Charger displays E13 and stops charging; may occur when the vehicle requests a current outside the charger’s capability.

Safety: This is a control/communication issue, not usually a high‑voltage failure. Still, turn OFF power before internal work.

• 1. Test with another vehicle:
  • If another EV charges normally, the issue may be with the original vehicle’s onboard charger.
• 2. Check charger current setting:
  • Ensure the maximum current configured in the AMPROAD app matches the circuit rating and charger model.
• 3. Firmware update:
  • Check for AMPROAD firmware updates that address pilot negotiation or compatibility.
  • Apply updates per manufacturer instructions.
• 4. Inspect pilot circuitry:
  • With power OFF, open the charger and inspect the pilot driver and sensing components on the control board for damage.
• 5. Replace control board if needed: If pilot circuitry is faulty and firmware is current, replace the AMPROAD main control board.
