This article addresses the recent charging issues reported by BMW i4 owners following a firmware update. The problem involves the inability of the i4 to restart charging after a pause, particularly during surplus solar charging.
Overview
After a recent firmware update from BMW, several customers have reported that their i4 (all trim levels) can no longer restart a charge after it has been paused. This issue predominantly affects charging during surplus solar conditions, where the zappi charger might need to halt and then resume charging.
Test to Complete
To diagnose whether the issue is related to the zappi charger or the vehicle itself, conduct the following proof-of-concept test:
- Initial Charging: Plug the car into the charger and allow it to charge for a couple of minutes.
- Power Off: Switch off the charger at the wall.
- Wait Period: Leave the car connected for 10 to 15 minutes while the charger remains off.
- Power On: Turn the power to the charger back on and check if charging resumes.
- If Charging Resumes: This suggests that the issue might be specific to the vehicle's firmware. Please contact myenergi support for further assistance.
- If Charging Does Not Resume: This indicates that the issue is likely not related to the zappi charger.
