The invention discloses a battery cooling system and a battery cooling control method. The battery cooling system is used for cooling a battery, and comprises a refrigeration loop, a cooling piece, athrottle valve, an observation piece, an HVAC assembly, a thermostatic expansion valve with a cut-off function, and a controller. A refrigerant is introduced into the refrigeration loop. A cooling piece is arranged on the battery. The throttle valve is arranged between the first outlet and the second inlet and used for adjusting the flow of the refrigerant entering the cooling piece. The observation piece is arranged between the throttle valve and the second inlet and used for observing the state of the refrigerant flowing out of the throttle valve. The HVAC assembly is used for cooling the passenger compartment. And the thermostatic expansion valve is arranged between the first outlet and the third inlet, and is configured to cut off the flow channel between the first outlet and the thirdinlet when the temperature of the passenger compartment is lower than a preset value. The battery cooling system can improve the cooling efficiency of the battery and has high safety.

    本发明公开了一种电池冷却系统及电池冷却控制方法,该电池冷却系统用于冷却电池,其包括制冷回路、冷却件、节流阀、观察件、HVAC组件、带截止功能的热力膨胀阀和控制器。制冷回路中通有制冷剂。冷却件设在电池上。节流阀设在第一出口与第二进口之间,节流阀用于调整进入冷却件中的制冷剂的流量。观察件设在节流阀与第二进口之间,观察件用于观察从节流阀流出的制冷剂的状态。HVAC组件用于对乘员舱降温。热力膨胀阀设在第一出口与第三进口之间,热力膨胀阀被配置为当乘员舱的温度低于预设值时截止第一出口与第三进口之间的流道。该电池冷却系统能够提高电池的冷却效率,并具有较高的安全性。
