Abstract: A redundant, load-sharing system and method for distributing electrical power to components in a vehicle. The system including a source of power, multiple power distribution buses, a plurality of switching devices and at least two channel controllers. The system being configured to isolate the components and power sources that are determined to be electrically noisy from the components and the power sources that are sensitive to electric noise. Each of the components may be assigned a priority based on the criticality of the component to the operation of the vehicle. In the event of at least a partial loss of power in one or more of the power distribution buses, the switching devices disconnect the components from the effected power distribution buses in reverse order of the assigned priority.

Abstract: A thermal management system and method for regulating the dissipation of a thermal load during operation of a vehicle. The thermal management system including one or more cooling loops configured to regulate the temperature of at least one battery pack; and an energy recovery mechanism configured to recover energy dissipated upon the occurrence of a thermal runaway event. The amount of energy recovered maintains the power level at or above the level exhibited by the battery pack prior to the occurrence of the thermal runaway event. Upon the occurrence of the thermal runaway event, the energy recovery mechanism transforms the cooling loop into a Rankine cycle loop or uses a Seebeck effect to recover energy.
