As the digital environment evolves, vast amount of data are inevitably created. That is why today is called the age of big data. Big data refers to large-scale data including numerical values, texts, and images generated in a digital environment. Big data analysis can create new values and opportunities, and companies are also highly interested in the big data analysis.
Big data is created by collecting and accumulating a large amount of data and is often produced by organizations called data centers. A data center is a facility that has thousands of servers that store various kinds of information. If a blackout occurs even for a short duration, not only do all its functions become paralyzed, but also a lot of data stored in the data center may be lost. So, in case of a power failure, we install an Uninterruptible Power Supply (UPS) that can supply emergency power to the facilities to prevent power outage.
UPS is a type of Energy Storage System (ESS) that stores the electric energy by using a battery when the power is available and supplies electricity continuously for certain duration in an emergency to prevent power failure. Because of these functions, a UPS is used in areas where power should not be cut off even for a moment, like communication facilities, financial systems, and advanced production facilities. A UPS using a lithium-ion battery has advantages such as high power, compact size, and long life.
