Common Faults
  1. Charging Port Malfunction
  2. Faulty Charging Cable or Connector
  3. Onboard Charger Issues
  4. Battery Management System (BMS) Errors
  5. Faulty Wall Connector or Charging Station
  6. Software Glitches
1. Charging Port Malfunction
Tools Required
  • Flashlight
  • Soft cloth or brush for cleaning
Repair Instructions

  1. Clean the Charging Port:

    • Use a flashlight to inspect for dirt or debris.
    • Gently clean the port using a soft cloth or brush. Ensure no moisture is present.
