    摘要： There are provided a battery management apparatus, a battery management method and a battery pack. The battery management apparatus includes a sensing unit configured to detect a current, a voltage and a temperature of a battery, and a control unit. The control unit determines a first candidate value for a state of charge (SOC) of the battery using ampere counting. The control unit determines a Kalman gain and a second candidate value for the SOC using an extended Kalman filter. The control unit determines the first candidate value as the SOC when a difference value between the first candidate value and the second candidate value is larger than a threshold value. The control unit adjusts a ratio of second process noise to first process noise in the extended Kalman filter based on a first component and a second component of the Kalman gain.

    摘要： The present application provides a method and apparatus for correcting a state of charge, and relates to the technical field of batteries. The method for correcting a state of charge comprises: determining an operating state of a battery cell, wherein the operating state comprises a discharging state or a charging state; and determining a corrected state of charge of the battery cell according to an acquired current open circuit voltage of the battery cell, an acquired current accumulative capacity of the battery cell, an accumulative capacity correspondence relationship corresponding to the operating state of the battery cell, and an open circuit voltage curve corresponding to a limit initial state of charge, wherein the accumulative capacity correspondence relationship comprises a correspondence relationship between a pre-measured open circuit voltage and an accumulative capacity threshold. A technical solution of the present application can be used to improve the accuracy of calculation of a state of charge.
