5 Signal contacts and charging sequences
5.1 AC charging
The sequence of processes involved in AC charging is based on standard IEC 61851 - 1,
Annex A.
5.1.1 Proximity Plug (PP)
The Proximity Plug is used to detect a charging connector in the charging station, and to de -
termine its current carrying capacity.
Figure 5 - 1 Proximity Plug (PP) circuit
The current carrying capacity is identified in accordance with IEC 61851-1 via resistor Rc.
The device measures the resistance value via the PP (Proximity Plug) signal and deter
-
mines the current carrying capacity of the connected charging cable.
The coding of the permissible current for the resistance value is defined in IEC 61851-1.
The PP signal is only relevant for charging stations with an infrastructure charging socket
(connection case B, see Section 5.1.3 ).
The PP signal has no relevance for charging stations with a vehicle connector (connection
case C, see Section 5.1.3 ) and is ignored.
