The invention relates to the technical field of automobile battery thermal management, and provides an automobile battery thermal management system, a control method and an automobile. The system comprises a battery pack, a first heater communicated with one end of the battery pack through a first pipeline provided with a first stop valve, a first three-way valve, and a low-temperature radiator; a water inlet of the first three-way valve is communicated with the other end of the battery pack, the water inlet of the first three-way valve is further communicated with the first pipeline through a second pipeline, and a second stop valve is arranged on the second pipeline; the first end of the low-temperature radiator communicates with a first water outlet of the first three-way valve, the second end of the low-temperature radiator communicates with the other end of the first heater, and a second water outlet of the first three-way valve communicates with the other end of the first heater. According to the automobile battery thermal management system provided by the invention, if the temperature of the first heater is too high, the cooling liquid enters the low-temperature radiator and cools the cooling liquid, and the cooled cooling liquid cools the first heater, so that a working fault caused by the too high temperature of the first heater is prevented.

    本申请涉及汽车电池热管理技术领域,提供了一种汽车电池热管理系统、控制方法及汽车,该系统包括:电池包;第一加热器,其通过第一管道与电池包的一端连通,第一管道上设有第一截止阀;第一三通阀,其进水口连通电池包的另一端,第一三通阀的进水口还通过第二管道与第一管道连通,第二管道上设有第二截止阀;低温散热器,其第一端连通第一三通阀的第一出水口,第二端连通第一加热器的另一端,第一三通阀的第二出水口连通第一加热器的另一端。本申请提供的汽车电池热管理系统,若第一加热器温度过高,冷却液进入低温散热器并对冷却液进行冷却,冷却后的冷却液对第一加热器进行冷却降温,进而防止第一加热器温度过高而产生工作故障。
