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.
Battery management system fault BMS faults mainly include data asynchronism, communication failure, acquisition failure, control failure, and short circuit of the BMS.
There has been a dramatic fall in failures of stationary battery energy storage over the past 5 years.
In this paper, the fault diagnosis of battery systems in new energy vehicles is reviewed in detail. Firstly, the common failures of lithium-ion batteries are classified, and the triggering mechanism of battery cell failure is briefly analyzed. Next, the existing fault diagnosis methods are described and classified in detail.
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.
We review the possible faults occurred in battery energy storage system. The current research of battery energy storage system (BESS) fault is fragmentary, which is one of the reasons for low accuracy of fault warning and diagnosis in monitoring and controlling system of BESS.
