The invention provides a vehicle early warning method, device and equipment and a storage medium, and relates to the technical field of vehicle early warning, the method comprises the steps that a battery pack early warning parameter time sequence set of each vehicle is acquired, and the early warning parameter time sequence set comprises a pressure difference time sequence set, a temperature difference time sequence set and a pressure difference entropy time sequence set; determining a feature vector corresponding to each vehicle according to the early warning parameter time sequence set, wherein the feature vector comprises a pressure difference dimension component, a temperature difference dimension component and a pressure difference entropy dimension component; dividing the feature vectors corresponding to the vehicles into a plurality of sets, wherein each set comprises the feature vectors corresponding to the vehicles with the same battery pack type; and based on an anomaly detection algorithm, determining an abnormal vehicle according to the feature vectors corresponding to the vehicles in each set. The abnormality of different vehicle battery packs is evaluated by integrating the multi-dimensional battery pack performance parameters, the consideration is more comprehensive, the accuracy of abnormal battery pack identification is improved, and the accuracy of vehicle early warning is improved.
