The invention provides a sealing structure and a sealing method for a power battery and a vehicle body frame, and belongs to the technical field of electric vehicle structures. The sealing problem of the power battery and the vehicle body frame and the sound insulation problem of the installation gap between the power battery and the vehicle body frame are solved. The power battery assembly comprises a power battery, a vehicle body frame, detachable sealant, first EPDM closed-cell foam and second EPDM closed-cell foam, the power battery is connected with the vehicle body frame in a clearance fit mode, bolt installation faces are arranged on the two sides of the power battery, and the upper surface of an upper cover of the power battery and the bolt installation faces are in clearance fit with the vehicle body frame. A detachable sealant and first EPDM (Ethylene-Propylene-Diene Monomer) closed-cell foam are arranged in a gap between the upper surface of an upper cover of the power battery and a vehicle body frame, and second EPDM closed-cell foam is arranged in a gap between a bolt mounting surface of the power battery and the vehicle body frame. The sealing device is mainly used for sealing the power battery and the vehicle body frame.
