Possible Causes

Blocked ventilation openings on EVBox enclosure, Direct sunlight or high ambient temperature, Failing internal temperature sensor, Loose thermal coupling between power components and heatsink

How to Fix / Troubleshooting

Safety: Overheating can damage electronics. If the enclosure is hot to the touch, stop using the charger until it cools and the cause is identified.

  • Check installation location: Ensure the EVBox is not installed in a confined, unventilated space or in direct sun without shading. Improve airflow or shading if necessary.
  • Inspect vents: Look for dust, spider webs, or debris blocking any ventilation slots. Clean gently with a soft brush or vacuum (power off).
  • Allow cooling: Turn off the charger at the breaker for 30 minutes to allow internal components to cool, then restore power and test.
  • Monitor during charging: Start a session and periodically feel the enclosure. It should be warm but not excessively hot. If E008 recurs quickly, internal thermal management may be compromised.
  • Internal check (qualified): With power off, open the unit and verify that temperature sensors are firmly attached to heatsinks or power modules and that all fans (if present) spin freely. Replace faulty sensors or fans as needed.
