Abstract
A battery system includes a battery cell, a thermally insulating layer, and a thermally conducting layer which includes a fin. The fin pushes against an interior surface of a case which surrounds the battery cell, the thermally insulating layer, and the thermally conducting layer. The thermally conducting layer includes a discontinuity where the discontinuity is configured to reduce a capacitance associated with the thermally conducting layer compared to when the thermally conducting layer does not include the discontinuity.
Claims21
(canceled)
A system, comprising:
- a battery cell;
- a thermally insulating layer;
- and
- a thermally conducting layer which includes at least one discontinuity, wherein:
- the at least one discontinuity is formed on a predetermined location on a surface of the thermally conducting layer in physical contact with the battery cell based on a desired capacitance of the thermally conducting layer, and
- the at least one discontinuity is configured to reduce an individual capacitance of the thermally conducting layer to the desired capacitance.
3 more elements
A system, comprising:
- a plurality of battery submodules, wherein each battery submodule includes at least one battery cell, one thermally insulating layer, and one thermally conducting layer which includes at least one discontinuity formed on a predetermined location on a surface of the thermally conducting layer in physical contact with the battery cell based on a desired capacitance of the thermally conducting layer, wherein the at least one discontinuity is configured to reduce an individual capacitance of the thermally conducting layer to the desired capacitance;
- and
- a frame having a plurality of slots, each for receiving one of the plurality of battery submodules.
