Abstract

A battery pack includes at least one battery cell, a protection circuit module electrically connected to the at least one battery cell, and a frame including the at least one battery cell and the protection circuit module. The battery pack also includes a label adjacent to the at least one battery cell, protection circuit module, and frame. The label includes a noise preventing portion in a direction different from a lengthwise direction of the frame.

Claims

1. A battery pack, comprising:

at least two battery cells;

a protection circuit module electrically connected to the at least one battery cell;

a frame including the at least two battery cells and the protection circuit module; and

at least one label adjacent to the at least two battery cells, protection circuit module, and frame, wherein the label includes at least one discontinuous portion extending in a direction different from a lengthwise direction of the frame and wherein the at least one discontinuous portion is between the at least one battery cell and a portion of the frame adjacent to the protection circuit module;

wherein the discontinuous portion includes at least one cut-out portion or includes a fabric-type label.

2. The battery pack as claimed in claim 1, wherein the at least one discontinuous portion includes a cut-out portion in the direction different from the lengthwise direction of the frame.

3. The battery pack as claimed in claim 1, wherein the at least one discontinuous portion includes a fabric-type label.

4. The battery pack as claimed in claim 3, wherein the fabric-type label includes an acetate material.

5. The battery pack as claimed in claim 1, wherein the at least two battery cells includes a first battery cell and a second battery cell, and wherein each of the first and second battery cells has at least one electrode tab.

6. The battery pack as claimed in claim 5, wherein the electrode tab of the first battery cell and the electrode tab of the second battery cell face each other, and are connected to the protection circuit module at opposing sides of the protection circuit module.

7. The battery pack as claimed in claim 6, wherein the frame includes:

a first frame section including a rectangular framework, the first frame section surrounding outer surfaces of the first and second battery cells connected to the protection circuit module, and

a second frame section coupled to the first frame section and having a plate shape covering a first surface of the protection circuit module.

8. The battery pack as claimed in claim 7, wherein the at least one label includes:

a first label covering a first surface of the first battery cell, a first surface of the second battery cell, and the second frame section, the first label including the at least one discontinuous portion; and

a second label covering a second surface of the first battery cell opposite to the first surface of the first battery cell and a second surface of the second battery cell opposite to the first surface of the second battery cell.

9. The battery pack as claimed in claim 8, wherein the first label includes a fixing portion adhered to a portion of the first frame section and fixing the first label.

10. The battery pack as claimed in claim 7, wherein the at least one discontinuous portion includes a first cut-out portion between the first battery cell and second frame section and a second cut-out portion between the second battery cell and the second frame section.

11. The battery pack as claimed in claim 7, wherein the at least one label includes:

a first label covering a portion of a first surface of the first battery cell and a portion of a first surface of the second battery cell;

a second label covering a second surface of the first battery cell opposite to the first surface of the first battery cell and a second surface of the second battery cell opposite to the first surface of the second battery cell; and

a third label that includes a fabric-type portion covering the second frame section.

12. The battery pack as claimed in claim 11, wherein the third label covers a portion of the first surface of the first battery cell adjacent to the second frame section and a portion of the first surface of the second battery cell.

13. The battery pack as claimed in claim 12, wherein:

the third label is made of an acetate fabric having warp threads and weft threads crossing each other, and

edges of the third label are at a predetermined angle relative to the warp threads and the weft threads, the predetermined angle being different from 90°

.

14. The battery pack as claimed in claim 11, wherein the third label includes a fixing portion adhered to a portion of the first frame section and fixing the third label.
