The invention provides an electric drive cooling control method and device, electronic equipment and a storage medium, and belongs to the technical field of new energy automobiles. The method comprises the following steps: acquiring reference parameters, wherein the reference parameters comprise a current torque value of a driving motor, a torque estimated value corresponding to a preset time node of the driving motor and a torque change rate; based on the reference parameters, determining the cooling flow required at present and the cooling flow required by the preset time node; and the actual output flow of cooling liquid used for cooling an electric drive system is adjusted based on the currently needed cooling flow and the cooling flow needed by the preset time node, and the electric drive system comprises a drive motor and a motor controller. By means of the method, the appropriate cooling liquid flow can be smoothly provided in time, so that the cooling requirement of the electric drive system is rapidly and stably met, the problems that the cooling liquid is not provided in time, and the cooling liquid flow changes suddenly are solved, the damage probability of the electric drive system is reduced, and the service life of the electric drive system is prolonged.
