5 lug 2023 · The Proximity Pilot (PP) pin, also known as “plug present,” supports several functions. It serves to alert the vehicle's on-board charger (OBC) to the plug's presence and provides a signal to...
Learn how EVSE (electric vehicle supply equipment) and EV (electric vehicle) communicate via control pilot and proximity contact signals. The web page explains the functions, states and values of these signals according to IEC standard 61851-1.
Proximity pilot (PP): pre-insertion signaling; Control pilot (CP): post-insertion signaling; Protective earth (PE): full-current protective earthing system—6-millimetre (0.24 in) diameter; The allocation of the four normal power supply pins vary depending on the mode of operation. They are allocated as:

PP: Proximity Pilot. Contatto di segnalazione o linea di segnale nel cavo di ricarica tipo 2. Fornisce al veicolo le informazioni indicanti che è in corso la ricarica con una determinata corrente di ricarica, per cui viene attivato l'immobilizzatore.
Proximity Pilot (PP) serves as a charge cable detection and current limitation. The Proximity Pilot is implemented differently in Type 1 and Type 2 plugs. For Type 1 plugs only, the Proximity Pilot also takes care of mechanical locking and sparkleless disconnections.
The proximity pilot (PP) pin tells the charging equipment the type of cable connected to the socket – different cable thicknesses can cope with different amounts of electrical current. The control pilot (CP) pin provides bi-directional communications between the electric vehicle and charging system.
