Conductive fibrous shavings from the slip ring assembly of the drive motors may cause a short circuit between the two slip rings, resulting in an overcurrent detected in the inverter. As a result, engine torque is cut to protect internal components of the controller, resulting in a loss of drive and potentially an “EV System Off” display on the dashboard, increasing the risk of an accident.
