Abstract

The present disclosure relates to a terminal protection cover and a battery module, the terminal protection cover includes a base portion, including a peripheral region and provided with base openings at the peripheral region; and a side wall, connected to the peripheral region and extending in a first direction, wherein the side wall is provided with two or more groups of side openings spaced apart from each other and extending in the first direction, and at least one base opening is located between adjacent two groups of side openings such that a portion of the side wall can be removed by means of the at least one base opening and the adjacent two groups of side openings. The present disclosure can prevent accidents such as short circuit of the modules or electric shock of an operator during transportation of the battery modules, without affecting the connection between the battery modules.

First claim

What is claimed is:

1 . A terminal protection cover for a battery module, comprising:
a base portion, comprising a peripheral region and provided with base openings at the peripheral region; and a side wall, connected to the peripheral region and extending in a first direction, wherein the side wall is provided with two or more groups of side openings spaced apart from each other and extending in the first direction, and at least one base opening is located between adjacent two groups of side openings such that a portion of the side wall can be removed by means of the at least one base opening and the adjacent two groups of side openings.

2 . The terminal protection cover according to claim 1 , wherein,
the base opening is formed as a blind slot recessed into the base portion in a thickness direction of the base portion.

3 . The terminal protection cover according to claim 1 , wherein,
the base opening is formed as a through slot extending through the entire base portion in a thickness direction of the base portion.

4 . The terminal protection cover according to claim 1 , wherein,
between adjacent two groups of side openings, there is disposed one base opening.

5 . The terminal protection cover according to claim 1 , wherein,
between adjacent two groups of side openings, there are disposed two or more base openings spaced apart from each other.

6 . The terminal protection cover according to claim 1 , wherein,
each group of side openings comprises one or more side wall slots recessed into the side wall in a thickness direction of the side wall, and in the case that each group of the side openings comprises two or more side wall slots, the two or more side wall slots are spaced apart in the first direction.

7 . The terminal protection cover according to claim 6 , wherein the side wall slot is formed as a blind slot.

8 . The terminal protection cover according to claim 6 , wherein the side wall slot is formed as a through slot extending through the entire side wall in the thickness direction of the side wall.

9 . The terminal protection cover according to claim 1 , wherein the side wall is formed into a circular cylinder or an elliptical cylinder.

10 . The terminal protection cover according to claim 9 , wherein,
the terminal protection cover comprises two or more base openings, and the two or more base openings are respectively located between adjacent two groups of side openings.

11 . The terminal protection cover according to claim 1 , wherein,
the side wall comprises three or more sub-side plates, each of which comprises two side connecting edges opposite to each other and extending in the first direction, wherein the three or more sub-side plates are connected to each other through the side connecting edges to form a prism, and the side openings are disposed adjacent to the side connecting edges.

12 . The terminal protection cover according to claim 11 , wherein,
the terminal protection cover comprises three or more groups of side openings, and the three or more groups of side openings are respectively disposed adjacent to the side connecting edges of the three or more sub-side plates; and the terminal protection cover comprises three or more base openings, and the three or more base openings are respectively located between adjacent two groups of side openings.

13 . A battery module, comprising:
a plurality of unit cells stacked in a second direction; an end plate, disposed on one side of the plurality of unit cells in the second direction and provided with a limit through slot at an end in the first direction; an upper cover, disposed on one side of the plurality of unit cells in the first direction, wherein the upper cover is provided with a groove disposed corresponding to the limit through slot; an output component, comprising a limit terminal and an output terminal continuously connected to each other, wherein the limit terminal is located in the limit through slot and the output terminal is located in the groove; and a terminal protection cover according to claim 1 , covering the output terminal and located in the groove.

14 . The battery module according to claim 13 , wherein,
the side wall of the terminal protection cover is provided with a snap component such that the terminal protection cover can be secured to at least one of the output terminal and the upper cover by the snap component in a snap fit manner.

15 . The battery module according to claim 14 , wherein,
the groove comprises a first inner wall, a second inner wall, a third inner wall and a bottom wall, wherein the first inner wall and the second inner wall are disposed opposite to each other and are connected by the bottom wall, and the bottom wall is provided with a mating snap member; and the snap component comprises a first snap member disposed toward the third inner wall, and the first snap member is fitted with the mating snap member such that the terminal protection cover can be secured to the upper cover via the first snap member and the mating snap member in the snap fit manner.

16 . The battery module according to claim 14 , wherein,
the snap component comprises two or more second snap members spaced apart in a circumferential surface of the side wall; and the output component is provided with two or more matching snap members on an outer surface, and the two or more matching snap members are respectively disposed corresponding to the two or more second snap members such that the terminal protection cover is secured to the output terminal via the two or more second snap members and the two or more matching snap members in the snap fit manner.

17 . The battery module according to claim 13 , wherein,
the base opening is formed as a blind slot recessed into the base portion in a thickness direction of the base portion.

18 . The battery module according to claim 13 , wherein,
the base opening is formed as a through slot extending through the entire base portion in a thickness direction of the base portion.

19 . The battery module according to claim 13 , wherein,
between adjacent two groups of side openings, there is disposed one base opening.

20 . The battery module according to claim 13 , wherein,
between adjacent two groups of side openings, there are disposed two or more base openings spaced apart from each other.
