Abstract: A battery module includes a plurality of electrochemical cells arranged in a first row and a second row offset from the first row. The battery module also includes a heat exchanger configured to allow a fluid to flow through the heat exchanger. The heat exchanger is disposed between the first and second rows of cells and has a shape that is complementary to the cells in the first and second rows of cells so that an external surface of the heat exchanger contacts a portion of each of the plurality of electrochemical cells. The heat exchanger is configured to route the fluid between an inlet and an outlet such that a path of the fluid flow includes a plurality of adjacent fluid flow segments.

Abstract: Battery systems and modules having external thermal management systems are provided. In one embodiment, a battery module includes a housing and at least one electrochemical cell disposed within the housing. The battery module also includes a thermal interface having a first side in contact with the at least one electrochemical cell. The battery module also includes a heat sink in contact with a second side of the thermal interface. The thermal interface is adapted to enable heat transfer from the at least one electrochemical cell to the heat sink.

Abstract: Provided herein are electrochemical cells having improved heat collection and transfer systems. For example, one electrochemical cell includes a drawn can having a blind side and a second side opposite the blind side. The cell also includes a positive terminal disposed in the blind side of the can and electrically coupled to at least one positive electrode disposed within the can and a negative terminal disposed in the blind side of the can and electrically coupled to at least one negative electrode disposed within the can. The cell further includes a base coupled to a substantially flat edge disposed on the second side of the can. A bottom surface of the base is adapted to maintain a substantially flat configuration when coupled to a heat sink.

Abstract: A battery module includes a plurality of electrochemical cells and a structure including an upper portion configured to support a bottom portion of each of the plurality of electrochemical cells and a lower portion coupled to the upper portion. The lower portion includes a thermal management feature having at least one passage provided therein.

Abstract: A battery module includes a plurality of electrochemical cells provided side-by-side one another and a thermal management feature extending substantially the length of the battery module. The thermal management feature is coupled to a first side of each of the electrochemical cells and includes a passage though which a thermal management fluid may pass and a heat sink provided within the passage to transfer heat between the electrochemical cells and the thermal management fluid.
