The battery pack in the electric automobile consists of a plurality of battery modules. Each battery module is provided with a plurality of batteries. The charge and discharge performance of the battery in the battery module is greatly affected by the temperature. Taking a lithium ion battery commonly used in the existing battery module as an example, the temperature of the lithium ion battery is kept within the range of 20-30 ℃, and the charge-discharge performance of the lithium ion battery is optimal; when the temperature is lower than 0 ℃, the phenomena of lithium precipitation by charging or power reduction by discharging are easy to occur; when the temperature of the lithium ion battery exceeds 45 ℃, the cycle life of the lithium ion battery is rapidly reduced, and safety problems such as thermal runaway and the like may occur.

Under the prior art, the temperature control of the battery is mostly realized by arranging a cooling plate and a heating plate in the battery pack. However, the battery box of the battery pack has a large volume, and a large amount of space is left between the battery module and the battery pack. Heating or cooling these plentiful spaces of the battery pack means energy waste. And the cooling plate and the heating plate are disposed on the battery module, the physical strength of the bottom plate of the battery module is generally insufficient. For example, in CN208256773U, the cooling plate is used as a load-bearing member of the battery module, and in this case, when the battery module moves, the batteries in the battery module can easily crush the cooling plate. Therefore, in the prior art, the cooling plate and the heating plate are generally disposed at the sides of the battery module, whereby the cooling plate and the heating plate do not need to bear the weight of the batteries within the battery module when the battery module is moved. For example, patent documents CN110534838A and CN109713178A both disclose this case. However, in this case, the cooling plate is easily crushed by the expansion of the battery at the end of its life. On the other hand, when the cooling plate and the heating plate are provided on the side, the efficiency of heating or cooling is not high.
