Abstract: A speech recognition method includes: inputting a speech into a speech recognition model which includes N hidden layers; predicting speech recognition accuracy corresponding to the ith hidden layer according to the hidden layer information and an accuracy prediction model that are corresponding to the ith hidden layer, the speech recognition accuracy indicating a degree of matching between a speech recognition result determined according to the hidden layer information of the ith hidden layer and an accurate speech recognition result corresponding to the speech; outputting the hidden layer information corresponding to the ith hidden layer to an (i+1)th hidden layer in response to that the speech recognition accuracy does not meet the result output condition; and outputting the hidden layer information corresponding to the ith hidden layer to the output layer in response to that the speech recognition accuracy meets a result output condition, to obtain the speech recognition result.

Abstract: A sampling structure includes a battery information collector, a plurality of fuses, and a plurality of collection lines. First ends of the collection lines are configured to be connected with corresponding batteries. Connection terminals are arranged on second ends of the collection lines. A plurality of pads are arranged on the battery information collector. First ends of the fuses are welded to the corresponding connection terminals. Second ends of the fuses are welded to the corresponding pads.

Abstract: A battery pack includes a box, a sealing cover, a battery string, a sampling structure, and a battery information collector configured to be connected with a battery management system. The battery string and the sampling structure are arranged inside the box. The battery string includes multiple electrically connected batteries. The sampling structure includes multiple sampling lines. First ends of the sampling lines are connected with the corresponding batteries. Second ends of the sampling lines are connected with the battery information collector. The box is provided with an opening. The battery information collector is arranged at the opening of the box. The sealing cover is located on an outer side of the battery information collector. The sealing cover is configured to seal the opening of the box.
