Then, the heat pump component 400, the battery body 100, and the finished product temperature sensor 203 are connected to the corresponding power distribution and control module through corresponding data lines and wires. Then, it is convenient to operate the heat pump component 400 to supply heat.

Moreover, the related terms such as assembly connection in this application are common knowledge to those skilled in the art and can be implemented through various methods. Furthermore, no other special requirements are made in this application. It is only necessary to achieve the functions in this application. Therefore, no specific limitations are made here.

[0034] The high heat energy generated by the heat pump component 400 is input through the heat inlet head 201 with the cooperation of the inlet valve 420 and the return valve 430, and returned through the heat outlet head 202, thus forming a closed loop, which facilitates the circulation and supply of heat. At the same time, with the assembly of the inner grid 230, the heat medium is facilitated to form a uniform heat supply between the outer shell 210 and the inner shell 211, making it more convenient to heat the battery body 100. The finished product temperature sensor 203 facilitates the detection of heat entering and leaving the battery, which allows for real-time monitoring of the temperature for subsequent control. The operation ends here.
