The invention relates to the technical field of power batteries, and provides a battery box and a vehicle, the battery box comprises a first connecting piece and a plurality of battery modules, each battery module comprises a support plate and a plurality of battery cells, the plurality of battery cells are laid on at least one side surface of the support plate, the battery cells are connected to the support plate, and the first connecting piece is connected with the first connecting piece. The plurality of battery modules are stacked in the direction far away from the plane where the supporting plate is located and are connected through the first connecting pieces. The battery box does not need a battery frame body, the supporting plate occupies a small volume, the structural layout of the battery cells is compact, and the energy density of the battery box is increased. And corresponding battery frame bodies do not need to be customized according to different electric quantity requirements, so that the production cost of the battery box is reduced.
Description
technical field [0001] The invention relates to the technical field of power batteries, in particular to a battery box and a vehicle. Background technique [0002] With the development of new energy electric technology and people's attention to environmental issues is getting higher and higher. With its technical advantages of no pollution and zero emissions, electric vehicles have become a new development direction for the automotive industry. In addition to the common use of batteries as driving energy for ordinary cars, more and more engineering vehicles also use batteries as driving energy, such as electric heavy trucks. The power source of the electric vehicle comes from the power battery pack installed on the vehicle body, that is, the battery box. [0003] The current battery box usually includes a battery frame and a plurality of standard battery packs. The battery frame is used to load a plurality of standard battery packs. Each standard battery pack is fixed on t...
