• Cascading failures: The failure of one piece of equipment can trigger a chain reaction, leading to a wider outage. Imagine a transformer malfunctioning in a power substation. This can cause a surge or voltage drop, tripping other protective devices and potentially taking down entire sections of the power grid. Human errors:
Failure to deactivate a false alarm could lead to unnecessary release of fire extinguishing agents or unwanted sprinkler-system activation, which could cause serious damage to energy storage equipment. Typical thermal management system-related defects were coolant leaks due to defective valves and loose pipe connections.

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.
Root Cause of Failure: Design, manufacturing, integration/assembly/construction, or operation. Affected BESS Element: Cell/module, controls, or balance of the system. The study analyzes the proportion of failures associated with each root cause and BESS element, the relationship between the two, and trends in failure types and rates over time.
The operation data of actual energy storage power station failure is also very few. For levels above the battery pack, only possible fault information can be obtained from the product description of system devices. The extraction of the mapping relationship from symptoms to mechanisms and causes of failure is incomplete.
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.
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.
