Technical Field

[0001] The utility model relates to the field of electrical technology, in particular to a confluence control cabinet for pre-set storage energy. Background Art

[0002] At present, the mainstream in the market are integrated energy storage and containerized energy storage. For those with relatively large capacity requirements, containerized energy storage cabinets are mainly used. The sizes of containerized energy storage cabinets are generally 20 feet and 40 feet, with a height of about 2.6-2.9 meters and a width of about 2.4-2.6 meters. For industrial and commercial energy storage, 20 feet is commonly used, with a capacity of 1mWh to 5mWh.

[0003] Energy storage systems usually include batteries and battery management systems (BMS), power converters (PCS), energy management systems (EMS) and other electrified components. Usually, a pre-installed warehouse is divided into a battery part, an EMS control part, a DC bus part, a ventilation and heat dissipation part, and an auxiliary power supply circuit in the warehouse. With the development of the market, users have higher and higher requirements for capacity, resulting in an increasing demand for battery warehouse space, and also generating greater requirements for the performance and space size of other functional modules in the warehouse.

[0004] Since the size of the pre-set warehouse is fixed, if the battery capacity required by the user increases, the space of the battery warehouse needs to be increased, resulting in the compression of the space of the power distribution and control part on the other side. In addition, the existing EMS cabinet (EMS control part), junction cabinet (DC junction part) and auxiliary power cabinet (auxiliary power circuit in the warehouse) are independently set and arranged separately, and the connection between the cabinets needs to be arranged. If the design is not good, the various primary and secondary interlocking lines will be relatively messy, which will bring inconvenience to the user's operation and maintenance, and easily increase the occurrence of faults.

The front cabinet door 112 can be opened, and the opening method can be overall disassembly or hinge connection.

[0045] The auxiliary power module 12 is accommodated in the accommodating cavity 111. The auxiliary power module 12 is provided with an auxiliary power circuit for providing power for fire protection, heat dissipation, battery cluster power and various secondary control circuits of the entire prefabricated warehouse, so as to ensure the stable operation of the system.

[0046] The DC bus module 13 is accommodated in the accommodating cavity 111 and is used for charging and discharging between the battery cluster and the external power distribution network in the energy storage system.

[0047] The communication control module 14 is fixed to the front cabinet door 112. Here, the communication control module 14 is also accommodated in the accommodating cavity 111.

[0048] The communication control module 14, the auxiliary power module 12, and the DC bus module 13 are all independently configured. The independent configuration here specifically means that the three as a whole have no intersection in the installation position and are independent of each other, but there is still a certain electrical connection between them, for example, the auxiliary power module 12 will supply power to the communication control module 14, etc. This structural setting integrates the three cabinets 11 into one cabinet 11. Through the layout design, the three modules do not interfere with each other, ensuring normal functional use. Moreover, after the merger, the space of the preset warehouse is saved, so that there is more space for battery expansion and increased capacity; at the same time, the communication control module 14 is fixed to the front cabinet door 112, which makes it more convenient during maintenance, and the accident point can be quickly found, or the whole can be replaced, which has higher maintenance efficiency.
