The disclosure relates to a battery module, a power battery pack, and a vehicle. The battery module includes a plurality of intermediate separators stacked in a left and right direction on the battery module, a plurality of cells, a mounting plate provided on a front side of the battery module, and a ventilator fixed on the mounting plate. The intermediate separator is provided with an intermediate heat-dissipation air plate, and an intermediate heat-dissipation air passage passing through a front and rear direction is formed inside the intermediate heat-dissipation air plate. Heat is exchanged between a left side face of the intermediate heat-dissipation air plate and a right side face of a cell on a left side of the intermediate heat-dissipation air plate, and is exchanged between a right side face of the intermediate heat-dissipation air plate and a left side face of a cell on a right side of the intermediate heat-dissipation air plate. The intermediate heat-dissipation air passage has a first tuyere and a second tuyere, a cavity is provided between the mounting plate and a front end face of the cell, the first tuyere leads to the cavity, and the second tuyere is provided on a rear side of the battery module and leads to outside of the battery module. The battery module in the disclosure has high heat dissipation efficiency, and can solve a heat dissipation problem during rapid charge/discharge (charge/discharge in a high rate of 3 to 6C).
