Abstract

A battery assembly device for a battery jump starting device. The battery assembly is configured to maximize electrical conductivity from a battery pack of the battery jump starting device to a battery to be recharged.

First claim

The invention claimed is:

1. A rechargeable battery assembly device for use in a battery jump starting device, the battery jump starting device having a positive battery cable and a negative battery cable, the rechargeable battery assembly device comprising:
a lithium ion rechargeable battery pack comprising a positive terminal tab located on one end of the lithium ion rechargeable battery pack and a negative terminal tab located on an opposite end of the lithium ion rechargeable battery pack;
a positive terminal conductor bar comprising a first portion that extends along a width of the lithium ion rechargeable battery pack, the positive terminal conductor bar soldered or welded to the positive terminal tab of the lithium ion rechargeable battery pack, the first portion of the positive terminal conductor bar having an outer end extending beyond the width of the lithium ion battery pack and electrically connected or connectable to the positive battery cable, the positive terminal conductor bar further comprising a second portion that extends a first distance along a length of the lithium ion rechargeable battery pack; and
a negative terminal conductor bar comprising a first portion that extends along a width of the lithium ion rechargeable battery pack, the negative terminal conductor bar soldered or welded to the negative terminal tab of the lithium ion rechargeable battery pack, the first portion of the negative terminal conductor bar having an outer end extending beyond the width of the lithium ion battery pack and electrically connected or connectable to the negative battery cable, the negative terminal conductor bar further comprising a second portion that extends a second distance along the length of the lithium ion rechargeable battery pack, wherein the second distance is greater than the first distance.

2. The rechargeable battery assembly device according to claim 1 , wherein both the positive terminal conductor bar and negative terminal conductor bar have rectangular-shaped cross-sections.

3. The rechargeable battery assembly device according to claim 1 , wherein the positive terminal conductor bar and the negative terminal conductor bar are oriented parallel relative to each other.

4. The rechargeable battery assembly device according to claim 1 , wherein an outer end of the positive terminal conductor bar wraps around an exposed conductor of an end of the positive cable.

5. The rechargeable battery assembly device according to claim 1 , wherein the lithium ion rechargeable battery pack is rectangular-shaped, and the positive terminal conductor bar and the negative terminal conductor bar are L-shaped and are bent around respective corners of the lithium ion rechargeable battery pack.

6. The rechargeable battery assembly device according to claim 1 , wherein the positive battery cable is connected to the positive terminal conductor bar by a cable portion.

7. The rechargeable battery assembly device according to claim 6 , wherein the cable portion comprises a flexible outer sleeve portion and a flexible inner sleeve portion.

8. The rechargeable battery assembly device according to claim 7 , wherein the flexible outer sleeve portion comprises an outer flange, and the flexible inner sleeve portion comprises an inner flange, the outer flange and inner flange sandwiching a casing wall of the battery jump starting device.

9. The rechargeable battery assembly device according to claim 6 , wherein the cable portion comprises an inner serpentine cable portion.

10. The rechargeable battery assembly device according to claim 9 , wherein the cable portion is configured to accommodate the positive battery cable oriented at an angle relative to the casing wall of the battery jump starting device, and the inner serpentine cable portion is configured to accommodate a misalignment between the angle relative to the casing wall and an angle of attachment of the inner serpentine cable portion with the positive terminal conductor bar.

11. The rechargeable battery assembly device according to claim 1 , wherein the rechargeable lithium ion rechargeable battery pack comprises a casing.

12. The rechargeable battery assembly device according to claim 1 , wherein the positive terminal conductor bar and negative terminal conductor bar are connected in electrical series with the rechargeable lithium ion rechargeable battery pack.

13. The battery jump starting device according to claim 1 , further comprising a smart switch connected to and controlling a smart switch interface.

14. The battery jump starting device according to claim 13 , wherein the smart switch interface comprises a circuit board having a first circuit board conductor bar spaced apart from a second circuit board conductor bar.

15. The battery jump starting device according to claim 14 , wherein the negative terminal conductor bar is connected to the first circuit board conductor bar.

16. A rechargeable battery assembly device for use in a battery jump starting device, the battery jump starting device having a positive battery cable and a negative battery cable, the rechargeable battery assembly device comprising:
a rectangular-shaped lithium ion rechargeable battery pack comprising a positive terminal tab located on one end of the rectangular-shaped lithium ion rechargeable battery pack and a negative terminal tab located on an opposite end of the rectangular-shaped lithium ion rechargeable battery pack;
a positive terminal conductor bar comprising a first portion that extends along a width of the lithium ion rechargeable battery pack, the positive terminal conductor bar soldered or welded to the positive terminal tab of the rectangular-shaped lithium ion rechargeable battery pack, the first portion of the positive terminal conductor bar having an outer end located at a side of the lithium ion battery pack and extending beyond the width of the lithium ion battery pack and electrically connected or connectable to the positive battery cable, the positive terminal conductor bar further comprising a second portion that extends a first distance along a length of the rectangular-shaped lithium ion rechargeable battery pack; and
a negative terminal conductor bar located on the opposite end and comprising a first portion that extends along the width of the lithium ion rechargeable battery pack, the negative terminal conductor bar having one end soldered or welded to the negative terminal tab of the rectangular-shaped lithium ion rechargeable battery pack, the first portion of the negative terminal conductor bar having an outer end located at the side of the lithium ion battery pack and extending beyond the width of the lithium ion battery pack and electrically connected or connectable to the negative battery cable, the negative terminal conductor bar further comprising a second portion that extends a second distance along the length of the rectangular-shaped lithium ion rechargeable battery pack, wherein the second distance is greater than the first distance.

17. The battery jump starting device according to claim 16 , further comprising a smart switch connected to and controlling a smart switch interface.

18. The battery jump starting device according to claim 17 , wherein the smart switch interface comprises a circuit board having a first circuit board conductor bar spaced apart from a second circuit board conductor bar.

19. The battery jump starting device according to claim 18 , wherein the negative terminal conductor bar is connected to the first circuit board conductor bar.
