摘要： This application discloses a charging duration determining method, a BMS, a battery, and an electrical device. The method includes: determining a charge temperature of a battery; estimating, in a case that the charge temperature exceeds a first specified range, a first duration to be taken to adjust the charge temperature of the battery to the first specified range; estimating a second duration to be taken to charge the battery to a target SOC after the charge temperature of the battery has been adjusted to the first specified range; and determining, based on a charge start time of the battery, the first duration, and the second duration, a duration to be taken to charge the battery to the target SOC. The charging duration determined for the battery according to this application is more accurate, and facilitates users to accurately learn the charging status of the battery in time.
