Possible Causes
Incorrect time or timezone set, Overlapping or disabled schedules, Vehicle also using its own schedule conflicting with charger, RTC drift without backup battery
How to Fix / Troubleshooting
Safety first: This is a control issue, not typically an electrical hazard.
- 1. Verify time:
- Check the charger’s internal clock and timezone settings.
- Correct them if inaccurate.
- 2. Review schedules:
- In the app or web interface, review all active schedules.
- Ensure they are enabled and not overlapping in a way that cancels charging.
- 3. Check vehicle settings:
- Disable the vehicle’s own charging schedule temporarily to avoid conflicts.
- 4. Test a simple schedule:
- Create a single, clear time window and observe if charging starts.
- 5. Firmware update:
- Update charger firmware if scheduling bugs are known and fixed in newer versions.
