Likely Causes
  1. Onboard AC charger module internal component failure preventing charging session
  2. Input power quality issue such as voltage sag or frequency deviation at the EVSE
  3. Onboard charger overtemperature shutdown due to sustained maximum-rate AC charging
  4. Faulty ground fault detection circuit within the onboard charger triggering protective shutdown
  5. Communication failure between the onboard charger and the vehicle BMS
How to Fix It
1
Disconnect the charge cable and wait 5 minutes before attempting to reconnect
2
Try charging at a different Level 2 EVSE to rule out infrastructure power quality issues
3
Check whether the onboard charger fault code specifies a temperature or communication sub-fault
4
Attempt charging at a lower power level if the EVSE allows amperage adjustment
5
Schedule Polestar service for onboard charger module inspection and replacement
Pro Tip
This fix requires some technical knowledge. If you're unsure about any step, consider contacting support or a qualified technician.
