Heat control in battery pack stack
One embodiment provides an electronic device, including: a battery pack stack comprising at least two battery packs; wherein the battery pack stack comprises at least one cumulative heat reducing component positioned between the at least two battery packs. Other aspects are described and claimed.
1. An electronic device, comprising:
a battery pack stack comprising at least two battery packs;
wherein the battery pack stack comprises at least one cumulative heat reducing component positioned between the at least two battery packs, wherein the at least one cumulative heat reducing component comprises a heat insulating film located between a first and second heat spreader, wherein the first heat spreader touches one of the at least two battery packs and wherein the second heat spreader touches an adjacent second of the at least two battery packs.
2. The electronic device of claim 1 , wherein the at least one cumulative heat reducing component is positioned between each of the at least two battery packs.
3. The electronic device of claim 1 , wherein the battery pack stack is one of: a horizontal stack or a vertical stack.
4. The electronic device of claim 1 , wherein the at least one cumulative heat reducing component further comprises a heat conductive film.
5. The electronic device of claim 4 , wherein the heat conductive film is an adhesive.
6. The electronic device of claim 4 , wherein the heat conductive film substantially eliminates cumulative heat between the at least two battery packs.
7. The electronic device of claim 1 , wherein each of the two heat spreaders wrap at least partially around a corresponding inner surface of one of the at least two battery packs.
8. The electronic device of claim 1 , wherein the at least one cumulative heat reducing component further comprises a phase change film.
9. The electronic device of claim 8 , wherein the phase change film is composed of a wax material.
10. A battery pack stack, comprising:
at least two battery packs;
at least one cumulative heat reducing component positioned between the at least two battery packs, wherein the at least one cumulative heat reducing component comprises a heat insulating film located between a first and second heat spreader, wherein the first heat spreader touches one of the at least two battery packs and wherein the second heat spreader touches an adjacent second of the at least two battery packs.
11. The battery pack stack of claim 10 , wherein the at least one cumulative heat reducing component is positioned between each of the at least two battery packs.
12. The battery pack stack of claim 10 , wherein the battery pack stack is one of: a horizontal stack or a vertical stack.
13. The battery pack stack of claim 10 , wherein the at least one cumulative heat reducing component further comprises a heat conductive film.
14. The battery pack stack of claim 13 , wherein the heat conductive film is an adhesive.
15. The battery pack stack of claim 10 , wherein each of the two heat spreaders wrap at least partially around a corresponding inner surface of one of the at least two battery packs.
16. The battery pack stack of claim 10 , wherein the at least one cumulative heat reducing component further comprises a phase change film.
17. The battery pack stack of claim 16 , wherein the phase change film is composed of a wax material.
