The invention is suitable for the technical field of motor control, and provides a fan speed regulation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a discrete relationship between an input quantity and a fan duty ratio and real-time data of a charging pile; the input quantity comprises the environment temperature, the load rate of the charging pile and the output voltage; according to the real-time data, relevant input quantity data and relevant fan duty ratio data in the discrete relation are determined; performing linear fitting by taking each input quantity as an independent variable and the duty ratio of the fan as a dependent variable in sequence according to the corresponding related input quantity data and the related duty ratio data of the fan to obtain a fitting relationship; based on the fitting relation, the final fan duty ratio is obtained, and the fan rotating speed is controlled. According to the method, the fitting accuracy can be improved, the final fan duty ratio related to the real-time data can be accurately obtained, the speed of the fan is adjusted, the speed adjusting continuity and effect of the fan are improved, and the requirement for reducing noise is better met on the premise that the heat dissipation and cooling requirements of the charging pile are met.
