Normally, no additional RCD is required. However, an on-site assessment by a qualified electrician is recommended.

RFID cards can be obtained directly from ABL via our Customer Service. After creating a ticket on our website (https://www.ablmobility.de/en/service/support/), we will be very happy to take care of your request.

The access control via RFID of the Wallbox eM4 Single ensures that unauthorised persons cannot charge. Charging processes are only started and ended after successful authentication with taught-in RFID cards or keyfobs.

Dynamic load management enables optimal use of the available grid connection and increases the charging capacity. In addition, the main connection is protected against overload. With our ABL Energy Meter, dynamic load management can be realised with charging stations of the eM4 family. Up to 30 charging points can be connected to each other in a group installation.

If your preferred backend is not included in the list of our backend partners, we will be happy to perform the corresponding integration for you. Please contact our ABL Customer Service for this purpose.

The integration of the charging station into a backend enables full transparency of all charging processes. These can be viewed, managed and billed via a corresponding dashboard of the backend provider (e. g. app). The charging data is provided with precise kWh and time information.

No, it is not necessary to connect the charging station to a backend. In the case of a permanently assigned parking space (e. g. in an apartment building), connection to the user's own electricity meter is also possible. Consequently, charging processes are billed via the monthly electricity bill. However, a backend is required for the billing of charging processes of a company car in compliance with calibration law.

You can get expert advice from our electrical wholesale partners, electrical contractors and our ABL Sales Managers. If the charging station is to be installed in an apartment building, the property management company is also an important contact for all aspects of installation in your apartment building. Please note: The entire installation of the charging station must be carried out by a qualified electrical contractor.

Even with poor mobile phone reception in an underground car park, a connection to the backend can be established. This requires the integration of an LTE router into the network of the charging network.

When a charging process is completed at a charging station that is subject to a charge, no more electricity flows (0 kW). However, a parking fee will still be charged, as other electric vehicles will not be able to charge at this charging station.

The size of the supply line depends on the maximum charging current of the charging station and the length of the supply line. The supply line must be designed by a qualified electrician.

Every hardware manufacturer can offer different backend operators that are compatible with its charging stations. ABL offers the possibility to integrate almost any backend.

There are various communication options for establishing communication with the backend. Communication with the backend can either take place via LTE using a SIM card from the backend operator or by integrating an existing LAN connection. Communication via WLAN is also possible.
