Abstract

A battery apparatus includes batteries arranged in a first direction; an end plate disposed at an end of the battery apparatus and having adjacent third and fourth surfaces; a protective support disposed on the end plate and having adjacent first and second surfaces. The first and third surfaces are disposed opposite to each other, and the second and fourth surfaces face the batteries; the fourth surface has an adhesive layer; the protective support has a notch at a junction of the first and second surfaces, and the notch is a first notch, and/or the end plate is provided with a notch at a junction of the third and fourth surfaces, and the notch is a second notch; a first (first notch and third surface), second (second notch and first surface), or third (first and second notches) combination forms a groove, and an opening of the groove faces the batteries.

First claim

What is claimed is:

1. A battery apparatus, comprising:
a plurality of batteries arranged in a first direction;
an end plate disposed at an end of the battery apparatus in the first direction; and
a protective support disposed on the end plate to protect an output terminal of the battery apparatus;
wherein the protective support has a first surface and a second surface adjacent to each other, the end plate has a third surface and a fourth surface adjacent to each other, the first surface and the third surface are disposed opposite to each other, and the second surface and the fourth surface face the batteries in the first direction;
the fourth surface is provided with an adhesive layer, wherein the adhesive layer is coated between the end plate and the batteries;
the protective support is provided with a notch at a junction of the first surface and the second surface, and the notch is a first notch, and/or, the end plate is provided with a notch at a junction of the third surface and the fourth surface, and the notch is a second notch;
a first combination or a second combination or a third combination forms a groove, an opening of the groove faces the batteries in the first direction, the first combination is the first notch and the third surface, the second combination is the second notch and the first surface, and the third combination is the first notch and the second notch; and
the first surface faces towards the third surface of the end plate along a direction perpendicular to the first direction and to an extension direction of the groove, and the first surface is in contact with the third surface.

2. The battery apparatus of claim 1 , wherein in the first direction, the second surface and the fourth surface are staggered in the first direction.

3. The battery apparatus of claim 2 , wherein in the first direction, the second surface is farther from the batteries than the fourth surface.

4. The battery apparatus of claim 1 , wherein the end plate is snap-fitted with the protective support.

5. The battery apparatus of claim 1 , wherein a cross-sectional shape of the notches is triangular or rectangular; and/or the junction of the first surface and the second surface has a chamfered structure; and/or the junction of the third surface and the fourth surface has a chamfered structure.

6. The battery apparatus of claim 1 , wherein in a second direction perpendicular to the first direction, the groove penetrates two ends of the first surface and/or the third surface.

7. The battery apparatus of claim 2 , wherein in a second direction perpendicular to the first direction, the groove penetrates two ends of the first surface and/or the third surface.

8. The battery apparatus of claim 3 , wherein in a second direction perpendicular to the first direction, the groove penetrates two ends of the first surface and/or the third surface.

9. The battery apparatus of claim 4 , wherein in a second direction perpendicular to the first direction, the groove penetrates two ends of the first surface and/or the third surface.

10. The battery apparatus of claim 6 , wherein the protective support comprises a high-voltage protective support and a low-voltage protective support, and the high-voltage protective support and the low-voltage protective support are an integrated structure.

11. The battery apparatus of claim 7 , wherein the protective support comprises a high-voltage protective support and a low-voltage protective support, and the high-voltage protective support and the low-voltage protective support are an integrated structure.

12. The battery apparatus of claim 8 , wherein the protective support comprises a high-voltage protective support and a low-voltage protective support, and the high-voltage protective support and the low-voltage protective support are an integrated structure.

13. The battery apparatus of claim 9 , wherein the protective support comprises a high-voltage protective support and a low-voltage protective support, and the high-voltage protective support and the low-voltage protective support are an integrated structure.

14. A battery module, wherein the battery module comprises the battery apparatus of claim 1 .

15. A battery pack, wherein the battery pack comprises the battery apparatus of claim 1 .

16. A battery pack, wherein the battery pack comprises the battery apparatus of claim 4 .

17. A battery pack, wherein the battery pack comprises the battery apparatus of claim 6 .
