Description
The technical field is as follows:
the utility model relates to a vanadium cell field specifically is a vanadium cell management system, especially operation management system to vanadium cell.
Background art:
the vanadium battery management system is a system for converting and storing energy of wind energy, solar energy and other energy sources and chemical energy, and the main unit of the management system is a vanadium battery. Compared with traditional batteries such as lead-acid batteries and the like, the battery has uniqueness in internal and external structures and operation modes, and is more suitable for large-scale energy storage power stations such as wind energy and solar energy, smart grid peak shaving and other application occasions in performance. The cell stack is formed by arranging and assembling single cells with different numbers according to the required electric power. The output power of the cell stack is determined by the total area of the cell plates, and the capacity of the cell is determined by the total capacity of the electrolytic solution.
The common storage battery management device can only measure data such as battery voltage, single-electrode internal resistance, temperature, charging and discharging current and the like, can store the generated data, and can alarm when the internal resistance and the alarm event exceed limits, but the functions can not meet the requirement of the operation management of the vanadium battery.
Vanadium Redox Batteries (VRBs) are a mobile battery that is currently being phased into commercialization. As a chemical energy storage technology, VRB has many unique design points and performance characteristics compared to conventional lead-acid and nickel-cadmium batteries, and is suitable for various industrial situations, such as: can replace oil engines, standby power supplies and the like. Vanadium batteries convert the energy stored in an electrolyte into electrical energy by exchanging electrons between two different types of vanadium ions separated by a membrane. The electrolyte is formed by mixing sulfuric acid and vanadium, and the acidity of the electrolyte is the same as that of a traditional lead-acid battery. Since this electrochemical reaction is reversible, VRB batteries can be either charged or discharged. During charging and discharging, the electric energy and the chemical energy are converted with the change of the concentration of the two vanadium ions. A VRB cell consists of two electrolyte cells and a layer of cells. The electrolyte cell is intended to contain two different electrolytes, each cell consisting of two "half-cells" sandwiching a separator and electrodes for collecting the current. Two different "half-cells" hold electrolytes of vanadium in different ionic forms. Each electrolyte cell is provided with a pump for delivering electrolyte to each "half cell" in a closed conduit. When the charged electrolyte flows in the cell layers, electrons flow to an external circuit, which is a discharge process. The reverse occurs when electrons are delivered from the outside to the inside of the cell, which is to charge the electrolyte in the cell and then pumped back to the electrolyte reservoir. In VRB, electrolyte flows between a plurality of battery cells, and the voltage is formed by connecting the cell voltages in series, and the nominal voltage is 1.2V. The current density is determined by the surface area of the current collector within the cell, but the supply of current is dependent on the flow of electrolyte between the cells, rather than the cell layers themselves. One of the most important features of VRB battery technology is: the peak power depends on the total surface area of the cell layers, while the charge of the cell depends on the amount of electrolyte. In conventional lead-acid and nickel-metal batteries, the electrodes and electrolyte are placed together and the power and energy strongly depend on the area of the plates and the capacity of the electrolyte. This is not the case for VRB cells, however, and its electrodes and electrolyte do not have to be placed together, meaning that energy can be stored without being limited by the cell casing. Electrically, different levels of energy may be obtained for different cells or cell stacks in the battery layer by providing sufficient electrolyte, and the same voltage is not necessarily required for charging and discharging the battery layer. For example, a VRB cell may be discharged with the voltage of the series cell layers, while charging may be performed with a different voltage at another portion of the cell layers.
Studies have shown that the coulombic efficiency of vanadium batteries increases with increasing charge and discharge current, and the cell level energy decreases with increasing discharge current. More data and experiments show that the performance of the vanadium redox battery can be influenced by the charging current, the charging depth, the electrolyte temperature and the flow, and a common storage battery management system does not have the function of detecting various parameters.
