3.1 AC Charging Inlet Standards

The AC charging inlet standards for the different countries and regions are shown in Table 3-1. The charging inlet pin consists of charging signals and a power output. The charging signals are CP (control pilot), PP (proximity pilot), and CC (contact confirmation) signals. Among these signals, the CP signal is the handshake signal between the EV and the EV supply. The PP signal is used to detect the connection status between the charging gun and the EV. The CC functions the same as the PP and is only used in GB/T 18487.
