Abstract

A battery array according to an exemplary aspect of the present disclosure includes, among other things, a circuit connector assembly and a cover that partially covers the circuit connector assembly. The cover includes a groove. A sense-line wire is received within the groove.

Claims

1. A battery array, comprising:

a circuit connector assembly including a circuit board, a bus bar, a sensor, and a sense-line wire;

a cover that at least partially covers said circuit connector assembly, said cover including a first groove and a secondary groove;

said sense-line wire received within said first groove,

a wiring branch of said sense-line wire received within said secondary groove and extending from said sensor to said sense-line wire.

2. The battery array as recited in claim 1, wherein said cover includes an external face, said first groove extending longitudinally across said external face.

3. The battery array as recited in claim 1, wherein said first groove is positioned at a first distance from an end wall of said cover and a battery terminal of said battery array is positioned at a second distance from said end wall.

4. The battery array as recited in claim 3, wherein said first distance is a greater distance than said second distance.

5. The battery array as recited in claim 3, wherein said first distance is a smaller distance than said second distance.

6. The battery array as recited in claim 1, wherein said first groove is positioned at a first distance from an end wall of said cover, said first distance disposed between a second distance of a first battery terminal from said end wall and a third distance of a second battery terminal from said end wall.

7. The battery array as recited in claim 1, wherein said first groove is positioned between said bus bar and said sensor of said circuit connector assembly.

8. The battery array as recited in claim 1, wherein said secondary groove is connected to said first groove.

9. The battery array as recited in claim 8, wherein said secondary groove is perpendicular to said first groove.

10. The battery array as recited in claim 1, wherein said sensor is a voltage sensor.

11. The battery array as recited in claim 1, wherein said sense-line wire connects to a control module.

12. The battery array as recited in claim 1, wherein said cover establishes a side wall of said battery array or is directly attached to said side wall of said battery array.

13. The battery array as recited in claim 1, wherein said circuit board includes a first opening for accommodating a battery cell terminal and a second opening for accommodating a sensor.

14. A battery array, comprising:

a battery cell including a terminal;

a bus bar connected to said terminal;

an integrated circuit board cover at least partially covering said bus bar, said integrated circuit board cover including a groove formed on an external face of said integrated circuit board cover; and

sense-line wiring retained within said groove.

15. The battery array as recited in claim 14, wherein said integrated circuit board cover is positioned on a side of said battery cell.

16. The battery array as recited in claim 14, wherein said integrated circuit board cover is positioned over top of said battery cell.

17. The battery array as recited in claim 14, wherein said groove extends longitudinally across said external face of said integrated circuit board cover.

18. The battery array as recited in claim 14, wherein said integrated circuit board cover is positioned entirely on a single side of said battery cell.

19. A battery array, comprising:

a battery cell including a terminal;

a bus bar connected to said terminal;

an integrated circuit board electrically connected to said bus bar;
