Abstract: The present application relates to a method and an apparatus for controlling a temperature of a battery pack, a battery management system, and a storage medium. The method for controlling a temperature of a battery pack includes: detecting a SOC of the battery pack; determining a SOC interval in which the SOC is located from a plurality of preset SOC intervals; determining a target temperature threshold corresponding to the SOC interval under a condition that a preset battery pack life requirement is met, based on a mapping relationship between preset SOC intervals, target temperature thresholds and battery pack life; and performing thermal management on the battery pack based on the target temperature threshold; where the performing thermal management on the battery pack based on the target temperature threshold comprises cooling the battery pack based on the target temperature threshold.
