Possible Causes
Failing low-voltage power supply, Loose low-voltage harness, Firmware instability, Overheating of main control board
How to Fix / Troubleshooting
Safety first: Turn OFF power before opening the charger.
- 1. Note conditions: Observe whether reboots occur during high temperature, high load, or randomly. This helps isolate thermal vs. electrical causes.
- 2. Power cycle and firmware update: Perform a full power cycle and check for available firmware updates from Besenergy.
- 3. Internal inspection (qualified): With power OFF, open the charger and reseat all low-voltage connectors between the power supply, main board, and display.
- 4. Check for overheating: Inspect the main board for discoloration or warped components. Ensure the cooling fan and heatsinks are functioning properly.
- 5. Replace power supply or main board: If reboots persist, replace the low-voltage power supply module first; if that does not resolve the issue, replace the main control board.
When to call a professional: For internal diagnostics and board replacement, contact a qualified technician.
