Abstract
A method and an apparatus for calculating the SOC of a battery being charged and a battery pack including the apparatus are disclosed in the present disclosure. The method for calculating the SOC includes: obtaining a full charge voltage and a reference charging voltage curve of the battery; taking a voltage value from the approximately linear ascent stage of the reference charging voltage curve as a preset reference voltage, and obtaining a corresponding reference SOC; acquiring a current charging voltage at which a charging voltage curve corresponding to a current charging state of the battery enters into an approximately linear ascent stage; determining a compensation factor according to the preset reference voltage, the full charge voltage, and the current charging voltage; and utilizing the compensation factor and the reference SOC to calculate a current SOC corresponding to the current charging state of the battery.
