Energy storage containers, abbreviated as HSEC, are a new generation of container energy storage solutions. Using containers as carriers, it is composed of battery packs, battery management systems (BMS), energy storage inverter systems, power distribution systems, temperature control (ventilation, refrigeration) systems, lighting systems, fire protection systems, monitoring systems, and grounding systems. Integrate lead-acid batteries, battery management systems, battery DC converging devices, energy storage bidirectional converters, communication monitoring and other equipment into the container unit.
