Improving and optimizing the safety standards of energy storage systems is an urgent task

　　In recent years, energy storage system accidents have occurred frequently all over the world.

　　In April 2021 alone, there have been major accidents such as a fire in the LG Chem photovoltaic energy storage system in South Korea and an explosion in the energy storage power station of Beijing Gotion Full-service Optoelectronics Storage and Charging Technology Co., Ltd.

　　These energy storage accidents undoubtedly have important warning significance for the entire industry.

　　When the energy storage industry is about to enter the stage of large-scale development, it is very necessary to conduct safety inspections, analysis and even rectification of existing energy storage projects in operation and under construction in accordance with relevant standards.

　　In fact, the safety issue of energy storage systems is not simple. It is a complex system engineering that requires enterprises to have systematic thinking. The energy storage system is valuable only when the safety measures are taken from the perspective of the system.

　　From battery cell procurement, battery PACK development, battery pack production, to the entire DC container design, the realization of the management cooperation with the AC side, as well as the coordination and cooperation between PCS, BMS and EMS, all have to go through a lot of rigorous work.

　　For example, safety and reliability, fire protection system, use environment and application scenarios should be considered as a whole. Keep the battery working in a comfortable state, try to maintain battery consistency, and increase the charge and discharge capacity as much as possible, which is conducive to the stable operation of the system.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and they are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data center and other industries.

　　Energy storage can't just talk about price, otherwise quality and profit will not be guaranteed. Improving and optimizing the safety standards of energy storage systems is an urgent task.
