AI Technical Summary
Technical Problem
In the existing battery devices, the gap between the battery cell assembly and the box wall of the box is relatively large, which affects the energy density of the battery device.
Method used
By providing grooves in the direction of the end plate, the gripper can enter the grooves in the thickness direction of the box when grabbing the battery cell assembly, thereby overlapping on the projection surface perpendicular to the thickness direction of the box, reducing the space requirements between the box wall and the battery cell assembly.
Benefits of technology
The size of the battery cell assembly is improved so that it can be close to the box wall of the box, thereby improving the space utilization inside the box and enhancing the energy density of the battery device.

Abstract
The embodiment of the utility model provides a battery device and a power utilization device. The battery device comprises a battery monomer assembly and a box body, the battery monomer assembly comprises an end plate and a plurality of battery monomers, the plurality of battery monomers are arranged along a first direction, and the end plate is arranged at the end part of the battery monomer assembly in the first direction and is connected with the plurality of battery monomers. The battery cell assembly is contained in the box body, the box body comprises a first wall, and the first wall carries the battery cell assembly. Wherein the end plate is provided with a first surface deviating from the first wall, the first surface is provided with a groove, the groove is used for being connected with a grabbing piece so as to grab the battery monomer assembly, and the thickness direction of the first wall is perpendicular to the first direction. According to the technical scheme, the energy density of the battery device can be improved.
