Charge Port Pin Functions

Pin Number and Signal

1. 110V-220V AC (-)
2. 110V-220V AC (+)
3. Control Pilot
4. Proximity Detection
5. Ground
6. 400~1000V DC (-)
7. 400~1000V DC (+)

Pins 1, 2, and 5

These three pins are pretty much what you would find in a household outlet.

Pin 3

The Control Pilot (CP) pin communicates the charging status between the VCMS and charger.

• AC charging uses a pulse-width modulation (PWM) signal.
• DC charging uses PWM and a power line communication (PLC) signal.
• PLC signals include SOC, temperature, remaining charge time, and payment information.

Pin 4

The Proximity Detection (PD) pin communicates charge adapter connection:

• 4.45V = not connected
• 1.5V = connected
• 2.8V = V2L (Onboard Power Generator^*) adapted button pressed

Pins 6 and 7

These pins are used for DC Fast Charging^* current.
