The invention relates to a cooling control method and system, and an electric vehicle, and aims to solve a problem of relatively high energy consumption caused by unreasonable control of an electronicfan and a cooling water pump. The method comprises the following steps: acquiring characteristic parameter information acquired by a data acquisition module for a vehicle load corresponding to the data acquisition module; determining a cooling level of the corresponding vehicle load according to the characteristic parameter information; obtaining a flow interval corresponding to the cooling waterpump and a rotating speed interval corresponding to the electronic fan according to the cooling level of the vehicle load; and adjusting the flow of the cooling water pump to the flow interval, and adjusting the rotating speed of the electronic fan to the rotating speed interval. The cooling level of the vehicle load can be determined, then whether the cooling water pump or the electronic fan isstarted or not is determined, the flow of the cooling water pump and the rotating speed of the electronic fan are adjusted, an endurance mileage of the electric vehicle is guaranteed, and vehicle energy management is optimized.

    本公开涉及一种冷却控制方法及系统,电动汽车,以解决电子风扇和冷却水泵控制不合理导致能耗较大的问题,包括:获取数据采集模块针对数据采集模块对应的车辆负载采集到的特征参数信息;根据特征参数信息确定对应的车辆负载的冷却等级;根据所述车辆负载的冷却等级得到所述冷却水泵对应的流量区间以及所述电子风扇对应的转速区间;将所述冷却水泵的流量调整至所述流量区间以及将所述电子风扇的转速调整至所述转速区间。可以确定车辆负载的冷却等级,进而确定是否开启冷却水泵或电子风扇,并调整冷却水泵的流量和电子风扇的转速,保证电动汽车的续航里程,优化整车能量管理。
