Controller

A charging station that controls and coordinates the activities of other stations (Extender) in the system. Only the Controller charging station includes a SBC which connects to the back end.

Controller+

A charging station in compliance with German calibration law that controls and coordinates the activities of other charging stations (Extender+). Compliant to German calibration law means that the measured data are saved for each individual charging process. Only the controller charging station includes a SBC which connects to the back end.

DC residual current monitoring module

DC fault currents can also occur in electric vehicles and can disable the protectiv e functions of common domestic power installations. Our module detects such fault currents and allows the wallbox to switch o the faulty charging circuit. We install this module in all of our ABL wallboxes as standard.

eHZ

(Electronic residential meter) Records the energy consumption of a charging pole, similar to a domestic power connection.

Electrical energy meter

Records the energy consumption of a charging outlet and provides the data to the back end for accounting purposes.

EVCC

(Electric Vehicle Charge Controller) communicates with the vehicle according to IEC 61851-1 Mode 3 and controls the flow of electricity to the vehicle.

Extender

One or more charging st ations that are connected to the Controller charging station via RS-485 field busses. The Extender charging station forwards all data required for charging to Controller charging station.

Extender+

One or more charging stations that are comliant to German calibration law and connected to the Controller+ charging station by RS-485 field buses. Compliant to German calibration law means that the measured data are saved for each individual charging process. The Extender+ charging station forwards all data required for charging to Controller+ charging station.

Internal electronic overcurrent protection

In addition to any upstream MCB, each outlet is provided with internal electronic overcurrent protection, which measures the current of each phase individually . If the measured current exceeds the maximum current of the outlet by more than 10% for 100 se conds or by 20% for 10 seconds, the charging current is automatically switched off for 60 seconds. This means that even charging cables whose rated current is less than the rated current of the MCB can still be used safely.

Internal temperature control

The temperature of the control circuit of each outlet is measured constantly . If it exceeds approx. 60°C, the charging is limited to 6A; at 80°C, charging is switched off completely until control circuit has cooled to 60°C again.

Load management

Distributes the available rated current among the charging outlets.

Logging Gateway

An in-house developed hardware and software that digitally signs the measured data and stores them tamper-proof for 8 years.

OCPP

(Open charge point protocol) Standardised communication interface between the charging point and the back end.

Phase current measurement

Measures the current intensities in the individual phases. With a difference greater than 20A, the charging power is throttled.

RFID

(Radio Frequency Identification Device) Access control using a touch-free transponder card.

SBC

(Single Board Computer) controls the components of the charge point, enables billing, remote control and monitoring by communicating with the backend via OCPP, provides load management and other functions.

Type 1 charging cable

Electric vehicle charging cable in accordance with SAE for countries with the single-phase power grid, such as Norway.

Type 2 charging cable

Electric vehicle charging cable in accordance with IECIEC 62196-2 for countries with the 3-phase power grid, such as Germany.

Overvoltage protection

Protects the charging outlets from overvoltage due to lightning strikes.
