Description

Technical Field

[0001] This application relates to the field of flow battery technology, and in particular to a signal acquisition and control box for a flow battery stack rack. Background Technology

[0002] Flow battery energy storage systems are a new type of green electrochemical energy storage device. They have advantages such as good safety, long service life, and independent design of power and capacity. They can be used not only as energy storage devices in conjunction with solar and wind power generation processes to smooth the fluctuations in renewable energy power generation and ensure the stable power supply of renewable energy power generation systems, but also for grid peak shaving to improve grid stability and ensure grid security.

[0003] As an electrochemical reaction system, the safe, reliable, and stable operation of a flow battery energy storage system is paramount during application. This requires real-time monitoring and control of the power unit (stack), energy storage unit (electrolyte and tank), and electrolyte delivery unit (pipelines, valves, pumps, heat exchangers, etc.) status to ensure reliable and efficient operation of the flow battery system and safe stack operation. Existing flow battery systems centralize the control and monitoring of the power unit, energy storage unit, and electrolyte delivery unit within the battery management system (BMS) cabinet. This results in a large BMS cabinet size, complex wiring, and a lack of modularity and scalability, significantly limiting the flexibility of flow battery BMS configurations. Utility Model Content

[0005] A signal acquisition and control box for a flow battery stack includes a box body, a left inner mounting plate, a right inner mounting plate, a left door, and a right door. The box body includes a bottom wall and four side walls connected end to end, as well as a partition plate that divides the box body into a power supply area and a control power supply area. The left door and the right door are respectively installed on the left and right sides of the box body, and the left inner mounting plate and the right inner mounting plate are respectively installed on the left and right sides of the box body. The left inner mounting plate sequentially includes a three-phase power distribution area, a frequency converter area, and a power supply grounding copper strip area. The right inner mounting plate sequentially includes a single-phase power distribution area, a processor and intermediate relay area, a stack voltage acquisition area, a terminal block wiring area, and a control power supply grounding copper strip area.

[0006] Preferably, axial flow fans are installed on the left wall of the housing and the lower part of the left side door to serve as air outlets and air inlets, respectively, for heat dissipation of the frequency converter.

[0007] Preferably, an LED light tube is installed on the top right side of the enclosure for maintenance lighting.

[0008] Preferably, two wiring holes are opened at the bottom of the partition in the enclosure for connecting wiring between the power supply area and the control power supply area.

[0009] In summary, this application includes at least one of the following beneficial technical effects:

[0010] 1. The signal acquisition and control box of the flow battery stack rack in this application is independently arranged on the stack rack and transmits the signal to the battery management system cabinet through communication, which reduces the size of the cabinet; the wiring is simple and flexible expansion is possible.

[0011] 2. The signal acquisition and control box of the flow battery stack rack in this application adopts a partition design to separate the frequency converter from the control and signal acquisition components, and heat dissipation treatment is carried out in the frequency converter compartment to ensure that the components inside the box operate at a good temperature.
