N2 - This paper proposes a winding-based discharge strategy with current sensor fault-tolerant capability for the high-voltage permanent magnet (PM) drivetrains used in electric vehicles (EV) after the crash. Firstly, the impacts of the current sensor scaling errors on the discharge performance are discussed clearly, posing the necessity of endowing the discharge algorithms with fault-tolerant capability. Secondly, a novel fault-tolerant winding-based discharge scheme that contains four stages, namely, topology reconstruction, fault detection, fault tolerance, and fault-tolerant winding-based discharge, is developed. In comparison with the traditional strategies, the proposed fault-tolerant method is easy to implement. Finally, simulation results prove that the proposed fault-tolerant strategies are effective.
