Charger shows E11 and charging stops; may occur when the vehicle is unplugged during active charging.

Safety first: Always stop charging before unplugging the connector to minimize arcing. Do not wiggle or pull the connector under load.

• 1. Proper unplugging procedure:
  • Use the vehicle or charger stop button to end charging before disconnecting.
  • Wait for indicator lights to show that charging has stopped, then press the latch and remove the J1772 plug.
• 2. Inspect latch and contacts:
  • Check that the J1772 latch fully engages when plugged in.
  • Inspect the metal contacts for pitting or burn marks from arcing.
  • If contacts are heavily pitted, replace the cable assembly.
• 3. Cable strain relief:
  • Ensure the cable is supported and not pulling down on the connector during charging.
  • Use a hook or holder to reduce strain.
• 4. Internal arc detection circuit:
  • If E11 occurs even with proper use, the arc detection or monitoring circuit on the main control board may be overly sensitive or damaged.
  • Board replacement may be required.

If E11 appears only when unplugging under load, it is primarily a usage issue; follow correct disconnect procedures. If it appears randomly, have the charger inspected.
