　　Advantages of using lithium battery UPS as power supply management system. Lithium battery UPS is a new type of lithium battery energy storage power supply. Compared with traditional UPS lead-acid batteries, it has the advantages of environmental protection, safety, long service life, high temperature resistance, and no memory effect. Management systems that use lithium batteries as UPS power supplies are beginning to be adopted by customers. So, what are the advantages of lithium battery UPS management system? Let’s follow the steps to discuss.

　　1. Advantages of using lithium battery UPS as power supply management system

　　Today, for UPS battery-powered systems, the initial capital expenditure of using lithium-ion batteries is only 1.4 times that of lead-acid batteries, but the total cost of ownership (TCO) of using lithium-ion batteries can save 10%-30% over 10 years. The advantages are as follows:

　　①Light weight

　　Lithium batteries are about one-third lighter than lead-acid batteries. This saves data center construction costs because the floor does not need to be reinforced to bear additional weight. It also saves on shipping costs because more lithium-ion batteries can be shipped for the same cost compared to lead-acid UPS batteries.

　　②Long life

　　The cycle life of lead-acid batteries is about 300 times. For lithium iron phosphate batteries, when charged and discharged at room temperature at 1C, the capacity of the monomer is still greater than 80% after 2,000 cycles, and the 3C cycle life reaches more than 800 times.

　　③Quick charging

　　Lithium battery UPS can charge and discharge quickly at a high current of 2C. The battery can be fully charged within 40 minutes at 1.5C with a special charger, and the starting current can reach 2C. However, lead-acid batteries currently do not have this performance.

　　④Higher energy density

　　Lithium battery UPS has higher energy density (Wh/kg, or watt hours per kilogram) and power density. The energy density is 3 to 4 times that of lead-acid batteries, 2.5 times that of nickel-cadmium batteries, and 1.8 times that of nickel-metal hydride batteries. times.

　　⑤High temperature resistance

　　Lithium battery packs can operate at temperatures of 86°F (30°C), which is nearly 10°C hotter than lead-acid batteries. The thermal peak of lithium iron phosphate battery UPS can reach 350~500℃, and the operating temperature range is wide (-20~+75℃).

　　⑥ Reduce maintenance and reduce costs

　　Lithium batteries are equipped with a built-in battery management system (BMS) that provides monitoring and maintenance functions such as automatic status, fault monitoring, cell balancing, power optimization and external communication. Lithium battery UPS can reduce labor and maintenance costs and significantly reduce the risk of battery pack failure.

　　⑦Environmentally friendly and pollution-free

　　Lithium iron phosphate material does not contain any heavy metals and rare metals, is non-toxic, has no pollution in production and use, complies with European RoHS regulations, and is a green battery. However, there is a large amount of lead in lead-acid batteries. If they are not handled properly after they are discarded, they will still cause secondary pollution to the environment.

　　⑧No memory effect

　　No matter what state the lithium iron phosphate battery pack is in, it can be used at any time without having to discharge it completely before charging.

　　2. Application cases of UPS lithium batteries in banking systems:

　　The Caohejing Disaster Recovery Center of the Bank of Communications carries out the design, development, construction, operation and maintenance of large-capacity UPS lithium battery energy storage systems, thereby taking the first step in combining bank big data with lithium battery energy storage technology. In July 2016, a complete set of lithium battery UPS energy storage system was officially built in Caohejing Data Center and successfully connected to the grid for the first time, officially entering the demonstration application stage. After half a year of grid-connected operation, Aerospace Power and users jointly conducted an actual on-site discharge test, and all performance of the system reached the expected goals.

　　The successful application of lithium battery UPS energy storage system is also an important practice for Aerospace Power to promote the development of the "four new economies" and realize the transformation from a "battery manufacturer" to a "power system solution provider and complete equipment mainstream supplier". It is reported that if lithium battery energy storage systems are fully promoted and applied in the banking industry, the output value can reach billions of yuan, and it is expected to become a new growth highlight.

　　3. Future prediction and outlook of UPS lithium battery management system

　　For large data centers, the amount saved by using UPS lithium battery systems will be huge, so lithium battery power supply systems will gradually increase in the enterprise sector. Lithium-ion chemistry also continues to improve. New solutions and technologies will emerge over time, and the price of lithium batteries will fall further.

　　It is inevitable for lithium batteries to replace lead-acid batteries. From a long-term use perspective, lithium battery UPS can save 10% or more. Currently, lithium batteries in foreign countries have begun to replace lead-acid batteries in UPS and have begun to be accepted by more companies. In some countries ( For example, in South Korea, the process of replacing lead-acid batteries with lithium batteries is very fast, and the proportion of lithium batteries has reached as high as 30%. There are even all-lithium battery UPS systems like Shinhan Bank.
