Abstract: Thermal management systems for batteries utilize vapor chambers having wicking components therein. An exemplary thermal management system includes a vapor chamber containing a working fluid and wicking components. A plurality of battery cells are disposed at least partially in the vapor chamber. A cold plate is coupled to the vapor chamber, and a heat pump is coupled to the cold plate. A capillary tube may be utilized to facilitate movement of vapor and working fluid in the thermal management system. Via use of exemplary systems, improved thermal management for batteries is provided.

Abstract: A cold plate for a battery may comprise channels that extend from a first end of the plate to a second end of the plate or from a first side of the plate to a second side of the plate, the channels are located in parallel with each other and between the top surface and the bottom surface. The channels may be separated from each other by walls. The plate may be milled to form a first manifold on each end. The plate may also be milled to form notches in the surface(s) over the manifold. A port for the inlet and a port for the outlet of a working fluid may be inserted into the notches. The plate may have end caps, and the end caps and the ports may be welded or brazed to form a sealed enclosure. In various embodiment, the plate is an extruded plate, a cast plate, or a stamped/formed plate.

Abstract: A battery cell is made more thermally efficient with the addition of an integrated vapor chamber that extends out from the cell and into an external heat exchange interface. The integrated vapor chamber can contain a working fluid which undergoes phase changes between liquid and vapor phases when there is a temperature differential between the interior and exterior of the cell. The integrated vapor chamber can include a wicking material to transfer the working fluid to the exterior wall of the vapor chamber. The integrated vapor chamber allows for both heating and cooling of the battery cell.
