Abstract: A vent for an electric vehicle battery pack configured to transition from a venting, open position to a sealed, closed position in the event of a thermal event experienced by the electric vehicle battery pack, thereby trapping the gasses within the electric vehicle battery pack, including a curved disc shaped and sized to selectively seal an aperture defined by the electric vehicle battery pack, the curved disc formed of a first material on a first major surface of the disc, and a second material positioned on an opposing second major surface of the disc, 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 curved disc causes the first material to expand more than the second material, thereby transitioning the curved disc from a first equilibrium state to a second equilibrium state.

Abstract: A vehicle rocker panel torsion lever configured to reduce intrusion in the event of a side impact, the vehicle rocker panel torsion lever including a rigid elongated member including a first end and a second end, the first end configured to be fixedly coupled to a rocker panel of a vehicle, the second end free-floating within a cavity defined by a B-pillar of the vehicle, the rigid elongated member configured to translate a linear external side-impact applied to the B-pillar to a rotational force applied to the rocker panel.

Abstract: A system as described herein can be used to maintain safety features for an electric vehicle. These features include redundant low-voltage power provision and redundant cooling, each provided by use of multiple battery strings.

Abstract: The disclosure relates to a drive shaft arrangement for an all-wheel drive electric vehicle, comprising a drive shaft arranged to transfer torque a drive shaft joint at least partially enclosing a drive shaft end portion, wherein the drive shaft joint comprises a housing and a one-way clutch provided at an inner portion of said housing. The one-way clutch being arranged within said inner portion to engage with said drive shaft at a first drive shaft state, in which the drive shaft transfers torque from said drive shaft in a first direction; disengage from said drive shaft at a second drive shaft state, in which the drive shaft is idle or transfers torque in a second direction opposite to the first direction. The disclosure also relates to a vehicle comprising said drive shaft arrangement.

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, including a vehicle structure, four ground engaging wheels, and a suspension system operably coupling each of the four ground engaging wheels with the vehicle structure, a battery operably coupled to the vehicle structure, and an onboard battery charger in electrical communication with the battery, the onboard battery charger operably coupled to the vehicle structure by a battery charger suspension system, the battery charger suspension system including one or more dampers tuned to counteract resonance vibrations experienced by the vehicle structure.
