Energy storage system falsely reports battery failure

An analysis of li-ion induced potential incidents in battery

Lithium-ion battery energy storage system (LIBESS) requires a large number of interconnected battery modules to support the normal operation of the energy storage system when storing, converting and releasing electrical energy. Therefore, once a battery unit fire occurs in a relatively closed storage space, it is easy to cause a chain combustion reaction of
