Signal

Description

PlugPresent_Status

The proximity pin connection state of the cable/plug

PlugPresent_Voltage

The voltage measured at the proximity pin

PlugPresent_Resistance

The cable resistance value

PlugPresent_Wakeup

The wakeup state of the proximity pin signal

PlugPresent_SelfDiagnosticStatus

The self-diagnostic state of the proximity pin signal

Table 5-13 Proximity Pin Evaluation Signals

Functionality

Via the proximity pin the ECU starts from sleep mode if a cable is connected.

The VC-EVCC detects the wakeup caused by the proximity pin in the first 75ms after the

wakeup event. If the ECU is already running it cyclically checks if an inlet is connected

(PlugPresent_Wakeup).

Combo2 Inlet

The VC-EVCC interprets the measured voltage (PlugPresent_Voltage) to detect if a cable

is connected (PlugPresent_Status).

Caution

If the value of the internal resistor between PP and PE is configured to 4,7 kOhm, the

VC-EVCC will consider a Combo2 inlet connected and calculate the plug present

voltage accordingly.
