Sockets for our new (e-)cars.

In the first case, solutions quite literally have to be created on the “green field”. And not every field (or every rest area) has a power cable suitable for this purpose. Yet even in a city, the solution is not so simple. The answer here is a “wallbox”, as the modern “sockets” for e-cars in an underground car park, for example, are called. One wallbox in an underground car park is usually not a problem. But 30, 40 or even 100 of them in one place (for example in a city district, since many people now want to be electrically mobile) is. This is because if all the car owners were to want to charge at the same time, this would regularly blow even the strongest fuse. That is, if the responsible electricity supplier has enough “thick cables” there to be able to handle the amount of electricity in the first place. Intelligent “load management” soon becomes the magic word, along with the question as to whether all the available wallboxes will ultimately get enough power to ensure that all the vehicles are really sufficiently charged again within the advertised “20 minutes”. The situation is further complicated by the fact that wiring harnesses in buildings are not necessarily designed for continuous operation with high amounts of electricity, meaning that there is also a heat-related risk of fire and this must be factored into the planning. It is not unusual for excavators and hammer drills to be needed in order to install more powerful cables and distributors before a wallbox can even be connected.
