Abstract
A method, an information handling system, and a thermal management system providing a power and thermal solution are provided. In accordance with at least one embodiment, the information handling system includes a battery having a low temperature cell configured to operate over a lower temperature range and a high temperature cell configured to operate over a higher temperature range, a computational electronic circuit operable to dissipate waste heat as a consequence of performing computation, and a thermal conductor thermally coupled to the high temperature cell and to the computational electronic circuit but not to the low temperature cell.

A method comprising:
- detecting a temperature of a battery array including a low temperature cell configured to operate over a lower temperature range and a high temperature cell configured to operate over a higher temperature range;
- determining if the battery array temperature is below a cold threshold;
- when the battery array temperature is below the cold threshold, powering an information handling system from the low temperature cell;
- determining if the battery array temperature is above a hot threshold;
- when the battery array temperature is above the hot threshold, reducing power dissipated by the information handling system;
- when the battery array temperature is above the cold threshold and below the hot threshold, powering the information handling system from the high temperature cell;
- transferring heat from a computational electronic circuit of the information handling system to a heat spreader overlying the high temperature cell at an exterior surface of the information handling system but not overlying the low temperature cell at the exterior surface;
- and
- transferring heat from the computational electronic circuit of the information handling system to the high temperature cell.
