摘要： The present disclosure provides a method and a system for improving the state of health (SoH) of rechargeable batteries. The method comprises receiving a plurality of battery parameters during charging of a battery and estimating model parameters of the battery using a mathematical model. The method also comprises comparing the estimated model parameters of the battery and the received battery parameters to determine degradation parameters of the battery in real-time, determining new charging current profile of the battery based on the degradation parameters of the battery, and applying the determined new charging current profile to the battery for improving the SoH of the battery.

摘要： An electronic device including a battery pack and an operation method of the electronic device is provided. The electronic device includes a system circuitry and a battery pack, wherein the battery pack includes a battery management circuitry, a protection operation circuitry, and a battery, wherein the battery management circuitry may be configured to identify a state of the battery to obtain battery state information, activate, on the basis of the battery state information, a ship mode for minimizing power consumption of the battery, and control the protection operation circuitry to electrically disconnect the system circuitry from the battery pack, inactivate the ship mode on the basis of connection between a power key included in the system circuitry and a first pin of the battery management circuitry, and control the protection operation circuitry to electrically connect the system circuitry to the battery pack.

摘要： 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.
