With the advancement of supercapacitor energy storage technology, supercapacitor energy storage has become possible. Therefore, it has attracted people's attention to this industry. So, how much do friends know about supercapacitor energy storage? Next, we will share relevant content with you. Introduction As early as August 2006, Shanghai No. 11 supercapacitor bus was put into operation. It was the only pure electric bus in the world that had passed the test of large-scale and long-term commercial operation. What characteristics does supercapacitor have that make it popular among users? Technical Principles We take electric double layer capacitors as an example to introduce the working principle of supercapacitors. Electric double layer supercapacitor is a new type of energy storage device that relies on polarized electrolyte to store electrical energy. Its principle structure is shown in the figure. In a double layer capacitor, electrical energy is stored in an electrostatic field between the electrodes and the ions of the electrolyte. When the electrode is charged, the surface charge of the electrode in the idealized electrode state will attract the opposite ions in the surrounding electrolyte solution, causing these ions to attach to the electrode surface to form a double charge layer, forming an electric double layer capacitance. Compared with traditional capacitors, supercapacitors have a much larger area for storing charges and a much smaller distance at which charges are isolated. Therefore, the capacitance of a supercapacitor unit can be as high as several to tens of thousands of farads. Due to the special process, the equivalent resistance of the supercapacitor is very low, the capacitance is large and the internal resistance is small. The supercapacitor can have a very high peak current, so it has a very high specific power, up to 50 to 100 times that of the battery, which can reach about 10kW/kg. This feature makes the supercapacitor very suitable for short-term high-power applications. Application scenarios Public transportation/electric vehicles The composite power system composed of supercapacitors and other energy storage components takes into account the advantages of the high specific energy of other energy storage components and the high specific power of supercapacitors, and can better meet the needs of starting and accelerating electric vehicles. performance requirements and can improve the braking energy recovery efficiency of electric vehicles. Increase driving range. At present, supercapacitors can be combined with batteries, fuel cells, flywheel batteries, etc. to form composite power systems. The use of supercapacitor-battery composite power supply systems in pure electric vehicles and hybrid electric vehicles will be one of the important directions for future development in the field of electric vehicles. Wind power Wind power is currently the fastest growing renewable energy power generation technology. However, wind energy is a randomly changing energy source, and changes in wind speed will cause fluctuations in the output power of wind turbines, which will affect the power quality of the power grid. Therefore, studying the output power regulation of grid-connected wind farms has become an important issue in wind power generation technology. Additional energy storage equipment can not only regulate reactive power, stabilize wind farm bus voltage, but also regulate active power within a wide range, which is a current research hotspot. With the development of manufacturing technology, the energy density of supercapacitors has been greatly improved, and it has entered the commercial application stage in some short-term power energy storage applications. The use of supercapacitors to store energy and stabilize wind power fluctuations in important frequency bands of wind farm output power has good application prospects. During microgrid/grid microgrid operation, when the total power generation capacity is less than the total load demand and at the same time it enters island operation due to an external fault, the secondary load must be removed in order to protect the important load. If the external fault is a transient fault, in a short time The internal microgrid will be reconnected to the main network due to the disappearance of the instantaneous fault, and the secondary load will be restarted. From the perspective of power supply stability and economy, it is unfavorable to secondary loads. Therefore, after an external fault, supercapacitors can be used to provide short-term power deficits to the microgrid operating in an island, maintaining all loads and waiting for the fault to be repaired. Building/Elevator Energy Saving The energy consumption of buildings in my country accounts for about 28% of the country's total energy consumption. Among them, the electricity consumption of elevators is second only to air conditioning, and much higher than the electricity consumption of lighting, water supply, etc. The energy consumption of elevators has attracted great attention from the industry, so energy saving of elevators has very important practical significance. Therefore, research and development of high-efficiency motor driving systems is the key to energy saving in elevators. Energy feedback energy-saving elevators have relatively mature technology, but due to price factors and impact on the power grid, promotion is still difficult. The supercapacitor is directly connected to the DC bus to absorb the feedback energy. The supercapacitor is directly connected to the DC bus of the frequency converter. Supercapacitors have good application effects and advantages in high-power electrical and electronic products, especially elevator products, and their application prospects are unlimited. After reading the above content, what do you gain? It can be said that the advantages of supercapacitor energy storage are very obvious. In the future, it will definitely have very good development prospects, and everyone can also seize the business opportunities of this development.
