Abstract

The invention provides a battery anomaly detection method and device, an electronic device and a storage medium, and is applied to the technical field of battery detection. The method comprises the steps: obtaining target behavior data of a to-be-detected battery; performing self-adaptive transfer learning on a first detection model by using the target behavior data to obtain a second detection model, wherein the first detection model is obtained by pre-training according to historical behavior data of a compliant battery; obtaining a second deviation degree of the second detection model; andunder the condition that the second deviation degree is greater than a deviation degree threshold, determining that the to-be-detected battery is an abnormal battery, wherein the deviation degree threshold is obtained in advance according to a first deviation degree of the first detection model. According to the scheme, various potential abnormal behaviors of the to-be-detected battery can be effectively detected, and manpower and computing resources required by training of the battery detection model are greatly reduced.

Description

technical field [0001] The present application belongs to the technical field of battery detection, and in particular relates to a battery abnormality detection method, device, electronic equipment and storage medium. Background technique [0002] With the development of scientific level and social progress, many types of new energy vehicles have appeared on the market, among which the prospect of electric vehicles is widely optimistic. Battery technology is one of the main bottlenecks restricting the development of electric vehicles. Accidents due to abnormal battery behavior also occur frequently. Therefore, if the abnormal behavior of the power battery is not detected in time, it will seriously threaten the safety of users' lives and property. [0003] In the prior art, various detection models such as equivalent circuit model, electrochemical model and empirical model are usually established, and by obtaining the normal fluctuation range of the specific behavior paramete...
