However, the lithium ion battery has high sensitivity to temperature, and the charge-discharge capacity, cycle life, safety and the like of the lithium ion battery are directly affected by the temperature.

The existing battery module generally only considers the problem of heat dissipation, and the heating consideration is less. Heat dissipation typically includes both air cooling and liquid cooling. The air cooling mode has a simple structure, but has the problems of poor temperature consistency among the single batteries and low heat dissipation efficiency. Liquid cooling is generally a method of arranging liquid cooling plates and cooling pipes in a battery module in such a manner that the heat conduction contact area is limited, the process and assembly are complicated, the number of connection accessories is large, and the problems of insulation and waterproof grade need to be solved. At present, the protection of the battery in the aspect of temperature rise is not generally considered, so that the service life and the discharge power of the battery in a low-temperature state have serious problems.

In view of the above, it is desirable to provide a new heat exchange battery box to overcome the above-mentioned drawbacks.
