Charger shows E018; display may indicate 'RTC Error' or 'Clock Fault'. Charging may still work but scheduling fails.

Safety first: No high-voltage work is required for this issue.

• Sync time: Connect the charger to the Autel cloud via Wi-Fi or Ethernet and allow it to synchronize time automatically.
• Manual time set: Use the app or local interface to manually set the correct date and time, then reboot the charger.
• Firmware update: Check for and install any available firmware updates that address RTC issues.
• Board service: If E018 persists and scheduling remains unreliable, the RTC circuit or backup battery on the main control board may be defective. Board replacement is typically required.
