Our country is technically in electric vehicle what the bottlenecks, which reached the international advanced level?

 

Ren Chang: It is a very professional issues, electric vehicles are two to five plan years of scientific research and national technology, we first control the electric vehicles of certain technologies, it should say who made considerable progress, we are now above the global integration technology has almost reached the international advanced level, but this can not be close, has not been reached. Our Laptop battery with overseas there is a big difference. The engine, our products, technology and foreign countries there are still gaps.

  

So now the basis of our industry as a whole should be said that, preliminarily to industrialization may do some demonstrations, demonstration of applications, but also can not enter the commercialization phase. It’s a real electric cars in society, in people’s homes there is very, very long distances.

 

Reporter: You said that the electric car is a pure electric vehicle, or all of it?

 

Ren Chang: I speak mostly very pure electric technology, fuel technology is ahead of the technology, Tongji University, the team did a great job, we must say we are in an advanced international level. But now the level of IBM ThinkPad R51 battery electric vehicle technology, fuel price and use it is still a long way from reality. Fuel technology is the high technology end, the electric fuel car is the ultimate goal, but at present we can only do a little cutting-edge technological development.

 

Let me give a simple example. Hybrid, it is the leading product in the world, more importantly, gain full access to the commercial scene is the production was massive, and the user can use as an ordinary car, as is our goal to pursue, but we are currently countries have not yet reached a level where pure electric vehicle.

 

Reporter: battery technology is mentioned bottlenecks do?

 

Ren Chang: First of all is the battery, the gap between us and abroad, also has a large lithium battery is the main direction, but still in early development stage, the level of scale and Abroad there are still significant gaps, particularly in the industrial fuel density, reliability, and we are now able to ensure a cycle of 1000, representing 3 million km, but we at least reach 10 thousand kilometers. In addition, the Dell Inspiron 1525 battery price is too expensive, and domestic about 3 yuan / W, 1 kW to 3 thousand dollars, 20 kW to 60,000 yuan, and now 40-Watt engine may also be necessary for millions of yuan, but can guarantee reliability.

 

In such circumstances, countries have also issued many preferential policies. However, the preferential policy does not mean that the car had been able to produce, and now this policy is mainly directed against the movement of vehicles to transport work to be subsidized. In this sense, the public transport policy in support of state subsidies to make some demos, and no commercial transaction. Purchased for future use can not afford too poor to feed themselves, but the infrastructure is not complete, they have limited its development.

 

Reporter: How can we reduce the gap with foreign countries do?

 

Ren Chang: the gap between us and foreign countries is the main level of technological backwardness. Firstly, to strengthen scientific research, we also conducted a number of times the group of experts from our research is enough investment capital related to R & D, but also and mainly rely on Ministry of Science and allocate special funds to support a number of projects to do. In addition to the government’s foreign policy orientations supportive, companies are also given, and even joint development of business alliances. Therefore, we must first increase the scientific and technological research and development, investment capital increase. Followed by industrial-scale industry of electric cars and the automotive industry both traditional relationships are different, the most important difference is that different from the entire energy sector, industry electric vehicles, including the hp F4809A battery industry, the automotive industry. The automotive industry is not where the engine manufacturer can be installed in the car engine has a lot of specificity, we now have many electrical installations are small businesses, large enterprises disdain and small businesses in the power technology is far enough, entry is also far from sufficient, conditions for production in various fields deviation is very large, relatively speaking, it is also a factor.

 

Then, attach importance to the country will gradually foster emerging industries, increase investment in these technologies support, including venture capital, now encourages the industry to support innovative, energy-related news industry of automotive parts, it is very important. Why fire the new energy sector, because many people are optimistic about this direction. The next step is to direct more state funds in addition to the new energy industry, in batteries, motors, electrical systems, etc. should be increased.

 

Meanwhile, the defense community is also important to promote community awareness of environmental protection, to accept the electric cars. Concept of China and consumption abroad not the same. Pure electric vehicles, especially sony VGP-BPS5 battery electric vehicles are the basic maneuvers from the beginning, the Chinese consumer habits may be very different.

 

Small cars, chinese compared to cars and other state enterprises, technology, energy is not sufficient, the reliability is not good, can not be a great support, but the cost is very high. The small car is the direction of development of electric vehicles, whether China should have its own means.

 

Reporter: The strength of some domestic cars are not as Toyota, Honda, etc, and now that the Alliance Electric Car from China, which is a good way?

 

Ren Chang: I must say that our country after years of experience, and now developed to the Industry Alliance. For example, Chongqing Science and Technology system, which was introduced in innovative alliance of electric cars formed at the same time led by Chongqing Changan Electric Vehicle Industry Alliance, the two alliances that rely on corporate contributions do enough to rely on each enterprise union together.

 

We are of technical innovation and the Alliance, in an alliance where we share resources with each other, and proposed communication system to build the same platform, or understanding of their needs through exchange of the other may increase the level of toshiba PA3285U-2BRS battery research and development can be faster and better development, this can be received in a small, but there are fairly good results.

 

Industry Alliance can work with the support of each plant collaborative development. I can give Chang’an supply batteries to determine the development plan of Chang’an, will the kind of consumer technology, so it will produce 100 thousand, 20 million units so they can spend , so that synergies can be formed into an industrial base more quickly support our OEMs, so that our suppliers to make better products.

 

I personally think that the combination of technology or Industry Alliance is our next major release of the production and research on technology R & D model, which would greatly advance our technological innovation.

 

Reporter: vehicles with new energy in many areas, the future development of new energy vehicles exactly what the process, who feel this way?

 

Ren Chang: should say, these are the countries were very concerned about how secure our online technical state of electric vehicles in the general group of experts held a series of seminars, the state ministries and commissions also organized a special research policy. With national conditions of China and experience in the development of large countries, we now determine the apple A1185 battery electric car is the transformation of the automobile industry of China, the leading direction, which is a lot of ‘Technical Analysis.

 

I think this is the right choice, but because of pure electric vehicle-related technologies can meet market demand, so there is still a long way to go, and each stage has a choice, we have to do transition program, so that if it is done well can be energy efficient, but also to reduce emissions.

 

When the BTP-43D1 battery technology has improved continuously, the cost of falling into the business model of using the larger, thus completing the transition to a pure electric. At one stage may be a direction that is primarily based on our first hybrid may be the main May to 20 years, 30 years later is a pure electric vehicle based. Currently, a more realistic option is a hybrid.

 

Reporter: There are three kinds of hybrids, we mixed in the mixing of light technology in the international community should be at the top, re-mixed with a large gap between Mody?

 

Ren Chang: Light mixed with more mature, less the same level with foreign countries, but it is a vehicle early electrical products, strictly speaking, is not truly representative of the actual development of electric vehicles at the future.

 

Make now a part of the mix and made some achievements, but there are still gaps and abroad. Re-level mixture of products that we are a big difference, and why? Because the automotive industry in China has a very important engine of our technology base is not in our hands of the Chinese people themselves, although many own brand products, technology control engine is a technology engine control is mainly for foreign help to do so, we pay for the Dell RN873 battery technology they produce, the central part of the alien. Therefore, lack of basic technological research led us to re-mixed when the subject of considerable technical limitations. Because he wants to integrate the engine as a whole, we can not make changes to the engine, can not do the depth of integration can not do much optimization can make a few simple integration, If our technical level and a lot of gap. This is an important contradiction of state assets abroad, the brand has these advantages, we chose this advantage over foreign countries, choose the re-mixed with foreign countries that we do not have d ‘ benefits, if we split the maturity of someone else built our maturity, it may be is a more appropriate choice.

 

We pure electric vehicles as China’s transformation of the main direction of choice is the reason, since there was no more than others, we have taken this step, focus on developing pure electric vehicles at the top to make a transition.

 

Reporter: hybrid is far more than the shorter form?

 

Ren Chang: It depends on the maturity and marketing cell HSTNN-LB31 battery technology at what time to meet. The longer the hybrid is more. I think this line is relatively long, later years, perhaps 10 or 20 that large volumes of hybrids on the market. Initially, we considered a motor vehicle internal combustion traditional 40 years, 50 years of depletion of energy resources, but I still constantly find new oil fields, it is also a direction, threatening the supply of ‘energy transmission system is also very important.

Digital battery / No Comments

1. Motor fuel battery hydrogen to promote the constraints

 

While battery vehicle hydrogen fuel in protecting the environment has a great advantage, but it is still in early stages of development. The main factors limiting the development are:

 

(1) Production costs are high: At present, the source of hydrogen is natural gas in general and biogas. In addition, hydrogen and oxygen by electrolysis of water extracted hydrogen separation. The energy can produce electricity from coal or nuclear reactors to generate. Because the extraction of hydrogen consumption of other energy needs, so if the use of coal, natural gas, methane and other hydrocarbon fuels to extract the hydrogen, it will emit greenhouse gases emissions. Using wind and solar power can solve this problem, but the high cost of such a development mode, causing the cost of hydrogen fuel Laptop battery car. In addition, a number of ancillary facilities such as construction of refueling hydrogen have to charge a certain time.

 

(2) The energy density of small and inconvenient storage and transportation: problems of storing hydrogen fuel, there are leaks and gasification of issues, including the blast, quenching, when the fuel of Other issues to resolve.

 

In conclusion, low-polluting hydrogen fuel, however, but the difficulties of storage, there are leaks and gasification of issues, including the blast, quenching, when fuel and other issues to resolve. There are many methods of producing hydrogen, but only in the settlement of its costs, storage issues such as possible after the batch used.

 

2. Accelerate the Promotion of Countermeasures vehicles to hydrogen fuel IBM ThinkPad T40 battery

 

Development suited to national conditions of China, environment friendly, inexpensive and efficient production of large-scale hydrogen

 

According coal resources, China and characteristics which should focus on the development of efficient and low gasification of coal pollution, large-scale centralized hydrogen production, it is necessary to strengthen the process of coal gasification , CO2 capture and sequestration research, and should focus on strengthening the foundations of our country has a certain, with prospects for long-term development of renewable energy technologies for hydrogen. With the Dell Inspiron 8600 battery growing maturity of nuclear technology from China, nuclear power must be controlled and gradually explore production of hydrogen.

 

A. Development of efficient technologies for hydrogen storage

 

At present, the comparative study of China’s storage equipment hydrogen content of active research due to storage of hydrogen under high pressure, nanotubes of carbon storage of hydrogen, storage of the Hydrogen novel compounds of hydrogen storage, carbon storage gel hydrogen, glass microspheres for hydrogen storage, manure, hydrogen storage hydrogen storage of hydrogen and other layered compounds, the current international research and technology development of hydrogen storage, the main aspects of hydrogen storage in metal hydrides, the storage of carbon nanotubes for hydrogen, hydrogen storage and other aspects of complex compounds, have an advantage. In the future should also focus on development of novel metal storage alloy hydrogen storage of carbon nanotubes for hydrogen, high pressure hydrogen storage of liquid storage compounds of hydrogen technologies in the car as the systems of hydrogen storage to explore the layered compounds, hydrogen storage, the hydrogen clathrate hydrate, etc. technology.

 

B. Enhanced hp F4809A battery technology and hydrogen fuel battery vehicles to hydrogen fuel and related infrastructure, research and development

 

The development of a hydrogen economy is an important aspect is to develop energy systems and hydrogen infrastructure of hydrogen energy transportation. In batteries hydrogen fuel, our country could focus on development of high power proton exchange membrane technology for fuel batteries, low temperature oxide technology with fuel battery based technology fuel battery systems integration, the proton exchange membrane technology, electro-catalyst technology, Advanced membrane electrode technology component, not technology-platinum catalyst, while actively exploring bio fuel batteries, regenerative fuel toshiba PA3284U-1BRS battery technology, cold start (Start Cokd) technology research and development.

 

c. The strengthening of the hydrogen and fuel batteries as the core system of energy distribution of hydrogen

 

Because hydrogen and fuel battery has many advantages and features of decentralized energy supply, thereby strengthening the nucleus of hydrogen and fuel battery system of distributed energy has become the focus of research future international and development. The current formula of hydrogen and fuel batteries as the core of the system tends distributed energy development is the use of renewable energies, combined with hydrogen as an apple A1185 battery carrier, to fuel batteries as a tool conversion of energy to enhance the development of renewable energies.

 

d. attention to the economic development of hydrogen-related environmental issues and security

 

While hydrogen itself is a kind of green energy, but in the process of using fossil fuels, hydrogen production, storage technologies, if properly, there will be leaks CO2 in the atmosphere caused by rising greenhouse gas emissions. Hydrogen production, storage, transportation and use of fuel batteries to hydrogen, it is inevitably the process of hydrogen leakage. When released into the immediate environment of the hydrogen reaches a BATCL50L certain concentration, may be encountered by fire or explosion, where a strong chemical reaction, causing casualties and property losses. In addition, leaks in the atmosphere of hydrogen with the reaction of atmospheric ozone, the destruction of the protective layer of ozone in humans. Therefore, we must strengthen the safety-related hydrogen technology and the detection of hydrogen sensor, the potential accident scenarios on research technology.

 

e. effective to encourage companies to participate in hydrogen technology and fuel batteries, industrialization and commercialization of evolution

 

In accordance with the laws governing the functioning of the market economy, hydrogen technology and fuel batteries as the technology is mature, with the case of price competitiveness to win the contract to replace fossil fuels traditional and a number of relatively low efficiency use of methods of energy Dell HD438 battery conversion. It will be possible for firms to participate effectively in the development of hydrogen delivery prices competitive preparation, storage, transport and application technology and this was also the final decision of hydrogen to replace fossil fuels traditional key.

 

f. use government subsidies to promote hydrogen

 

To promote the use of the hydrogen society of the energy required to inform the public of the merits and use of energy security of the hydrogen to promote the understanding and use of the hydrogen energy. Meanwhile, the state should be presented to a policy of encouraging more efficient, for example, the State should be the use of VGP-BPS2B hydrogen government subsidies in order to effectively promote research on hydrogen energy and the development and implementation of the system.

Why the battery life be shortened?

Posted by admin on October 20, 2009
Digital battery / No Comments

The battery of multi-buyers wondered why the battery of my old? After reading the contents of one would understand that we must understand why the capacity of the battery down? “The reasons for the decline in capacity, and why?” “The battery internal resistance will affect the capacity?” We then explain in details.

 

Laptop battery capacity after repeated loading secondary discharge will decline, its causes are complex and diverse, not only after repeated accusation, the discharge capacity will decrease, even long not to use, have the same problem of declining hardware capacity, rather than the charge and repeated the battery is discharged more easily damaged, because the battery is the use of chemicals from the chemical energy into electrical energy products, chemicals to maintain their regular activity and only less than a deterioration of failure, when the original activity of two compounds role of the end or nearly out of season, and will not be able to perform chemical reactions, this time the decrease battery capacity, that is, the cells are already gone, the battery must declare died.

 

Volume decline over time tends to happen when?

 

A good quality of the secondary battery, the continuous load and discharge over 500 times the capacity can reach over 70% even higher, but the decay rate of the IBM FRU 92P1141 battery capacity, plus good or bad depends on the battery cell, based on the battery yet to match the user the use, storage, temperature, remarkable degrees to prolong battery life.

Indeed, although marked as secondary batteries can be reused, but he still has his life there, so laptop battery, for example, the ability to label 4000MAH, but after the charge and discharge its capacity will be successively reduced by one year after the building are more likely to fall into the 3300mAh below, it is a normal phenomenon of secondary batteries, but can also see this problem is actually continues until that the battery technology, the use of both the meaning of love using a usually short period of time, and when using the battery Time is Running Free When this time to replace the battery.

 

What is a voltage difference?

 

Many Li-degradation capacity of ion Dell U4873 battery or failure due to a series within the battery due to voltage difference generated, resulting in cell battery produced the gap between tension can be avoided, because each battery string of battery cells nature can not be exactly the same, with a long time, there are some features of the natural and poor battery before aging, affecting the curve general discharge. It is with gratitude that the aging cell batteries have been the first full charge and discharge has also finished first place, but this time the ability of cells to the other battery is not fully utilized exhausted.

For example: load, others charge the battery kernel boot approaching saturation when the voltage is 4.2 V, while the aging of the battery cell may have been grateful to 4.3 V or a voltage even higher, causing an overload of electrical cords and other costs dissatisfied; discharge, when the strings are always large voltage range of work that is already grateful old battery or battery is already below the normal operating voltage , 3.0V, resulting in a unique string of low voltage protection, forming the hp PP2182D battery to discharge faster.

 

What is battery aging?

 

The aging self-styled drums, which, as the increased frequency of use and time, or long-term investment, leading to the capacity of the storage battery, the progressive deterioration, when battery is only one, the batteries, they will build the capacity reduction, while the group of battery Multi-core set-batteries in parallel, they generate all the associated voltage difference, this time the user is most likely aware, the battery is also clearly shown that over 50%, how suddenly dropped below 10%, and even non – normal shutdown, resulting from the use of time, simply said: aging the battery is a decrease in battery capacity .

 

Aging of the battery cell internal battery do what needs to be changed?

 

The aging batteries, the most frequently observed is the easiest to detect is the change in resistance, the internal resistance of the sony VGP-BPS2 battery when the nucleus is very small factory, but the charge and discharge over a long period, because of electrolyte in the battery, and a swimming pool in electronic activity of chemicals in the lower internal resistance of the whole because of increased electrolyte will gradually repeated load variability of discharge, the resistance will continue increase until the resistance as large as the power of the internal battery is not properly released, a common phenomenon is the mouth of the battery, this time, the battery is the so-called aging and capacity battery will decrease with respect, most of the aging of the battery is because the resistance has been caused in the cause can not be used.

 

Change of battery internal resistance include the following:

 

Changes in the cathode materials

 

The molecular structure of the battery, the positive and negative electrodes can hold rainfall on the hole structure of chemical molecules will gradually with the number of loading and unloading of collapse. Blocking, which is positive and negative active materials, passive, there may even be negative materials are polarized phenomenon, reduces the toshiba PA3383U-1BRS battery charge-discharge process can be free to move the number of ions.

Catalyst for Change

 

A catalytic role in the molecular structure of the catalyst, due to temperature, humidity, storage time, gradually changing its structure and nature of the final can not be catalytic.

 

Electrolyte metamorphic

 

Electrolyte because of the battery after charging and discharging several times, but it was bad, and even the loss, the low quality of basic battery is easier because the composition of the electrolyte under the control of undesirable while the faster deterioration.

 

Conclusion:

 

Again, the apple A1185 battery itself as a kind of oral consumption, with the increase in the number used in the battery charge storage capacity, the successive reduction of life cycle support of about 500 times more than the estimates of the time, if the first few days of use, between about 1-2 years we should move to a new battery a.

But for the laptop. The battery is expensive consumables, many people would say that I try to use less battery, or simply do not need batteries, so there is no life cycle of battery problem, but in fact, a This concept is not always the case is correct, the number of batteries affect the battery life conditions, but not the key, because, as mentioned in this article, the battery’s chemical energy of products will evolve with the passage of time, but to reduce its activity, stood not the same because of self-discharge and lead to an excessive discharge, and loss of activity and damage to the canal, so carefully When you pay attention to your battery at the same time, remember the proper use of batteries, but also the Aspire 3000 battery charge and discharge on a regular basis, so your battery to play a greater efficiency.
