摘要： A battery cell includes a housing, an electrode assembly accommodated in the housing, and an end cover configured to buckle to an opening of the housing. The end cover comprises a first body part, a first end wall, and a first peripheral wall. The first body part is configured to be connected to the housing. The first end wall is farther away from the electrode assembly than the first body part. The first peripheral wall is disposed around an edge of the first end wall and connected to the first body part, and the first peripheral wall and the first end wall jointly form a first accommodation space used to accommodate at least a part of a tab of the electrode assembly. The first peripheral wall comprises a first arc wall extending from the first end wall to the first body part along a first arc trajectory.

摘要： 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.
