Publication number: 20130300343Abstract: An electronic device may include a first charging port. A peripheral device connected to the first charging port can be sensed. The first charging port can be electrically connected to a battery charger of the electronic device by a first connection and configured to provide a charge to the battery charger through the first connection. The first charging port can be further electrically connected to a battery of the electronic device by a second connection and configured to receive a charge from the battery by the second connection. A charge (i.e., power) can be provided to the peripheral device from the battery through the second connection. A charge on the first connection can be directed away from the battery charger.Type: ApplicationFiled: May 9, 2012Publication date: November 14, 2013Inventors: Jace William Files, Mallikarjun Boda

Publication number: 20100213890Abstract: A method and system for detecting the use of an unauthorized battery pack in a portable electronic device. The method comprises monitoring a temperature profile of at least one battery cell in a battery pack during an operation of the portable electronic device. The temperature profile is determined in accordance with an output of an internal temperature sensing circuit in the battery pack. If the temperature profile is determined to be atypical, an indication is provided that the battery pack is an unauthorized battery pack. For example, if the temperature profile does not show an expected temperature rise during a charging operation, a visual indication can be provided. The indication can also trigger the control of charging or discharging operations of the portable electronic device. Charging can be terminated or the device shut down to avoid a potentially catastrophic thermal runaway event. The device can also be operated in a reduced power mode in response to the indication.Type: ApplicationFiled: February 25, 2009Publication date: August 26, 2010Applicant: Research In Motion LimitedInventors: Lyall Kenneth WINGER, Mallikarjun BODA, Jonathan Quinn BRUBACHER
