CP_w004_proximityRationality
This alert is currently used for GB (Guobiao standard – Chinese) charge ports on Model S / X vehicles and PLCRLY electronic control units (ECU) in EU Model S / X vehicles.
The alert means the proximity voltage is outside of expected range. These are the expected ranges on vehicles with a GB charge port, the AC portion of the charge port, and the IEC type 2 charge ports:
- 4.291V to 4.620V – No cable in the GB AC charge port.
- 4.280V to 4.291V – GB cable in the GB AC charge port, and the button is being held down, meaning the connector is unlatched.
- 3.525V to 3.892V – 10A GB cable in the GB AC charge port.
- 2.995V to 3.275V – 16A GB cable in the GB AC charge port.
- 1.740V to 2.035V – 32A GB cable in the GB AC charge port.
- 1.020V to 1.220V – 63A GB cable in the GB AC charge port.
These are the limits for the DC portion of the GB charge port:
- For pin CC2:
- 4.5V to 5.5V – No cable in the GB DC charge port.
- 2.0V to 3.0V – Cable connected to the GB DC charge port.
- For pin CC1:
- 0.0V to 0.5V – No cable in the GB DC charge port.
- 5.5V to 6.5V – Cable connected to the GB DC charge port.
- 3.5V to 4.5V – Cable latched to the GB DC charge port.
Any voltage outside any of these voltage regions will cause a proximityRationality alert and prevent charging.
