OR pure electric vehicles hybrid vehicles

 China's auto industry in recent years about the topic, it is natural that involves electric vehicles, energy conservation and so on, we talk about, everyone talks about engaging in the car, the car can not engage in talks, the atmosphere is quite the excitement!
I am also very excited always such people who talk about one, but I was think about how I began to care about this is so, , is a teacher who let us care about them, because the college major projects are generally related to this, Tracing the source or the national leadership, the experts very seriously, think this thing is good. my people have a wrong, love thinking, and analysis of motivation. In I see it, the state encourages the development of these new energy vehicles original intention of the policy is fair and reasonable manner.
Why? First, our country is indeed so much, do not save energy can not stand, oil control in the hands of Americans, If we do not find some way out many, always see people face to, so unhappy! Second, seeing China's auto production and sales ranked first in the world, the automotive industry is too important to our country, not just pull the GDP , also provides a lot of work, the attitude of our people is very clear, China's auto industry must be strong! Third, China's auto manufacturers are able to build cars, selling cars is not bad, but it is a pity, not a core technology in the real car the biggest names in children can be and are competing with international car, and basically people minds, our hands, people eat meat, we have soup. some corporate executives who eat a soup can also be satisfied, but the people are not happy, critical voices . SOEs are holding the good wishes of the market for technology, they end up with the biggest names in children pro-think that we are equal, did not think people wrong thing, when you are a small daughter, pre-marital property be notarized. Market Well, take a; technology Well, the production technology is also a technical ah! I know this is rather cynical, sarcastic we over some state-owned enterprises, state-owned enterprises leaders of our heart than I know, they are always fighting, but unfortunately too cunning foreigners, we do not have experience, vulnerability to them have been drilled, to now this situation is helpless ah! national leaders see this situation, although it can not be reconciled, but the heart also understand the core technology in the traditional areas of automotive, to seek to help people to take the initiative we , the idea is too naive; but his entire right, too costly, does not pay. new energy vehicles, is a trend that we and the biggest names in children have the same starting line, it's worth a fight to fight.
Ever since, the state development of new energy a high degree of technology a national strategy, vigorously support, along with the various funds, various grants, with the next, according to our old tradition of the Red Army, decision is in favor of the table with both hands. But, I must say were, however, all directions are on the up?
said the country to encourage new energy industry development policy, I would like to cite one example, is our vigorous optoelectronics industry. It is very clean solar energy from the sun, similar to the endless, the development of this new energy seems to be of touch. With the encouragement of policies related to the introduction of various places, a new Energy and Industrial Park where they stand , China's photovoltaic industry production capacity ranks first in the world instantly. see this message, some people may very excited, but the reality is indeed frustrating. optoelectronics industry is the core of the polysilicon plate, something that can be sold for each of 2007 kg $ 500,cheap UGG boots, foreign manufacturers production costs 30 U.S. dollars per kg also is simply profiteering ah! swarm of China's enterprises, there is no production of polycrystalline silicon core technology to direct higher price of foreign equipment, the cost per kilogram can be controlled 50 to 70 dollars, or make some, ah, did not expect to wait until the capacity of our enterprises coming up quickly from the polysilicon 500 U.S. dollars per kg fell 50 dollars, all of a sudden we perplexing, more production, the more you lose , and polysilicon production process will produce a large number of hydrogen silicon tetrachloride, is a serious pollution to the environment, others with very cheap price to buy our production of polysilicon, we not only lose the environment paying the money paid out is really a lose-lose ah! pull this topic far from the point, I just want to point out potential new energy vehicles will pursue the direction of master key technology, or else the end will be for naught.
recently read the news network, see a CPPCC member shouted in the Assembly, we should vigorously promote the process of pure electric car industry, I really worry ah. Science is not to engage in the Great Leap Forward!
I have received information from the point of view, as if using a new energy , whether lithium batteries, iron battery, fuel cell,UGG boots, hybrid, as long as the car used in the national policy to support. I think this is very wrong, so do not focus on the full range of investment, better concentrate on the most significant breakthrough. And in considering this issue, not just stand the energy point of view, have to stand in the car point of view. My view is that national policy should focus on hybrid vehicle technologies related to the following reasons:
1, mature battery technology.
currently used in battery electric vehicles to mainly lithium and lithium iron phosphate. These solid battery charge time, durability, driving range with the existing traditional power have a larger gap. the current battery technology is still insufficient to meet demand for cars, in my opinion the existing battery technology product created by the water can not be counted as pure electric vehicles on the true meaning of a Notes to to sum up: He asked me dare not go out I speak more pessimistic, unless a revolutionary breakthrough in battery technology, or to optimize existing battery technology to meet the requirements of the car is likely to suffer thankless.
2, the immaturity of fuel cell technology.
Fuel cell vehicles has been a very popular topic, but recently seems to have come to mention less, and our school's research and development in fuel cell vehicles has been put into large, relatively long time, and I have been very optimistic about it, I always believed that it is to deal with the future final solution to the oil crisis, but the current fuel cell technology, a lot of problems and difficulties,UGG bailey button, to fruition in a day, we have to be patient it can not succeed in it, we can not just Wait, you also need to find other viable options.
3, hybrid vehicles and automotive R & D breakthroughs in core technologies.
car the final analysis, the core technology components of the core technology, a large number of parts in the car , the most important thing in the engine, transmission and suspension system, and precisely in these three areas of China can not compete with foreign auto giants. engine control technology is completely Bosch, Delphi and other parts giant monopoly, and our automated Transmission technologies relies entirely on imported technology in the core suspension active suspension control technology we have no control. I always have an idea, through the whole technology of hybrid electric vehicle research and development, breaking the three bottlenecks.
first On the suspension, because I was doing with the active suspension-related issues, and I do all this with the existing suspension active suspension systems are different, of course, no textbooks, it also has a feature vibration energy can be recovered, now my goal is to produce the energy it can drive the car all the electrical load, although we have not succeeded in the trial, but I still have more confidence in it.
and then talk about the transmission, currently on the market a variety of automatic transmission, I'm not optimistic, either AT, CVT, or DCT, are destined to be eliminated, we study the specific technology, automobile, do not follow the crowd, first think about before action, do not Some obvious defects in energy technology investment. these automatic transmission each have their own problems, such as the AT will increase automobile energy consumption, and the stall is limited, can not make the car work on the ideal power curve; and CVT is called the failure of failure, in principle there is a problem, CVT is the core of a V-type belts, changing the speed ratio, changing the distance between pulley to change the rotation radius of the belt, conveyor belt in the pulley in order to slide freely, I hope friction with the belt pulley smaller the better, but they hope to transfer torque between the pulley and the belt has some friction, which makes these two conflicting factors that are associated with a small slope associated pulley , this is irrational, this is the reason for the limitations of CVT applications, I think that will change the speed ratio transmission with the transmission torque of these two important functions together is no future to. DCT dual-clutch gearbox that is on the energy consumption AT is superior than some, but the nature of the transmission gear is limited, not very ideal, and many of its parts, control complex, expensive, its not my cold. In fact, I personally very optimistic about IVT, which is super- torus transmission, this thing is very few parts and can continuously change the speed ratio, and torque control can be true, that is how much the wheels to provide much, perfect in all respects. This thing seems to domestic of very few people, I checked the world only two companies in Japan and the UK are doing, to be honest I do not believe that the world's auto giants do not know this thing, I guess they want to first of these AT, CVT sell enough of the talk about it, until we put them to buy the old product line, and again and again new and better technology, letting you blindsided!
final say in the engine, I was in a major international auto parts internship part time, doing this type of engine calibration work, to be honest I do not think that independent research and development to master engine control technology is a good idea. I was doing during the engine calibration standard quantitative access to the engine to reach more than eight thousand articles the vast majority of parameters are discrete the need to come through the test, and there are complex links between the others for hundreds of years may precipitate a joke. the majority of our auto companies are not the courage to bite the piece of bone , then the school does not have sufficient financial resources and capacity to do, even if efforts to do, and what other people have not compared the competitiveness.
However, if it is based on hybrid vehicles, but added there is a way. In my opinion , China's major universities, research institutes carry out research and development of hybrid cars are essentially unsuccessful, because we are the engine of hybrid vehicles in the no control, if not with the biggest names in children to cooperate with these engines, and that hybrid the working status of the car engine only by guess, to do things out of strange to have a practical use; of course, is the biggest names in children are very happy to provide technical support for us, and some are even free of charge, because once we developed , or only to them to buy the engine control technology, turned over 90% of its profits, then what the core technology to speak of! In fact, from another angle, in hybrid car, why should we need them to do?
automotive engine now more complex, because the car's working condition is very complex, engine power only in order to meet the car and economy in the choice,UGG boots clearance, coupled with the very complex engine control technology, making it seem unattainable. But for the mixed vehicle, the engine much easier working conditions, the engine's main job is to provide the most efficient power, as a variety of changes in road speed conditions on the motor to be done, in this context, can for Hybrid Electric Vehicle R & D a very simple engine, require less calibration can be achieved with fewer test their control, then the hybrid car engine control master the core technology is not dream.
Summing up above, I think that the domestic automotive professional colleges and universities, research should focus on hybrid vehicle technology, especially related to key parts of the development of core technologies, such as hybrid electric vehicle with a simple engine, fed and IVT can type automatic transmission, active suspension, so that hybrid cars in China is technically not controlled by others, and overall technical performance can go beyond the traditional cars, the world's auto giants to break the core of key technologies in the automobile monopoly, the only way we can be truly independent brand car with core competitiveness, China to become a true automotive power.
