Abstract: One general aspect includes a system having one or more heat pads installed at a vehicle, the one or more heat pads configured to provide infrared energy transmissions to a vehicle component to defrost, defog, or both defrost and defog a surface of the vehicle component. The system may also carry out the following steps: (a) determining that ice or fog or both ice and fog has accumulated on the surface of the vehicle component; and (b) based on the determination made in step (a), activating the one or more heat pads to defrost, defog, or both defrost and defog a surface of the vehicle component.

Abstract: A climate control device includes a radiant heater for radiating heat and a porous material attached to the radiant heater. The porous material desorbs a plurality of water molecules, in response to the porous material receiving heat from the radiant heater and raising a temperature of the water molecules in the porous material to a boiling temperature threshold. The porous material adsorbs the water molecules in response to the temperature of the water molecules falling below the boiling temperature threshold.

Abstract: Systems and methods are provided for radiant heating by PTC radiant patches. A radiant heating system for warming an occupant of an enclosed space includes patches to radiate heat into the enclosed space toward the occupant. A power supply supplies electric power to the patches. A controller controls the electric power supplied to the patches based on a temperature in the enclosed space and locations of the patches within the enclosed space.

Abstract: Disclosed herein is a battery module comprising a plurality of battery cells encased in an outer shell. The outer shell has disposed on an inner surface a flame retardant layer that comprises expandable graphite. The expandable graphite is operative to expand during an thermal event that results in an increase in battery module temperature. Disclosed herein too is a method comprising disposing in a battery module a flame retardant layer; where the battery module comprises a plurality of battery cells encased in an outer shell. The outer shell has disposed on an inner surface a flame retardant layer that comprises expandable graphite.
