Display shows E05 and charging stops shortly after starting; may occur intermittently.

Safety first: Turn OFF the breaker before opening the charger. Do not repeatedly reset if the breaker is tripping.

• 1. Check current setting: On Besenergy models with adjustable current (via buttons or app), verify that the maximum current is set appropriately for the circuit (e.g., 32A on a 40A breaker). Reduce the setting and test again.
• 2. Inspect output cable: Look for visible damage, kinks, or crushed sections. A partial short can cause overcurrent detection. Replace the cable if any damage is found.
• 3. Test with another vehicle: If possible, try charging a different EV. If E05 only occurs with one vehicle, the car’s onboard charger may be drawing irregular current and should be inspected by the vehicle manufacturer.
• 4. Internal inspection (qualified only): With power OFF, open the housing and locate the current transformer (CT) or shunt on the output lines. Check for loose connections or burnt components. Tighten terminals and replace any discolored wiring.
• 5. Replace faulty sensor or board: If the CT is cracked or the board around it is burnt, replace the current sensor assembly or main control board per Besenergy parts guidance.

When to call a professional: If you suspect internal sensor or board failure, or if breakers are tripping, contact a qualified technician.
