Abstract: A battery pack is disclosed and includes battery cells, an outer housing, a support structure, and a planar structure. The outer housing is configured to enclose and immerse the plurality of battery cells in a coolant. The outer housing includes multiple walls including side walls, a top wall and a bottom wall. The support structure supports the battery cells. The support structure includes dividing members separating the battery cells. The planar structure is disposed above or below the battery cells. A gap exists between a planar surface of the planar structure and a planar surface of one of the top wall and the bottom wall of the outer housing for flowing the coolant between the planar structure and the one of the top wall and the bottom wall. The planar structure and at least some of the walls direct the coolant to flow across and between the battery cells.

Abstract: A cooling assembly according to various aspects of the present disclosure includes a housing, an electronic component, a dielectric coolant, and a cover. The housing includes an interior compartment having a basin region in which the electronic component and the coolant are disposed. The coolant undergoes phase change between a liquid state and a gas state. The coolant is in direct contact with the electronic component in the liquid state. The cover component extends transversely through the interior compartment and is coupled to the body. The cover component is disposed in a direction with respect to the basin region. The cover component at least partially defines a port in fluid communication with the basin region. The cover component is configured to permit flow therethrough of the dielectric coolant in the gas state in at least the direction.

Abstract: A cooling system includes a housing configured to enclose an electric vehicle component immersed in cooling fluid and to define a first volume. A variable volume member defines a second volume that varies in response to a first signal. A combined volume is defined by the first volume and the second volume. Heat causes the cooling fluid to transition between a liquid state and a vapor state in the combined volume. A pressure sensor is configured to sense a pressure in the combined volume. A condenser is configured to cause the cooling fluid to transition from the vapor state back to the liquid state. A controller includes a volume adjustment module configured to generate the first signal to vary the second volume of the variable volume member to adjust the combined volume in response to the pressure and a first temperature of the electric vehicle component.
