The housing assembly is provided with a first opening and a second opening communicating with the first space. The first connecting member is accommodated in the first space. The first connecting member is provided with a first channel. The first opening and the second opening communicate through the first channel. At least part of the cell assembly is arranged in the first space. In a first direction, projections of the first opening and the second opening are separated from a projection of the cell assembly. The first direction is a stacking direction of cells in the cell assembly. Heat of the cell assembly of the battery pack flows in the first channel through external air and is dissipated to the external environment, thereby improving the heat dissipation efficiency of the cell assembly.
