The application range of UPS lithium iron phosphate batteries in energy storage and communication base stations has been further expanded. The emergence of lithium batteries as a new energy source is undoubtedly sending charcoal in the snow and solving the problem of natural resources. The battery used in the UPS power supply is a lithium battery, mainly because the lithium battery is not excellent in terms of storage power and performance, so in the UPS power supply, the lithium iron phosphate battery has also become the best choice. UPS energy storage lithium iron phosphate battery application schemes in various industries① Solar photovoltaic power station Solar energy is a green, pollution-free and clean energy, which has important application value in the field of photovoltaic power generation. High-performance energy storage UPS lithium iron phosphate batteries are crucial to the development of the photovoltaic industry. Compared with lead-acid batteries, lithium iron phosphate batteries have the advantages of high specific energy, high energy storage efficiency, long cycle life, and low cost of use. The use of lithium batteries as energy storage power sources can increase the energy efficiency to about 90%, so it is very suitable for use as a new energy storage device. Its main function is to store the electrical energy of the photovoltaic power generation system, and to supply power to the load when the amount of sunlight is insufficient, at night and in emergency situations. The integrated monitoring and management system of solar photovoltaic power station is composed of communication management machine and monitoring center. The communication management machine collects equipment data such as inverters, combiner boxes, AC and DC grid-connected power distribution cabinets, integrated self-protection, and electric energy. Field intelligent equipment is networked with data collectors through various buses, optical fiber networks, and other methods. The monitoring center operates a monitoring integrated management system, responsible for the centralized monitoring of on-site intelligent equipment and the configuration, management and maintenance of the system. In terms of photovoltaic energy storage efficiency, UPS lithium iron phosphate batteries have obvious advantages. ②Communication base station power supply Public mobile communication base station is a form of radio station, which refers to a radio transceiver station that transmits information to mobile phone terminals through a mobile communication switching center in a limited radio coverage area. The construction of mobile communication base stations has become an indispensable part of my country's communication industry, and base stations are very important equipment for communication. The backup power supply based on 48V lithium iron phosphate battery can be widely used in indoor and blind area coverage, second and third types of mains areas, short-term backup power and other scenarios that require high power weight, volume, cycle life, and magnification. Energy storage lithium iron phosphate battery UPS is a reliable energy storage power supply as a backup power supply in communication base stations. In the medium and long term, the promotion of the use of integrated lithium iron phosphate batteries in outdoor communication base stations can reduce costs and increase efficiency. Through exchanges and understanding, similar situations also exist in other areas of the province. It can be seen that the demand for replacing lead-acid batteries with lithium iron phosphate batteries in outdoor stations is particularly urgent. ③In order to promote the optimization and upgrading of the energy industry and achieve clean and low-carbon development, energy storage power stations have been vigorously developing clean energy in recent years. Wind power and photovoltaics have achieved leapfrog development, and the proportion of new energy installed capacity is increasing. However, with the rapid development of clean energy, the grid connection of volatility and intermittent new energy has brought adverse effects on the power grid in terms of regulation and operation, safety control, etc., which greatly restricts the effective use of clean energy. The lithium iron phosphate battery UPS energy storage power station can be combined with distributed/centralized new energy power generation. It is one of the effective ways to solve the problem of new energy power generation and grid connection. It will increase with the increasing scale of new energy power generation and battery energy storage technology. The continuous development of China has become a major key technology supporting my country’s clean energy development strategy. Energy storage lithium iron phosphate batteries can increase the energy storage efficiency of photovoltaic systems to 95%, far exceeding 70-80% of traditional lead-acid batteries, and have a service life of 2000 charge and discharge. Lithium batteries are expected to increase the efficiency of solar power systems and help reduce their installation and maintenance costs. ④Data center In recent years, with the explosive growth of mobile Internet, Internet of Things, cloud computing and other data business needs and the rapid development of IT technology, data center is developing into a strategically significant emerging industry, becoming a new generation of information industry. An important part of. Under the premise of rapid improvement of electronic information and manufacturing technology, the construction scale and equipment density of data center computer rooms have achieved considerable growth. With the maturity and improvement of UPS lithium battery energy storage system technology and the increasing cost optimization, data center UPS will quickly complete the conversion from lead-acid batteries to lithium batteries. In the future, lithium batteries will not only serve as UPS short-term backup delays, for example, with the help of UPS+ Lithium batteries can achieve profit from peak shaving and valley filling and the price difference between peak and valley electricity, and it is not even ruled out that partial replacement of diesel generator sets by energy storage containers is not ruled out. In China, the trend of UPS switching to lithium batteries will become even more rapid. The lithium battery industry uses highly automated production lines, and production capacity determines the cost. This is a near-winner-take-all industry. As the world’s largest producer of lithium batteries, various manufacturers have been vigorously expanding production in recent years, but the result is a serious overcapacity in the entire industry. As the Chinese government’s subsidies for electric vehicles are gradually shrinking, the lithium battery industry is in urgent need Exploring new application growth points, such as wind and solar energy storage, grid frequency and peak regulation, communication power supply, UPS backup battery, etc. will become the new favorite of the lithium battery market. It is inevitable for the entire UPS industry to replace lead-acid batteries with energy storage lithium iron phosphate batteries. It is only a matter of time.
