The present application relates to the technical field of new energy electric drive system control, and in particular to a differential protection method and apparatus, an electric vehicle, and a storage medium. The method comprises: acquiring a rotation speed difference between rotating speed half shafts in a differential and an output torque of a driving motor; matching a torque threshold of the driving motor according to the rotation speed difference, and determining whether the rotation speed difference is within a preset protection interval and whether the output torque is greater than the torque threshold; and when the rotation speed difference is within the preset protection interval and the output torque is greater than the torque threshold, activating a differential protection function of the differential, and using the differential protection function to reduce the output torque of the driving motor to a target torque; and otherwise, not activating the differential protection function. Thus, the problems in the related art of poor driving performance of a vehicle, poor user experience, and the like caused by being unable to avoid simultaneous activation of a differential protection function of a differential and a traction control system due to limitation of the differential protection function are solved.
