This work proposes a novel data-driven method to detect long-term latent fault and abnormality for electric vehicles (EVs) based on real-world operation data.
Customer ServiceIn numerous instances, the Battery Management System (BMS) proved incapable of averting or handling these circumstances, resulting in battery failure. Another prevalent factor pertains to flaws in the design and manufacturing of the battery.
In the published accident investigation reports of BESS, failure causes and influencing factors would be summarized as follows: defects in battery cell, defects in components, external excitations, application environment, system layout, state of battery and management system defects.
There are many failure modes and causes of BESS, including short-time burst and long-term accumulation failure, battery failure and other components failure. At present, the fault monitoring and diagnosis platform of BESS does not have the ability of all-round fault identification and advanced warning.
These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
