Planning the development of new energy vehicles

 

According to media development and reform of the Commission motor team leader Wang Shulin, has revealed “new energy program for vehicle development was presented to the Council of State should officially promulgated in March 2010. In addition, State agencies will also be launched next year, development of new energy vehicles for the five accompanying measures. Analysts estimate that the new energy industry of the Laptop battery will most benefit from the concept of new energy vehicles.

 

The new energy vehicles in March next year, introduced the planning or

 

If the concept of energy market news, sauteed, in policy came good constantly. Held recently in Nanchang, the new energy vehicles and lithium-ion batteries feature forums, the National Development and Reform Commission automobile team leader Wang Shu-lin said that China will soon release of new energy vehicles, specifications techniques, and new energy vehicle development presented by Development and Reform Commission of the State Council, was officially promulgated in March next year.

 

CITIC Securities (600.03 miles, Bar Stock) Auto Industry Analyst Cheng believes that this concept of some new businesses IBM ThinkPad X60 battery power, as Shanshangufen (600884, bar stock), Jiangsu Guotai (002091, bar stock), companies production of batteries, etc. to receive more, but for the entire automotive sector in particular, SAIC, FAW and other major car companies have little effect. Energy vehicles would be the automotive industry and its upstream segment of the cell concept of society have an impact. March release, “the restructuring of the auto industry and the revitalization plan” submitted in 2011 to form a production capacity of 500,000 short-term goal, which is currently more than 1300 million units for the production of the automotive industry is concerned, a very small proportion of new energy vehicles. For their own societies smallest battery to the past, mainly the provision of mobile phones, computers and other battery-quarter production traction batteries, 500,000 will be a huge volume of activity, hence the emergence of new energy concepts will greatly enhance the performance of these companies.

 

From March 2009 “published by the restructuring of the automotive industry and the revitalization of planning” in response to vehicles with new energy into the electric car, Development and Reform Commission has been clearly put forward in 2011 to form a production capacity of 500,000 short-term goal. It is understood that electric vehicles, power VGP-BPS10A batteries, electric motors, power electronics, the cost of key components, which represents the cost of electric vehicles by 30% -50%. Based on the calculation of 500,000 electric vehicles with a value of annual production expected to reach 1,000 billion yuan.

 

Previously, the two countries issued a joint statement in Beijing, the two sides agreed during the next five years, Sino-US Joint Research Center of the investment for clean energy at least 150 million U.S. dollars the priority research topics will own cars. The market believes that Sino-US Joint Declaration on cooperation in energy sources such as news, digital, relatively rare in history, new energy vehicles are expected to form a positive plate material.

 

The State Council Development Research Center of Industrial Economics Research Department, Feng Fei energy experts believe that both parties should take the initiative in the field of electric vehicles for cooperation, Xinhua China (600,795, bar stock) in a car walk has a large market and low manufacturing benefit costs, however, the overall level of automotive, industrial technology, the infrastructure was not enough, the United States, it is precisely in this area has a great advantage if both parties take the initiative in the field of electric vehicles to launch a new type of automotive products, will become a reality.

 

Automotive Li-ion batteries to double next year transfers

 

As environment-friendly vehicles worldwide are sought, the hybrid electric cars and sells the coming years, the automotive market lithium will develop rapidly. Fuji Institute of Economic Research said that from the 2010 car market lithium batteries will quickly recover and continue to grow. The report predicts that by 2014, manufacturers of batteries that the overall amount of total shipments in 2008 increased by 45.2% to 6.2392 billion yen. Among them, rechargeable hp Pavilion dv4 battery market will be extended to 4.9983 billion yen, an increase of 66.8%. It should be noted that the needs of the automotive industry will become the main engine of expansion of the battery market is expected in 2009 shipments of lithium batteries automotive sector will amount to ¥ 10,400,000,000 in 2008, based on double ¥ 25000000000; In 2014, the market size will expand rapidly to 2.25 billion yen, or about 215 times in 2008.

 

Management Consulting International firm Roland Berger Strategy on the global outlook for new energy vehicles in the last research report predicts that by parts of the electric power in 2020, China is the drive assembly and components market worth 10 billion euros Chao, whose 2011, 2014 and 2017 the market value of 600 million euros, respectively, 2.4 billion and 56 billion euros, the estimated market value of the environment in 2020 will reach 6.5 billion euros, even a conservative estimate will reach 2.4 billion euros. According to forecasts the next 10 years, Chinese enterprises in the hybrid and electric vehicles future developments in the field have an advantage, in particular, the basic components, including developments in the field of toshiba PA3191U-3BRS battery has a great potential because Chinese companies have the advantage of cost of raw materials, manufacturing equipment and labor cost advantage.

 

According to Roland Berger predicts that 2020 will be the main markets in Western Europe, electric vehicles and plug-in hybrids will be more than 3 million in annual sales, China ranked second to reach 1.58 million of units.

 

With the plug-in hybrid electric vehicles of all relevant factors, the Roland Berger predicts that by 2020, elements of the battery of the global market share in the largest share of the market size of EUR 9,600,000,000 — 297 between. Now that the Chinese suppliers and Japan, South Korea, North America, Europe, the supplier has a significant cost advantage compared to, the future of the standard battery of quality, durability and differences prices will become increasingly small.

 

Roland Berger estimates that the demand for battery electric vehicles will be the future of lithium the main source of output growth is expected for 2020, there will be eye-catching 70% of average annual compound rate of growth. Despite the significant growth in demand, but because of higher reserves, experts do not believe that the production of lithium will be a shortage, but there may be a price increase in the risk of a temporary existence.

 

Promising varieties of independent innovation of automotive batteries

 

Shenyin analyst Wang said that under optimistic about new energy policies to promote investment opportunities in the automotive battery industry, promising varieties of independent innovation of automotive batteries. Shenyin the next 3-5 years, Ni-MH batteries, HEVs will remain the mainstream of new energy vehicles, HEVs will PH EV, EV co-existence about 10 years. In 3-5 years later, with iron to increase the performance of lithium phosphate to lower costs, and the national network of charging stations in place progressive lithium iron phosphate as the main engine PH of the EV, EV mark the beginning of a broad development prospects. Recommended Section Li Yuan (600,478, bar stock), Shanshangufen, Jiangsu Guotai, Tibet Mining (000762, shares bar).

 

Shenyin should grant political future, and the rate of localization is likely to hook. In the development strategy, pending the countries new energy vehicles as an opportunity to catch up from behind their own technology. I believe Sino-US cooperation, China will continue to insist on independent R & D path. Possible future introduction of new energy standards car allowance, spare parts and the main rate of localization will be linked to, and encourage the autonomy of key parts as soon as possible and depending on the location of raw materials. At the same time the state will improve the access threshold, and rigorous review system products.

 

Shenyin should follow the state ministries and commissions, will be introduced to encourage large-scale electrical vehicles and the development of specific incentive policies. The industrialization of new energy vehicles, including the most important policy for consumers to buy new energy vehicles are subsidized, and the development of new VGP-BPS10A/B energy vehicles and infrastructure planning. The introduction of these two policies that will address bottlenecks in the consumption and use of the bottleneck.

Battery power supply design is the development of chemicals and the workers of scientific research, technical staff, knowledge and skills.

 

1. Battery Design Basis

 

• The design goals of battery and the basic principles of

 

Cell is the design of instruments and equipment to provide the best use of the performance of work or power outlet. Therefore, the design of the Laptop battery must first be used to meet the electrical requirements and optimize it with the best overall performance, to determine the battery electrode, electrolyte membrane, Shell and other parties parameters, and they are hand are made to specifications and indicators of battery or batteries.  

  

• design of the battery requirements

 

Battery is designed to meet the object (or user equipment) made the request. Therefore, when designing the battery, the first to have a detailed understanding of the items on the performance indicators of the battery conditions and user requirements, generally include the following:

 

• the battery voltage;

• Battery operating current is the normal current and peak current;

• Battery working hours, including time to discharge continues, the use of the term or life cycle;

• Battery work environment, including hours of work in which the Dell Latitude D510 battery status and temperature;

• The maximum size of the battery.

 

Should also be taken into consideration: the source material; battery performance, characteristics of the battery of the determinants of battery technology, economic indicators, environmental issues and other factors.

 

• performance assessment battery of key indicators

 

Battery performance in general, mainly the following aspects to evaluate.

 

(1) The capacity of the battery capacity is defined as a rejection of certain conditions, can be obtained from the battery power, which is currently on full time, generally expressed in Ah or mAh, this which directly affects the maximum operating current of the hp Pavilion dv4 battery and working hours.

 

(2) The discharge characteristics and internal resistance characteristics of battery discharge is granted the discharge of the battery in a system, the fineness of its operating voltage, the voltage level of the platform and the performance mainstream discharge, etc., which indicates that the battery with a capacity load. Battery internal resistance including the ohmic resistance and polarization resistance electrochemical discharge current large, the resistance of the flow characteristics are particularly evident.

 

(3) Operating temperature with electrical work environment and conditions require the use of batteries in a specific temperature range with good performance.

 

(4) The storage performance of the storage sony VGP-BPS5 battery for a while because of certain factors for changes in performance, causing the battery to discharge, leakage of electrolyte, the battery short-circuit and so on.

 

(5) life cycle (secondary battery) life cycle means the system of secondary batteries in accordance with a certain load and discharge its functions reduced to a certain level (for example, the initial capacity of 60% ) when the number of cycles.

 

(6) The internal pressure and resistance performance overload (secondary battery) for Ni-Cd, Ni-MH battery and other sealed type secondary, high current for recharging the battery internal pressure can reach the balance and equilibrium pressure of the high and low resistance of the battery current level of overcharging to measure the performance of performance are all important indicators of good or bad, if the battery internal pressure reaches the equilibrium or balance, the pressure is too high, it will limit the devices battery voltage (such as explosions bullet proof) to open the battery caused by discouragement or neglect fluid, which leads rapidly to the failure of the battery. If the device fails, pressure limiting, there may cause cracking of the tank apple iBook G4 14 inch battery or an explosion.

 

2. Battery design the basic steps

 

Battery design staff in design tasks clearly and fully prepared, you can imagine.

 

User requirements depending on battery design ideas from the battery, there are two: one for electrical equipment and instruments, rated capacity of the power source, and another is just one factor given power supply form developed excellent battery performance specifications for new or special-shaped battery.

 

1 to determine the ability of design steps of the battery

 

• determine the number of combined organ cells Tenor battery voltage of single battery and current density.

• According to user requirements to determine the overall work of the battery voltage, current indicators of operating and other series of selected cells, the light of the series “Volt-Ampere curve “(derived from empirical data or experience) to determine the work voltage of single cell and current density.

• determine the number of batteries in a single cell.

= The number of total voltage single battery voltage / battery

• Calculation of battery capacity

• According to the requirements of course work and working time calculations of charge.

Nominal Capacity * = current operating hours

• determine the design capacity of

Design capacity = capacity * Design factor

A design factor is to ensure the reliability and lifetime of the whole of the battery, the general attitude 1.1-1.2

Influx of a large number of companies, but it is followed by a rapid decline in profit margins, current earnings are relatively modest. “According to one press access to information shows that in a few years, the profits of the sector before 100% of profits fell to 5% of profits are low.

 

Moss is the beginning of

 

“In Shenzhen alone, there are hundreds of production companies, all countries should be more than 1000 of the”. Zhi-Ming Zeng said “China’s Sankei Shimbun reporter, although the development of the industry supply lithium just a few years, but the pace of development beyond imagination.

 

Zhi-Ming Zeng worked in Beijing, Anwar Ibrahim on United Energy Technology Co., Ltd., has been witness to this emerging industry since its Laptop battery birth, then quickly dissolved into chaos after the development of the whole process.

 

Beijing Anwar United Energy Technology Co., Ltd in the industry is also a relatively big businesses and claimed to be the best technology for domestic iron phosphate factories producing batteries, the main development, manufacture and marketing of new batteries power rechargeable lithium iron, lithium-ion rechargeable battery and its subsidiary products are widely used in electric vehicles (EB / EV / HEV / PHEV), electric tools, solar, UPS, digital products, products of export to Europe and North America.

 

 

Currently, however, Beijing Hualian contract security industry, like the vast majority of companies is in the common development of the industry to feel the pain of confusion.

 

If Sony in 1992, the company will sell lithium batteries as a starting point for the dates industry. Then, set up by thousands of businesses, there is a sizeable proportion of companies are neck and only 50 million fund has committed more than 10 employees, renting office space, and even BTP-43D1 some minimum level of production equipment has not yet completed its acquisition of haste.

 

“These companies are not standardized operations, directly leads to lower margins on products, currently only a small number of large enterprise customers end because of stability and healthy development.” Zeng Zhi-Ming laments.

 

“2007 years ago, few people realize that the lithium iron phosphate promising, but production of lithium iron phosphate over 100 companies.” Xu Gang, vice-president of Tianjin power of God in the media about the fierce competition in the sector said. “The real business is doing quite well very soon.”

 

Technology Highway

 

According to the industrial chain, the lithium in batteries and produces batteries, Dell Latitude X1 battery materials can be divided into cathode materials, anode materials, membranes and electrolytes. Lithium cobalt oxide, manganese oxide, lithium nickel cobalt manganese-lithium and lithium iron phosphate cathode material for Li-Ion battery technology, the basic material Zeyi graphite anode, solid particles of carbon-based; in positive and negative electrolyte East and diaphragm.

 

The status quo is both manufacturers of lithium battery materials and battery manufacturer, has technical advantages of firms are very small.

 

“The main problem the industry is not competitive and disorder problems, the most critical issue is the price and technology.” Institutional research Frost & Sullivan focused on energy sector analyst Linda again told ” China’s Sankei Shimbun “Report to the United States, Japan and other countries, the Chinese Li-ion hp Pavilion dv4 battery industry, the technology gap is evident.

 

It is understood that companies worldwide have also strengthened their research and application of lithium batteries, but lithium batteries and other current high explosive which remain outstanding and Chinese manufacturers in the most backward in this regard.

 

BYD is a relatively rapid development of industry and enterprises in technology also have the advantage over their peers. BYD propaganda techniques, but actually did not get all the benefits of peer recognition, Zhi-Ming Zeng on BYD lithium battery that is not new, and the United States similar to products similar.

 

Li-ion battery industry has been concerned about the development of wind investment industry, Chen Qiudong also noted the technical level of the industry problem of the poor.

 

Chenqiu Dong said the domestic iron phosphate lithium material is not a company analysis, each doing a half-dozen properties of materials are needed for the overall level is not difficult, but to do this material (in particular, is to watch the processing performance, stability, and discharge broadband sexual characteristics) is not easy.

 

Statistics show that China, Tianjin, Shandong, Zhejiang, China (Jiaxing, Huzhou, Jinhua) and other places enormous investment of many to the sony VGP-BPS2 battery manufacturer Li-ion batteries, the results will die of ‘a natural death, the main technical issues can be resolved. Chenqiu Dong said that with technology partners to find a great association. Many colleges and universities or research institutes, technology is just technology laboratory, far from industrial. Laboratories doing material properties are excellent, but the pilot will encounter great difficulty, even if reluctantly passed the test pass, the stage of mass production industrial, exposing the problem will be even greater . And this is not an isolated phenomenon, but rather a common phenomenon.

 

Linda noted that in addition to technology, the price of lithium high power hamper its rapid implementation is a key factor.

 

For example, a lithium-ion battery electric bike for the price of 1,500 yuan, while the current total price is also an electric bike, but about 2,000 yuan, if electric cars are being lead to the most-assembly acid batteries.

 

“The main reason is the high cost of production is low, there is no scale. If we can balance the production, sale, these costs should be quickly abandoned.”

 

Achieve the same high prices of the deepest reason is still an immature technology, resulting in the production and marketing limits.

 

CITIC Guoan (15.44, 0.25, 1.65%) Mengguli Power Supply Technology Co., Ltd. in Beijing during the Olympics for the 50 pure electric buses in operation provides the necessary batteries, and its technology in the industry considered relatively mature, and even well, its Lu, general manager of its admitted, “synthesis technology of lithium is still a problem.” The stability, consistency of production and life of the technology of lithium batteries is not yet mature.

 

Warlords battle for the throne

 

Warlords battle for the throne, such companies will win?

 

In short, technology is king.

 

On the most critical factor in business development, Zhi-Ming Zeng said the two words “innovation”. He was referring to technological innovation.

 

Linda noted that the company will finally, it must be to solve the problem of toshiba PA3191U-4BRS battery price and technical aspects of the business.

 

Technology, Chen Qiudong consider more comprehensive, he summarized the following three elements: mature technology, a strong management team and excellent resources.

 

Chenqiu Dong said that the three are complementary, we can not do without. There are no mature technology inevitably limit the speed of development, so stay in laboratory techniques, or at least have been at least 2-3 years of exploration, technology and talent are also inseparable After all, the lithium iron phosphate material technology and is not fully mature, the industry has no uniform standard, equipment, materials, processes, and so the real questions should be able to count on people to solve. Without a strong financial strength, even if the materials out of, the corresponding production or management can not keep, they lose opportunities for collaboration with key customers, key technical staff for motivating the team enough, lead loss of human resources. Have no outstanding management team, even the best technology does not produce value here includes the implementation of the said R & D, production management, quality management, marketing and other links for startup companies that are very difficult.

 

However, the company won the healthy development of the apple A1061 battery industry as a whole can not be separated. As CITIC Guoan Mengguli Power Supply Technology Co., Ltd., General Manager of the Lu said: “I am most concerned about is when they can regulate this industry together.”
