The invention relates to a battery abnormity early warning method, device and equipment and a storage medium, and relates to the technical field of electric vehicle battery abnormity detection. The method comprises the steps of obtaining multiple pieces of target training data; the target training data comprises a feature vector composed of multiple pieces of battery feature data; inputting the plurality of target training data into a target neural network model based on a preset sliding window step length for training, and generating at least one first target prediction value corresponding to the at least one feature vector; the target neural network model comprises a long short term memory (LSTM) model and a local attention model; comparing at least one first target prediction value corresponding to the at least one feature vector with a safety threshold, and determining an abnormal feature vector; generating abnormal early warning information based on the abnormal feature vector; the abnormity early warning information comprises abnormal battery characteristic data and abnormity processing measures. Therefore, the technical problem of battery abnormity early warning accuracy in related technologies can be solved.
