Description

Technical Field

[0001] The utility model relates to the field of energy storage, and in particular to a control box and an energy storage cabinet. Background Art

[0002] As the market for energy storage systems continues to expand, control boxes are gradually replacing and upgrading small traditional energy storage equipment due to their larger volume and energy, faster response speed, richer application scenarios, and more comprehensive functional coverage.

[0003] However, since the control box system complies with the relevant industry standards and technical specifications of the energy storage system, it has certain requirements for sub-units such as fire protection, environmental monitoring, system power distribution, system control and communication. At the same time, as the energy storage system is a cutting-edge field, all relevant manufacturers hope to ensure the uniqueness of their own products. Therefore, the current more common control box integration method is: separate design and integration for each system, and integration of related functions based on the characteristics of the manufacturer's own equipment. In the above integration method, each system is relatively scattered, which increases the difficulty of control box integration. At the same time, some functions are bound to the products of equipment manufacturers, reducing the possibility of standardized and systematic production of control boxes. Utility Model Content
