[0002] Integrated energy storage units are a type of energy storage technology that converts excess electrical energy in a power system into electrical energy. Through a series of storage and release devices, they achieve peak-valley power regulation, fault-tolerant power supply, and backup power for the power grid. They can be applied to various power systems, reducing grid transients, improving energy utilization, mitigating power supply and demand imbalances, and ensuring stable power supply. This results in energy conservation and environmental protection, significantly improving the development of the domestic power industry and the quality of electrical equipment.

At the same time, it is suitable for a variety of application scenarios, including grid-connected power generation, off-grid power supply and microgrids, to meet the energy needs of different users.

[0005] To address the aforementioned technical problems, this utility model provides a 100kW-215kWh air-cooled energy storage integrated unit, comprising a frame, an upper chamber and a lower chamber on the frame, an energy storage battery pack inside the upper chamber, a high-voltage box located near the upper chamber in the lower chamber, an energy storage converter at the bottom of the high-voltage box, and a protection module located on the side of the high-voltage box inside the lower chamber; it also includes an outer shell, an air conditioning component located on the outer shell corresponding to the position of the upper chamber, and a control module located outside the outer shell.

[0006] Furthermore, the protection module includes a surge protector, a main power circuit breaker, and a miniature circuit breaker.

[0011] The beneficial effects of this invention are as follows: This device adopts advanced power electronics technology and efficient control algorithms, achieving an energy conversion efficiency of over 98%, reducing system losses and improving energy utilization. Furthermore, this integrated unit uses high-quality components and rigorous manufacturing processes, exhibiting excellent stability and reliability, ensuring safe operation of the system under various working conditions. By installing a new converter, rationally arranging the layout, and optimizing the air duct, cool air is delivered to the rear of the battery module, where it is then exhausted by the battery module's exhaust fan and delivered as hot air by the air conditioning fan. Simultaneously, it is suitable for various application scenarios, including grid-connected power generation, off-grid power supply, and microgrids, meeting the energy needs of different users.
