Energy storage containers represent a new generation of containerized energy storage solutions. Using standardized containers as the platform, they integrate battery packs, battery management systems, energy storage inverter systems, power distribution systems, temperature control systems, lighting systems, fire protection systems, monitoring systems, and grounding systems. Lead-acid batteries, battery management systems, battery DC bus equipment, bidirectional energy storage converters, communication monitoring equipment, and other devices are organically integrated into the container unit. This standardized unit features independent power supply systems, temperature and humidity control systems, thermal insulation systems, flame retardant systems, fire alarm systems, lightning protection systems, electrical interlock systems, mechanical interlock systems, safety escape systems, emergency systems, fire protection systems, and other automatic control and safety systems to ensure a safe and stable operating environment for lead-acid batteries and enable remote monitoring.
