The energy storage container system is an integrated energy storage system developed for the needs of the mobile energy storage market. It integrates battery cabinets, battery management systems (BMS), container dynamic ring monitoring systems, and can integrate energy storage converters and energy management systems according to customer needs. The energy storage container system has the characteristics of simplifying the establishment of basic equipment, short establishment cycle, high degree of modularity, easy transportation and installation, and can be applied to thermal, wind, solar and other power stations or islands, communities, schools, scientific research institutions, factories, large load centers and other applications. The total amount of energy storage containers is large, which is a strong support and foundation for the energy Internet and smart grid, as well as future power innovation. The container energy storage device integrates lithium iron phosphate battery pack, battery management system, energy storage cabinet and communication monitoring, which is equal to one standard unit. The standard unit has independent power supply system, temperature control system, heat insulation system, flame retardant system, fire alarm system, safety escape system, emergency system, fire fighting system and other automatic control war security guarantee systems.
