As one of the most revolutionary technologies, lithium batteries have changed people's lives and have been widely used in mobile phones, computers, electric vehicles and other products; however, in the past 20 years, due to the strict requirements for safety and reliability High, lithium batteries have been slow to enter the field of data centers.
Today, with the maturity of lithium battery technology, its safety and economy have been greatly improved, and the characteristics of intelligence, reliability, flexibility, and easy operation and maintenance can realize rich scene-based applications. Enter the data center space.
"Double carbon" has also become China's national policy. At the two sessions this year, carbon peaking and carbon neutrality were written into the government work report for the first time, with the goal of achieving carbon peaking in 2030 and carbon neutrality in 2060.
For the ICT industry, the focus of "Double Carbon" is the data center, because the data center has become the most important "energy-consumption" in the ICT industry and is still growing rapidly.
Compared with lead-acid batteries, lifepo4 battery has the advantages of environmental protection, high efficiency, energy saving, long life and small footprint, and is a typical green energy product. At the same time, the lifepo4 battery has the characteristics of many times of charging and discharging, so that it can also be used as an energy storage system and replace the diesel generator in the data center, which improves the "dual carbon" efficiency.
Of course, this is mainly due to the rapid progress of lithium battery technology in recent years. Technological iterations such as high-nickel solutions and large-module CTP solutions, as well as large-scale production, have made their costs continue to drop. The cost of lithium batteries has fallen by 88% over the past 10 years.
Jason, senior vice president of manly battery's global energy storage business unit, said that lifepo4 battery was first used in data centers five years ago, but the development speed of the past five years has been rapid. Today, nearly 30% of the uninterruptible power supply (UPS) projects delivered by manly battery use lifepo4 batteries.
The Curiosity rover has been in space for 10 years. Today, it still drives alone on the surface of Mars, 400 million kilometers away from us, powered by lithium batteries. Being able to work in such a harsh and complex environment for 10 years, lifepo4 battery is safe and reliable.
In fact, lifepo4 battery has not been used in data centers for a long time, the primary factor is safety concerns. Although the failure rate of lithium batteries is not very high, once deflagration occurs, it is difficult to control and will endanger the entire data center.
Today, improvements in security technology have eased these concerns. Ankolou, global product director of manly battery energy storage division, said that the safety of lithium battery systems is mainly reflected in three aspects: high-quality lithium battery cells, reliable battery management systems, and scientific fire protection and fire protection design.
The manly battery 12V 24V 48V series lithium battery solutions carry out system-level security design from the five dimensions of "cell, BMS, PACK, system architecture, and quality control system", thus ensuring the safety and reliability of product applications.
MANLY BATTERY's batteries have passed UL1642, UL1973, IEC62619, UN38.3 and other certifications, passed safety and reliability tests such as acupuncture, collision, and drop, and then passed strict factory inspections to match and apply to UPS application scenarios.
The built-in lithium battery management system BMS can monitor key parameters such as cell voltage, current, and temperature in real time, and provide double protection for abnormal conditions such as overvoltage, overcurrent, overtemperature, and short circuit. The first-class PACK in the industry has passed UL1973, TUV, UN38.3 certification and special safety certification for packaging materials, meeting the requirements of perfect functional performance testing and professional laboratory testing.
It is particularly worth mentioning that MANLY BATTERY can deeply integrate BMS and UPS software to realize full communication between lithium battery and its UPS. It can not only detect the operation status of lithium battery, but also take response measures to provide multiple protections for system operation. .
Thanks to these measures, the safety of lithium batteries has been highly recognized by users. At the same time, the lithium battery solutions provided by MANLY BATTERY also promise a 5-year warranty and a design life of more than 10 years.
Economy becomes the core advantage
"For the application of lithium batteries, I have also gone through the process of doubting and receiving surprises. Compared with the rapid application of lithium batteries in foreign data centers, the domestic promotion speed is slower, and its economy has not been recognized by everyone."— —Peng Guangxiang, Technical Director of State Grid Siji Ziguang Cloud Data.
Similar to Peng Guangxiang, many enterprise users are very concerned about the safety, economy and convenience of lithium battery technology. After security is guaranteed, economy becomes the focus of consideration.
Relevant professionals from MANLY BATTERY believe that when doing economic comparison analysis between lifepo4 battery and lead-acid battery, CAPEX should be quantitatively compared to the overall cost of the entire battery system.
He said that although the cost of a lithium battery is 4-5 times that of a lead-acid battery, its use time is long, there is no need to pay extended warranty costs, and it can achieve 100% capacity release, while a high-rate lead-acid battery can only be used for 15 minutes. Can release 42% of electricity. In addition, there is no need for battery pack protection switches and battery rack connection cables. In this way, in a 15-minute backup power system, the TCO of lithium batteries is only 10% higher than that of lead-acid batteries. The rate of coming out of the data center has increased.
The economy of the lithium battery system is also reflected in its unique energy storage application, which can be integrated with UPS to realize the deployment of the "UPS + lithium battery" energy storage system on the user side, helping enterprises to greatly reduce electricity costs and achieve carbon saving Target.
MANLY BATTERY 1000kVA UPS energy storage system can deploy lithium battery energy storage with 2MWh capacity without changing the power supply and distribution system. While supporting the power outage guarantee for 2 hours, it can also bring 85.5% per year through the peak-valley electricity price difference. Thousands of dollars in electricity savings.
As enterprise IT departments become more and more involved in business value creation, it is clear that the operation and maintenance of IT infrastructure should no longer involve them too much energy. This puts forward simple and flexible operation and maintenance requirements for all IT equipment, and the UPS system is no exception.
MANLY BATTERY related technical experts said that MANLY BATTERY not only provides products, but also provides overall solutions according to various application scenarios of enterprises to meet their business needs.
At present, MANLY BATTERY's 12V 24V 48V 60V product family includes four series of products: MANLY HPL, which provides 5-minute backup power for large data centers, MANLY HPL-P1, which provides 15-30 minutes backup power for large data centers, and MANLY HPL-P1 for small and medium-sized data centers. MANLY MPL for the computer room and MANLY SPL for edge nodes.
For large-scale data center scenarios, MANLY Adapt Li takes prefabricated integration and rapid deployment as its core selling points. The traditional lead-acid battery, battery rack, battery monitor, and power distribution protection switch are integrated into one, and the UPS power supply and distribution system is combined into a power module or container for overall delivery. The product is the system. In this way, not only cables and connection consumables are saved, but also the construction period is shortened by 60%.
As an intelligent power supply system integrated with UPS and lithium battery, it takes the powerful intelligent platform of the UPS host as the management core, realizes active early warning and active protection, and unifies the UPS intelligent interface for data analysis and upload to realize intelligent, simple and efficient management.
For small and medium-sized application scenarios, the MANLY Adapt Li solution has higher application flexibility. The UPS + lithium battery pack forms a distributed power supply solution, which reduces the load-bearing requirement on the ground of the equipment room by more than 50%, and only occupies the top/bottom of the cabinet that is usually idle. 4-6U space, improve the rate of coming out.
It is precisely because of the increasing maturity of lithium battery technology and the introduction of scenario-based intelligent solutions by major manufacturers that lithium batteries are more and more widely used in data centers.
Large cloud service providers including Microsoft and Amazon have also introduced lithium batteries into their data center designs, forming an obvious trend of replacing lead-acid batteries.
In the future, this trend will accelerate.
