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.
Claims9
An electronic vaping device having internal circuitry, comprising:
- a first battery portion including a battery and configured to provide power to the electronic vaping device;
- internal circuitry, the internal circuitry being operationally connectable to the battery to assist in charging the battery;
- a pair of connectors on an exterior end of the electronic vaping device configured to establish an electrical connection with an external device;
- a diode in a bypass line, the bypass line being electrically connected to one of the pair of connectors and a terminal of the battery, the bypass line bypassing the internal circuitry;
- and
- a controller configured to
- measure a first measured voltage at the pair of connectors during an application of a first current, the first current being high enough that the first current is capable of passing through the diode and being low enough that the first current is not capable of activating the internal circuitry, and
- determine a voltage of the battery based on the first measured voltage.
