The container energy storage system is an integrated energy storage system developed to meet the needs of the mobile energy storage market. It integrates battery cabinets, battery management systems, monitoring systems, fire protection systems, and can integrate energy storage converters and energy management systems according to customer needs.
Energy storage system containers have the characteristics of simplifying infrastructure construction costs, short construction cycles, high modularity, and easy transportation and installation. They can be used in power plants such as thermal power, wind energy, solar energy, or in applications such as islands, communities, schools, research institutions, factories, and large load centers. Its performance and characteristics include the following aspects:
1、The energy storage system container has good environmental adaptability, and has functions such as anti-corrosion, fire prevention, waterproof, dustproof (wind and sand), shockproof, UV resistant, anti-theft, lightning resistant, and wind resistant. Under periodic routine maintenance, it must be ensured that the prefabricated cabin will not malfunction due to corrosion, fire prevention, waterproof, dustproof, and UV resistant factors for 25 years.
2、The container steel structure must use high weather resistant steel plates with comparable performance, with a flat top structure for easy stacking.
3、The container adopts a two-layer steel plate shell, and the filling material in the middle must be A-grade fire-resistant and flame-retardant rock wool, which must have waterproof function. The filling thickness of the side walls, top, door, and bottom of the container is between 50mm.
4、The container should be equipped with an escape door that directly connects to the outside, using a sliding door type external door for easy evacuation. The box is equipped with double louver doors and ventilation louvers to facilitate equipment entry and exit as well as equipment heat dissipation requirements. The battery compartment is separated from the equipment compartment by a fireproof partition wall. An escape door is installed on the partition wall, and a sliding door type escape door lock is installed, which opens from the battery compartment to the equipment compartment. All outdoor doors are equipped with efficient waterproof adhesive strips to meet the protection level.
5、Four symmetrical grounding points should be set at the four corners outside the box, with obvious grounding signs. All electrical equipment and cabinets should be grounded nearby.
6、The container is required to have a load capacity of ≥ 36T, and the design structure of the container must meet the load capacity requirements.
7、The container needs to meet three layers of protection: the primer is zinc rich paint, the intermediate paint is epoxy paint, the outer paint is acrylic paint, and the chassis is asphalt paint.
8、The interior space of the box is designed with air conditioning ducts, which improves the battery's heat dissipation speed, reduces energy consumption, and enhances the safety performance of the box.
9、The basic framework of the battery rack inside the box is a combination assembly structure, with electrostatic spraying on the surface. All metal structural components have undergone special anti-corrosion treatment to have anti-corrosion and aesthetic performance. The structure is safe and reliable, with sufficient mechanical strength to ensure that there is no shaking or deformation during component installation and operation. The design of the battery rack also needs to consider easy installation and maintenance.
In summary, the energy storage system container must meet the design requirements through the above technical performance and characteristics in order to ensure the continuous and stable operation of the energy storage system.
