Data centers, energy storage, system integration, and UPS power go with "lithium". The new generation of power supply and distribution solutions for lithium batteries are applied in multiple scenarios such as photovoltaics, energy storage, charging piles, and system power protection. The professional load provides better power supply and distribution solutions.
Data center and "lithium" peer
With the standardization of data center construction, the stability of the direct supply of mains power is already very high, and the redundancy of the power supply system of the data center itself has been fully considered in the design. In the data center computer room project, many customers have begun to configure ultra-high-power UPS with lithium battery solutions, and complete the design scheme, system debugging, engineering implementation and other work in a relatively short period of time, and realize the rapid and reliable implementation of the project.
The efficiency of energy storage lithium battery UPS is as high as 98%, which is 5% to 10% higher than that of traditional online UPS, which greatly reduces the operating cost. Taking a 3MW data center as an example, every 1% increase in power supply efficiency can save more than 1 million yuan in electricity bills a year. Lithium batteries enter the data center to supply power for IT equipment such as servers and storage. Multiple forces such as OCP, UPS manufacturers and some start-ups are working together to promote the process of lithium batteries entering the data center.
Lithium-ion batteries are lightweight and small, and can save 50% space compared to lead-acid batteries, allowing data centers to accommodate more IT equipment and reduce cooling requirements. At the same time, the lighter weight can reduce the requirements for the load-bearing capacity of the floor, thereby reducing the construction or renovation cost of the equipment room.
UPS power supply goes with "lithium"
The solution of UPS power supply supporting lithium battery replaces the lead-acid battery solution, which reduces the area of the system and the operating cost of the system. In recent years, Suneng Electric has actively deployed the lithium battery power supply and distribution market. Its main product series include new energy energy storage, data center power supply and distribution, high-end UPS, etc., which can be equipped with lithium batteries, which can not only meet the application of data centers, communications and other industries It can also calmly meet the strict requirements of high reliability and high safety for power supply and distribution systems in industrial, rail transit, government, medical and other application scenarios.
Lithium battery solutions have become new friends of UPS users. Lithium batteries have the advantages of high energy density, small size, light weight, long life, and wide operating temperature range. Enterprises also provide reliable lithium battery UPS solutions as a new choice for customers.
Photovoltaic energy storage goes with "lithium"
Most of the previous photovoltaic systems also used lead-acid batteries as energy storage devices, but in comparison, lithium iron phosphate battery replacement can give full play to its advantages, including improving energy storage efficiency, prolonging service life, and reducing unit costs. This type of lithium battery is used as an energy storage device, which can increase the energy efficiency to 95%, far exceeding 80% of traditional lead-acid batteries, and has a service life of 1600 times of charge and discharge.
"Internet +" will bring major changes to the energy storage lithium battery industry. As a state-owned large-scale comprehensive service enterprise for communication infrastructure, the Tower Company has 1.9 million base stations and has a large demand for backup power. Stop the purchase of lead-acid batteries, and uniformly purchase batteries for cascade utilization.
In 2020, China will vigorously develop 5G and infrastructure projects. Under the two-way drive, 5G base stations will be an inevitable trend to vigorously promote in 2020. With China Mobile launching the bidding for base station lithium batteries, the demand for base stations will be further released in the future. GGII It is conservatively estimated that the demand for newly built and renovated 5G base stations in 2020 will reach 10GWh, and the penetration rate of energy storage lithium batteries will further accelerate.
System integration goes with "lithium"
The development of the power lithium battery industry has entered the stage of industrialization construction and large-scale promotion and application. The key technology and product research of power lithium battery system integration is an important topic. The power lithium battery system integration features are as follows:
●Reliable mechanical connection
According to the vibration characteristics of the body, the installation and fixing structure of the lithium battery cell and module is designed to ensure the stability and reliability of the lithium battery pack.
●Up to IP67 full dustproof and waterproof protection
According to the application needs, the fully dustproof and waterproof lithium battery box is designed up to IP67, which can ensure the safety of the battery box when it is completely immersed in water.
●Up to 80% group efficiency
Provides up to 80% group efficiency through structural optimization and the use of lightweight materials
●A variety of thermal management methods such as air cooling, liquid cooling, and external heating
According to environmental requirements, various methods such as natural cooling, forced air cooling, forced liquid cooling and external heating can be used for thermal management to ensure the uniformity of the internal temperature field of the lithium battery pack
Summary: "Walking with lithium, lithium deserves you", under the responsibility of reducing energy consumption and carbon emissions, many well-known data centers are currently pursuing the goal of 100% renewable energy power supply, and lithium battery energy storage systems will enter the data center. become a big trend. The emerging lithium battery energy storage system can be combined with the UPS system, and the energy storage can also help the data center in energy-saving management, and the energy storage equipment can also interact with the power grid, and complete the peak load and valley load through power demand response. Manage and generate revenue for the data center.
