Abstract: An electric vehicle battery pack configured to rapidly discharge one or more individual battery cells within a multi-cell battery arrangement to mitigate a propagation of a multi-cell thermal runaway event, the vehicle battery pack including a plurality of battery cells and a battery management system including sensing circuitry configured to sense one or more conditions of the plurality of battery cells, a processor configured to process data sensed by the sensing circuitry to determine whether any of the plurality of battery cells is experiencing the onset of a thermal runaway event, and a control engine configured to isolate and rapidly discharge a potential energy from a battery cell experiencing the onset of a thermal runaway event, thereby mitigating a potential for a propagation of a thermal runaway event experienced by a single cell into a multi-cell thermal runaway event.

Abstract: An emergency rapid cooling system configured to provide rapid cooling to an electric vehicle battery pack during a thermal event. The emergency rapid cooling system including at least one capsule filled with a fluid, the at least one capsule including at least one nozzle positioned in proximity to at least one battery cell, wherein the at least one nozzle is configured to open upon reaching at least one of a determined temperature or pressure, thereby enabling the fluid within the at least one capsule to rapidly decrease in pressure and accompanying temperature to provide cooling to the at least one battery cell.

Abstract: A charge port cover, sized and shaped for selective concealment of a charge port recess of a vehicle during vehicle connection via a charging cable to an external charging source. The charge port cover includes a body plate member comprised of rigid or semi-rigid material. The body plate member includes a planar front face and a planar rear face juxtaposed in opposite orientations to one another. The body plate member also includes an outer edge surface joining and defining a perimeter of the front face and the rear face, the outer edge surface having a thin profile. The body plate member also includes a charging connector aperture, located at an interior spaced-apart location from the perimeter, defining a passageway between the planar front face and the planar rear face and configured to selectively receive a charging cable therethrough.
