The present invention relates to a battery pack structure, and provides a battery pack-vehicle body structure, which includes a battery pack and a vehicle body. The battery pack includes a battery cell module, and a first cooling plate and a second cooling plate for cooling the battery cell module. The first cooling plate and the second cooling plate are respectively located above and below the battery cell module. The battery pack is connected to the vehicle body such that the top of the first cooling plate forms a floor panel region of the vehicle body. The present invention further provides a battery pack and a vehicle. The battery pack-vehicle body structure provided by the present invention can solve a problem of an excessive temperature rise caused by high currents during fast charging without reducing the ground clearance of the vehicle and meet the requirements for the vehicle lightweight development.
