Abstract
An electrically heating smoking system wherein tobacco smoke is generated by heating a portion of a cigarette with an electrical resistance heating element powered by lithium ion battery cells. The lithium ion battery cells supply current to the electrical resistance heating element with current up to 20 times greater than the recommended discharge rate. To prevent damage to the lithium ion battery cells under such high discharge conditions, the smoking system includes a controller which provides modulated pulses of electrical power from the battery cells to the resistance heating element during smoking of the cigarette.
