Possible Causes
Disabled or misconfigured NTP synchronization, Depleted RTC backup battery, Faulty RTC oscillator on main board, Intermittent network connectivity preventing time updates
How to Fix / Troubleshooting
Safety first: Timekeeping issues are low risk; isolate power only if opening the unit.
- 1. Enable NTP: In the charger’s settings, enable automatic time synchronization and configure a reliable NTP server.
- 2. Check network: Ensure the charger has stable internet access so it can reach the NTP server.
- 3. Replace RTC battery: If the clock resets after power outages, replace the RTC backup battery on the main board.
- 4. Manual time set: As a temporary measure, manually correct the time and adjust schedules.
- 5. Replace main board: If the clock drifts excessively even with a new battery and NTP disabled, the RTC oscillator may be faulty; replace the main control board.
