Abstract: A system for managing dehumidification in a battery pack having a plurality of battery modules includes a casing is adapted to house the plurality of battery modules. The casing has at least one cavity with a dehumidification unit being at least partially positioned within the cavity. The dehumidification unit includes a desiccant. A heating element is positioned in proximity to and adapted to selectively heat the desiccant. The system includes a control unit having a processor and tangible, non-transitory memory on which instructions are recorded. The control unit is adapted to control the heating element. The desiccant is adapted to collect moisture during a collection phase of dehumidification and the heating element is adapted to dry the desiccant during a reconditioning phase of the dehumidification.

Abstract: An energy storage assembly includes a plurality of battery cells electrically connected to each other to form a battery pack in which the battery cells are grouped together to form a first stack of cells and a second stack of cells. The energy storage assembly also includes a first barrier disposed between the first stack of cells and the second stack of cells to reduce heat transfer between the first stack of cells and the second stack of cells. The energy storage assembly further includes a coolant plate disposed along the battery cells. The coolant plate defines a channel for guiding a fluid therethrough to thermally transfer heat away from the battery cells. The coolant plate defines a slot spaced from the channel, and the slot axially aligns with the first barrier to reduce heat transfer between the first stack of cells and the second stack of cells.
