Battery cooling system for automobile, control method and device of battery cooling system, storage medium and terminal

Abstract

The invention discloses a battery cooling system for an automobile, a control method and device of the battery cooling system, a storage medium and a terminal, the battery cooling system comprises a battery module, a three-in-one module and a cooling module, and the method comprises the steps that the working state of the three-in-one module is detected; when it is detected that the three-in-one module is started, the cooling module is controlled to operate in a corresponding operation mode according to the system temperature of the battery cooling system so as to cool the battery module and the three-in-one module; wherein different system temperatures correspond to different operation modes, and the refrigeration intensities of the cooling module under different operation modules are different. According to the scheme, cooling control over the three-in-one module can be achieved on the premise that the structure of an existing cooling system of an automobile is not changed, implementation is easy, additional power consumption is not increased, and energy saving is facilitated by adjusting the operation mode of the cooling module.

Description

technical field [0001] The present invention relates to the technical field of fuel cell electric vehicles, in particular to a battery cooling system for an automobile and a control method, device, storage medium and terminal thereof. Background technique [0002] Fuel Cell Electric Vehicle (FCEV) is a hybrid vehicle driven by a fuel cell and a battery. The three-in-one module is a relatively important component in the charging system of a fuel cell electric vehicle. [0003] Generally speaking, the charging system must be cooled down after it is activated. Without cooling at normal temperature, the temperature of the charging plate in the 3-in-1 module will rise above its limit after charging. At this time, the output of the three-in-one module will be throttled, affecting the charging effect. [0004] In order to cool the three-in-one module, the solution commonly used in existing fuel cell electric vehicles is to reuse the three-in-one module to the existing power cont...

Problems solved by technology

This leads to the fact that the PCU cooling system integrated with the function of cooling the three-in-one module must lower the upper limit temperature to meet the cooling needs of the three-in-one module, but in fact the PCU cooling system itself does not need to reach such a low temperature

[0008] In summary, the existing fuel cell electric vehicle cooling solution for the three-in-one module has defects, resulting in unnecessary power consumption and excessive changes to the original system of the vehicle, which is not conducive to actual implementation
