Description
Technical Field

[0002] In power systems, power conversion systems (PCS) play a crucial role, converting electrical energy from storage devices into a form suitable for the grid or loads. However, existing energy storage modules suffer from numerous design flaws that limit their performance and reliability in practical applications.
[0003] First, existing energy storage modules have complex structures, containing multiple electrical units and auxiliary components. The connection and assembly processes between these components are cumbersome and time-consuming. This complex structure not only increases production costs but also potentially introduces points of failure, reducing the overall reliability of the system. Second, existing energy storage modules have significant shortcomings in terms of protection. Due to limitations in their structural design, these modules often struggle to effectively resist external environmental factors such as dust and moisture. Especially when used outdoors or in harsh environments, the intrusion of dust and moisture can damage or degrade internal electrical components, thus affecting the normal operation of the energy storage converter. Furthermore, existing energy storage modules also present certain problems in terms of production costs. Due to their complex structure, a large number of screws and other connectors are needed to secure the various components, which not only increases material costs but also enhances assembly complexity. Simultaneously, the division between functional units is not clearly defined or rationally planned, leading to an excessive number of power terminals, further increasing production costs.
[0004] Therefore, providing a more efficient, reliable, and cost-effective energy storage converter module has become an urgent problem to be solved in this field. Utility Model Content

[0033] The enclosure 1 houses a power processing unit, a communication unit 3, a heat dissipation and ventilation unit, and a partition support unit. The power processing unit includes an input / output unit 7, a filtering unit 8, and a power unit 6 connected in sequence. The input / output unit 7 is connected to power terminals 2 for connecting to the power grid and a battery. The partition support unit includes a middle partition 108, which divides the enclosure 1 into upper and lower parts. The heat dissipation and ventilation unit and the filtering unit 8 are located below the middle partition 108.

[0035] This utility model discloses an energy storage converter module. The electrical unit of this energy storage converter module consists of only four parts: a power unit, an input / output unit, a filtering unit, and a communication unit. Compared with the traditional complex energy storage converter structure, this design greatly simplifies the assembly process, reduces assembly steps, and thus effectively reduces assembly time and improves production efficiency. Due to the simplified structural design, the number of screws required during the assembly process of the energy storage converter module of this invention is also reduced accordingly. This not only reduces material costs but also reduces the extra labor time caused by screw installation, further reducing production costs. The housing is divided into upper and lower parts by a middle partition, achieving a reasonable layout of the power unit, input / output unit, heat dissipation and ventilation unit, and filtering unit. This layout not only facilitates heat dissipation and ventilation but also improves the compactness and stability of the module's internal structure, thereby enhancing the overall performance and reliability of the energy storage converter module. The middle partition allows the heat dissipation and ventilation unit and the filtering unit to be concentrated at the bottom for efficient heat dissipation, while the input / output unit and the power unit, which do not require heat dissipation, are placed at the top. This design effectively avoids the impact of dust and moisture on the upper-level electrical units, improving the environmental adaptability and protection of each upper-level board, thereby extending the service life of the energy storage converter module. In summary, the energy storage converter module proposed in this invention demonstrates significant benefits in simplifying the assembly process, reducing production costs, improving overall module performance and reliability, and optimizing heat dissipation.
[0036] The working principle of this utility model is as follows:
[0037] When the energy storage converter module is working, the current flows in the following direction: the mains power is connected to the input stage of power terminal 2, and the current flows through the input stage of terminal 2---copper busbar 9---input / output unit 7---power support column 10---filter board 8---cable 11---power unit 6---input / output unit 7---copper busbar 9---output stage of terminal 2. The current flows in the above order.
[0038] The power transistor 601 on the power unit 6 is in close contact with the heat sink 5. When the energy storage converter module is working, the heat on the power transistor 601 is transferred to the heat sink 5. The fan 4 draws in cold air from the mesh of the front panel 104 and blows it onto the heat sink 5. The heat is transferred to the cold air through heat exchange, and the heated cold air is discharged from the rear panel 106 from the enclosure 1.
[0039] The rated power of the energy storage converter module used in this invention can reach 125KW, while the power of common modular active filter devices on the market is 65KW to 100KW. The energy storage converter module used in this invention is divided into four parts: a power unit, an input / output unit, a filter unit, and a signal unit. It features high unit integration, a simple structure, and easy production and assembly, reducing material usage and processing costs. The energy storage converter module is layered, with units that are less environmentally adaptable or do not require heat dissipation placed on the upper layer. This eliminates the need for air exchange with dusty and humid environments, preventing dust and water accumulation and improving the overall environmental adaptability and protection of the equipment.
[0040] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
