Application analysis of new lithium batteries in data centers

The application of new lithium batteries in data centers In recent years, due to space constraints and the need for more efficient operations in data centers, increasing their power density has been an important goal; efficient available space is also an important consideration. With the improvement of the mains power supply environment and the highly redundant design of the data center power supply system, the lead-acid battery for UPS is rarely used for discharge purposes. Together with the heavy weight and high maintenance cost, the maintenance cost is greatly reduced. increase. Based on this, the industry began to explore the use of lithium batteries. To be sure, lithium batteries are increasing the bet on UPS power supply industry technology. Lithium battery UPS may have a great impact on the future data center industry. Because more and more companies hope to adopt an open computing-based architecture, they will specify the use of lithium batteries as the power supply unit of the server power supply in the rack. ●Volume: In terms of volume, usually the upper layer of a multi-story data center facility needs to be reinforced with steel beams to support heavier lead-acid battery packs. Because lithium batteries are lighter in weight and occupy less space, they are more suitable for high-rise data centers. Data center operators can place lithium battery cabinets at a higher position without the need to reinforce the floor. ●Small footprint: Lithium batteries have a small footprint, occupying only one third of the space of lead-acid batteries, making them very suitable for use in modular data centers. Small lithium batteries can reduce the footprint of the uninterruptible power supply system by 50-80%. This kind of battery charges and discharges itself at a faster speed for a shorter time, and plays an important role in the event of frequent interruptions. Because the lithium battery is lighter and more flexible, it can reduce the total weight of the modular data center, making it easier to transport, easier to install, and lower in cost. ●BMS battery management system: Lithium battery combined with advanced battery monitoring system (BMS) can provide clear and specific information about battery running time and health status. ●Life span: The life span of lead-acid batteries is very short, only three to six years. The working life of the lithium battery is 10-15 years, and the longer shelf life greatly reduces the cost of battery replacement and maintenance burden. According to the difference in chemistry, technology and temperature, lithium batteries can be charged 5000 times without maintenance, while the average number of charging times of lead-acid batteries is 700 times. ●Safe and reliable: The system adopts high-safety, long-life lithium iron phosphate batteries, and adopts a four-level system protection method. The system charge and discharge circuits are managed separately, and no gap discharge ensures reliable power supply.
