Battery straps
View Patent ↗The present disclosure relates to a battery for use in various applications including starting, lighting, and ignition and other purposes in vehicles such as automobiles and boats. The disclosed battery design includes a number of battery cell elements connected in series by a number of straps. The present disclosure describes a system of connecting the cells that minimizes the size and weight of the straps and increases the operating efficiency of the battery.
1. A battery comprising:
a first, second and third battery cell provided in a first row;
a fourth, fifth and sixth battery cell provided in a second row opposite the first row;
a first battery strap electrically coupling the first and second battery cells;
a second battery strap electrically coupling the second and third battery cells;
a third battery strap electrically coupling the first and fifth battery cells;
a fourth battery strap electrically coupling the fourth and fifth battery cells; and
a fifth battery strap electrically coupling the sixth and third battery cells, wherein the battery straps electrically couple the battery cells of the first and second rows in series; and
wherein the battery straps are cast on to the battery cells and are positioned below a cover for the battery.
2. The battery of claim 1 further comprising:
a first battery terminal electrically coupled a cell at a first end of a sequence of electrically coupled cells formed by the battery straps;
a second battery terminal electrically coupled a cell at a second end of the sequence of electrically coupled cells formed by the battery straps; and
wherein the first terminal and second terminal are both located on the same side of a dividing line, and the first and second terminals each include an end strap, a portion of each end strap being provided adjacent to a perimeter of a battery container.
3. The battery of claim 1 wherein the battery cells and straps are contained in a housing and the terminals are located proximate to corners of a cover of the housing.
4. The battery of claim 1 wherein the battery has a front side, a back side, and two ends, each end is approximately equal to the width of two cells, the front and back sides are each approximately equal to the width of three cells, a first terminal is provided proximate to a first corner of the battery, the second terminal is provided proximate to a second corner of the battery, and the first corner and second corner are both proximate to the same side of the battery.
5. The battery of claim 1 further comprising:
a first battery terminal electrically coupled to a cell at a first end of a sequence of electrically coupled cells formed by the battery straps;
a second battery terminal electrically coupled to a cell at a second end of the sequence of electrically coupled cells formed by the battery straps; and
wherein the first terminal and second terminal are located on the same side of a dividing line provided between the first row of battery cells and second row of battery cells.
6. The battery of claim 1 wherein a dividing line divides the first row of battery cells and the second row of battery cells, and no more than two of the battery straps cross the dividing line.
7. The battery of claim 1 wherein a dividing line divides the first row of battery cells and the second row of battery cells, and the third and fifth battery straps cross the dividing line.
8. A battery comprising:
six cylindrical battery cells having a top side comprising:
a first, second and third battery cell provided in a first row;
a fourth, fifth and sixth battery cell provided in a second row opposite the first row;
five battery straps comprising:
a first battery strap electrically coupling the first and second battery cells;
a second battery strap electrically coupling the second and third battery cells;
a third battery strap electrically coupling the first and fifth battery cells;
a fourth battery strap electrically coupling the fourth and fifth battery cells; and
a fifth battery strap electrically coupling the sixth and third battery cells, wherein the battery straps electrically couple the battery cells of the first and second rows in series; and
wherein the third strap is longer than the first, second, fourth, and fifth straps.
9. The battery of claim 8 wherein the battery has a front side, a back side, and two ends, each end is approximately equal to the width of two cells, the front and back sides are each approximately equal to the width of three cells, a first terminal is provided proximate to a first corner of the battery, a second terminal is provided proximate to a second corner of the battery, and the first corner and second corner are both proximate to the same side of the battery.
10. The battery of claim 8 wherein approximately one half of the top side of the second, third, sixth, and fourth cells are covered by battery straps.
11. The battery of claim 8 wherein more than one half of the top side of the first and fifth cell is covered by battery straps.
12. The battery of claim 1 wherein the battery cells are cylindrical.
