Zusammenfassung:The embodiment of the invention provides an electrochemical device lithium precipitation detection method and electronic equipment. The method comprises the following steps: acquiring current charging state data of a to-be-tested electrochemical device; inputting the current charging state data into a pre-trained BP neural network to obtain the lithium precipitation degree of the electrochemical device corresponding to the current charging state data; wherein the BP neural network is obtained by training according to the charging state data of each sample and the lithium precipitation degree true value of the electrochemical device corresponding to the charging state data of each sample. As the scheme does not need to introduce any special charging working condition, such as a pulse working condition, to the electrochemical device to be tested, the implementation is convenient. Meanwhile, the BP neural network has high self-learning and self-adaptive capabilities, so that the lithium precipitation degree of t
