Possible Causes
Incorrect current setting in configuration, Vehicle drawing more current than allowed, Internal current sensor (CT) fault, Loose or undersized supply wiring causing voltage drop and false overcurrent detection
How to Fix / Troubleshooting
Safety: Overcurrent conditions can overheat wiring. If you smell burning or see discoloration, stop using the charger immediately.
- Step 1 – Check app settings: Open the Shell Recharge app or web portal and verify the maximum charging current is correctly configured for your circuit rating (e.g., 16 A or 32 A).
- Step 2 – Verify breaker rating: Confirm the MCB feeding the charger matches the configured current. Do not set the charger to a higher current than the breaker or cable rating.
- Step 3 – Try a lower current: Temporarily reduce the maximum current in the app (e.g., from 32 A to 16 A) and test if charging completes without E04.
- Step 4 – Inspect wiring (qualified person only): With power off, check that line and neutral conductors are correctly tightened in the terminal block and show no signs of overheating.
- Step 5 – If E04 persists at reduced current: The internal current transformer (CT) or measurement circuit on the control PCB may be faulty. Contact Shell Recharge support for diagnostics and possible board replacement.
