Charging systems for electric cars and plug-in hybrids

Product Report | 04.10.2022

With the new 11 kW wall boxes, Spelsberg presents charging systems for electric cars and plug-in hybrids. With the Pure and Smart Pro models, there are two different versions.


The new wall box from Spelsberg enables safe and convenient charging at home with 11 kW.

Both variants are united by their design, which blends discreetly into different installation environments. Customers can also choose between the colors Polar and Graphite. The housing is UV and corrosion resistant and has protection class IP54, protection class II and impact resistance IK08. The wall boxes’ slim dimensions (29x29x11 cm) provide flexibility in planning and placement, even in limited spaces.

Easy installation and commissioning

The wall box can be mounted on the wall in a few simple steps.

It is attached to the wall using a mounting rail and drilling template, allowing for quick installation. A generously dimensioned mounting space creates sufficient space for both screwing and connecting supply, charging and data cables. Configuration and control is carried out using the specially developed Spelsberg Wallbox app, which is available free of charge for both iOS and Android. A five or seven meter long charging cable with type 2 plug is included in the scope of delivery.

High functionality

In the Pure version, configuration is possible via NFC, with the Smart Pro version also via the home network – wirelessly via WLAN or wired via Ethernet. The preset charging power of 11 kW can also be individually and easily adjusted via the application.

The Smart Pro variant has some extra features in connectivity and app integration. For example, the app provides an insight into the status of the current charging process: Using an integrated MID energy meter, the exact status of the charged energy and an overview of all charging processes in certain periods can be read and invoiced, if necessary. Pausing or continuing the charging process can also be managed conveniently on the spot via app control. In addition, updates are played in the background “over the air” on the wall box. Spelsberg is already in the process of planning further developments and additional functions, which should, for example, enable prioritized charging of individual wall boxes in a network or phase change for solar charging.

Display of changes and status changes

But not only the app’s surface provides information about the wall box and its charging processes. A multi-colored LED light on the box and acoustic signals indicate changes or status changes. Integrated DC residual current detection and temperature monitoring ensure maximum safety during charging. With professional installation, they offer protection for the vehicle, the house installation and the wall box.

The supplied RFID chips give users full control and effective protection against additional costs due to unauthorized third-party access to the wallbox. Thanks to the individual charging authorization, the box is locked or unlocked according to your own specifications.

Communication interfaces such as OCPP, Modbus and EEBus enable integration into and exchange with energy management systems or external systems from third-party providers. The prerequisites for direct connection of PV inverters for charging with solar energy are also indicated.

Smart Pro also presents itself as a suitable solution beyond the use of individual private households: if several wall boxes are installed on site, they can communicate with each other via LAN or WLAN to ensure a dynamic distribution of the available power and for to avoid critical overloads.
