Document Type and Number:
WIPO Patent Application WO/2022/111556
Kind Code:
A1
Abstract:
A battery cooling system, a battery cooling control method, an apparatus and a storage medium. The battery cooling system is used for cooling a battery (8) and comprises a refrigeration loop, a cooling member (2), a throttling valve (3), an observation member (4), an HVAC assembly (5), a thermostatic expansion valve (6) with a stop function, and a controller. A refrigerant is introduced into the refrigeration loop. The cooling member (2) is arranged on the battery (8). The throttling valve (3) is arranged between a first outlet (12) and a second inlet (21), and the throttling valve (3) is used for adjusting the flow of the refrigerant entering the cooling member (2). The observation member (4) is arranged between the throttling valve (3) and the second inlet (21), and the observation member (4) is configured to to observe the state of the refrigerant flowing out of the throttling valve (3). The HVAC assembly (5) is configured to cool a passenger compartment. The thermostatic expansion valve (6) is arranged between the first outlet (12) and a third inlet (51), and the thermostatic expansion valve (6) is configured to stop a flow channel between the first outlet (12) and the third inlet (51) when the temperature of the passenger compartment is lower than a preset value. The battery cooling system can improve cooling efficiency of the battery (8) and has high safety.
