Charger shows E08, charging stops shortly after starting, vehicle may show ‘charging interrupted’.

Safety first: Overcurrent conditions can cause overheating and fire. Isolate power before opening the charger.

• 1. Verify configuration:
  • Access the Heidelberg charger configuration (via DIP switches, web interface, or app depending on model).
  • Ensure the maximum charging current is set according to the supply circuit rating and installation manual.
• 2. Inspect tethered cable and plug:
  • Check for hot spots, discoloration, or a burning smell along the cable and at the Type 2 plug.
  • If any damage is found, replace the tethered cable assembly.
• 3. Check terminal tightness:
  • Open the housing and inspect all high‑current terminals (input, contactor, output).
  • Retighten to specified torque to prevent arcing.
• 4. Inspect current sensor:
  • Locate the current transformer (CT) or shunt on the power board.
  • Ensure the conductors pass correctly through the CT and that connectors are secure.
• 5. Test with reduced current:
  • If possible, temporarily reduce the maximum current setting and test a short charge.
  • If E08 no longer appears at lower current, suspect cable or terminal heating and address accordingly.
