Mobile or permanently installed: Which wallbox is right for you?

Those who want to be able to charge their electric car or plug-in hybrid at home face a decision: To buy either a mobile charging station or a permanently installed wallbox? Before deciding on one of the two options, you should ask yourself the following three questions in order to make the right choice.

What is my charging behaviour?
If I am on the road a lot and can charge at a private power socket during appointments or overnight - e.g. at companies, hotels or at my secondary residence - the mobile wallbox is a practical solution. Various adapters also expand the range of uses to include plug formats from other countries. If, on the other hand, the electric car is primarily charged in one's own garage or carport, the permanently mounted wallbox is the perfect charging solution.

No other charging option is as practical, convenient and safe: simply open the cover and plug in. The charging cable is usually permanently attached, making it theft-proof and always at hand. Unlike a mobile charger, it does not have to be retrieved from the boot before each charging session or be left lying on the floor of the garage where it gets dirty, which can lead to charging interruptions.

Which charging method suits my living situation?
If you often need to charge your electric car at different locations with electricity from different sockets, a mobile charger is a good choice. Unlike the permanently installed wallbox, which has to be registered in Germany, for example, the mobile version - if the power socket is already available - simply means: plug in & charge.

Here, however, the scope of services is mostly limited to basic functions. For e-car drivers with their own home, in particular, this is insufficient. They want a solution with which the car can also be charged using self-generated solar power in order to make optimal use of an energy surplus. To date, the integration of the home's own photovoltaic system only works with permanently installed wallboxes. Such a charging solution can also be integrated into the smart home, which optimises the entire energy management of the house.

What do I use the e-car or the plug-in hybrid for?
If the electric vehicle is used for purely private purposes, it is of little importance who charged how much electricity for which distance. However, this is important if a distinction has to be made between private and professional use or if several drivers share a wallbox.

Only permanently installed wallboxes, such as the P30 c- and x-series from KEBA, offer the possibility to invoice the kilowatt hours charged at home to the employer or leasing company thanks to the fully integrated MID-certified meter, or can allocate charging sessions to different people via RFID. This is not possible with mobile wallboxes. For those who do not see price as a deciding factor: mobile wallboxes are not fundamentally cheaper or more expensive than permanently installed ones. Rather, price differences result from different functionalities.
