Lithium battery is not electric when assembled, must be charged and activated, the first charge is called "chemical composition", which is used to activate the active material in the battery. "Container" is to charge and discharge the battery, detect the discharge capacity when the container is full, and determine the capacity of the battery. Only the battery with a capacity meeting or greater than the designed capacity is qualified. The process of selecting qualified batteries through capacity test is called container.

Therefore, it is crucial to ensure uniform heat dissipation of battery cells and modules during chemical composition and container, and to ensure the consistency of battery cells, which is related to the service life and safety of the battery system. When lithium battery is subjected to hot-pressing chemical composition and container, a large current needs to be passed between the positive and negative electrodes of each battery for charging and discharging. The voltage signal and temperature signal of each battery need to be collected. By charging and discharging the battery cell, the size of the battery cell capacity and internal resistance data are analyzed to determine the quality grade of the battery cell and group the battery cells to select the battery cells with the same electrical parameters for series and parallel connection.
