3.4.7 Proximity Detection acc. to IEC 61851
Proximity defines an additional resistor attached to the connector of the charging cord, which indicates the
maximum ampacity of the cord. This resistor is measured by the charger and defines the amount of current
that the cord is allowed to conduct. This resistor is standardised and therefore independent of the
manufacturer. Due to Proximity Detection the charger can detect:

Whether a charging cable is connected to the vehicle

Which cable type is connected

Which amperage is possible with the charging cable (range of 6 -
63 A) The NLG6 charger generally limits the possible charging current
to max. 32 A.
INFORMATION
For this function, a 4.7 kΩ resistor must be integrated in the Charge Coupler! This must be provided
by the customer (refer to drawing).
3.4.8 Active discharge
The device features active discharge of circuits. As soon as the device is disconnected from the HV, the
internal HV circuits discharge:

at applied HV voltage 320 V = < 2.4 s to < 30 V

at applied HV voltage 420 V = < 4.7 s to < 30 V
