The increasing opportunity of Capacitor enterprise in the

rapid development of new energy industry

Recently, the state council meeting held by the standing to review "the state council about to speed up cultivating and developing strategic decision of emerging industry, the energy conservation, environmental protection, a new generation of information technology, biotechnology, high-end equipment manufacturing, new energy and new materials, new energy vehicles seven industry will be cultivate, speeding up.
　The meeting will determine to seven industry tax increase financial policies support and the establishment of strategic emerging industry development special fund. Compared with the traditional industry, seven big industry start later, at present, in the hot market is unsustainable background, seven big industry will undoubtedly become the new "high", the subdivision of the field in hundreds of listed companies are expected to benefit from new energy vehicles, and the national various support policy also are being made in, present known "energy conservation and new energy vehicle development planning (2010 2020)," in the show in the draft, and the central government will put more than 100 billion yuan to the development of new energy vehicles industry. All walks of life, all eyes will be to new energy will give their respective industry brought about by the new opportunities.
　In the new energy and new energy vehicles in the field, for capacitors for industry, not only as a new energy for control system, power management system, power inverter and dc exchange switched system and related upstream enterprise is a rare historical opportunity, at the same time, no doubt, to the indispensable capacitor industry also brought a rare opportunity of development.
　A, new energy fields
　The new energy and energy, it is to point to unconventional says traditional energy outside of the form of energy. Refers to the development and utilization of beginning or are actively research and promotion of energy, such as to solar, geothermal, wind energy, oes, biomass energy and fusion can wait.
　Now countries are in strongly advocated the use of wind power, solar power, this is clean energy. So now, more and more companies in the design of solar power, wind power generation power management system, in the model selection of the main is high voltage, large let value of capacitors have great products demand. Such as wind power products system, in three places to use this product, capacitor first film capacitor can choose to do the application of high voltage absorb; Another is a DC-LINK, DC-DC conversion process, the role of the filter energy storage; And when the grid and anti-jamming capacitance. See chart one shows.
　Need to explain, general this three paragraphs, everybody's most attention in capacitance is DC-LINK capacitance, general users have two kinds of capacitor can choose, the first is the electrolytic capacitors, especially in DC-DC conversion unit, it's the job of　the voltage is 690 v, capacity is 3300 to 4700 uF, these are only small power wind power system in the application. High power unit situations capacitors will double the number.
　Aluminum electrolytic capacitor voltage is generally highest in 450 V (but now it has developed the highest voltage up to 600 V), so how in 690 V the voltage value used under? Needs at least two aluminum electrolytic capacitor series about 900 v voltage satisfy the requirements of more than 690 volts, general like the voltage stabilizer and filter capacitor, if use electrolytic capacitors words, all need a lot of aluminum electrolytic capacitors series and parallel, to reach a lot of capacity and high voltage resistance　value the use requirement. Dc application occasion can also choose to use film capacitor, film capacitors applications capacity value and electrolytic capacitors is same, but its value can withstand voltage directly do 690 v, don't need through the series and parallel to meet the requirements of the pressure.
　How to choose the aluminum electrolysis capacitor and film capacitor? In exactly the same applications, it is the electrolytic capacitors film capacitor still USES? The trend of the future is to use certain film capacitor is given priority to, the benefits of using film capacitors have the following four aspects:
　1. Aluminum electrolytic capacitor is liquid capacitor, first have a service life of limit, now a lot of solar energy, wind energy products final used users to have a life of the product demand, must be more than 15 years, the products in fifteen years must be reliable, because the wind energy products of the cost of maintenance is very expensive and difficult. Film capacitor is solid capacitor, it can just meet this requirement, use electrolytic capacitors have electrolyte materials, generally volatile't approach it 15 years of service life period, if want to reach the 15 years of life, means test during to replace two to three times.
　2. The second advantage is, because the film capacitor dielectric material characteristics, and determines its ESR value, and thus it low calorific value is very low, in addition, it can be very resistant to ripple voltage.
　3. The third characteristics, which have more wide use of the environment temperature range, this also is the characteristics of liquid capacitor and solid, the difference between the capacitor, film capacitors in the low temperature of the work state of stability is very good.
　4. Film capacitor filtering ability stronger than aluminum capacitors capacitor many times. Filter can be used if better film capacitor, conversion efficiency is higher. This is now in the wind, solar energy application development trend.
　So, the future for nantong jianghai capacitor Co., LTD in the film capacitor investment decision is very necessary, also is in the near future will brings profit increase.
　In addition, in the solar energy application, because the super capacitor cycle count can be up to hundreds of thousands of times, life characteristics is far superior to the other battery products, such, can solve especially in high altitude and airtight state concerns, and maintenance free, so often will use a super capacitor as the energy storage device to replace the traditional lead acid battery, traditional lead-acid battery life is in commonly 500 times or so. For example, solar lights, traffic light have application example.
　Of course, new energy industry in addition to bear high pressure, high electric capacity electrolytic capacitor, film capacitors and super capacitor industry has brought to the market demand, other conventional capacitor demand will also bring new growth. In the　application of the new energy, in addition to the outside, for example on other occasions specific application case also is endless.
　Second, new energy vehicle field
　Latest news, October 4, in tianjin opened the fourth time this year the United Nations conference on climate negotiations, issued by the Chinese ministry of science and technology in the development of the 2010 clean energy "report, our country will end in public transportation field application 20000 a new energy vehicles.
　The report points out, the government has put a new energy vehicles as a strategic new industry to develop one of. In 2009, the first 13 "ten city 10 vehicles" demonstration projects, public transport, and rent in city, business, environmental sanitation and postal public services such as the field to promote the use of new energy cars. By the end of 2009, the national demonstrated and all kinds of new energy vehicles nearly 5000 cars, have 70 new products to the market.
　Demonstration project effectively drive the folk capital on power battery, motor drive, to the investment of 2011 years, can form 150000 cars and key parts production ability.
　The report also explicitly pointed out that, by the end of 2010, China's "ten city 10 vehicles" demonstration project will be in public transportation field application out over 20000 domestic car, drive new energy application of the market more than 150000 units. In 2015, China's new energy auto possession to 1 million or more cars will, in 2020, new energy vehicle market scale will reach 10 million a level of China's automobile industry, realize technology strategy transformation.
　The electric car integration system is involved with the power DuoGe technology field, in the field of high technology intensive industry products, the core technology of the electric car is also the focus of competition and industry. Through the country more than 10 years of key support, although China in the electric car with motor and its drive system, storage battery charging system, technical equipment related key technology and product research has made a great progress, but with the foreign system integration of the function of the product still has a large gap.
　As the industry, capacitor in the following aspects: the use of
　1. The charger (pile) and charging station system
　Because cnac, the national power grid, southern power grid, the oil, cnooc and other industry giants' involvement, China energy-saving and of new energy industry to an unprecedented heat expedites the height of will no doubt to our country, the development of new energy vehicles plays an important significance. At the same time and the original petrochemical supply system to build battery charging station system not only convenient, and cost more to save for the popularization and charging station, electric car has also play the more active role.
　Currently charging scheme has the following four plan:
　1) change the battery solution: support the scheme of nissan, echoo buses, south car era
　2) charging scheme: support plug of the scheme have saic, byd
　3) hybrid plan: support the scheme of general motors, Toyota, ford, mass
　4) process scheme: the support it with several well-known brands of abroad is given priority to
　No matter what, there is always more than scheme based on AC-AC, DC to AC, DC-DC-and DC-AC conversion technology platform, the filtering process, the capacitor is indispensable components. Particularly want to put it, the low voltage DC-in DC converter system, solid electrolytic capacitor is first selection and optimization of the device, because solid capacitor have low to the ESR, the long life, wide temperature characteristics and is especially suitable for outdoor low temperature condition in the north the characteristics of the work. Some charging system will still use to the secondary unit system, such as: EPS/UPS, high-voltage inverter, high voltage switch power supply system, these are the traditional market industry capacitor.
　2. Electric power management system
　As a power battery management system, in addition to various battery power management, but also for the power supply output management, including the control unit of power auxiliary management, some systems need to consider the design on the compensation and　absorb energy downhill, and so on, as a car with electronic components has many use environmental uncertainty characteristics of, so the more stringent requirements will have.
　In the hybrid system, as the compensation of the energy and absorption of scheme by super capacitor set some energy storage, so, for the way super capacity super capacitors will has a large demand, the Shanghai world expo electric car is very good examples. At the same time, as a large capability super capacitor growth and industrialization, electric cars will play a important role.
　epilogue
　New energy and new energy to the development of the auto industry is undoubtedly a new energy revolution, marked the new industry and the industrial revolution is coming, the climax of the association industry brought the opportunity and the challenge, as kit with the basic electronic components of the capacitor industry also brings many development opportunities, especially high voltage, large capacity aluminum electrolytic capacitor, solid aluminum electrolytic capacitor, film capacitor, super capacitors will bring considerable development opportunities。
