged in the built-in garage. Franz read some information about charging his ZOE at home on the internet and decided to seek the advice of The Mobility House. He calls the Service Center and is forwarded to Michael, one of TMH’s experts. Franz briefly outlines his situation. At the time the house was built, he had already been thinking that in future he might drive an electric car and would like to equip his garage with a 22 kW industrial socket. After a few minutes, Franz knows exactly what he needs. When choosing the right charging station for his Renault ZOE, Franz must ensure that this is ZE READY certified. Three days later Franz orders a KEBA charging station with 22 kW capacity and socket. He would like to be able to connect various electric cars flexibly and also to offer his electric car-loving friends the opportunity to charge their cars at his house. The Renault ZOE has a type 2 socket. If Thomas’ friend Peter comes by with his Nissan Leaf, he will need a power cable with a type 1 connection. Even though Peter’s Nissan Leaf can only charge with 3.3 kW, he can still connect this to the 22 kW charging station. In order to have the charging station correctly installed, Franz orders the installation check. The day after next, he is called by a qualified electrician who agrees an appointment with him.

Checking the electrical installation in advance

The cable already laid can be used by the electrician without issue. The red CCE socket is simply replaced by the KEBA charging station (22 kW) for the Renault ZOE and an RCD type A with DC fault current detection must simply be installed. Thanks be to bureaucracy – the electrician compiles a short proposal for the RCD (see proposal table).

Mounting the wallbox on the garage

The installation of the charging station including installation of the RCD type A with DC fault current detection is complete after just 2 hours. Franz is then instructed on how to operate his new KEBA charging station. Now he can scarcely wait until his Renault ZOE is delivered in the next few days and he can rely solely on electricity on his way to work. He now has a proper power supply for his new car.
