Resumen de: EP4668442A1
The invention provides a battery box capable of being stacked layer by layer and a battery system. The battery box is configured as a box structure. Threaded holes are circumferentially formed in an upper portion of the battery box, and unthreaded screw mounting holes corresponding to the threaded holes are formed in a lower portion of the battery box. Screw fasteners penetrate through the unthreaded screw mounting holes of an upper battery box and the threaded holes of a lower battery box to fixedly connect the upper battery box and the lower battery box. A battery frame is eliminated, and the upper battery box is directly stacked on the lower battery box, such that the space utilization of battery boxes in the battery system is greatly increased, and a vehicle can be loaded with more batteries under the same volume; by adopting this technical solution, the cooling system can also exert a benefit effect on the tops of batteries, thus improving heat management efficiency; in addition, the technical solution facilitates connection of wires and water lines between the battery boxes.
