5 Signal contacts and charging sequences
5.1 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) wiring
The current carrying capacity is identified according to IEC 61851-1 by means of the Rc re-
sistor. The device measures the resistance value via the PP signal (Proximity Plug) and de-
termines 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.
Evaluation of the PP signal according to GB/T 18487.1
According to GB/T 18487.1, a charging connector is detected when S1/DIP 7 is set to ON,
and a resistance value of 0 Ω is detected on the Proximity Plug. According to GB/T 18487.1,
coding of the current carrying capacity on the charging station is not provided.
