Electric powertrain and charging safety
Charging faults can originate in the external supply, charge port, low-voltage battery, onboard charging hardware, temperature control, interlock or high-voltage isolation monitoring. An EV fault does not necessarily mean the traction battery has failed.
How a technician distinguishes the causes
Confirm the charging equipment and vehicle messages, then have appropriately trained personnel perform the approved safety assessment. Check the 12-volt supply and accessible non-high-voltage controls first. High-voltage isolation testing, opening packs or probing energized circuits is not appropriate without specialized qualifications and equipment.
Repair decisions and verification
Only offer high-voltage diagnosis or repair when the shop has confirmed training and equipment. After qualified repair, verify charging and thermal management under approved procedures.
What owners may notice. Folgore versions add high-voltage propulsion, charging and thermal management. A charging failure or power-system warning may not originate in the traction battery.
How the problem should be diagnosed. Separate external charger issues from 12-volt supply and high-voltage concerns; refer specialized testing to appropriately trained personnel.
Repair and safety considerations. Call to confirm high-voltage service availability.
