Flywheel energy storage technology for energy storage battery life

In recent years, China's energy storage industry has a good overall development trend, and the energy storage industry has basically been equipped with the conditions for commercialization. On the other hand, energy storage technology research and development as the core of the enterprise also began to figure out, and the number one is Beijing honghui international energy technology development co., LTD. (hereinafter referred to as honghui energy).

Wu hui energy was founded in 2015, on April 14, is a military and civilian integration, space technology transfer and civil high-tech enterprises, can provide advanced technology of flywheel energy storage and energy saving service, the technical team has won the national technology invention award, the company has won two national invention patents, has 10 national invention patents have been accepted, for 12 counts of software copyright, and at the end of 2016 was rated as "national high and new technology enterprise".

Honghui energy products are widely used in rail transit, power grid and factory emergency power protection system, UPS uninterruptible power supply, new energy, oil exploitation,special, and military industry and other fields. At present, it has gradually in part of the data center, subway lines, new energy storage, and other areas began to pilot. In the future, the energy storage industry will create great value for China's economic growth and green energy development.

Many a little makes a mickle

Hong hui energy is led by the first prize winner of national technology invention, gathering top experts and scholars in the fields ofspecial, power electronics, automatic control and energy from famous universities and research institutes of science and technology, and has developed internationally leading series flywheel energy storage technology and products with completely independent intellectual property rights.

"In response to general secretary xi's call for civil-military integration and conversion of space technology to civilian use, we set up honghui energy in 2015. In fact, Chinese scientists have been working on flywheel energy storage technology for more than 20 years. Wang jialiang of chairman of energy of hong hui energy expresses when accepting print reporter to interview.

Flywheel energy storage refers to the energy storage method that USES the motor to drive the flywheel to rotate at a high speed to convert the electric energy into kinetic energy and store it. When necessary, the flywheel drives the generator to generate electricity and convert the kinetic energy into electric energy. "Previously, this technology was first used onspecials, which can effectively improve the resolution ofspecials, and refine the accuracy ofspecials from hundreds of meters, tens of meters to a few meters or even a few centimeters. With the development and maturity of technology, it is also widely used in the civil field andspecial industry. "Wang jialiang said.

And foreign research and development and application of this technology is bound to be China's secret blockade. "Abroad, flywheel energy storage technology is the best done by Boeing, Raytheon, but the level of secrecy is also very high. Therefore, in the 1990s, our country assigned research and development tasks to the military, universities and other teams, and the university team is the best later - that is, the Beijing University of aeronautics and astronautics team. "The team started their research in the 1990s, and by 2007 they had successfully applied it tospecial applications," wang said. At the same time, the core technical personnel of the team also won the first prize of national technology invention award, which was a blank for many years before, and its gold content is very high. Thus, on a technical level, the team represented the highest level of flywheel energy storage technology at the time, including the technology that was later used by severalspecials on arrow 20.

"Around 2014, the country started advocating 'civil-military integration,' and we were actively looking for partners," wang recalls. After the introduction of relevant leaders, hong hui energy management team and technical team came together. "According to our understanding, flywheel energy storage technology in the future in civilian applications will also have a broad prospect. So after repeated communication and exchange, we set up hong hui energy in early 2015.

Is the so-called "gentleman to move, and the trend", the management team and the technical team "hit it off" also for hong hui energy laid the foundation for the development of the trend. On October 11, 2017, the national development and reform commission, the national energy administration and other five departments jointly issued the guidance on promoting energy storage technology and industrial development (hereinafter referred to as the opinions). The opinions point out that China's energy storage technology shows a good trend of diversified development -- pumped storage develops rapidly; Research and development and application of energy storage technologies such as compressed air energy storage, flywheel energy storage, superconducting energy storage and supercapacitor, lead battery, lithium ion battery, sodium sulfur battery and liquid-flow battery have been accelerated. The technology of heat storage, cold storage, and hydrogen storage has also made certain progress, which indicates that China's energy storage technology has entered a new period.

The opinions highly approve the past technological development route, and boldly predict that China's energy storage technology, on the whole, has preliminary industrialization basis. The release of opinions is a "set tone" for the development status of energy storage technology and equipment. It proves that China's energy storage technology is on the whole in an important stage of transition from demonstration application to early commercialization, which will surely lead to a new wave of energy industrialization and a number of innovative manufacturing enterprises. In this wave, honghui energy, with profound technical deposits and first-mover advantages, may become a "trendsetter" in the energy storage industry, leading the development and progress of flywheel energy storage technology.

"Flywheel energy storage is actually a physical battery technology." "Traditional chemical batteries, such as old lead-acid batteries, zinc-manganese batteries and the most popular lithium batteries, mostly convert chemical energy into electrical energy," wang said. The production process and the processing link need the huge environment cost and so on. The flywheel battery can withstand tens of millions of charges and discharges, and has a service life of up to 20 years. This can be said to be a true sense of energy-saving and environmentally friendly battery, "in addition, in the use of the process mainly rely on mechanical energy and electrical energy conversion. "Technically, it is also a high-power battery that can release huge amounts of power in an instant and can be used in many fields.

Technology starts at the right place

In the field of flywheel energy storage, honghuineng has fewer competitors in the domestic market and its technical strength is at the forefront. The research and development of flywheel energy storage field is a system engineering, which requires the cooperation of different research and development talents in different subdivision directions. Hong hui energy has gathered the talent team of flywheel energy storage technology research and development laboratory of Beijing university of aeronautics and astronautics, with more than 10 years of research and development experience and technical reserves, and has obvious competitive advantages.

Hong hui energy's main product is flywheel energy storage device, which belongs to the physical battery. Under the charging state, it can convert the electric energy into the kinetic energy of the flywheel that rotates at high speed under the vacuum environment of magnetic suspension. In the state of discharge, the kinetic energy of the flywheel can be converted into electrical energy. Compared with traditional chemical batteries, flywheel energy storage products have a wide range of working environment temperature, charging and discharging times (up to more than 20 million times), environmental protection and pollution free, small size, can withstand the impact of high power, long life (20 years), charging and discharging speed, and other advantages. It is reported that the company's products can now reach the maximum speed of more than 30,000 RPM.

At the end of 2016, honghui energy was awarded as "national high-tech enterprise". In the same year, hong hui energy flywheel energy storage products were successfully included in the "second military and civilian integration development high-tech achievements exhibition" product list. The company has good channel resources. At present, it mainly obtains orders in the data center uninterrupted power supply market, and is vigorously exploring the industrial uninterrupted power supply market, rail transit energy recovery field, wind power, and solar power grid integration field and other markets.

"Our current exploration in the civil sector has shown initial results, especially in the data center industry, which has been relatively successful." "We have reached a consensus with sunbeam, a listed company under the Chinese academy of sciences, on the application of data center industry," Wang said confidently. Recently, at the invitation of the ministry of industry and information technology, senior executives of the company attended the fourth world Internet conference in wuzhen and made a special report on "flywheel energy storage technology service" at the conference, which was well received by people from all walks of life around the world. "The traditional data center industry used to build a lot of battery rooms and air conditioners, which took up a lot of land," Wang said. "what we really need to change in the future is the model of the data center industry.

"On the other hand, the technology can also be used for environmental protection, energy saving and energy recovery, which is mainly manifested in the use of subway." "We all know that the subway is a big consumer of electricity," wang said. During the braking process, there will be varying amounts of heat and electrical energy conversion loss, and if we apply our flywheel energy storage technology on the platform, the subway will be able to collect all the energy when braking in the station, and then we will 'return' the energy to it when starting from the station. In this way, the subway can save 20% ~ 30% of energy consumption. "We have taken an important step and will soon begin to implement it. Flywheel energy storage technology can also be used in oil drilling. "The drilling depth is usually thousands of meters, traditional drilling to use a number of large diesel engines, but now drilling through flywheel energy storage technology can greatly save energy," wang jialiang said, while showing off, "in the oil drilling rig down, the flywheel system can absorb braking energy; The flywheel system releases stored energy as the oil rig is lifted.

"Recently, we won a bid in chengdu, the world's second largest wafer foundry chipmaker grofand will spend 10 billion dollars to build a 12-inch wafer plant in chengdu, with a project investment of nearly 10 billion dollars. "Chip plants have the highest power quality requirements of any industrial project -- no power cuts, and no fluctuations in the power supply," wang said. The project was originally monopolized by several foreign companies, and through our efforts, we won the order. According to the introduction, in the future, in the integrated circuit industry, in OLED (organic light-emitting diode), sapphire crystal, biological manufacturing and other high-end manufacturing industries need to be flywheel energy storage technology to provide security and save electricity.

After preliminary layout of data center industry, environmental protection and energy saving, honghui energy will start the journey of new energy reserve closely following the national pace. "Wind and solar power rely on natural wind and solar power to generate electricity, which is unstable, and the company's products can provide protection for wind power and solar power when they are connected to the grid. In the long run, we will strive to make flywheel batteries lighter and more efficient, which will be used in new energy vehicles,special magnetic resonance and other aspects in the future. 'new energy is an inevitable trend, and the state is supporting it, but we can't always rely on state subsidies,' Mr. Wang said. The key to the development of new energy is to see who can develop the technology to a higher level and at the same time bring down the price. Therefore, we are also stepping up research and development. We hope to reduce the cost and provide better services for users through technological transformation.

Pragmatic and ambitious achievements in the future

Hong hui energy office is a very chic siheyuan, "hong hui hall" in the three words between the brick and red walls is very clever. Dr. Meng tiezhu, chief financial officer of hong hui energy, told reporters that the company's headquarters and sales are in the courtyard, while the research and development center and production departments are in Beijing shunyi. Jia-liang wang said, "a few in our company, a professor at beihang are abandoned in buaa development opportunities and join us, and the people's liberation army equipment college professor directly to resign turned to our company", although the company is divided into two parts, but wu hui energy is all as one, strive for flywheel energy storage.

"In fact, the most important asset of an enterprise is its talent. In my opinion, in order to retain talent, an enterprise should not become a one-person enterprise, but develop into an enterprise for everyone. So, we decided from the very beginning in terms of equity design that the senior staff and technical core members should have shares in the policy. Wang jialiang said thoughtfully, "in addition, it is more important to let everyone have a sense of mission and fully realize that what we are doing is a great cause that can truly create green environment for the country and society, so that everyone can see that we are not only going to be a company in the future, but also to form an industry. At the same time, we are willing to accept more partners to join us in the form of capital, because the cause is to involve more people and make us bigger and stronger together.

Therefore, listing the new four board is only the first step of hong hui energy contact capital. Its long-term strategic goal in the future is to base itself on the flywheel UPS market, aim at the global technology frontier, continue research and development, vigorously expand the energy recovery and new energy storage market, in order to achieve technological breakthroughs and industrial upgrading in many fields.

"The new fourth board market has shaped our company into a normative enterprise from the very beginning, which is to get the 'way' right and make a good endorsement for landing on the main board. "All aspects of the enterprise, such as talent construction, financial system, sales management, internal control system and so on, have been very standardized, and the construction of intellectual property rights has been improved a lot.

"In fact, for us, listed on the new four panels and landing motherboard listed are just some forms such as in the future, these things are the external, it can make enterprise more specification, let more people know about wu hui energy is more and more confident," jia-liang wang said, "but companies won't put too much energy or focus on the above, for just 1 'gong', but there is still a long way for us to go, we want to technology development through the efforts of the team, our core technology, the enterprise values grind, and pass to continue passing down from generation to generation. That is to say, it is more important for us to do something that will outlast our lives. (article/print journalist li shanshan)
