[0082] Energy saving and emission reduction is the key to the sustainable development of the automobile industry. Electric vehicles have become an important part of the sustainable development of the automobile industry due to their energy-saving and environmentally friendly advantages. For electric vehicles, battery technology is an important factor for their development.

[0083] The space for installing the battery device on some electric vehicles is limited, for example, the engine needs to be installed on a hybrid vehicle, leaving little space for the battery device. This requires reducing the size of the battery device, especially in the height direction of the battery device. The battery device includes a battery monomer assembly and a high-voltage box, and the high-voltage box is arranged on one side of the battery monomer assembly, occupying the space of the battery device. Especially when the high-voltage box is arranged on one side of the battery monomer assembly along the height direction of the battery device, it will significantly increase the size of the battery device in the height direction. In the related art, in order to fully utilize the space inside the high-voltage box, the electrical components inside the high-voltage box are arranged compactly, and different electrical components are easily affected by each other, resulting in poor safety of the high-voltage box and the battery device.

[0084] Therefore, the battery device provided in the embodiments of the present application comprises a box body, a battery monomer assembly and a high-voltage box. The height direction of the box body is the first direction. The battery monomer assembly and the high-voltage box are arranged in the box body. The high-voltage box is located at one side of the battery monomer assembly along the first direction. The high-voltage box comprises a shell and a plurality of electrical assemblies arranged in the shell. The electrical assemblies comprise a plurality of electrical components. The plurality of electrical assemblies are arranged side by side and spaced apart along the second direction. The first direction is perpendicular to the second direction. The high-voltage box further comprises at least one first partition arranged in the shell. The first partition is arranged between two adjacent electrical assemblies along the second direction.

[0085] Through the above technical solution, the plurality of electrical assemblies of the high-voltage box are arranged side by side along the second direction, which is beneficial to reduce the size of the high-voltage box along the first direction (the height direction of the box body). In addition, the high-voltage box is located at one side of the battery monomer assembly along the first direction. The size of the high-voltage box along the height direction is reduced, which can reduce the space occupied in the height direction, thereby improving the internal space utilization rate of the battery device in the height direction, and further reducing the size of the battery device in the height direction. In addition, the plurality of electrical assemblies of the high-voltage box are arranged spaced apart along the second direction. The electrical components of different electrical assemblies are not easy to affect each other, which is beneficial to improve the safety of the high-voltage box and the battery device. The first partition can separate two adjacent electrical assemblies along the second direction, which is beneficial to avoid the mutual influence of the adjacent electrical assemblies along the second direction, thereby improving the safety of the high-voltage box, and further improving the safety of the battery device.

[0086] The technical solutions described in the embodiments of the present application are applicable to battery devices, energy storage devices using battery devices and electric devices using battery devices.

[0087] In the embodiments of the present application, the battery monomer can be a secondary battery, which refers to a battery monomer that can be activated by charging after discharging.
