Lithium batteries have been commercialized in various applications for more than 20 years. So why are they not widely used in data center UPS? the answer is like all other applications, lithium batteries can not provide UPS suppliers with a reasonable balance between price, energy density, power, safety and reliability in UPS application. But in the past 10 years, improvements in lithium-ion chemistry and technology have provided UPS suppliers with viable solutions. These improvements are largely due to the development of the electric vehicle industry.

The price advantage of lithium iron phosphate batteries will gradually become prominent, and energy storage will be an important potential market for lithium iron phosphate in the future. It is reported that compared with the NCM, lithium iron phosphate has obvious advantages in terms of service life, safety, and fast charging and discharging, and is more suitable for the energy storage market. In the UPS uninterruptible power supply system, the backup battery pack is the last line from the power outage for the entire power supply system, and it is also the focus and difficulty of power supply maintenance. In the system interruption accident, the fault caused by the battery pack accounts for a larger proportion, therefore, people will be more cautious about the battery changes in backup battery technology.

  1. Low energy density, but with high weight and a big size.
  2. The charging and discharging efficiency is low, the charging and discharging efficiency is about 92%, and the charging and discharging efficiency will even decrease after a period of use.
  3. The valve-regulated lead-acid battery has a short life span, with a design life span of 5-8 years, and most practical use is 3 to 5 years.
  4. The operating environment is limited. When the temperature exceeds 25 degrees, the battery life will be reduced by half when the ambient temperature increases by 7 to 10 degrees.
  5. The storage battery uses a large amount of lead, which is likely to cause serious pollution to the environment during mining, processing and use.
Application of Lithium Iron Phosphate Battery in UPS Power Supply System

Current in the mature energy storage applications, lithium iron phosphate battery distributed energy storage power system have long been widely used in communication base stations, user-side peak shaving and valley filling, off-grid power stations, microgrids, rail transit, UPS and even household energy storage. It is estimated that by 2020, the cumulative installed capacity of China’s energy storage market will exceed 50GW, which is expected to bring a significant increase in the demand for lithium iron phosphate batteries.

5G is facing a unfavorable development factor, the power consumption of 5G base stations need a several times of power than the 4G base stations, that’s means great demands expansion on the power system at the same time. Currently, lithium batteries are mainly used in 4G small base stations, large energy storage base stations are still dominated by lead-acid batteries. As the power of 5G equipment is greater than 4G, this correspondingly means that almost all of the Network operator company’ current Data center rooms must modify the power supply system to ensure power supply, including switching power supplies, batteries, and power cords replacement.

Due to pollution and performance, lead-acid batteries are gradually unable to meet the requirements of communication base stations and will be gradually eliminated. But new problems have initially appeared during choosing alternative energy sources. In the fierce competition and technological development, Network operator company are constantly pursuing low costs. Purchasing low-cost lithium batteries is the most direct and effective way to reduce costs.

After upgrading to 5G, the performance of the lithium iron phosphate battery in the base station system will greatly affect the stability of the network signal, which is related to the user’s usage and experience, so Network operator company will have higher requirements for battery consistency and stability. In view of the characteristics of lithium iron phosphate batteries, when the UPS power supply system is set up, it is only need to adjust the charging voltage of the UPS to meet the the LiFePO4 battery pack. Because even the lithium battery is in a charging state for a long time, the battery characteristics is not easy to change due to its own BMS balance protection function.
