In which fields does rack UPS power supply apply to the industry? The following Li-Ion Battery Energy Storage System Supplier will tell you.

1. Data center

Rack UPS power supply system plays an important role in power supply protection in data centers in various industries. To provide uninterrupted power supply to the load, it must have the function of energy storage. For data centers, the most important thing in the entire operation process is energy efficiency. The level of energy efficiency directly reflects people's attitudes towards sustainable development and climate change. Data center operators are considering how to better apply the foundation UPS power system in the facility to maximize efficiency while providing consistency and flexibility with minimal capital expenditure.

2.Integrated cabinet

The integrated cabinet deeply integrates data center infrastructure products, including multiple subsystems such as UPS, power distribution, refrigeration, cabinets, and fire protection. It implements overall management of all systems through the monitoring system, simplifying the design and construction process. Reliable UPS power distribution system constantly escorts IT equipment, while equipped with a precision refrigeration system to ensure the operating environment of IT equipment, and with a dynamic ring monitoring system to monitor the working status of the equipment in real time. The integrated cabinet adopts a fully sealed design, which can be used in a variety of harsh indoor environments without the need to set up a separate machine room.

Rack UPS adopts Rack Mount Li-Ion Battery System. It is designed for racks in computer rooms. It can be placed in standard cabinets like other storage devices, hard disk recorders and the like. The shape design adopts the most widely used 19-inch standard rack cabinet at present. The rack-mounting method makes the machine in size (small footprint), layout (link wiring in the cabinet), visual (unity and simplicity), and reliability ( Preventing mishandling and contact) is superior to traditional tower UPS power supplies.

In terms of availability, management, adaptability, system protection, the rack-mounted UPS power supply is more intelligent and efficient, and has protection functions such as battery over-voltage protection, output over-voltage protection, output under-voltage alarm, output short-circuit, and over-temperature. Therefore, in the computer room integrated power distribution cabinet where high-precision uninterruptible power supply is required, selecting a rack UPS is a very good choice.

3. Power industry

The working principle and output characteristics of electric UPS are exactly the same as traditional UPS. However, since it is connected to a DC operating power system, its DC input characteristics must meet the special requirements of the power system. Power UPS is designed for power plants such as power plants and substations. In power systems such as power plants and electric power, DCS (distributed control system), monitoring systems, automation instruments, dispatching communication systems, microcomputer systems and other core equipment affect the quality of power supply and Reliability requirements are very high, and a dedicated UPS is required to supply power. Most of these loads are single-phase loads.

4. Rack UPS power supply, as the most commonly used power supply guarantee facility in data centers, and the largest loss in the power supply and distribution system, plays an important role in the financial industry. Banks and financial companies must maintain many small systems that require individual power protection. Automatic teller machines (ATMs) require online rack-mounted UPS protection to avoid possible power supply anomalies.

The above are a few areas in which rack UPS power supplies are widely used introduced by ESS All-In-One supplier. I hope to help you.

What Is A Rack UPS?

The current computer room, system integration, and integrated cabinets are ubiquitous. The existence of rack UPS power supplies has solved many problems. It has provided great help to many computer rooms, data centers, workshops, and units. Existence is inevitable. Rack-mounted UPS rack-type design, the appearance design adopts the most widely used 19-inch standard rack-type chassis, the appearance is simple, and the installation is convenient.

It is widely used in communication, electric power, public security, fire protection, radio and television, finance, military, Internet and other industries. The matched and integrated equipment includes: communication base stations, integrated power distribution cabinets, data centers, and modular integrated products. The UPS Lithium-ion Battery System Supplier introduces the rack UPS in detail.

Rack UPS power system consists of five parts: mains, bypass, battery and other power input circuits, AC / DC converter rectifier (REC), DC / AC converter inverter (INV), inverter and Bypass output switching circuit and energy storage battery.

UPS Lithium-ion Battery System

Normally, the mains power is converted to direct current to charge the battery by a rectifier, and at the same time, the inverter outputs high-quality AC purified power for important loads, so that it is not affected by the mains voltage, frequency and harmonics. When the mains power fails for some reason, the system automatically switches to the battery pack, the battery discharges, and the inverter supplies power to the important load.

UPS Lithium-ion Battery System works:

The rack UPS power supply rectifies the mains AC power when the machine is working and stores it in its own power supply. Once the power supply is stopped, it can provide power and use electrical equipment to maintain a working time. The holding time may be 10 Minutes, half an hour, etc. The delay time is generally determined by the capacity of the battery.

When the utility power is supplied, it is the role of the voltage regulator and filter to eliminate or weaken the interference of the utility power and ensure the normal operation of the equipment; when the utility power is interrupted, it can provide the The DC power is converted into perfect AC power for the load. Among them, the mains power supply to the battery power is usually switched in 0 hours. This allows the load equipment to keep running without feeling any changes, which truly guarantees uninterrupted operation of the equipment.

The above is the information about the rack UPS introduced by the ESS All-In-One supplier. Hope to help everyone.

Life Of Rack UPS Lithium Battery

Rack UPS is a type of lithium battery UPS. What is the service life of the internally equipped lithium battery? Since it is a lithium battery product, its life is generally "2000 times".

How long does a rack UPS lithium battery last? In fact, the service life of Rack Mount Li-Ion Battery System is generally not calculated by year and month, but by the number of cycles. Of course, the number of cycles is not just the number of charge and discharge but a cycle of charge and discharge.

Rack Mount Li-Ion Battery System

This life of 2,000 times also means that the rack UPS lithium battery has 2000 charge and discharge cycles. However, a charging cycle does not mean that the full charge of the lithium battery must be used before the next charging. Instead, when the lithium battery is used for a period of time, the battery is charged when it is less than half of its charge, and it is fully charged until the next day when the remaining power is used and then fully charged, it can be counted as a charging cycle.

However, the life of the 2000 charging cycles is not absolute, because if you spend more money, you can customize a rack UPS power supply with a longer cycle life.

After talking about this service life, Li-Ion Battery Energy Storage System Supplier also wants to tell you some ways to extend the service life of rack UPS lithium batteries. After all, after the lithium battery is manufactured, its capacity is limited, but during use, the correct use method and daily maintenance will help extend the life of the lithium battery of the rack UPS.

So how to extend the life of the rack UPS lithium battery? The following ESS All-In-One suppliers will come to tell you.

1. Use environment

The environment in which a rack UPS is used is also very important. It requires less dust, no corrosive air, and should not be exposed to direct sunlight. It must also have a good lightning protection effect. The temperature in the equipment room should also be controlled within a certain range, and the floor should be installed with an antistatic floor.

2. Access load

The most reasonable load range is 30% -60%. Full and overload use will affect the life of the UPS. Maintenance should be performed at least once a year.

3. Charge and discharge

Regular charging and discharging of a lithium battery can better extend its service life. Generally, it is completely discharged every 2-3 months. The specific time for discharging needs to be determined according to the capacity and load of the lithium battery. After a full load discharge is completed, recharge according to the instructions.

4. Correct power on / off sequence

The correct start-up and shutdown sequence should be to first turn on the UPS to supply power to it, and then turn on the various loads. This can avoid the damage caused by the instantaneous current impact on the UPS during the startup. The sequence is exactly the opposite during shutdown.

When using the rack UPS lithium battery, there are still many places that need attention. The correct method of use and daily maintenance can effectively extend the life of the lithium battery.

Status And Prospect Analysis Of Lithium Battery Industry

With the continuous development of 21st century microelectronic technology, the increasing number of miniaturized electronic devices, consumers have higher requirements for power sources, traditional batteries such as lead-acid batteries are increasingly difficult to meet market demand, and Lithium-Ion Battery Energy Storage System begins to reach the public.

Compared with traditional batteries, lithium batteries have the advantages of high energy density, high operating voltage, light weight, small size, small self-discharge, no memory effect, long cycle life, and fast charging. At the same time, because they do not contain heavy metals such as lead and cadmium, no pollution and non-toxic materials, so it is widely used in consumer electronics such as smart phones, notebooks, and tablet computers, as well as in new energy vehicles and energy storage.

With the large-scale application of lithium-ion batteries, the development of the lithium-ion battery industry is also strongly supported by governments of various countries. China has also issued a series of relevant policy documents to strongly support the healthy and rapid development of China's lithium battery industry. For example, in March 2017, the four ministries and commissions of the Ministry of Industry and Information Technology, the Development and Reform Commission, the Ministry of Science and Technology and the Ministry of Finance jointly issued the "Action Plan to Promote the Development of the Automotive Power Battery Industry", and proposed that the development and industrialization of new lithium-ion power batteries will be vigorously promoted in the next 5-10 years. To achieve large-scale applications by 2020. Under the guidance of policies, China's domestic lithium battery market has been expanding.

Rack Mount Li-Ion Battery System

Compared with power lithium batteries, energy storage lithium batteries are still in the market introduction stage, mainly due to cost, technical policies and other factors. Data show that in 2017, China's energy storage lithium battery output was 3.48GWh, an increase of 11.5% year-on-year; the same period, lithium-ion energy storage output value reached 5.5 billion yuan, an increase of 5.77% year-on-year, and is expected to be around 6.5 billion yuan in 2018.

As for consumer lithium batteries, due to the saturation of the consumer electronics market in recent years, the development of the consumer lithium battery market has slowed.

As one of the national development strategies, new energy vehicles have huge development potential. With the increase in the popularity of new energy vehicles and supporting facilities, and the gradual implementation of national policies, superimposed factors such as improved lithium battery production technology and lower costs, the demand for power batteries for new energy vehicles will continue to grow in the future. It is expected that Chinese cars will be in 2022 Power lithium battery output will reach 215GWh.

In terms of energy storage lithium batteries, China's energy storage lithium battery industry will enter the growth phase in the next 5 years, and the market has great potential. In the rising energy Internet, due to the large number of renewable energy and distributed energy access in large power grids, combined with the popular application of microgrids and electric vehicles, energy storage technology will be a vital part of coordinating these applications. The energy storage link will become a key node of the entire energy Internet; the rise of the energy Internet will significantly drive the demand for energy storage.

The rapid progress of lithium battery production technology has reduced the cost of lithium battery products, which will increase the competitiveness of energy storage lithium battery products compared to other energy storage technologies. The market penetration of lithium batteries in the energy storage field has gradually increased, such as Rack Mount Li-Ion Battery System will also further promote the corresponding growth of the application market size. It is estimated that by 2022, China’s lithium-ion energy storage output value will increase to 13.7 billion yuan.

In contrast, the future growth of consumer lithium batteries is relatively small. However, due to the rapid upgrading of consumer electronics products, and the development of light, thin, short, and miniaturized, the demand for lithium batteries with small size, large capacity, light weight, and high energy density is showing a rapid growth trend. Therefore, with the further improvement of people's quality of life and per capita income, the demand for consumer lithium batteries is expected to maintain a certain growth.

The above is the current situation and prospect analysis of the lithium battery industry introduced by Li-Ion Battery Energy Storage System Supplier.

What Are The Advantages Of Lithium Iron Phosphate Batteries?

Lithium Iron Phosphate Battery is the branch of lithium ion battery with lithium manganate, lithium cobaltate and ternary lithium battery. Its performance is mainly suitable for power applications. At this time, it is called lithium iron phosphate power battery, also known as lithium iron. battery. Therefore, the advantage of lithium iron phosphate battery mainly refers to its comparison with other batteries in power applications. In this sense, it will mainly compare its comparative advantages with ternary lithium batteries and lead-acid batteries.

First, the high temperature advantage compared with the ternary lithium battery. Lithium iron phosphate battery has better high temperature performance and can withstand high temperatures of 350°C ~ 500°C, while lithium manganate / lithium cobalt oxide is usually only about 200°C, the material of the modified ternary lithium battery will also be Decomposition occurs at 200 °C.

The "elderly" among the two and three - absolute longevity advantage. Lithium iron phosphate batteries have longer cycle life than lead-acid batteries and ternary lithium batteries. The "long life" of lead-acid batteries is only about 300 times, up to 500 times; the ternary lithium battery can theoretically reach 2000 times, and the actual application to 1000 times will be attenuated to 60%; and the real life of lithium iron phosphate battery That is to reach 2000 times, at this time there is still 95% of the capacity, and its concept cycle life is more than 3,000 times.

Third, compared with lead-acid batteries, the advantages are many:

1. Large capacity. The monomer can be made 5Ah~1000Ah (1Ah=1000mAh), while the 2V monomer of lead-acid battery is usually 100Ah~150Ah, and the variation interval is small.

2. Light weight. The lithium iron phosphate battery of the same capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the latter.

3. Fast charging ability. The starting current of lithium iron phosphate battery can reach 2C, achieving large rate charging; the current requirement of lead acid battery is generally between 0.1C~0.2C, and fast charging performance cannot be achieved. In addition, the Rack Mount Li-Ion Battery System can also store a greater degree of energy.

4. Environmental protection. Lead-acid batteries have a large amount of heavy metals - lead, which produces waste liquid, while lithium iron phosphate batteries do not contain any heavy metals and are free from pollution during production and use.

5. Cost-effective. Although lead-acid batteries are cheaper to purchase than lithium iron phosphate batteries because of their cheaper materials, they are less economical than lithium iron phosphate batteries in terms of service life and daily maintenance. The actual application results show that the cost performance of lithium iron phosphate battery is more than 4 times that of lead-acid batteries.

High Energy Lithium-ion Battery System-EFPE Series

Although the application range of lithium iron phosphate battery is mainly in the power direction, it can theoretically extend to more fields, which is determined by the various advantages shown in the above comparison, if in terms of energy density and discharge rate, etc. It is also possible to make some improvements and enter the traditional application fields of other types of lithium-ion batteries. The above is the advantage of the lithium iron phosphate battery introduced by the Lithium Iron Phosphate Battery Manufacturer. I hope to help everyone.
