Abstract: A rotor for an electric machine includes a heat pipe cooling system. A rotor core has a number of cavities internal to the rotor core. The cavities are surrounded by a wall defined by the rotor core. A magnetic element disposed in the at least one cavity leaving a void in the at least one cavity between the magnetic element and the wall. A heat pipe evaporator is disposed in the void and conforms to the available space, contacting the magnetic element and the wall to remove heat from the rotor core.

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. The expandable graphite is operative to expand during an thermal event that results in an increase in battery module temperature.

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: A battery cell thermal conditioning system for a vehicle includes a battery pack having multiple battery cells. Multiple foam layers are individually positioned between first successive ones of the battery cells. A first carbon nanotube sheet is positioned in direct contact with one of the battery cells on a first side of the foam layers and a second carbon nanotube sheet is positioned in direct contact with a different one of the battery cells on a second side of the foam layers. A cooling plate is positioned between second successive ones of the battery cells. A controller directs current flow to the first carbon nanotube sheet and the second carbon nanotube sheet when a temperature of the one of the battery cells contacted by the carbon nanotube sheet drops below a predetermined threshold temperature.
