An uninterruptible power supply (UPS) is one of the most critical power components in a data center. However, the role of batteries used in UPS power supplies is often overlooked.
If the mains of the data center fails, the battery of the UPS power supply must immediately take over and use its stored energy to support the workload until the mains is restored, the diesel generator can be started or the data center can be shut down safely.
Therefore, UPS power batteries are essential for data centers. The following highlights the key issues to consider when selecting battery technology for UPS power.
Advantages and disadvantages of UPS batteries
UPS batteries are a major contributor to these priorities, as data center managers need energy-efficient technologies to ensure business continuity, extend operating life, and reduce total cost of ownership (TCO).
Users need to choose which one has the expected total cost of ownership (TCO), which has a direct impact on energy efficiency and charging rate. Traditional lead-acid batteries have replaced more than 90% of the UPS market, but interest in lithium-ion technology is increasing.
【This is because lithium-ion batteries have a smaller size and excellent fast charging capabilities. And, the maintenance demand of the lithium-ion battery is low and needs a long time. However, they also require a dedicated charging system, battery management to ensure safe operation, and not easy recycling.
Therefore, it is worth considering alternatives to traditional lead-acid and lithium-ion batteries, such as thin-plate pure lead (TPPL) batteries, which offer similar performance advantages to lithium-ion batteries and have advantages over traditional glass fiber segments (AGM ) Higher energy efficiency of batteries.
