The cooling liquid expansion kettle 30 is communicated with the cooling circuit 40, and as the working temperature of the cooling liquid is generally between-40 ℃ and 100 ℃, the volume of the cooling liquid expands and contracts due to expansion and contraction, the cooling liquid expansion kettle 30 can store the part overflowed from the original cooling circuit 40 due to expansion of the cooling liquid, and can supplement the cooling liquid to the cooling circuit 40 when the volume of the cooling liquid is reduced due to temperature reduction.

Because the battery has the phenomenon of volume expansion under long-term use, the volume expansion part of the battery occupies the original cooling liquid flow channel, and the cooling liquid flows to the cooling liquid expansion kettle 30 more, so that the cooling liquid expansion kettle 30 needs to have a larger volume to cover the influence of the expansion of the cooling liquid caused by the volume increase of the battery in the cooling system 10.

The cooling fluid storage kettle 20 is in unidirectional communication with the cooling system 10, and the cooling fluid can flow from the cooling system 10 into the cooling fluid storage kettle 20 and cannot flow back from the cooling fluid storage kettle 20 to the cooling system.
