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.

Abstract: A battery housing structure includes a housing, an end plate, and a first sealing element. The housing is a tubular structure with an opening at an end, and the tubular structure is configured to accommodate a battery cell. The end plate is mounted at an end of the housing. The housing and the end plate jointly form an accommodation space. The battery cell is disposed in the accommodation space. The first sealing element is disposed between the end plate and the housing so that the accommodation space is hermetically sealed.
