The embodiment of the invention discloses a multi-mode battery detection method and device,
electronic equipment and a storage medium, and relates to the technical field of battery management, and the method comprises the steps: obtaining multi-dimensional
original data such as battery temperature and
voltage, carrying out the preprocessing, dividing the data according to a working state mode through KMeans clustering, constructing a
data set through combining diversity sampling, and carrying out the detection of a multi-mode battery; and carrying out
standardization processing and constructing a sliding window to obtain a
time series data set. A single-layer LSTM network and a graph neural network are adopted to construct a dual-path
encoder joint model based on a variational auto-
encoder framework, and training is carried out. After to-be-detected data is obtained, the data is segmented by a sliding window, and the dependency relationship between the
time sequence and the features is extracted respectively for splicing and compression. And restoring the sequence into a reconstruction sequence through a three-layer full-connection network, and calculating a
mean square error and a regularization term to obtain a
reconstruction error. And setting a dynamic threshold value, judging that an error is abnormal if the error exceeds the threshold value, calculating a feature contribution degree and generating a visual report. According to the method, the problems of low accuracy and efficiency and poor result
interpretability in the prior art are effectively solved.
