Lithium battery UPS energy storage system will be the development trend of power supply and distribution in the future. The power supply and distribution system is the lifeline of the data center. To build a good data center computer room, you must first have a high-quality power supply and distribution system. More and more power supply and distribution systems such as lithium battery UPS energy storage power supply are being adopted by the industry. The editor believes that the lithium battery power supply and distribution system will be the development trend of UPS power supply in the next 10 years. The drive of data center technology and market demand has brought about changes in power demand, cooling technology, and room space. Taking power demand as an example, the current data center battery technology is dominated by lead-acid batteries, and in the future, lithium batteries will become an opportunity for growth. For example, the lithium battery UPS energy storage system has better coordination with the grid to reduce electricity costs. Regarding lithium battery, we have adopted a large number of lithium battery UPS power solutions in communication base stations. The application of lithium battery solutions in the field of data centers or UPS backup power, the editor of Energy Storage Electric believes that it will become a trend in the future, and there will be more data center applications in developed areas. In the IT wave, many developed countries consider lithium battery solutions, mainly due to the following reasons: First, lithium battery itself brings a sharp reduction in floor space. As we all know, the data center covers a large area. In cities such as London, Singapore, and Hong Kong, where the storage battery takes up such a large area, it will affect the efficiency. In terms of the overall investment income, the area needs to be greatly reduced. The second is that the battery has the ability to charge and discharge multiple times. This feature will produce economic benefits, such as peak-shaving and valley-filling of peak and valley electricity prices. The third is that there is a cooperative power supply mode. When the load peaks, if the grid power supply is not enough, the lithium battery can be used for coordinated power supply, reducing the city power input and reducing the initial investment. Fourth, the life cycle of lithium batteries is longer. From the perspective of life cycle costs, the cost of lithium batteries is better than that of batteries due to the lower replacement frequency. In the future, the price of lithium will continue to fall, while the cost of lead-acid is rising, so we are very optimistic about the application of lithium batteries. Cuneng Electric actively follows the pace of market development and continuously develops new lithium battery UPS products. Lithium battery UPS power supply is a new product with small size, super capacity and high efficiency independently researched and developed by Energy Electric Technology in response to the growing communication network requirements. The product uses a more efficient lithium iron phosphate battery as a power supply guarantee; the appearance design uses the most widely used 19-inch standard rack-mounted chassis. Meet the user's integrated installation requirements; the rack-mounted lithium battery UPS power supply adopts advanced digital control technology, integrated AC and DC dual output, DC current limit, peak surge absorption, comprehensive automatic protection, unattended, intelligent Multiple functions such as remote monitoring are integrated. Products are widely used in communications, electric power, public security, fire protection, radio and television, finance, military, Internet and other industries. The matching and integrated equipment includes: communication base stations, integrated power distribution cabinets, data centers, modular integrated products, etc. The future market is a subdivided market. Various power supplies depend on different power supply requirements. The ideal idea is to reduce the use of tower UPS in data center construction in the future and replace it with lithium battery UPS to improve maintainability. Performance, thereby providing overall system availability. UPS switching to lithium batteries will be the future development trend. With the advantages of environmental protection, safety, light weight, small size, and wide temperature range of lithium batteries, more and more UPS power supply manufacturers are replacing traditional batteries with lithium batteries. In the future, the trend of UPS switching to lithium batteries will be even more rapid. 10% of data centers have adopted lithium battery UPS power supplies as energy storage equipment, which shows a very good trend. In recent years, large domestic and foreign companies, including Vision Group, Shuangdeng Group, Emerson, Schneider Electric, and Eaton Power, have begun to deploy lithium battery UPS. ① Vision: In recent years, Vision Technology has developed diversified products. Since entering the UPS industry for 20 years, Vision Technology has independently developed a series of high-quality UPS battery product power supply solutions, and at the same time entered into lithium battery solutions. Vision's lithium battery UPS solution adopts Vision's unique technology and is specially designed for low-voltage, low-power and long-running applications. It has excellent performance in terms of safety, service life, and backup time. And it can be charged with standard lead-acid battery charging methods. ②Shuangdeng Group: At the end of 2015, Shuangdeng Group launched a lithium-ion battery for communication. The positive electrode of the battery is made of lithium iron phosphate (LiFePO4) material, which has good safety performance and long cycle life; the battery system uses a high-performance dedicated BMS battery management module , The BMS has protection functions such as voltage, current, and temperature, and uses the system to communicate well with the host; the monitoring unit automatically measures the battery's charge and discharge current, charge and discharge voltage, cell surface temperature and ambient temperature. ③Schneider Electric: In 2016, Schneider Electric announced that it has deployed four medium and high-power UPS product series such as Galaxy7000, GalaxyVM, GalaxyVX, and SymmetraMW in the application of lithium battery in data centers. It said that the new UPS products that will be launched after 2017 will be fully compatible. Lithium battery solution. It can be seen that many large enterprises at home and abroad have begun to deploy the lithium battery UPS market. Although lithium batteries are currently 2-3 times more expensive than lead batteries, with the continuous development of lithium battery UPS technology, its cost will also be significantly increased. Decline, the price difference between the two batteries is currently shrinking at a rate of 20% per year. It is expected that within two to three years, the price of lithium batteries will gradually converge with that of lead batteries. With the development of data centers and power valleys, UPS will reuse lithium batteries in the future. More and more UPS devices on the market today choose lithium batteries. This is a good thing for the industry and an irreversible trend.
