Best laptop battery

In the double pressure of energy and the environment, global automakers will look towards a new energy vehicles, huge sums of money for technical research & D and marketing applications. Among them, cell vehicles to hydrogen fuel as an energy source has been one of development. Recently, however, laptop battery rechargeable  Automotive Engineering, Tsinghua University and Development Research Institute, Mr. Song Jian, Vice-President stressed that the high cost of vehicle fuel cell, hydrogen is difficult, the technology of fuel cells for development of new energy vehicles does not seem practical.
Deficient in several respects:
The high cost of vehicles to hydrogen fuel cell is difficult
Vehicle fuel cell operating principle is: always sent by the fuel cell hydrogen fuel and oxygen under the influence of the catalyst in water while producing electricity driven generator to drive the wheels turning. Although this new energy vehicles emit virtually zero, but due Song, costs are high, restricting future development of hydrogen is difficult.
“Fuel cell in the car can not replace anything, just a device for converting energy, is equivalent to the rising cost of cars.” Song said: “The current generation technology of fuel cells, the price per kilowatt-General to $ 20,000 U.S.. Even in 2035 before the older generation, but also the price per kilowatt of about 20,000 yuan. “total cost of more expensive vehicles, one year for use during the Olympics, no large-scale production of fuel cell version of the Passat, for example, dell e1505 battery  the cost may be nearly one million yuan each. “Vehicle fuel cell is still in the ‘Run Model’ State, at home and abroad are not mass production. “Said Song.
In addition to manufacturing costs are high, the hydrogen is also difficult for low-cost access to one of the problems encountered. Song said: “At this hydrogen by electrolysis of water: the acquisition, use a high cost. Because it is gas, there is a huge and difficult, it is difficult to store and transport. And even in the small spark of static electricity can easily ignite under, there are a security risk. ”
Best Uses:
The most appropriate storage of solar wind
The technology of fuel cells for the development of new energy vehicles does not seem practical. But Song made, using similar techniques to construct the station energy storage power, stabilize the voltage, frequency, regulate peak electricity and the valley, but it added a good choice.
“Wind energy, solar energy by the excellent weather conditions and volatile output, if they are directly integrated into the grid, would damage the quality of food.” He explained, “it would better as a fuel conversion device cells, wind energy, energy issues Solar Electric in situ electrolysis of water into hydrogen and oxygen, then through the fuel cell to generate the electricity. it would lead to the voltage stability of power, frequency stability,  hp dv9000 battery  and better suited to enter the gate. when hydrogen becomes a storage medium for energy. ”
Song also said that, initially designed for generators to power fuel cell car, has the characteristics of fast start, can not simply be used to adjust peak and valley. Consumption in the trough, to ensure energy efficiency, excess capacity may be the first store. Wait until rush hour, just 12 seconds of time, fuel cells can bring electricity to be released.
As the current high cost of fuel cells and abroad have not used it as an attempt of energy storage power plants.
New energy cars:
Hybrid is not enough People First
So all kinds of vehicles in which new energy development in the future? In this regard, Song believes that the prospect of a better hybrid.
He said that pure electric vehicles are powered by the vehicle power supply, rely solely on battery power, while leading the process emissions to zero, but very expensive, if long distance travel, the charge is not very practical. The bio-fuel vehicles do not have universal significance, the system needs to take the use of ethanol fuel from corn, soybeans and other crops could cause a food crisis. In contrast, the hybrid technology in foreign countries has matured. It will save over 40% of fuel consumption, 6.2-liter engine consumption of fuel amounts to only 3 liters of fuel consumption average.
However, this song has also stressed that despite the prospect of a good hybrid, but for now, for the average consumer is still very wasteful. He remembered that the GUI for calculating the price of hybrid vehicles that average savings of 1 million dollars, also the equivalent of 7 million yuan. sony bps2 battery   Even if the oil price of 7 yuan per liter for the calculation, it can buy 70,000 yuan 10,000 liters of gasoline, enough for passenger cars and 130,000 -15 thousand miles. If you put a one-time purchase of a car so even if the fuel hybrid high yield of 40%, still need to take 60% of the fuel load.
