  • Patent number: 9474027
    Abstract: A method of internally heating a power supply of an electronic device in reduced temperatures is provided. The method comprises positioning an antenna of the electronic device proximate to the power supply and receiving a “temperature” signal that is a function of a temperature of the power supply. When it is determined that the temperature is within a reduced operating-temperature range, the temperature is elevated and the equivalent series resistance (ESR) of the power supply is correspondingly reduced by actively sending current through the antenna. The “current sending” operation is reduced when the temperature of the portable electronic device is outside the reduced operating-temperature range.

  • Patent number: 9160833
    Abstract: Systems and methods are provided for downloading battery data to a mobile communication device. A system for downloading battery data to a mobile communication device may include a mobile communication device and a data server. The mobile communication device may be configured to monitor a battery operating condition and to receive a battery profile, the battery profile including battery data for use by the mobile communication device to calculate battery status information. The data server may be used for storing battery data, the data server being configured to receive the battery operating condition from the mobile communication device and, based on the battery operating condition, send the battery profile to the mobile communication device.

  • Patent number: 9146282
    Abstract: Systems and methods are disclosed for detecting whether a battery in an electronic device is counterfeit or defective. An actual battery characteristic profile is generated by recording the performance of the battery during use of the battery by the device. This profile is then compared to its corresponding expected characteristic profile. If the profiles are not substantially similar (i.e. if the error between the two curves exceeds a given error threshold), the battery is determined to be counterfeit or defective and responsive action is taken.

  • Patent number: 8852819
    Abstract: The disclosure is directed at a method and apparatus for controlling fuel cell operating characteristics. In certain situations, the operating efficiency of fuel cells is degraded to external conditions. Providing a method and apparatus to control operating conditions for the fuel cell assists in improving the operating efficiency. This can be achieved by controlling certain environmental conditions, such as temperature and relatively humidity, in the area surrounding the fuel cell.

  • Publication number: 20120194130
    Abstract: Systems and methods to detect a failure of a subset of component power packs within a multiple component rechargeable power pack. At least one parameter of a charging current that is provided for a time duration to a rechargeable power pack is determined. A measured capacity change quantity for the rechargeable power pack during the time duration is estimated. The measured capacity change quantity is compared, after the time duration, to an expected capacity change quantity that is based upon the at least one parameter. A determination is made that at least one component power pack within the rechargeable power pack has failed based on a difference between the measured capacity change quantity and the expected capacity change quantity. A charging current parameter is modified in response to the determining that the at least one component power pack has failed.
