    • An electric spoiler control method. The electric spoiler control method comprises: acquiring the current position of an spoiler, and determining, according to the current position of the spoiler and a preset position of the spoiler, whether the spoiler is offset (S 1); when it is determined that the spoiler is offset, outputting an offset signal related to the offset of the spoiler (S2); when a confirmation adjustment signal for the offset signal is detected, controlling the spoiler to enter an spoiler self-learning state, wherein the spoiler self-learning state comprises controlling the spoiler to execute a preset learning action between a plurality of calibration positions (S3); and acquiring an actual position of the spoiler, and when it is detected that an offset value between the actual position and the corresponding calibration position is less than a preset offset value, determining that spoiler self-learning is successful (S4). Further disclosed are an electric spoiler control apparatus, and an electronic device, a vehicle and a computer program product, which include the control method. By means of the control method, the problem of it being impossible to correct the angle of an spoiler in time when the spoiler is offset is solved, thus effectively improving the applicability of the spoiler.

    • A performance detection method of the battery thermal management system and a related device are provided in the disclosure, in which a current battery temperature matrix is built based on battery pack operating condition data of a current electric vehicle in a current preset time of period, the current battery temperature matrix is a three-dimensional matrix of battery pack output voltage subintervals, battery pack output current subintervals, and single-cell temperature maximum values in the battery pack. A quotient of each single-cell temperature maximum value in the current battery temperature matrix and corresponding reference single-cell temperature maximum value in a reference battery temperature matrix is formed to obtain a temperature offset of single cell, and all of temperature offsets of single cells are averaged to obtain an attenuation constant characterizing performance attenuation of the battery thermal management system. According to the disclosure, the performance detection of the battery thermal management system is realized based on the battery pack operating condition data of the electric vehicle, and it can be determined whether performance of the battery thermal management system degrades or fails according to the attenuation constant characterizing the performance attenuation of the battery thermal management system.
