For example, the controller 160 calculates an average value for the temperature of the center of the battery cell tray stack 110 located in any one row or column of the tray rack 130 or the temperature difference between the center and the periphery. If the result is out of the standard range, the temperature of the region where the corresponding battery cell tray stack 110 is located is locally adjusted. Alternatively, when a region having a higher temperature than other regions occurs in some regions of the tray rack 130, the temperature of the region may be locally adjusted.

It takes less time and money, and the temperature difference can be precisely controlled.
- the controller 160 may further include artificial intelligence for temperature control.

- the artificial intelligence derives a temperature control algorithm from the learning data to minimize the temperature difference between the center and the outer portion of the battery cell tray stack 110 .
- the temperature control algorithm may relate to controlling the location and number of heaters or blower fans that are turned on or off and operation time of the heaters or blower fans.
- Artificial intelligence derives the temperature control algorithm according to the position, number, and temperature data of the battery cell tray stack to control the temperature.
- the artificial intelligence controls the temperature according to the algorithm and verifies the validity of the algorithm.
- This verification process may be performed by comparing the predicted temperature according to the derived temperature control algorithm with thermal image temperature data of the actual battery cell tray stack 110 . For example, after adjusting the temperature according to the derived temperature control algorithm, the temperature difference between the center and the outer portion of the battery cell tray stack 110 does not match the predicted result, or the difference in effect is greater than the temperature data according to the conventional conditions. If there is no , the stored training data is modified and updated. At this time, the reason why the algorithm is not valid can be analyzed by considering the experimental conditions input together with the stored data. As such, the present invention can precisely and efficiently control the temperature by machine learning the temperature control algorithm by artificial intelligence.
