The invention relates to the technical field of vehicles, and discloses a vehicle, a vehicle heat circulation system and a control method thereof.The vehicle heat circulation system comprises a first valve body arranged among a heating device, an air conditioning device and a heat exchange device, and the first valve body is used for controlling the flow of first cooling liquid entering the air conditioning device and the heat exchange device; wherein when the cooling device works to cool the battery pack and the heating device works to supply heat to the passenger compartment, and the temperature of the second cooling liquid entering the battery pack is higher than the preset temperature, the heating device is controlled to stop working. Therefore, when the temperature of the second cooling liquid is higher than the preset temperature, the heating device is controlled to stop working, so that on one hand, the phenomenon of over-temperature of the battery pack caused by over-high temperature of the second cooling liquid can be reduced; and on the other hand, even if the temperature of the battery pack is over-high, the second cooling liquid can gradually recover to the normal temperature, so that the battery pack can be cooled, and treatment such as power degradation and power loss does not need to be carried out on the vehicle.

    本申请涉及车辆技术领域,公开了一种车辆、车辆热循环系统及其控制方法,车辆热循环系统包括第一阀体,设置于加热装置与空调装置和换热装置之间,第一阀体用于控制第一冷却液进入到空调装置以及换热装置的流量;其中,冷却装置工作对电池包降温且加热装置工作对乘员仓供热时,在进入到电池包的第二冷却液的温度高于预设温度时,控制加热装置停止工作。因此,在第二冷却液的温度大于预设温度时,通过控制加热装置停止工作,一方面能够减少第二冷却液温度过高导致电池包过温的现象;另一方面,即使电池包过温,由于第二冷却液会逐渐恢复到正常温度,能够实现对电池包的降温,不需要对车辆进行动力降级、动力丢失等处理。
