description The utility model discloses a power battery pack and electric equipment. The power battery pack comprises a shell, a battery cell and a heat absorption piece, the shell is provided with an exhaust channel; the battery core is accommodated in the shell; the heat absorption part is contained in the shell and adjacent to the battery cell, the heat absorption part comprises a phase change material, and the phase change material is used for switching between at least two phases of a solid phase, a liquid phase and a gas phase and absorbing heat transferred to the heat absorption part by the battery cell in the phase change process. According to the power battery pack and the electric equipment provided by the utility model, heat generated in the operation process of the adjacent battery cells can be absorbed through the phase change of the phase change material, and the temperature of the battery cells is controlled within a normal range, so that the influence on the performance of the power battery pack due to th
