Flywheel UPS "call board" battery UPS

In recent years, incidents of lead-acid batteries polluting the environment have frequently come into public sight. More advanced products that can replace lead-acid batteries have become the focus of attention.

Active Power, a company from Austin, United States, used a flywheel to store energy in a completely abandoned lead-acid battery, challenging the traditional lead-acid battery UPS.

Although only three years have passed since China entered China, FFS UPS has fully entered China's emergency power supply system. In 2009, the 60th anniversary of the National Day Power Guarantee, the 2010 Shanghai World Expo Power Guarantee, and the 2010 Guangzhou Asian Games power guarantee, the Flywheel UPS has played a significant role. . At present, in the most widely used and most rapidly developing data center of UPS, flywheel UPS is quietly changing the industrial structure of UPS.

“On the one hand, the increasing electricity cost of data centers, on the one hand, is startling lead-acid pollution, flywheel UPS can effectively solve these two problems.” Active Power's general agent in China General Manager of Beijing Grypian company Wu Bin Say.

The advantages of flywheel UPS are obvious. The first is energy saving. The first is that the energy efficiency of the flywheel itself can save energy. Active Power's products increase the UPS efficiency to 98%, while the traditional UPS power supply is 92%-93%. Do not underestimate this 6% energy saving. For tens of thousands For a square meter data center, the electricity cost saved in a year is amazing; secondly, the savings in air-conditioning and cooling costs. The battery is greatly affected by the environment. The operating temperature of the battery must be controlled at about 25°C. The flywheel UPS can operate normally at 40°C, which will significantly reduce air conditioning costs. Because of its low energy consumption, no need to replace batteries and air conditioning, the total cost of ownership of the power system TCO is reduced by 60%. The power saved by a power supply system using Active Power is enough for 101 homes for one year; second, provincial land, and the footprint of the flywheel UPS is only 1/4 of that of traditional lead batteries, which makes sense for many data centers. Yu. The third is time saving. With Active Power's modular power system, the deployment time will be reduced by 2/3, and the time savings will mean lower costs.

The economic benefits are good and the environmental benefits are considerable. Flywheel UPS uses mechanical energy storage to completely replace chemical energy storage. The data shows that lead-acid batteries inevitably produce a variety of lead-containing and lead dust during the production of lead-acid batteries. Generally, 63.2 kg of lead dust will be produced for every 1,000 batteries produced. These fumes can affect the surrounding air, soil and rivers. The direct consequence is that lead poisoning occurs when the content of lead in the blood is too high. It can cause a series of abnormal manifestations of the nervous system, blood system, and digestive system of the body. It can even seriously endanger life. The impact is particularly serious. Reducing the use of lead-acid batteries will undoubtedly reduce the risk of lead. In addition, from the standpoint of CO2 emissions, the use of Active Power's power supply system can reduce CO2 emissions by 818 tons per year, which is equivalent to 125 vehicles a year. Not to mention, that is, the energy storage method of lead-acid batteries.

It can be seen that adopting green and new energy sources as much as possible and reducing the use of lead-acid batteries is an irreversible trend of the times. Zhang Naiguo, an associate professor of the School of Information Science and Technology at Tsinghua University, emphasized that “heavy lead and sulfuric acid are the raw materials that pollute the environment. Flywheel UPS saves a lot of operating costs and CO2 emissions without batteries and large savings in air-conditioning equipment. It is a good green product. Should be vigorously promoted."

It is reported that Active Power products have been sold on six continents and are sold in more than 50 countries around the world, providing power protection for more than 750 megawatts of critical loads, with an accumulated uninterrupted operating time of more than 77 million hours. The cloud computing center of the world's largest search engine and the largest software company as well as internationally renowned companies such as VISA and 3M have adopted the Active Power power protection system.
