Abstract: A battery pack includes a battery pack enclosure surrounded by an external environment and housing battery cells. The battery pack enclosure includes a tray having a first compartment housing the battery cells and a second compartment configured to collect high-temperature gas emitted by the battery cell(s) during a thermal runaway and expel the gas to the external environment. The battery pack enclosure also includes a cover configured to engage the tray and seal the enclosure. The first compartment is arranged between the second compartment and the cover. The battery pack also includes a temperature-sensitive component arranged inside the enclosure between the second compartment and the cover. The battery pack additionally includes a vent channel fluidly connecting the first and second compartments and configured to direct the high-temperature gas from the first compartment to the second compartment, thereby diverting the gas away from the temperature-sensitive component.

Abstract: A battery module includes a first battery cell and a neighboring second battery cell, and an insulating member positioned therebetween. The battery module also includes a battery module enclosure surrounded by an external environment and configured to house each of the first battery cell, the second battery cell, and the insulating member. The battery module additionally includes a battery module cover mounted to the battery module enclosure. The battery module cover includes a vent feature configured to expel high temperature gases from the first battery cell and divert the high temperature gases away from the second battery cell directly to the external environment. The cover is thereby configured to minimize transfer of the high temperature gases from the first battery cell to the second battery cell and control propagation of a thermal runaway event in the battery module.

Abstract: A mechanical design of a rechargeable battery cell (e.g., a Lithium-ion battery) disposed inside of a prismatic can, for use in electric vehicles and other electric-powered devices. The improved design uses a thermally conductive insert to divide the battery cell into two adjacent volumes that each hold a pair of stacked layers of a battery cell. This thermally conductive insert conducts heat from the center of the battery cell during battery recharging to actively-cooled channels disposed in a pair of cooling manifolds that are disposed on two vertical sides of the battery cell. Alternatively, or additionally, an actively-cooled bottom cold plate can be used. The pair of stacked battery layers can each be wound in a “jelly-roll” geometric configuration. The thermally conductive insert may be made of aluminum, aluminum alloy, copper, or copper alloy, and combinations thereof.

Abstract: Presented are battery assemblies with gas manifold liners and support tray seals for optimized gas venting, methods for making/using such battery assemblies, and vehicles equipped with such battery assemblies. A battery assembly, such as a rechargeable high-voltage traction battery pack, includes a support tray that seats thereon a cold plate. The cold plate is formed with a thermally conductive material and includes a gas manifold that exhausts gases from the battery assembly. At least one battery cell is supported on the cold plate and includes a cell case that contains a galvanic electrochemical cell and has a cell vent fluidly coupled with the gas manifold. A manifold liner is located within and abuts opposing walls of the gas manifold. The manifold insert includes one or more thermal barrier layers, each formed with a thermally insulating material, and one or more electrical barrier layers, each formed with an electrically insulating material.

Abstract: A dual-function, combined thermal/structural structure for simultaneously holding and cooling one or more battery cells that are stacked inside of a battery pack. The dual-function structure comprises: (1) a first cooling plate with a first plurality of parallel internal coolant channels; (2) a second cooling plate with a second plurality of parallel internal coolant channels; (3) a first structural side plate; (4) a second structural side plate; and (5) fasteners for joining the first cooling plate, the second cooling plate, the first structural side plate, and the second structural side plate together into an rectangular, box-like, cooled structure. The first and second cooling plates simultaneously structurally support and thermally cool one or more battery cells on at least two opposite sides. Additional horizontal cooling plates can be used to thermally cool and structurally support the underside of each battery cell, thereby providing a 3-sided cooling effect.
