  "textContent": "Embodiments of this application relate to the technical field of batteries, and in particular, to a state-of-charge cut-off method, apparatus and control system, and a storage medium. The method includes: obtaining, in a discharging process of a battery, a net discharge capacity of a first battery cell from being fully charged to current time; obtaining an available capacity of the first battery cell and a state of health SOH of the first battery cell; obtaining a current remaining dischargeable capacity of the first battery cell, based on a nominal capacity of the battery, the net discharge capacity of the first battery cell, the available capacity of the first battery cell, and the SOH of the first battery cell; and setting a state of charge SOC of the first battery cell to 0 when a sum of the current remaining dischargeable capacity of the first battery cell and the net discharge capacity of the first battery cell is greater than or equal to the nominal capacity of the battery and the net discharge capacity of the first battery cell is equal to the nominal capacity of the battery. The method according to the embodiments of this application can accurately estimate a state of charge SOC of a battery including at least two different types of battery cells, reducing a probability that an electric apparatus shuts down before the SOC becomes 0.",
