Original Abstract Submitted

a battery management system that identifies short-circuits during a recharging cycle by identifying data indicative of potential battery failures. the system identifies an unstable operating interval that lies between a healthy and failing battery operating state and labels data within the unstable operating interval to generate a battery profile. the system trains a predictive model by sampling a portion of the battery profile and executes a trained predictive model to render predictions of a battery failure. it executes preventive measures in response to failure predictions during the battery recharging cycle. the battery management system mitigates short-circuits including those caused by lithium dendrites that pierce the separator that isolates the anode from the cathode. further, the battery management may communicate with local and remote users in response to short-circuit detections.
