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: 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 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: Various embodiments disclosed herein relate to systems and methods for battery cell ventilation. A corrugated battery module lid may be integrated above a battery cell module, wherein the corrugated lid includes a plurality of crests and troughs to form one or more gas emission channels. The plurality of crests and troughs may be at least partially positioned to encompass at least one of the plurality of battery cells to form enclosures. The enclosures may accumulate a maximum amount of gas pressure from a gas emitted by the at least one of the plurality of battery cells. One or more pressure release mechanisms may be associated with the plurality of enclosures and integrated with the battery module lid. In response to the enclosure exceeding the maximum amount of gas pressure, the gas may be automatically released through the pressure release mechanisms and flow though the channels between the crests.
