The invention relates to a cooling control method and device of an electric drive system, a medium and equipment. The method comprises the following steps: determining the required heat dissipation power of the electric drive system; acquiring environment temperature and water temperature of a water inlet of the radiator; according to the required heat dissipation power, the environment temperature and the water temperature of the water inlet of the radiator, determining the rotating speed of a heat dissipation fan; and controlling the cooling fan to operate at the determined rotating speed. As the environment temperature and the water temperature of the water inlet of the radiator are considered, namely, the rotating speed of the cooling fan is adjusted according to the environment temperature and the water temperature of the water inlet of the radiator, cooling control over the electric drive system better meets actual requirements, redundant design of cooling is reduced, and energy consumption is reduced on the basis that normal operation of the electric drive system is guaranteed.

    本公开涉及一种电驱动系统的冷却控制方法和装置、介质、设备。所述方法包括:确定所述电驱动系统的需求散热功率;获取环境温度和散热器进水口的水温;根据所述需求散热功率、所述环境温度和所述散热器进水口的水温,确定散热风扇的转速;控制所述散热风扇以所确定的转速运行。由于考虑了环境温度和散热器进水口的水温,即根据环境温度和散热器进水口的水温来调节散热风扇的转速,使得对电驱动系统的冷却控制更加贴合实际需求,减小冷却的冗余设计,在保证电驱动系统正常运行的基础上,减少了能量消耗。
