Abstract: This application provides a battery box, which includes: a heat exchange plate and a lower frame body located on the heat exchange plate. The lower frame body includes edge beams and internal beams, the edge beams forming a circumferential closure opened in an up-down direction, the edge beams and the heat exchange plate together forming an accommodating space with an upward opening, and the internal beams located inside the accommodating space and divide the accommodating space into sub-accommodating spaces for placing battery modules. The heat exchange plate is configured to support the battery modules and exchanges heat with batteries of the battery modules, and a bottom plane of an internal beam is partly in contact with a top plane of the heat exchange plate in the up-down direction.
