Abstract

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.

Description

technical field [0001] The present disclosure relates to the technical field of vehicle engineering, in particular, to a cooling control method and system, and an electric vehicle. Background technique [0002] The heat dissipation of vehicle loads of electric vehicles is very important, especially the high-voltage loads of vehicles, such as power batteries and drive motors. Generally, the vehicle load heat dissipation of electric vehicles adopts two methods: air cooling and water cooling. The air cooling method can mainly increase the contact area with the air and dissipate the heat of the vehicle load into the air, while the water cooling method is to set up cooling water pipelines. , the heat of the vehicle load is taken away by the water in the cooling water pipeline. It is of great significance to reduce the temperature of the vehicle load under various working conditions. Effectively reducing the temperature of the vehicle load can not only ensure the normal driving o...
