Technical Field

[0002] Energy storage systems are technologies used to store electrical energy, capable of releasing it when needed and retaining it when not needed. Energy storage systems can help balance the load on the power grid, allowing renewable energy to be stored when it is overproduced and to generate electricity when demand is high. In addition, energy storage systems can also improve the reliability of the power grid, shorten power outages, reduce the cost of energy supply, and reduce dependence on fossil fuels.

[0003] In most current energy storage systems, the DC side and AC side are designed independently of each other, with the battery compartment being the DC side and the boost converter compartment being the AC side. Generally, the battery compartment and the boost converter compartment are installed in different prefabricated compartments. However, this type of energy storage system has the following shortcomings: 1) The battery compartment and the boost converter compartment are independent of each other and occupy a large area; 2) The connection between the DC side and the energy storage converter needs to be connected through a pre-buried pipe with cables. Due to the large amount of cables, the final installation workload increases; 3) The energy storage system has a large charging and discharging current, and the cross-sectional area of ​​the required cables is also relatively large, which increases the cost of cable use; 4) The cables are installed between the compartments and are easily damaged during construction.
