Proximity Pilot

A proximity pilot (PP) also known as the "plug present" pin is a pin connector on charging cables for electric vehicles. They are one of five pins on a type 1 connector and one of seven pins on a type 2 connector.

How does the proximity pilot work?

The proximity pilot pin works by signalling to the electric vehicle charger that the charging cable is securely connected and receiving power. If the connector is not connected properly the proximity pilot will disable charging and stop sending power to the vehicle as a safety precaution.
