Data center and UPS battery applications

Data Center Overview:
Data centers are global collaborative networks of specialized equipment used to transmit, accelerate, display, compute, and store data information on the Internet infrastructure. Most electronic components in data centers are driven by low DC power supplies.
The emergence of data centers has led people from a quantitative, structured world to an uncertain, unstructured world. It will gradually become part of modern social infrastructure such as transportation and network communications, and will have a positive impact on many industries. However, the development of data centers cannot be based solely on experience, but must be truly combined with practice to make data centers truly valuable and promote rapid social change.
The following mainly introduces the application of UPS batteries in data centers
UPS Overview:
UPS, or uninterruptible power supply, is an uninterruptible power supply with energy storage device. It is mainly used to provide uninterruptible power supply for some equipment with high requirements on power supply stability.
When the mains input is normal, the UPS stabilizes the mains and supplies power to the load. At this time, the UPS is an AC voltage stabilizer and also charges the battery inside the machine; when the mains is interrupted (power outage), the UPS immediately switches the DC power of the battery to the load through inverter switching, and continues to provide 220V or 380V AC power to the load, so that the load can maintain normal operation and protect the load software and hardware from damage. UPS devices usually provide overvoltage or undervoltage protection.

In data centers, a parallel redundant UPS system consisting of a single double-conversion UPS is generally used. When the data center load is powered by dual power supplies, a parallel redundant UPS is used to form a dual-bus UPS power supply system.
The following takes the lithium battery UPS of Kehua Data Center as an example.
Lithium battery UPS features:
The lithium battery UPS system, combined with the characteristics of lithium iron phosphate batteries such as high energy density, small footprint, long service life, high safety performance, and convenient operation and maintenance, can provide high-quality power supply guarantee for data centers, IT computers, computer rooms, communications, IT and other fields. The main key loads.
Characteristics of lithium batteries
The number of charge and discharge cycles can reach 5,000 times, and the service life can reach 10 years. The BMS battery management system has complete protection functions (short circuit, overcurrent, overcharge, overdischarge, overtemperature, etc.)
The lithium battery UPS system has three levels of protection control. UPS and BMS realize full monitoring of the dual lithium battery backup system
The PACK module is standardized and can be freely combined. The volume and weight are 1/3 of the lead-acid battery, which is more suitable for application scenarios with limited space.
In addition to lithium-ion UPS used in data centers, backup and online UPS are also commonly used, mainly in government, education, finance, communications, insurance, transportation, taxation, securities and other fields. These fields still mainly use lead-acid batteries for energy storage applications
