"Moses," the more the pain of notebook batteries
Continued listing of a variety of new notebooks, manufacturers have started the price boom, 2005 is bound to be popular notebook computers a year. However, along with the civilians of notebook computers, the number of people with laptops a1078 battery, a1148 battery, apple powerbook g415 inch battery, and in the use of the problems has also grown. We often hear in addition to easy to complain about dirty, easy to scratch, the problem of poor heat dissipation, so that users are the most trouble, the biggest problem is the notebook battery. Notebook hardware configuration increasing the consumption of batteries is also growing to become a black hole notebook power consumption. And notebook computer batteries since lithium batteries are widely used after the still has not been any major technological breakthroughs, making the vast number of notebook batteries as a pain in the hearts of notebook users.
Books have to move forward with
Laptop mobile office is the largest from the desktop features, if they lose this advantage, the value of the notebook on a greatly reduced. With the aging of notebook batteries, a lot of the old notebook users have to rack their brains to maintain the life of the notebook. Is not only a variety of ways to try to "maintain" the battery, but also efforts to reduce internal energy consumption of books, however, can not be changed in any case have to cherish the time becoming shorter and shorter battery life destiny.
Notebook batteries because of the relative number of charge-discharge is a relatively fixed, so the factory since its failure to start the process of charging the capacity of each of its performance with the increase in the number of charge-discharge capacity is gradually reduced, and even after a long high-frequency time after time the battery charge and discharge capacity will drop to a fraction of the original.
Old books, buy the battery is not easy
Some users of the old books have been aging original battery was a dead letter, but the market has been very difficult to find a match with original equipment batteries. So some of my friends began to replace the battery through the batteries to achieve the purpose of extension of battery life. Notebook batteries are generally used ultrasonic welding, there is no gap, it is difficult to open, even if the hardware has been opened it is very difficult to close. And many have an internal battery protection circuit, if the time to replace batteries, careless damage to this circuit will lead to disastrous consequences. Therefore, the replacement of their own, or are looking for spot welding equipment, maintenance personnel, there are battery-for-core security risks, as caused by the replacement of batteries notebook a1175 battery, apple macbook pro15 battery burned a few cases.
Range of new users the price is too high
New users of the life of the notebook is getting higher and higher capacity requirements, a battery has been very difficult to meet the needs of use. Typically, we first think of is to buy a piece of original equipment batteries. Original battery price is very expensive, generally around 1000-1500, had to feel the price range is too high. In addition, notebook batteries are subsidiary parts, many dealers will not have the cash notebooks, consumers have become the issue of purchase. Most provide only predetermined, but the price target is not identified. Forced circumstances, will only allow a business to make the , God Who can not buy, only to come it!
Battery can not share resources
Bitten by teeth, the heart of hate on a piece of original equipment batteries to buy, they found a lot of money, but also brought new hardships. Irregular shape, to bring together more than inconvenient, do not use between two batteries of continuity, replace the battery shuts down each time. Different brands, different models of notebook battery can not be generic, this also gave the company a lot of problems users. Usually has many different notebook models, when a book needs no electricity at the same time, mobile office, the various models of notebook batteries are not universal, not only affects the work and an enormous waste of resources; and if to each books are the second block with original battery, the company will be spending a small fortune.
Surprise! The emergence of smart battery
Not long ago, the market there is a smart a1079 battery, m8416g/a battery, apple ibook g414-inch battery notebook for the vast number of notebook users to cure the pain of the battery provides a solution. This laptop battery mobile WAN Zhaoze not small size, light weight, the same capacity, the original battery life than a lot of strong, power supply period is about 1.2 to the original power 1.5 times. And as long as the notebook's power supply or battery voltage at the battery voltage range, can be used. The smart battery technology used to automatically identify the voltage received by the notebook, and automatically adjusted to match the voltage, thus ensuring that the majority of compatible notebook models. Whether it is the old user or new user, regardless of the aging of the battery or the need for a longer period of life, the smart battery is a good choice, and cheaper prices than the original battery a lot. There are the front-end battery power display, you can use at any time to grasp the extent of.
It is said, will be released shortly after the application of a variety of digital products in the battery - with a multi-functional adaptive properties of the smart battery can be recharged in accordance with automatic identification of different items, and supply / charger. Can be used with a battery that the phone, MP3, DC, DV, notebook and other digital products provide the impetus. It seems the current WAN Zhaoze The mobile notebook battery lithium battery is only a step to the beginning of intelligent, but the important thing is this product now has to meet the needs of the majority of notebook users, as multi-purpose or universal smart battery is believed that the forthcoming arrival.

What a piece of the battery can be subversive
The steam engine to replace the animal to change the speed of human perception of the original; internal combustion engine out of the steam engine, an extension of the human experience for the new space; and the next challenge of technological change inherent in gene have been hidden in us. Although no need, but you can imagine the car can also be discharged to water it edible?
June 2005, a Honda City Hall Plaza in San Francisco slowly around the road trip. Honda has carried on its good quality, this silver sedan form dynamic fashion, interior refinement, safety, and driving comfort. The car's biggest selling point is that emitted "water" can get clean water to drink when eating;
You travel outside of the laptop battery has a short storage time and trouble?

And your hands and the world which mobile phone to maintain communication as dynamic multiplier: Finland's Nokia in 2004 released a headset for Bluetooth mobile phone samples to help mobile phone users to call up to ten consecutive half-hour stand-up 84 hours.
All these changes are due to take place in a small volume of container on the scientific and technological revolution - the fuel cell. It can be installed in new cars, the high-speed operation of the notebook computer dell inspiron 600m battery, dell latitude d500 battery, dell latitude d505 battery, dell latitude d510 battery can also be built into the Nokia Bluetooth headset in mobile phones.
Source of power revolution
As early as 1839, WilliamGrove Sir electrolysis of water through the reverse process and found that the principle of the fuel cell. 60 In the early 20th century, as the aerospace and defense needs, the development of small-scale liquid hydrogen and liquid oxygen fuel cells, used in space flight and submarine in 1960, "Apollo" spacecraft landing on the moon using the fuel cell. In recent years, due to the lack of a one-time energy and environmental protection of the outstanding requirements of the development and utilization of new clean renewable energy. Fuel cell energy conversion efficiency due to high environmental pollution by the advantages of small countries in the world of universal importance.
Motor vehicles are an important fuel cell applications. Fuel cell vehicles do not involve the combustion process, no mechanical wear and tear, fuel efficient plane nearly four times higher, than the traditional security of the car much higher. As a result of this there is no tradition of automobile engines, transmissions and mechanical transmission device, just installed in the chassis by the hydrogen fuel tank and the composition of a new type of battery-driven devices, the purchase of fuel cell vehicles that actually buy the chassis, the owner can put on your favorite shell, composed of a variety of models will be able to facilitate a like-for-as simple as a coat.
Honda cars in the car in San Francisco City Hall Plaza, on the road and the line slowly, the world's largest exhibition of fuel cell vehicles in the United States opened in San Francisco City Hall Plaza, on display from the world's eight major auto manufacturers research and development of 23 zero pollution prototype fuel cell vehicles, including models in the range of speed, driving distance, safety and comfort and so close to the traditional car.
At the same time, Japan's largest cell phone manufacturer NEC Corporation is developing a nano-technology and the use of methanol fuel cells, the company said that this battery is the energy reserves of ordinary lithium batteries 10 times, which means that users in a months without charge on the cell phone, or the use of continuous 24-hour laptop. Once the cell phones and laptop computers can work for so long, then even if the long journey, you are familiar with e-life and you can also always accompanied by a.
The concept of these new environmentally friendly fuel cell vehicles and the emergence of mobile phones and the rapid development of fuel cell technology are inseparable. In 1859 invented the first practical storage battery of the French physicist belang Taiwan is in any case can not imagine that 140 years after the battery energy storage can achieve nearly mA per gram level of discharge; even he can not imagine that such a high-energy dell latitude d520 battery, dell latitude d600 battery, dell latitude d610 battery technology still can not meet the current era of power consumption electronic devices need. With the rapid development of the global economy, as well as mobile phones, notebook computers, digital cameras, video cameras, automobiles and other products on the new, highly efficient, environmentally-friendly materials, energy demand, the traditional battery has long been an obstacle to development.
Fuel-cell batteries with ordinary biggest difference lies in the fact that ordinary battery chemical energy stored in the battery's internal chemical substances, when the battery work, these limited reaction material will be stored chemical energy into electrical energy, until all of these chemicals reaction, so common is a limited battery power output and storage devices.
The fuel cell is an open device. Required to participate in the fuel cell chemical reaction between hydrogen and oxygen, respectively, from the external fuel cell to provide a separate storage system, so as long as they can to ensure that hydrogen and oxygen reactants (fuel) supply, fuel cells can continuously produce electricity.
Environment, Stanford University, Associate Professor Mark Jacobson, who in "Nature" magazine: if the United States is now replaced all the motor vehicle hydrogen fuel cell vehicles, from two aspects of the environment and health to improve people's quality of life can reduce the number of people died of pollution and the health of the whole society to save expenditure and consumer spending.
Therefore, it was caused by the fuel cell with two of the greatest invention of the industrial revolution of the steam engine and internal combustion engine comparable to that of resolving the "energy shortage" and "pollution" of these two great world problems is of great significance, is the meaning of the new energy revolution energy power generation system. Assistant U.S. fossil energy said: "The fuel cell technology in the 21st century, half of the impact of the technical, would be similar to half of the 20th century, the role of the internal combustion engine."
Japanese Prime Minister Junichiro Koizumi has also been Saying: "fuel cell so that we found the open door of the key hydrogen energy era." Koizumi's new home in their own home to install a fuel cell power generation system.
The eve of the commercialization of
In recent years, with fuel cell breakthroughs in key technologies, cost reduction, this is not pollution, quiet, efficient and in line with the trend of today's environmentally-friendly way of new generation attracted many international well-known oil companies, power companies and automobile companies and handset manufacturers began to take part in fuel cell technology research and product development in the world, expects to market fuel cell commercialization and road. Application of fuel cells mainly in the electricity, the three major areas of communications and automotive.
For car manufacturers, fuel cell vehicles means that a huge future business opportunities, the world's major automobile manufacturers are involved in this competition. Ballard Power Systems, the United States in 1993 developed the first concept car, the German Daimler - Benz also followed from 1994 to 1997 in one billion U.S. dollars invested heavily in the development of fuel cell vehicle, introduced 3 years four models gd761 battery, kd476 battery, td347 battery, dell inspiron 1501 battery. Until now, Japan's Honda, Toyota, Mitsubishi, Mazda, Ford, GM and the United States have developed a variety of fuel cell vehicles to the operational phase of the model.
Although the application of fuel cells getting better, but too big for its original volume, high cost of continued difficult to resolve such issues as hydrogen to fuel cell commercialization in the eve of the long-term, and as a breakthrough in key technologies, some companies have come on the initial stages of commercialization.
Toshiba has been the fuel cell R & D and commercialization of the pacemaker. Toshiba Corporation in 2004 to develop direct methanol fuel cell as the world's smallest fuel cell to enter the "Guinness Book of Records." Toshiba said that they are optimized, the reliability of these efforts, the expectations of their performance. According to Toshiba's announcement that Toshiba will be the end of 2005 will be a large number of practical fuel cells to market, the main object-oriented applications including small electronic devices, such as small audio players, wireless devices, portable headphones, etc. .
Japan's largest telecom operator NTT Do-CoMo Institute in cooperation with Fujitsu to develop a methanol fuel cell as the driving force of the new 3G mobile phones, has recently displayed new products in Tokyo. NTT said that the models call for as long as eight hours for the traditional models of 3 times.
In automotive fuel cell full of competition, notably Toyota, Honda the two companies. Toyota and Honda fuel cell vehicles has been to the market. It is reported that a fuel cell vehicle manufacturing cost is about the cost of an ordinary internal combustion engine car about 100 times, only those listed for the bulk of the models can produce economic benefits, but its cost is still the "ordinary" car costs 10 times the current price of the Honda FCX each in about 1.5 million U.S. dollars.
Japanese Economy, Trade and Industry announced in a clear vision developed in phases to achieve the practical use of fuel cell goal. The Japanese government plans to invest 11 billion U.S. dollars, in 2010 the national fuel cell vehicles to reach 50,000.
"Some of Japan's plan was too optimistic, the commercialization of fuel cells will take some time, but this is in one direction." China's commercialization of fuel cell bus demonstration national project coordinator, said King Kwong Lun. It is reported that during the 2008 Olympic Games, China will also be a fuel cell fleet. Will not only fuel cell car demonstration runs, there will be supported by the United Nations in the global tender to fuel buses in the street.
