Abstract: An electric vehicle battery disconnect bracket configured disconnect one or more battery cells or modules experiencing a thermal event within a battery pack to mitigate propagation of the thermal event throughout the battery pack, including a bracket body formed of a first material on a first major surface of the body, and a second material on an opposing second major surface of the body, the first material having a larger coefficient of thermal expansion than the second material, such that an increase in temperature above a defined threshold experienced by the body causes the first material to expand more than the second material, thereby transitioning the body from a first equilibrium state representing a closed, conductive position to a second equilibrium state representing an open, isolation position.
Abstract: Active tire orientation and pressure adjustment systems and methods of use in response to a plurality of activation conditions can ensure efficient tire orientation and pressure modes are active when necessary to balance tire traction and driving range of an electric vehicle. The activation conditions can be customized based on driver preferences to help ease range anxiety while providing a balance with vehicle traction.
Abstract: Systems and methods of thermal control in a resilient battery cooling system ensure that power is maintained to operate a cooler even when an event disables a battery cell. The cooler can therefore prevent thermal propagation from the affected cell to neighboring cells.

Abstract: An electric vehicle battery pack release system configured to cause a physical separation of a battery pack from an electric vehicle on to which the battery pack is mounted, including one or more pyrotechnic bracket assembly configured to operably couple a battery pack to an electric vehicle, one or more sensor configured to sense a state of the electric vehicle, and an electronic control unit configured to receive data from the one or more sensors and to trigger an explosion in the one or more pyrotechnic bracket assemblies to affect the physical separation of the battery pack from the electric vehicle.
Abstract: The present disclosure relates to a stator for an electric motor of an electric vehicle, the stator comprising an annular stator core comprising an inner circumferential surface having circumferentially distributed slots formed in the inner circumferential surface. Further, comprising a hairpin winding arrangement comprising a plurality of hollow hairpin conductors, each hollow hairpin conductor. Each slot accommodates portions of a plurality of hollow hairpin conductors, the plurality of slots comprising fluid inlet slots and fluid outlet slots, wherein the fluid inlet slots accommodates a plurality of first portions and the fluid outlet slots accommodates a plurality of second portions such that each hairpin is accommodated by two slots. Furthermore, each inlet of each hollow hairpin conductor is arranged to receive cooling medium from a cooling device.
Abstract: A low-profile, selectively extendable cupholder located within an interior of a motor vehicle configured to transition between a collapsed position substantially maintaining a neat, clean appearance of the interior of the motor vehicle, and an extended position configured to receive a beverage container, the cupholder including a body portion defining one or more recesses, a lid portion configured to both pivot or slide relative to the body portion between an closed position and an open position, and one or more floor portions operably coupled to both the body portion and a lid portion and configured to both pivot and telescopically extend relative to the body portion between a collapsed position and an extended position, wherein in the extended position the body portion, the lid portion and the one or more floor portions collectively define a cavity configured to receive a beverage container.
