High-power lithium-ion battery energy storage to solve the difficult problem of wind power

When the domestic industry, academia still lively discussion of wind power Acer Aspire 2200 battery into high voltage power system solutions, countries have begun the first construction of infrastructure. Reporter yesterday learned that the current China Southern Power Grid has begun to use high-power lithium-ion storage battery construction in Shenzhen, wind power facilities, "after the first store delivery" to solve the wind power problem.

 

It is understood that the current hybrid cars use nickel-metal hydride battery technology, Normal 0 7.8 磅 0 2 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:普通表格; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} ACER Laptop Battery  HP Laptop Battery, nickel-metal hydride batteries, but some of the technical properties such as energy density, charge and discharge speed is close to theoretical limits. The lithium battery has energy density, high-capacity, no memory, etc., by various car manufacturers and battery manufacturers unanimously approved, is currently the focus of national research and development of lithium-ion batteries.

According to the different cathode materials, lithium batteries are lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate ternary materials, and four. Lithium iron phosphate which is the best vehicle to use lithium cathode material. At present, China's car prices electric car models introduced, the power batteries are lithium batteries, Chery, BYD are using lithium iron phosphate.

Although China ranks third in the world production of lithium batteries, but in products, technology level with Japan, the United States there is a certain gap between the vehicle's lithium battery industry has not really started. Xinhua said the letter, and other related research institutions, China's relatively backward power battery production equipment, many companies will focus on the material, ignoring the improvement of manufacturing equipment. At present, China mainly depend on production of batteries and equipment imports expensive, which our car is very unfavorable development of battery, battery in mass production, it should be advanced automation equipment research first. In addition, most of the enterprises of independent power battery research and development, its limited funds, can only solve the basic problem of battery technology is difficult to further advance. Lack of adequate communication between enterprises, want to know the circumstances of other people do not want to talk about their own experiences, there is widespread duplication of low-level phenomena.

In an interview yesterday, New Energy Co., Ltd. Zhuhai JETCO said Zhang Bing, deputy general manager of the above information. According to him, the current project countries are on the storage battery tender. The company is building security with 50 million when the battery energy storage capacity of large-scale production base, the product will be large-scale use.

-2,009 In 2006, China's wind power installed capacity of 4 consecutive years, to double-type growth. According to the China Electricity Council statistics,Laptop Battery in 2009 the national wind power installed capacity reached 16.13 million kilowatts. But the State Electricity Regulatory Commission, "The Survey of China Wind Power Report" shows as "sent hard" issues such as wind farms across the country in general and even loss of operational difficulties, there are nearly 1 / 3 of the wind turbine is idle.

Experts, such as wind power vulnerable to weather factors, and the network will affect the system's voltage fluctuations and power quality. Therefore, many experts say, "After the first storage carrier" is wind power the best way into the high-voltage power grid. However,Dell Inspiron e1705 AC Adapter   Dell Latitude E5500 AC Adapter due to the high cost of energy storage batteries, short life, the best way to previously difficult to achieve.

Well-known motor, electric drive and electric car experts, the Chinese Academy of Engineering CC Chan introduced the initial resolution of this problem has been. Taiwan and other new types of lithium iron phosphate lithium ion storage battery live longer, be able to power the battery energy storage batteries and extensive application of this technology has been developed by the Mainland and put into practical application.
