Abstract: A battery cell includes an inner plastic layer, an outer plastic layer, and a middle metal layer. The inner and outer plastic layers extends along at least three of sides of the battery cell. The middle metal layer is disposed between the inner and outer plastic layers. The middle metal layer extends along the at least three sides of the battery cell and projects from at least a fourth side of the battery cell to form at least one heat dissipation tab. The at least one heat dissipation tab is configured to transfer heat to at least one cooling plate through thermal conduction. The fourth side of the battery cell connects two of the at least three sides to one another.

Abstract: An assembly includes a heat exchanger with an inlet portion. an outlet portion, and at least one fluid passage fluidly coupling the inlet portion to the outlet portion. The assembly additionally includes a movable blocker element having a first position with respect to the heat exchanger and a second position with respect to the heat exchanger. In the second position the blocker element reduces cross-sectional area of the at least one fluid passage relative to the first position. The assembly further includes a passive actuator coupled to the blocker element and configured to selectively move the blocker element from the first position to the second position in response to a thermal condition being satisfied.
