Advantages of lithium battery UPS as a power supply management system

　　1. Advantages of using lithium battery UPS as power supply management system Today, for UPS battery power supply 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 of using lithium-ion batteries in 10 years (TCO) can save 10%-30%. The advantages are as follows: ①Lightweight 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 battery 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. ③ Fast 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-hour per kilogram) and power density. The energy density is 3 to 4 times that of lead-acid batteries and 2.5 times that of nickel-cadmium batteries. It is 1.8 times that of NiMH batteries. ⑤High temperature resistant lithium battery pack can operate at a temperature of 86°F (30°C), which is nearly 10°C higher 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), which can provide monitoring and maintenance functions such as automatic status, fault monitoring, battery balancing, power optimization and external communication. Lithium battery UPS can reduce labor and maintenance costs and significantly reduce the risk of battery pack failure. ⑦ Environmentally 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. ⑧The lithium iron phosphate battery pack with no memory effect can be used at any time no matter what state it is in. There is no need to discharge it completely before charging it.
