AI Technical Summary
Technical Problem
In existing technologies, there is an inconsistency in the temperature of the individual cylindrical cells in a battery module, which leads to a decrease in cooling efficiency.
Method used
By setting multiple through holes at both ends of the module housing, the coolant flows along the axial direction of the cylindrical battery cell. Combined with the channel formed by the partition and support column, the coolant is evenly distributed, reducing the temperature difference between the battery cells.
Benefits of technology
It improves the uniformity of cell temperature, thereby enhancing the performance of the battery module and the stability of energy output.

Abstract
The utility model relates to the technical field of power batteries, and provides a battery module and a battery pack. The battery module comprises a module unit, the module unit comprises a module shell with a containing cavity and a plurality of battery cell units arranged in the containing cavity in the first direction, and each battery cell unit comprises a plurality of cylindrical battery cells sequentially arranged in the second direction; the axial direction of the cylindrical battery cell is consistent with the third direction; a plurality of through holes are respectively formed in the two ends of the module shell in the third direction, and a through hole is formed between any two adjacent cylindrical battery cells. According to the battery module disclosed by the utility model, the plurality of through holes are formed in the two ends of the module shell, and one through hole is formed between every two adjacent cylindrical battery cells, so that cooling liquid uniformly flows through the cylindrical battery cells along the axial directions of the cylindrical battery cells, the stable difference between the cylindrical battery cells can be reduced, the consistency of the temperature of the battery cells is favorably improved, and the service life of the battery cell is prolonged. Therefore, the use effect of the battery module is ensured.
