Abstract:

Energy storage technology, which has attracted extensive attention all over the world, is the key to supporting energy transformation and the smart grid. Due to its high energy density, long cycle life, and environmental friendliness, the lithium-ion battery has become one of the preferred storage carriers for large-scale energy storage. The magnitude of energy storage has been observed to increase continually. However, fire accidents have occurred frequently in lithium-ion battery energy storage systems, limiting their further application. Because of this problem, this study compares the representative safety test standards of lithium-ion battery energy storage at home and abroad, for example, foreign standards such as IEC 62619, IEC 63056, UL 1973, and UL 9540A, as well as national, industrial, and alliance standards such as GB/T 36276 and T/CNESA 1004. Further, the test methods for thermal runaway are analyzed at the cell, module, unit, and installation levels according to the characteristics of the energy storage system. Finally, the shortcomings of the current standards are revealed, and several proposals are advanced to promote the safe and efficient operation of energy storage systems.
