Abstract
The application provides a battery device and a vehicle. The battery device comprises a box body and a battery cell. The box body comprises a frame and a cross beam and a longitudinal beam arranged in the frame. The cross beam, the longitudinal beam and the frame define a plurality of spaced-apart accommodation spaces, at least part of the accommodation spaces being formed as battery spaces. The battery cell is arranged in groups in the battery spaces. A reinforcing member is arranged between the cross beam and the longitudinal beam, and / or between the cross beam and the frame, and / or between a first beam extending in a first direction of the frame and a second beam extending in a second direction of the frame, the first direction and the second direction having an included angle. Thus, the weight of the battery device can be reduced, the number of parts can be reduced, the cost can be reduced, the space occupation can be improved, the energy density of the battery device can be improved, the grouping efficiency of the battery cell can be improved, the structural strength of the battery device can be improved, and the structural stability and reliability of the battery device can be improved.
