Abstract

The embodiment of the invention discloses a cooling control method for a battery pack. The cooling control method comprises the step that GPS information of the geographic location where a vehicle islocated is obtained, road condition information of the vehicle at present and within a certain time in the future is obtained according to the obtained GPS information of the vehicle and map information; and whether future road condition needs to increase battery discharge capacity compared with current road condition or not is determined, if the future road condition needs to increase the batterydischarge capacity, cooling control is conducted on the battery pack in advance according to preset battery pack cooling conditions. According to the cooling control method for the battery pack, thebattery pack can be cooled in advance when needed, a battery working at the appropriate temperature is ensured, and cockpit temperature feeling is improved.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a battery pack cooling control method, device, system and vehicle. Background technique [0002] As the core component of pure electric vehicles or hybrid vehicles, the battery system is the only or main source of power for the vehicle and plays a decisive role in the performance of the vehicle. When the vehicle is in different driving conditions such as high speed, low speed, acceleration, deceleration, etc., the battery will be discharged at different rates, and heat will be generated at different heat generation rates. At the same time, if time accumulation and space effects are considered, a large amount of heat will be accumulated. cause the temperature of the battery pack to rise. The temperature rise in the battery pack seriously affects the operation of the battery's electrochemical system, cycle life and charge acceptability, battery pack power and energy, saf...
