Abstract

A battery, a battery pack, and a vehicle are disclosed. The battery includes a housing having a sealed chamber, a core packaged in the sealed chamber, and a first terminal and a second terminal respectively mounted to the housing, where the first terminal is electrically connected to the housing, and the second terminal is insulated from the housing. The battery further includes a first tab and a second tab respectively led out from the core, the first tab being electrically connected to the housing, the first tab being electrically connected to the first terminal through the housing, and the second tab being electrically connected to the second terminal.

First claim

What is claimed is:

1. A battery, comprising:
a housing having a sealed chamber positioned within the housing,
a plurality of cores packaged in the sealed chamber, and
a first terminal and a second terminal respectively mounted to the housing,
wherein the first terminal is electrically connected to the housing, and the second terminal is insulated from the housing; and the battery further comprises a first tab and a second tab respectively led out from a first core of the plurality of cores, wherein the first tab is electrically connected to the housing through a first connection member, the first tab is electrically connected to the first terminal through the housing, and the second tab is electrically connected to the second terminal,
wherein the first connection member comprises a first U-shaped plate, wherein a closed end of the first U-shaped plate is disposed on the housing, an open end of the first U-shaped plate faces the sealed chamber, and the first tab is electrically connected the first U-shaped plate through a first lead-out sheet, wherein one end of the first lead-out sheet is connected to the first tab and a second end of the first lead-out sheet is connected to a wall of a formed opening of the first U-shaped plate, and wherein the wall of the formed opening of the first U-shaped plate is connected to a second core of the plurality of cores, and
wherein the housing comprises a cylindrical body with openings formed at both ends, a first sealing cover disposed at a lower end of the cylindrical body, and a second sealing cover disposed at an upper end of the cylindrical body; wherein the first tab is disposed at a lower end of the first core, and the second tab is disposed at an upper end of the first core.

2. The battery according to claim 1 , wherein the first tab is led out from one end of the first core, and the second tab is led out from the other end of the first core.

3. The battery according to claim 1 , wherein the second tab is electrically connected to the second terminal through a second connection member.

4. The battery according to claim 3 , wherein the second connection member comprises a second U-shaped plate, wherein a closed end of the second U-shaped plate is connected to the second terminal, an open end of the second U-shaped plate faces the sealed chamber, and the second tab is connected to a wall of a formed opening of the second U-shaped plate.

5. The battery according to claim 4 , wherein the second connection member comprises the second U-shaped plate and a second lead-out sheet, wherein the closed end of the second U-shaped plate is connected to the second terminal, the open end of the second U-shaped plate faces the sealed chamber, and the second tab is electrically connected to the second U-shaped plate through the second lead-out sheet; one end of the second lead-out sheet is connected to the second tab, and the other end of the second lead-out sheet is connected to the wall of the formed opening of the second U-shaped plate.

6. The battery according to claim 1 , wherein both the first terminal and the second terminal are mounted to the second sealing cover.

7. The battery according to claim 1 , wherein the first terminal is a positive terminal, and the second terminal is a negative terminal.

8. A battery pack, comprising a plurality of batteries according to claim 1 , the battery pack further comprising an external connection member configured to electrically connect the plurality of batteries.

9. A vehicle, wherein the vehicle is provided with the battery pack according to claim 8 .

10. The battery according to claim 1 , wherein the first lead-out sheet comprises a flexible connection sheet.

11. The battery according to claim 1 , wherein the second core has a corresponding first tab lead out from the second core, wherein the first tab of the second core is connected to the wall of the formed opening of the first U-shaped plate through a corresponding first lead-out sheet.
