摘要： Disclosed are a method and a device for detecting inconsistency of single cells in vehicle battery, and a medium. The method includes obtaining current battery data for a vehicle under test, determining whether the current battery data corresponds to a charging or discharging condition, and separately evaluating the presence of inconsistency in cells under each condition. This enables distinct detection for charging and discharging conditions, thereby enhancing detection accuracy.
