  • Patent number: 10424959
    Abstract: An electronic apparatus for charging a battery with an optimum charge profile corresponding to a pattern of use and a state of the battery is provided. The electronic apparatus may include a power supply configured to supply power to respective components of the electronic apparatus using power of a battery, and when receiving an input of power from an external adaptor, to charge the battery using the inputted power, and a processor configured to fully charge and discharge the battery to thus generate a charge curve and a discharge curve expressed in time and charge amount, and control the power supply to charge the battery using a charge profile corresponding to the generated charge curve and discharge curve.

  • Patent number: 10324139
    Abstract: Embodiments herein provide a method and electronic device for detecting an internal short circuit in a battery. The method includes obtaining, by a battery management system, battery gauge data. Further, the method includes estimating, by the battery management system, an internal resistance of the battery using the battery gauge data. Furthermore, the method includes detecting, by the battery management system, the internal short circuit in the battery by comparing a change in the internal resistance with a pre-defined resistance change threshold value.
