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: Embodiments of the present invention provide a method and a device for detecting SOC of a battery. The method for detecting SOC of a battery includes: determining an initial SOC value of the battery according to a waiting time of the battery; calculating a current SOC value of the battery based on the initial SOC value and a current working current of the battery, denoting as a first SOC value. In embodiments of the present invention, the current of the battery is real-time measured and the SOC value of the battery is calculated by accumulating the current of the battery, in addition, the initial SOC value is calibrated by the waiting time, so that the error of the SOC detection result is reduced, thereby increasing accuracy of the SOC detection result.

Abstract: A position assurance apparatus, which is used for a connector assembly connected to a signal circuit are provided. The connector assembly comprises a first connector and a second connector, which are connected in pairs, wherein the first connector is connected to the signal circuit, and the second connector is inserted in the first connector. The position assurance apparatus comprises a first connecting portion and a second connecting portion, which are electrically connected to each other. The first connecting portion and the second connecting portion are configured to be electrically connected to the signal circuit by means of the first connector, so as to turn on the signal circuit when the first connector and the second connector are inserted in place.
