BATTERY MODULE, BATTERY PACK AND ELECTRIC DEVICE

WIPO Patent Application WO/2024/078177

A1

A battery module, a battery pack and an electric device. The battery module comprises: at least one cell group and at least one thermal management assembly. The cell group comprises a plurality of cells, which are arranged in a first direction. The thermal management assembly comprises a cooling portion, wherein the cooling portion comprises at least two liquid cooling pipelines, and the at least two liquid cooling pipelines extend in the first direction. The thermal management assembly further comprises an elastic thermal conduction portion, and the elastic thermal conduction portion wraps and is connected to outer walls of the at least two liquid cooling pipelines, and is connected to at least one wall of the cell group. In this way, the structural stability of the liquid cooling pipeline can be improved, preventing the liquid cooling pipeline from breaking or deforming by being squeezed during the process of breathing-like expansion when the cells charge or discharge. In addition, the cooling efficiency can be improved.
