In the past period of time, "new Energy Car "The word frequently exposed, which means that the main driver of a vehicle internal combustion engine has started brewing in the area of a major transformation.
And this wave from the government, research institutions to the car burst out of the collective enterprises in the new energy enthusiasm is a good foam filling the Great Leap Forward was a real down to earth green revolution? The answer is given too early, however, if this connection that the traditional internal combustion engine has become a sunset industry is clearly unrealistic.
Fuel cell cost and safety constraints
A basic recognition by the academic view is that??? Hydrogen Engine Is the ideal target, because hydrogen mainly from the electrolysis of water, while the latter mainly from solar energy, either hybrid or pure electric, does not seem to be more ideal than the recycling method of clean energy.
However, due to the current hydrogen production costs are too high, so the price of vehicles equipped with fuel cells there is raspberry, a small car about 100 million / vehicles, and bus prices are more expensive than in the there are many good alternative to the premise, who willing to spend two to three million U.S. dollars to buy a bus then?
Of course, for fuel cells, the most important issue from the security. July 2003, Toyota recalled their rented six fuel cell vehicles, and announced the postponement of another six fuel cell vehicles Lease The reason is that high-pressure hydrogen storage tank of hydrogen fuel in a leak of hydrogen filling. Almost at the same time, all countries in the fuel cell vehicles are found in the test run of a series of security-related issues, which have made the commercialization of fuel cell vehicles prospect of some remote.
2009 3 25, at the 25th World Conference press conference on electric vehicles, 863 new energy vehicles planned major projects team leader, Head of Department of Automotive Engineering Tsinghua University, confirmed that high-Ming Ouyang kinds of views, in his view, the next step in fuel cells are still being explored, and pure electric cars will bring a more realistic future.
Electric hidden pollution Ouyang Ming high according to claim that China has some advantages of electric car technology, but the electric is the best alternative energy forms, its source can be varied, if the batteries have a breakthrough business model is entirely is feasible. Fans of this view, the obviously includes a lot of heavyweights, Chinese Academy of Engineering, Electric Vehicle Association of Asia Pacific and President of CC Chan, Chinese Academy of Sciences Zuoxiu think electric cars will become dominant in the foreseeable future direction.
Professor of Beijing Institute of Technology, 863 electric vehicles, the charge of major projects, Lin Cheng also recognized the drive way pure electric vehicles, he believes that the long run, infrastructure is good enough, pure electric will spread.
"With China's hydropower, wind power, solar power generation in the development of these green, electric cars will become an important step-type energy storage device, the future society must be the transport and stationary energy systems harmonization, which is human the dream. "Ouyang Ming is depicted a high-efficient development, clean and well-ordered society in the future, and this brings us to another are still debating the issue??? If you use the link from the perspective of pure electric vehicles, can indeed achieve zero emissions, but mainly by thermal power plants in China, will cause more pollution at the source?
"From the perspective of energy efficiency, the traditional gasoline and Diesel engine From well to tank efficiency of the final 15%, while the electric car from the efficient use of coal to electricity is about double. From the emissions point of view, traditional fuel vehicle emissions in urban centers, while the source of electric drive vehicle emissions in power plants, in general, power plants away from urban areas, the direct human health threats can be ignored. "Ouyang Ming Gao said," Of course, despite the focus can be fixed the way to deal with pollution, but coal is obviously still a problem. "
Another problem is how to deal with pollution caused by discarded batteries. Even if the pollution away, whether from the perspective of looking for alternative energy, battery technology remains a constraint in achieving the industrialization of the bottleneck, whether it is more than the car battery power, specific energy, cycle number or length of time spent charging exist in key indicators the problem. Another electric vehicle charging facilities also face the problem, which needs government planning, as most apartment buildings in China, the charge on an issue, it need government support in infrastructure.
