  • Battery management system and battery management method thereof
    Patent number: 12259440
    Abstract: Provided is a battery management system and method for selecting at least one battery cell of a high-risk group and calculating a maximum current limit value for stably using a battery pack using the selected at least one battery cell of the high-risk group. According to the present invention, the battery cells of high-risk group may be selected and managed by calculating a maximum voltage change amount of a plurality of battery cells, and the battery pack may be stably used by calculating a maximum current limit value that prevents the battery cell from being out of an operating voltage range to have a maximum margin.
    Type: Grant
    Filed: August 25, 2023
    Date of Patent: March 25, 2025
    Assignee: SK On Co., Ltd.
    Inventors: Kyung Chul Ko, Jeong Min Seo, Byung Eun Lee
