Charging pole with external domestic power distribution box
The most important terms around the charging process
A server application that registers customer data, captures charging data and administers the charging station pool.DC fault current module.
DC fault currents,
which can take the protective function of ordinary domestic power installations out of action, can also occur with electric vehicles. Our module detects such fault currents and makes the wallbox switch the faulty charging circuit off. We integrate this module into all ABL Wallboxes as standard.
Electric energy meter
Captures the energy consumption of a charging point in order to provide the data to the backend for accounting purposes.
EVCC (Electric Vehicle Charge Controller)
communicates with the vehicle acc. to IEC 61851-1 Mode 3 and controls the flow of energy to the vehicle.
RCCB (Residual Current Circuit Breaker)
Protects from electric shock (personal protection).
eHZ (domestic power meter)
Captures the energy consumption of a charging pole as in a domestic grid connection.
Internal temperature monitoring
Continuously measures the temperature of the electronic control components of each charging point. If this temperature exceeds 60°C, the charging current is limited to 6A; at 80°C, the charging circuit is interrupted completely until the electronic control components have cooled back down to 60°C.
Internal electronic overcurrent protection
To complement an external upstream MCB, every charge point is fitted with internal electronic overcurrent protection, which measures the current for each individual phase. If the measured current exceeds the maximum current of the charging point by 10% for over 100s, or by 20% for over 10s, the charging circuit is automatically switched off for 60s. This means that charging cables with a rated current below the rated current of the MCB can also safely be used.
Type 1 charging cable
Vehicle charging cable acc. to SAE.
Type 2 charging cable
Vehicle charging cable acc. to IEC 69196-2.
Distributes the available rated current among the charging points.
MCB (Miniature Circuit Breaker)
Protects from an overload of electrical wires and from short circuit.
OCPP (Open Charge Point Protocol)
Standardized communication interface between charging point and backend.
RFID (Radio Frequency Identification Device)
Access control using contactless transponder cards.
Protects charging points from overvoltages due to lightning strikes.
