The installation of the connections for charging e-vehicles is a task for your electrician.

In principle, all specialist companies entered in our list of installers are authorized to connect the charging infrastructure. Further information can be found on the website of the Central Association of German Electrical and Information Technology Crafts (ZVEH). There you will find, for example, a technical guide with numerous information on the details of a charging infrastructure. You can also use this website to search for installers.
