Abstract

A portable information handling system battery pack couples plural flat battery cells to a frame in first and second planes having battery cells of the first plane aligned to extend past battery cells of the second plane in a cantilevered manner. In one embodiment, the battery pack integrates a battery management unit and a wireless charger.

First claim

What is claimed is:

1. An information handling system comprising:
a housing;
a processor disposed in the housing and operable to process information;
a memory disposed in the housing and interfaced with the processor, the memory operable to store information; and
a battery disposed in the housing, the battery having plural cells cooperatively interfaced to output a predetermined voltage, the plural cells having a flat rectangular shape, a first set of the plural cells coupled adjacent to each other end to end in a first plane, a second set of the plural cells stacked vertically in a second plane relative to the first plane and cantilevered to extend outward from each end of the first set of the plural cells.

2. The information handling system of claim 1 further comprising:
a frame disposed between the first and second planes, the frame holding the first set of battery cells adjacent to each other and supporting the second set of battery cells cantilevered to the first set of battery cells; and
a battery management unit integrated in the frame to coordinate charge and discharge of the battery cells as a battery pack.

3. The information handling system of claim 2 wherein each of the plural battery cells flat rectangular shape has a first set of parallel sides longer than a second set of parallel sides, the first set of plural cells having the first set of parallel sides perpendicular to the second set of plural cells first set of parallel sides.

4. The information handling system of claim 3 wherein:
the first set of battery cells includes four battery cells disposed in a row adjacent to each other; and
the second set of battery cells include a first battery cell at one end of the row having a corner cantilevered from the end of the row and second battery cell at an opposing end of the row having a corner cantilevered in a symmetric manner to the first battery cell.

5. The information handling system of claim 4 further comprising a wireless antenna disposed between the first and second battery cells of the second set of battery cells.

6. The information handling system of claim 4 wherein the housing and cantilevered battery cells define an acoustic chamber at each of opposing sides of the battery.

7. The information handling system of claim 4 further comprising a wireless charging device integrated in the battery between the first and second battery cells of the second set of battery cells.

8. The information handling system of claim 1 wherein the housing comprises a single planar piece containing the processor, memory and battery disposed under the display.

9. The information handling system of claim 1 wherein the housing comprises:
a lid housing portion integrating the display;
a main housing portion integrating the processor, memory and battery disposed under a keyboard; and
a hinge rotationally coupling the lid housing portion and main housing portion.

10. A method for assembly of an information handling system, the method comprising:
disposing processing components in a planar housing, the processing components configured to process information;
coupling a first set of flat battery cells to a first side of a battery frame in a first plane, the first set of flat battery cells coupled end to end in a single row;
coupling a second set of flat battery cells to a second side of the battery frame in a second plane, a first flat battery cell of the second set of flat battery cells aligned to extend past the first set of flat battery cells at a first end, a second flat battery cell of the second set of flat battery cells aligned to extend past the first set of flat battery cells at second end opposite the first end; and
disposing the flat battery cells in the planar housing.

11. The method of claim 10 wherein the first and second flat battery cells of the second set of flat battery cells each couple to the first set of flat battery cells to have first and second sides extend past the first set of flat battery cells in a cantilevered manner.

12. The method of claim 11 further comprising:
coupling a battery management unit to the battery frame; and
interfacing the flat battery cells and the battery management unit through the battery frame.

13. The method of claim 12 wherein the first set of flat battery cells are aligned perpendicular to the second set of flat battery cells.

14. The method of claim 11 further comprising:
integrating speakers in the planar housing; and
defining an acoustic chamber between ends of the cantilevered flat battery cells and the planar housing to enhance sound output by the speakers.

15. The method of claim 11 further comprising:
coupling a wireless charger to the frame between the first and second flat battery cells of the second set of flat battery cells; and
interfacing the wireless charger with the flat battery cells.

16. The method of claim 15 further comprising:
coupling a keyboard to planar housing in the second plane adjacent the second set of flat battery cells; and
supporting the keyboard with the first set of flat battery cells.

17. A battery comprising:
a frame having an upper surface and a lower surface;
a first set of plural flat battery cells coupled to the frame upper surface in a row;
a first flat battery cell coupled to the frame lower surface at a first end of the frame, the first flat battery cell having a rectangular shape with first and second perpendicular sides extending past the frame; and
a second flat battery cell coupled to the frame lower surface at a second end of the frame opposite the first end, the second flat battery cell having a rectangular shape with first and second perpendicular sides extending past the frame.

18. The battery of claim 17 wherein all of the first set of flat battery cells, the first flat battery cell and the second flat battery cell have substantially the same dimensions.

19. The battery of claim 18 wherein the first and second flat battery cells are oriented perpendicular to an orientation of the flat battery cells of the first set of flat battery cells.

20. The battery of claim 19 further comprising a wireless charger coupled to the frame between the first and second flat battery cells.
