The invention discloses a power battery safety state detection method, electronic equipment, a storage medium and a device. The method comprises the steps that a power battery is charged based on a pulse charging strategy, battery pulse charging data of each pulse charging stage, battery quasi-static data of each quasi-static stage and charging end moment data are collected, and data cleaning is carried out; determining a battery monomer with the highest voltage in each quasi-static stage based on the battery quasi-static data subjected to data cleaning, and calculating the occurrence frequency of each battery monomer in all quasi-static stages; identifying whether all the battery monomers have outlier battery monomers or not through a k-means clustering algorithm based on the frequency; and analyzing the safety state of the power battery based on the identification result, the battery pulse charging data, the battery quasi-static data and the charging end moment data. According to the invention, the pulse charging strategy is adopted to charge the power battery and collect the pulse charging data, so that the safety state of the battery can be detected without cloud data.
