Battery module and battery pack

A battery pack, comprising:

• a battery module, wherein the battery module comprises cells and a cells contact system (CCS) assembly, and the CCS assembly comprises:
• a plastic bracket, wherein bar mounting positions for assembling bar monomers are provided at an upper side surface of the plastic bracket, and cell mounting positions for assembling the cells are provided at a lower side surface of the plastic bracket,
• wherein a positive electrode communication hole and a negative electrode communication hole are provided within a region of each of the cell mounting positions, and a glue filling hole is provided at at least one side of the positive electrode communication hole;
• and
• each of the cells is disposed corresponding to corresponding one of positive electrode communication holes, respectively, a gap between any of the cells and another cell adjacent to the any cell is defined as a glue filling cavity, and at least a portion of the glue filling cavity is exposed toward the upper side surface of the plastic bracket through the glue filling hole corresponding to the glue filling cavity.
