The invention provides a control method and device of a stop valve, electronic equipment and a storage medium. The method comprises the steps that the temperature of a power battery, the request rotating speed of a compressor, the temperature of an evaporator, the current rotating speed of the compressor and the current on-off state of the stop valve are obtained; under the condition that the temperature of the power battery, the request rotating speed of the compressor, the temperature of the evaporator and the current on-off state of the stop valve meet preset conditions at the same time, a corresponding stop valve on-off request is generated; judging whether the rotating speed of the compressor is lower than a first preset threshold; under the condition that the rotating speed of the compressor is lower than a first preset threshold value, the pressure difference before and after the stop valve is calculated; and under the condition that the duration time when the pressure difference is lower than the second preset threshold value reaches the first preset time, the stop valve opening and closing request is controlled to be executed. By optimizing the allowable conditions and opportunities for opening and closing the stop valve, the abnormal sound generated when a refrigerant in the evaporator is suddenly increased or decreased can be reduced while the battery cooling performance and the passenger compartment cooling performance are guaranteed, and the NV performance of the air conditioner is guaranteed.

    本申请提供一种截止阀的控制方法、装置、电子设备及存储介质,该方法包括:获取动力电池的温度、压缩机的请求转速、蒸发器的温度、压缩机的当前转速和截止阀的当前开关状态;在动力电池的温度、压缩机的请求转速、蒸发器的温度和截止阀的当前开关状态同时满足预设条件的情况下,生成相应的截止阀开关请求;判断压缩机的转速是否低于第一预设阈值;在压缩机的转速低于第一预设阈值的情况下,计算截止阀前后的压力差;在压力差低于第二预设阈值的持续时间达到第一预设时间的情况下,控制执行截止阀开关请求。通过优化了截止阀打开和关闭允许条件及时机,在保证电池冷却和乘员舱冷却性能的同时,可降低蒸发器内冷媒突然增加或者减少时产生的异响,保证了空调NV性能。
