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: A method of regulating thermal comfort of an occupant of a vehicle cabin uses a radiant heating tile powered via an energy storage device to generate thermal energy. The method also includes detecting the occupant's position via a position sensor and detecting the occupant's surface temperature and detecting a temperature of the tile via at least one temperature sensor. The method additionally includes determining, via an electronic controller, a rate of change of occupant's surface temperature and a difference between the tile temperature and the occupant's surface temperature relative to a predetermined temperature set-point. The method further includes regulating, via the electronic controller, a power input from the energy storage device to the tile in response to the determined rate of change of the surface temperature and the determined difference between the tile temperature and the occupant's surface temperature to thereby regulate the occupant's surface temperature.

Abstract: An adaptive radiant heating system regulates a climate inside a motor vehicle cabin having a seat for a vehicle occupant. The system includes radiant heating tiles arranged proximate the seat and powered by an energy storage device. The system also includes a first sensor for detecting a position of the occupant and generating a first signal indicative thereof. The system additionally includes a second sensor for detecting a temperature within the cabin and generating a second signal indicative thereof. The system furthermore includes an electronic controller in operative communication with the tiles and the first and second sensors, and configured to regulate the climate proximate the seat via selective control of the tiles. The controller is configured to receive the first and second signals and activate at least one of the tiles in response to the first and second signals, to thereby regulate the climate proximate the seat.
