What are the characteristics of the intelligent lithium-ion energy storage system compared with the ordinary lead-acid battery energy storage system? In terms of energy storage, it is easy to think of batteries; outdoor power supplies; mobile power supplies; power banks, etc., but the existing battery technology is very It is difficult to meet the requirements of grid-level energy storage. In fact, the energy storage market has huge potential. Lithium-ion battery intelligent storage and control system is suitable for various solar street lights, solar building lighting, mobile communications, small power generation systems, rooftop power stations and other fields. What are the characteristics of the intelligent lithium-ion energy storage system compared with the ordinary lead-acid battery energy storage system? Different from the ordinary energy storage system, the intelligent energy storage system integrates communication technology, power electronics technology, sensor technology, high-density technology, and high efficiency Heat dissipation technology, AI technology, cloud technology and lithium-ion battery technology. As a key component of the energy storage system, traditional lead-acid batteries are bulky and heavy, and the limited computer room and site space can no longer accommodate so many batteries. In energy storage systems, it is a general trend to replace lead-acid batteries with lithium-ion batteries with smaller size, lighter weight, higher energy density, longer life, and better performance. The basic lithium-ion battery function with better performance adopts the industry's highest density design, small size, light weight, 150Ah capacity only 3.6U, one cabinet can hold 600Ah, can replace old lead-acid batteries in situ, no need to add cabinets, solve the problem The telecommunications industry has long faced headaches such as difficulty in obtaining sites, high site rents, and slow construction progress. Based on technologies such as sensing, communication, AI and cloud, it can test and manage voltage, current, temperature and balance functions in real time, realize overvoltage/undervoltage, overcurrent and high/low temperature automatic protection and high-precision balance, which improves battery usage Efficiency, reducing operation and maintenance costs, but also to ensure 100% safe use. Even when an extreme external cause causes a fire, the intelligent lithium-ion battery can extinguish 100% self-extinguishing, meeting the extreme safety requirements of the communication equipment room. In-site collaboration: Smart boost, smart mix and match, and smart anti-theft. The voltage of the traditional energy storage system itself will gradually drop as the battery discharges, and even voltage dips will occur, which brings greater challenges to the stability of 5G power supply. The intelligent energy storage system is linked to the 5G power supply. The discharge capacity of a 100Ah intelligent lithium-ion battery is equivalent to a 200Ah ordinary lithium-ion battery or a lead-acid battery. It supports a 57V constant voltage output without the use of thick cables. It releases 100% of the power and can be increased. The power supply distance of the site reduces battery investment. Aiming at the problem of bias current when new and old batteries or different types of batteries are mixed and matched, the intelligent energy storage system can realize intelligent coordination between different battery packs and power sources, and perform intelligent voltage regulation and current limiting allocation management on the bias current and circulating current between battery packs, and realize intelligent parallel operation without loss of output power . Taking a typical 8kW power consumption 1h backup power scenario as an example, the ordinary energy storage system in the industry needs to be equipped with 4 sets of 100Ah lead-acid or lithium ion batteries, while the smart energy storage system only needs to be equipped with 2 sets of 100Ah smart lithium ion batteries, saving 2 sets of batteries and 1 cabinet, which reduces the area and site rent. The intelligent energy storage system can also automatically adapt to the voltage of different battery packs, avoiding the intelligent mix and match of the multiplier, lead-acid batteries, new and old lithium-ion batteries, and maximize the use of existing batteries, which not only protects assets, but also reduces 5G evolution points. Step investment. At the same time, in response to the frequent theft of batteries, the intelligent energy storage system can realize online intelligent software lock anti-theft, offline intelligent displacement lock anti-theft and GPS positioning tracking through intelligent collaboration with power supply and network management, and minimize the loss of theft. Inter-station/station-network collaboration: intelligent peak shaving, intelligent peak shifting, and fine management of the entire network. When the load peaks, the intelligent energy storage system participates in the load power supply to achieve 'smart peak shaving, Reduce investment and speed up 5G deployment. With the intelligent coordination of smart network management and power grids and the high cycle performance of smart lithium-ion batteries, it can also be charged during periods of low electricity prices and discharged during periods of high electricity prices through 'smart peak shiftingFacing the future, the energy storage system equipped with intelligent lithium-ion battery and the network management intelligent collaboration can realize the visibility, manageability and control of the energy storage system of the whole network; through big data and AI analysis and prediction, forward-looking operation and maintenance and inter-station can be realized Battery resources complement each other, thereby reducing operation and maintenance costs and reducing resource waste. The downstream applications of lithium-ion energy storage have blossomed in many ways. Specifically: ①With the further advancement of the power system reform, the installed capacity of lithium-ion energy storage is expected to continue to increase rapidly over the past two years. Total 7.57GW/7.1GWh. ②The cost of new energy power generation is further reduced, and its penetration rate in the power system will continue to increase. It is estimated that the cumulative installed capacity of lithium-ion energy storage will reach 9.23GW/27.69GWh in 2024. ③In 2020, my country will enter the peak of 5G construction. It is estimated that the installed capacity of lithium-ion energy storage will reach 12.48GW/43.68GWh in 2025. Considering only the grid side peaking and frequency modulation, the new energy side, and the 5G base station side, the total installed demand for lithium-ion energy storage will reach 28.41GW/75.43GWh in 2024. If calculated at 0.5 yuan/wh, the market space is expected to reach 377 in 2024 Billion, which is about 20 times more than the current market size. Summary: The global new energy and smart grid industries have surged, providing a huge market space for the energy storage battery industry. The lithium-ion battery industry already has a complete industrial chain in my country. With the advancement of technology in the future, lithium-ion batteries are definitely only a transitional product, and there will be better ways to store energy.
