This invention discloses a stall protection method, device, equipment, and storage medium for an electric drive system. The scheme may include: acquiring the initial temperature of the IGBT module in the motor controller and the starting torque of the motor when the motor enters the starting state; defining a number of time nodes sequentially, with the moment when the motor enters the starting state as the zero point; for the number of time nodes, provided that the empirical temperature rise value of the IGBT module is less than the temperature rise margin, if it is detected that there is no time node in the number of time nodes where the actual speed of the motor exceeds the speed threshold of the motor in the running state, then if the torque of the motor is not zero, the starting state of the motor is maintained; if the torque of the motor becomes zero, the shutdown mode is entered; when it is detected that the empirical temperature rise value of the IGBT module corresponding to a second time node in the number of time nodes is greater than or equal to the temperature rise margin for the first time, the stall condition of the motor is reported, and the motor is shut down.
