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.

Abstract: A method for adaptive battery charging and an apparatus therefor are disclosed. The present disclosure relates to a battery system for electronic devices and more particularly to the rate of charging of batteries in electronic devices. The method and apparatus are directed to dynamically determining the charging rate of a battery of an electronic device, based on factors such as user profile, usage, age of battery, etc. The method discloses determining at least one charging rate for a battery, determining at least one model representing an effect of degradation of the battery and a charging time for at least one charging mechanism, determining charging profiles over a cycle life of the battery based on the at least one model, and applying the charging profiles to the battery.

Abstract: Embodiments herein provide a method for real time adaptive charging of a battery. The method includes receiving at least one battery parameter. Further, the method includes determining a present battery condition. Further, the method includes correcting the at least one battery parameter based on the present battery condition. Further, the method includes determining a real time optimal current used for charging the battery based on the at least one corrected battery parameter. Further, the method includes charging the battery based on the determined real time optimal current, where a battery management system configures a charger integrated circuit to charge the battery. Further, the method includes updating and storing the at least one battery parameter in real time in a memory after charging the battery at the optimal current.
