Abstract

The disclosure discloses a battery and a battery apparatus. The battery includes two opposite first surfaces and four second surfaces disposed around the first surfaces, a pole assembly and a busbar. An area of the first surface is larger than an area of the second surface. The pole assembly is disposed on the first surface. The busbar is bent into a first segment and a second segment. The first segment is located at a side of the first surface where the pole assembly is disposed and is connected to the pole assembly. The second segment is parallel to or substantially parallel to a second surface and is used for electrically connecting the pole assembly of another battery.

First claim

What is claimed is:

1. A battery, comprising:
two opposite first surfaces and four second surfaces disposed around the first surfaces, an area of each of the first surfaces larger than an area of each of the second-surfaces;
pole assemblies, the pole assemblies disposed on one of the first surfaces; and
busbars, each of the busbars bent into a first segment and a second segment, wherein the first segment is located at a side of the one of the first surfaces disposed with the pole assemblies and is connected to the pole assemblies, and the second segment is parallel to one of the second surfaces and is used for electrically connecting assemblies of another battery,
wherein the first segment and the second segment form an angle between 80 degrees and 100 degrees, and
one of the busbars on one of the pole assemblies is bent away from the one of the first surfaces, and the other one of the busbars on the other one of the pole assemblies is bent toward a direction close to the one of the first surfaces.

2. The battery according to claim 1 , wherein an orthographic projection of the second segment on a plane where one of the first surfaces is located is located outside the one of the first surfaces.

3. The battery according to claim 2 , wherein a number of the pole assemblies is two, and a number of the busbars is two; the busbars are connected to the pole assemblies respectively.

4. The battery according to claim 1 , wherein the first segment is welded to one of the pole assemblies.

5. The battery according to claim 4 , wherein a thickness of a portion of the first segment welded on the one of the pole assemblies is smaller than a thickness of the second segment.

6. The battery according to claim 1 , wherein each of the busbars and each of the corresponding pole assemblies are integrally formed.

7. The battery according to claim 1 , wherein orthographic projections of the first segment and the one of the pole assemblies on one of the first surfaces at least partially overlap.

8. The battery according to claim 1 , wherein a length of the battery is a, a width of the battery is b, and a height of the battery is c, wherein 2b≤a≤50b, and/or 0.5c≤b≤20c; and
400 mm≤a≤2500 mm.
