Possible Causes
Pilot signal voltage slightly out of spec, Incorrect resistor values on CP/PP circuits, Timing differences in contactor closure, Firmware not fully compatible with specific EV model
How to Fix / Troubleshooting
Safety first: If the vehicle refuses to charge, do not attempt to bypass safety circuits.
- Test with another EV: Connect a different vehicle to see if the issue is specific to one model.
- Check cable: Try a different Type 2 cable (if socketed) to rule out cable‑side tolerances.
- Firmware update: Update the Rolec charger to the latest firmware, which may include improved compatibility with newer EVs.
- Inspect CP/PP components (technician only): Verify that the pilot and proximity resistor values and wiring match Rolec’s design and the IEC 61851 standard.
- Consult Rolec/vehicle support: Provide logs and error messages to Rolec and the vehicle manufacturer; in rare cases, a hardware revision or PCB replacement may be recommended.
