BATTERY DISCHARGE UNDERVOLTAGE PROTECTION METHOD, BATTERY APPARATUS, AND ELECTRIC APPARATUS

A battery discharge undervoltage protection method includes: acquiring a temperature and a first voltage of a battery; determining, based on the temperature, a depth of discharge of the battery; determining, based on the first voltage, a first remaining capacity proportion of the battery; and determining, based on the first remaining capacity proportion, the depth of discharge and a first undervoltage threshold, a second undervoltage threshold to increase a discharge capacity proportion of the battery, the first undervoltage threshold is a preset undervoltage threshold, and the second undervoltage threshold is a dynamically adjusted undervoltage threshold.
