Lithium precipitation detection method, electronic equipment and battery system

The embodiment of the invention provides a lithium precipitation detection method, electronic equipment and a battery system, and the lithium precipitation detection method comprises the steps: obtaining a plurality of candidate values of a predetermined charging parameter and first data corresponding to each candidate value, the first data is obtained when the charging device performs first intermittent charging on the electrochemical device which is not loaded on the application equipment according to a candidate value corresponding to the first data; selecting a target value from a plurality of candidate values according to the first data; using the target value to enable the charging device to perform second intermittent charging on the electrochemical device loaded on the application equipment to obtain second data; and determining whether the electrochemical device precipitates lithium according to the second data. The lithium precipitation detection method can effectively perform lithium precipitation
