The rapid adoption of electric vehicles coupled with high-voltage battery packs increases safety concerns, especially during crashes. Such concerns can be addressed voltage discharge strategies to reduce the DC-bus capacitor. One strategy involves injecting a negative current into traction motor dissipate energy through windings. issue involving injection d- and q-axis currents speed capacitor quickly is observation large surge due recovery from motor. A found in literature deals this piecewise calculation based on speed. This study investigates provides recommendations for improvement future work key insights. Using MATLAB Simulink 2023b, analysed compared other strategies. In certain circumstances high-rotor-inertia motor, performance was not deemed adequate. essence, lack testing multiple powertrains as one potential cause such problems which needs research.
