Abstract
An electronic cigarette (“e-Cig”) may include improved charging of the battery. A more accurate battery voltage can be detected for the connectors with the chargers that can provide for an optimized evaluation of the charging process. Various battery properties may be detected based on resistance measurements from within the e-Cig. The battery charging can be controlled and optimized based on a slow control of the current and voltage.
Claims13
An electronic cigarette comprising:
- a battery portion that provides power to the electronic cigarette;
- a cartomizer coupled with the battery portion that generates a vapor;
- and
- one or more connectors for establishing an electrical connection, wherein a battery voltage is measured at the one or more connectors and the voltage is controlled based on this measurement.

A method of charging a battery in an electronic cigarette, said method comprising:
- charging the battery with a charging current, during a first charging stage, while periodically measuring the battery voltage based on a first time period, wherein the charging current remains constant during the first charging stage;
- determining whether the measured battery voltage is greater than a predetermined value;
- reducing the charging current by a predetermined amount, during a second charging stage, when the measured battery voltage is greater than the predetermined value, periodically measuring the battery voltage according to a second time period, and reducing the charging current by a predetermined amount when the measured battery voltage is greater than the predetermined value;
- and
- stopping the charging of the battery when the charging current is reduced to a predefined minimum current.
