Electrically heated smoking system and methods for supplying electrical power from a lithium ion power source
First Claim
1. An electrically heated smoking system comprising:
- at least one electrical resistance heating element;
a lithium ion power source electrically connected to the at least one electrical resistance heating element; and
a controller to control a flow of modulated pulses of electrical power from the lithium ion power source to the at least one electrical resistance heating element to prevent damage to the lithium ion power source.

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.

17. A method for smoking a cigarette with an electrically heated smoking system, the method comprising:
-
providing electrical power to at least one electrical heating element from a lithium ion power source, the at least one electrical heating element being arranged to heat at least a portion of a cigarette sufficiently to generate tobacco smoke; and
controlling the electrical power provided to the at least one electrical heating element by sending modulated pulses of electrical power from the lithium ion power source to the at least one electrical heating element thereby preventing damage to the lithium ion power source. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
