5.2.1
Proximity Plug (PP)
The PP (Proximity Plug) signal detects if the charging connector is inserted or not.
5.2.2
Control Pilot (CP)
The CP signal (Control Pilot) is used for status detection between the charging station and
the electric vehicle in accordance with IEC 61851-1 and for digital communication. Digital
communication is necessary when charging in a Combined Charging System (CCS) in ac
-
cordance with IEC 61851-23, Annex CC, and DIN SPEC 70121.
Detailed charging parameters – used for charging the vehicle battery via the charging sta

tion – are exchanged via digital communication. The PWM signal on the Control Pilot is set
to a pulse duty factor of 5% in order to establish digital communication. Communication is
via a Powerline signal (HomePlugGreen PHY™), which is modulated to the Control Pilot.
Communication is established within the controller firmware and this is not accessible to us

Typical charging sequence
The DC charging sequence in a Combined Charging System (CCS) is divided into various
phases.
