The development of a super capacitor car problems
August 28 this year, and many are used to 11 tram ride to Shanghai residents suddenly found that a beautiful white and green of the new trams to replace the old tram which they are familiar. The new tram is very eye-catching in appearance alone, without the traditional long tram of that two "big braids," gives an alternative feel. Half-way charging time of 30 seconds, you can run 3-8 miles on a single charge, the maximum speed of 44 kilometers, energy consumption cost of only 33% of car fuel in the braking energy recovery when braking up to 40%, independent research and development, with more than 20 core intellectual property ... ... more falling one shy of the data.
It is the Shanghai Science and Technology, "mountain climbing Plan of Action" major research project --- super capacitor bus tram.
11 road model line opened to traffic, marking China's independent intellectual property rights with a super capacitor bus tram a real sense of the world's first commercial operation, the capacitance of the Sheung A total of 10 cars.
"Shanghai using the super capacitor bus trams, electric trolley buses will be cut 'big queue'," "Shanghai Century Train To Face" ... ... a time, this new type of public transportation tram has become the star of Shanghai people's eyes, people were pleased that the clutter The "spider's web" disappeared from the city over the day be far away, and that they favor a "green transport" - the tram will not become a forever memory.
However, after a brief delight, surprise and admiration, and as many Shanghai people are starting to get suited up and are even complaining, not enough skilled pilot operation, charging equipment location was diverted to a sudden cooling does not lead to timely suspension of service on speed Pianman and air-conditioning issues such as excessive noise attracted some public arena. "As the general public, the technical things we do not understand, but also not too concerned about, and we just want to travel convenience." Ms. Lee to work by bus every day, her point of view is very typical.
"No braid trams running three days Lay 3", "promotion may be more difficult," and so on, some of the media and therefore in a prominent position on the commercial operation of such vehicles and promotion prospects in doubt.
Super Capacitor Bus trams can be described as ill-begotten, in the initial commercial operation in the face of "Growing Pains."

Problem does not lies in the core technology
For ordinary people, the trip's biggest wish is convenient, fast and comfortable, there are not satisfied with the sound normal.
So, the problem lies in where? Is it the core technology, but off?
The face of challenge, tram transformation core technology research and development while those seem well-thought.
On Haiao Wei Technology Development Co., Ltd general manager of major projects of National 863 electric vehicles, super-capacitors task force leaders-hua LI, said: "Our confidence mainly from the super capacitor used in power train products - super capacitor product itself . "
According to hua LI introduced the latest addition to a complete car computer-controlled variable frequency speed regulation system, the biggest feature is installed at the bottom of a super capacitor. Super-capacitor (electrochemical capacitor) is between traditional physical between the electrolytic capacitors and batteries, a new energy storage device, known as the world's most cutting-edge green energy products.
     Usual capacitance, is charging a long time, instantaneous discharge; ordinary chemical batteries, power is small, short life cycle, are not available for the tram. The super-capacitor, that is, a lot can be quickly charged, continuous discharge, to meet the needs of the tram road.
In addition, the AoWei developed super-capacitors with high power density, charge and discharge time is short, high efficiency, long service life, less maintenance, application of a wide temperature range, clean environment, no secondary pollution, etc., the main technical indicators such as specific energy, than the power, have already reached or exceeded the international advanced level. As of the end of 2005 to declare a total of 20 patents, including 13 invention patents, utility model patents, 6, an international patent application for a registered trademark.
Shanghai Bureau of Transportation-related person in charge said that as 11 capacitance car is still a pilot project, but as a new thing can not be perfect, super capacitor car there all kinds of minor problems, are also normal.
"The problem mainly at the operational level." Yi-Ping Li, Shanghai Science and Technology Commission, said in an interview that this operation has shown some of the problem is that in a complex road running teething problems, such as charging devices to set off from the site near is vulnerable to the effects of other vehicles can not stop charging; can not guarantee that every point in time due to charge a single charge is often time-consuming to reach 1-2 minutes, more than a single charge of its theoretical value of 30 seconds; slow mainly because of car driver on the capacitance caused by the operating system are not familiar with, and therefore this appears to run in the process of the inconvenience is not a fatal weakness.
"I believe that these problems will gradually be resolved in practice, people should be tolerant attitude towards innovation." Yi-Ping Li to say this sentence was clearly aggravated tone.

"Green Century" Green Bus of the main
On the super capacitor value of commercial operation of trams, Yi-Ping Li spoke highly of. In his view, the super capacitor bus tram tram opened in the prelude to the revolution, and thus for urban public transport systems and the development of the automotive industry have a huge directional significance.
Trams operating in China with nearly a hundred years of history, with its zero-emission exhaust, low noise, as well as the use of clean, cheap energy benefits, known as "green traffic." But the trolley bus overhead line "visual pollution", "poor mobility," "planning problems" are increasingly facing in our out, and some cities have implemented "electric steam reform project", while others are simply removed the line network.
It is reported that in 1989 China's electric trolley buses has grown to 26 cities, there are 4794 in the operation, 3.0 billion passenger trips each year, accounting for 6.7% of the total bus trolleybus assumed 11% of passenger traffic. Up to now there is a trolley bus operated by the National City from 26 down to 18, vehicles reduced by 30%, 46% reduction in passenger traffic, accounting for the proportion of buses from 7.1% to 1.5%, this phenomenon and oil tension and pressure of the urban environment protection and social development reality is far from proportionate.
-Hua LI, said the new buses running on super capacitor is zero pollution, energy-saving and efficient environmental protection, new public transport system to thoroughly solve three major problems of the traditional tram. Tongji University Automotive College Zhuo-Ping Yu also believes that the super capacitor car conforms to China's energy development direction to solve the energy shortage and environmental pollution problems and the ideal solution for a realistic way, but also Shanghai's development requirements.
Hua LI said that from a global perspective, along with environmental awareness and the growing energy crisis, sixties and seventies of last century to gradually reduce or even abolish the trolleybus back to town. In Moscow, San Francisco, Milan, Vancouver, etc. Many well-known cities in Europe and the United States, electric trolley buses have become the main force of urban public transport. There trolley bus known as the Kingdom of Russia, the National tram there were as many as 80000; the United States has now restored the sixties and seventies, out of the tram; Hiroshima, Japan, clearly stated the tram priority.
In China, Beijing, Shanghai, Guangzhou, Nanjing and other cities began to re-evaluate and understanding of trolley buses, trolley buses has increased the intensity of investment and construction. Experts predict that the trolleybus will become a "green century" known as the 21st century the main conventional urban green bus.

No 10, can hardly be in the future thousands of cars
The industry believes that the present situation, the promotion of a super capacitor car still has some difficulty, the greatest difficulty, vehicle upgrades and infrastructure improvements to public transport operators financing the construction of enterprises. From the vehicle costs, the trolley buses and fuel trucks and ordinary compared to the vehicle cost of the tram super capacitor 1 times higher. But its energy recovery, operation and maintenance costs, the system in terms of the landscape there is a huge advantage, especially when compared with the fuel truck, as well as zero-pollution environmental advantages. Moreover, with the increasing number of market applications, the price is expected to decline.
"If you do not have 10, there will be thousands of cars in the future!" Shanghai Science and Technology Social Development, the Director of Ma hair looked confident.
