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.
Claims14
A method comprising:
- providing a battery cell;
- providing a thermally insulating layer;
- providing a thermally conducting layer having a surface in physical contact with the battery cell;
- determining a desired capacitance for the thermally conducting layer;
- determining a placement of at least one discontinuity based on the desired capacitance;
- forming the at least one discontinuity on the surface of the thermally conducting layer in physical contact with the battery cell based on the desired capacitance, wherein the at least one discontinuity is configured to reduce an individual capacitance associated with the thermally conducting layer to the desired capacitance;
- and
- stacking at least the battery cell, the thermally insulating layer and the thermally conducting layer including the at least one discontinuity into a battery submodule.
