Secondly, related components connected to the battery pack generally need to be installed separately using brackets. If used in new energy vehicles or other vehicles where space is already limited, this results in additional space being occupied and costs increasing. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content
