Unified mobile phone charger is neither fish nor fowl, or benefits the nation?
Now, who?s home cell phone few scrapped, others would feel very strange. Xiao Bian I use the phone?s time is not long, a total had not changed Guoji Bu mobile phone, home charger, but there are five more, that does not include had to give as gifts two Nokia Universal line charge. It is reported that as of October 2006, China?s nearly 450 million mobile phone users on average about every three individuals have a cell phone. As mobile phones become increasingly customized design, cell phone replacement faster. Manufacturers to introduce new products are essentially homogeneous line charge Charger in place, buy a new phone if there is standard in the case, and then attached charger models will greatly enhance the customer desire to purchase. Because the pursuit of fashion and mobile phones stolen and other reasons, as a direct result of China?s current annual replacement of more than 100 million mobile phones in the objective reality, such a high frequency of cell phone replacement will be idle mobile phone charger is even more prominent.
Recently, a friend to use leisure time he opened a Shop, specializing in selling various brands of mobile phones. In chatting with him learned the buyer of the product inquiry, the charger is their style is an important aspect to consider. I jokingly said to him, you can tell the buyer, in the near future , the domestic mobile phone charger will be a unified standard interface, you buy a new phone, no need to consider any charger problem. Friends hear, with immense interest, the moment surfing the relevant information, as well as Ministry of Information Industry released the standard expressed great affirmation and support. I believe a friend of this performance represents a large number of consumer attitude towards the matter. If implemented, consumers can no longer be piles of chargers at home and worry about meals when they will not be forgot his charger can not charge their cell phones and anxiety. Moreover, the acquisition of new mobile phones, we also do not have to buy a charger, not only reduces the cost of the purchase of mobile phones also reduces e-waste pollution, can be described as ?nothing like? It?s really great benefits the country and good!
But the contrast of, Xiaobian understand that ?mobile phone charger and interface, the technical requirements and test methods the industry standard? requires that all mobile phone charger uniform interface, but does not require cell phone charging jack are also unified. This means that different phones can share the charger though, but it can not share the power cord, each phone must also bring their own can only be plugged into their own cell phone interface, power cord. Moreover, the standard is only recommended standards are not mandatory. Such as Nokia, Motorola, Samsung and other major manufacturers are already using a global standard, most likely no longer willing to specialize in the production standards of Chinese products, so for this standard may be somewhat inconsistent or reaction frigid. These large international companies, but it is China?s mobile phone sales of big, in the minds of consumers have a firm influence. Therefore, this non-mandatory standards, which means the manufacturers can choose not to adopt this standard, the international big because of the above reasons, the possibility of using this standard is the smaller and small. If you have more than 50% as a share of the mobile phone market with sales of large do not, then the significance of the development of this standard will be greatly reduced. Therefore, the public long-awaited unified charger standard ?neither fish nor fowl? It?s somewhat disappointed.
Mobile phone charger interface standard uniform too ?ambiguous?
Ministry of Information Industry issued the ?mobile phones and chargers and interface technical requirements and test methods? to inform the communications industry-standard, this standard in consumers, the media have attracted a great deal within the scope of the response, claimed responsibility for the environmental protection, consumer rights , the situation of domestic mobile phones have played a very good role.
It is reported that foreign mobile phone makers for the implementation of this standard holds the conflicting emotions, in order to understand that domestic mobile phone makers is how to treat the implementation of the standard mobile phone charger, the author interviewed several domestic handset makers relevant responsible person, in the chat with them to the standard of the time when the impact of domestic mobile phones, and nearly all found the same problem they did not understand the mobile phone charger and interface of what is meant by specific criteria.
Generally agreed that mobile phone charger and interface harmonization of standards should be primarily refers to the connecting cable and mobile phone charger interface, unity. The reporter obtained Posts & Telecom Press release, ?The People?s Republic of China telecommunications industry standard? ? ?Mobile Communications Handset Charger and Interface Technology Requirements and test methods,? a book, according to the text in the introduction, this charger handset involved The interface with the charger located in the charger side of the plug from the socket and the mechanical and electrical properties to meet the definition; charger through the connecting cable to connect the other end with the handset to achieve charging. Handset and connection cable interface designed by the designer.
Such a standard, not only allows the consumer disappointment, and even the handset manufacturers are surprised stakeholders, a relevant person in charge of domestic manufacturers believe that such a standard uniform is really no practical significance. Consumers also identified a wide range of mobile terminal to connect a unified interface, so that did not carry the charger when the charger can be found everywhere for their own charge the phone. And, when purchasing a new phone, but also do not have to choose a battery charger at home, several mobile phones can share a single charger.
By today?s standards, but spent part of the charger plug, cable components, notably the mobile phone interface, not unified, so for each phone had to accompanied by the data lines. Now do the standard uniform, so why not bring unity to do it more thoroughly? Consumers think that the use of the charger is not humane reason is that almost every brand mobile phones and even the same brand of different models of mobile phone chargers are different, each phone can be made between General Motors, people are generally forgotten charger when the battery charger in order to realize the benefits of a unified standard, can be used casually by one. It now appears that the unity of the existing standard does not solve these problems, you still can not forget the Okanagan-line charging anywhere convenient. Therefore, this standard can be seen that there are still inadequacies, the relevant departments in the formulation of a standard time should not be ?behind closed doors?, but to a wide range of solicited the views of consumers and related businesses, gather knowledge point of view to develop suitable applications, to meet the needs standard.
Also you can see a problem, although this standard is not a national mandatory standards, there is no mandatory implementation of this standard on the impact of mobile phone manufacturers and consumers is still great, but why we do not know the specific content of the standard conditions, resulting in so many misunderstanding? Can be seen that the relevant departments have not done enough publicity for a country?s industry standards, provide benefits to industries and enterprises deeply failed to understand, but also to promote what? Therefore, the development of a standard, one should seek the view of companies, allow enterprises to participate in standard-setting work, the implementation of this standard is also very beneficial. Second, since it is the policy in order to benefit the people, for China, a great and proud country, the standard should be enforced, that is able to achieve good results immediately in a standard can command the right to speak, why not!
The future development of the battery
In mobile technology, we always never-ending technological advances as a birthright. For notebook computers, music players, handheld computers (PDA) and mobile phones, the constant ?downsizing? is a must, at the same time, but also add features to enhance speed, extended memory. However, there is one thing dragged on for legs ? that is the battery.
Recently, the high incidence of notebook computers fire accidents, so that the battery has aroused great concern of all parties. Incident was Sony Corporation (Sony, hereinafter referred to as Sony) in the production process problems caused by more than 600 million batteries were recalled. When the incident became clear, people still need to face the undeniable fact ? the battery power issue is still firmly tied us, the digital operation or the capacity of the game and thus be greatly limited. Even more unfortunately , in recent years this situation has not changed much. Battery power, compared with the needs of users, but also far apart, and the lack of a major breakthrough ? despite the battery capacity of these devices than ever before have some improvement.
Mobile device battery is a need to overcome the technical fields. Therefore, some experts believe that, consumer electronics, notebook computer and communications industries should be from the existing battery out of the conceptual framework, the use of new alternative technologies to give portable mobile device. Some of their ideas is indeed good to be true. For example, to a mobile phone loaded block hydrogen fuel cells, another example for BlackBerry (BlackBerry) PDA to install a small gas turbine engines. These concepts are ahead, but it had to recharge every few hours to shake off the shackles of conduct like this bold experiment is necessary.
Turbine engine on a chip
Massachusetts Institute of Technology (MIT) researchers are testing, by means of micro-electrical mechanical system in the continuous development of power sector, in the coin-sized silicon chip establishment of micro-gas turbine engine. Continuous supply of such devices compared to the same time, the weight of the battery 10 times longer, so developers created a smaller generators. The micro-processing engine model consists of six silicon wafers bonded together, of which compressor, combustor, rotating turbines and other necessary functional modules have been cured in a separate silicon layer. Fuel and air mixture in a tiny combustion chamber and burned. Micro-turbine blades made of material per second transfer rate of 20000 high-speed rotation.
?We have confirmed that all components can work properly.? Professor in the Department of Aeronautics and Astronautics Massachusetts Institute of Technology Allen ? Epstein (Alan Epstein) said, ?Now the challenge is to make them work together, and that the integration of group together. ?Epstein predicts that this generation model can be displayed within a year. To put into commercial use, however, then it had to spend three or more years time.
Even if the power supply to be perfect, it must cross the barrier in front of the battery replacement technology barriers. If it is the price of the battery so cheap as now, it can achieve an annual output of hundreds of millions of batteries do? People would be willing to surmise in a pocket or purse inside a combustion engine do?
Hydrogen fuel cell is about the birth of another alternative. Arizona State University (Arizona State University) chemist Church ?Jierwaxiao (Don Gervasio) are working on a hydrogen fuel cell, which uses the concentration of 30% of the mixture of borohydride solution to produce than the same volume of solution ? a more advanced hydrogen-rich hydrogen. He explained that such boron hydride solution than conventional fuel cells more stable and more secure.
?We are creating a boron hydride container, on the inside even if lighting a match can also be easily extinguished.?Jierwaxiao said. We can see that he is very concerned about this that any new power supply will be faced with security problems. Solution flowing through the element made of ruthenium catalyst to release hydrogen , and then through a layer of film, with the fuel cells combine oxygen to produce electricity.
This approach must have to overcome some obstacles. In R & D initially, as the reaction produced a by-product can not be dissolved, resulting in oxygen electrolyzer being blocked, research once frustrated. R & D team was the use of ethylene glycol (an antifreeze) to dissolve boron oxide, without affecting the oxygen generation.Jierwaxiao explained that he led the team again to 1 ~ 3 years time can develop a prototype of industrial products, but the commercial product will have to be able to come out a few years.
Other companies also continue to explore an alternative to liquid methanol fuel cells, but there is no where near the success of a development. Because it has to meet three conditions: laptop battery to meet the demand, the volume should be small enough to be able to insert the battery slot small space, while manufacturing costs but also, and now the battery close.
Limited choice
Lithium-ion batteries since the 90 years since the last century, replaced nickel-metal hydride batteries, the late 90s and gradually notebook computers and handheld devices become the mainstream configurations. Mainly because in the same size, the lithium-ion can store more power, but also far more portable than the nickel-metal hydride materials. Over the past few years, lithium-ion technology in energy density has increased by 20% ~ 30%. According to the Portable Rechargeable Battery Association (Portable Rechargeable Battery Association) data, are now common in general to achieve the laptop battery power supply 4 to 5 hours, while in 2004 only to maintain 3 hours. Currently the world?s lithium-ion batteries produced each year there are about 2 billion.
Most lithium-ion batteries are based on cobalt oxide inside the very basis of the negative. Because it contains oxygen in the material, it is extremely unstable. If the production of lithium-ion slightly careless, you may have short-circuit or overheating, and in some occasions, the battery inside the electrolyzer could spark a fire. Most major notebook manufacturers have been recalls of Sony-manufactured batteries, battery replacement product research and development on the news reports continued to hit the newspapers , but also let the little there are concerns that the industry became a focus of media attention.
The good news is, the problem appears confined to the Sony one. The battery industry, most people also believe that the company has the ability, and certainly this important process can solve the problem. Sony said it has taken measures to prevent the problem arises again.
The bad news is, it seems we have to continue to suffer from the status quo of this technology. Frost & Sullivan Inc. analyst Sarah ? Bradford (Sara Bradford) in a recent report claimed that lithium-ion battery energy density has been close to its theoretical limit. While the new alternative to the possibility of the recent market has little in the short term could only expect a slight improvement. ?In the future two or three years and did not really much has changed.? Intel Corporation (Intel, hereinafter referred to as Intel?s) senior vice president and general manager of Mobile Business Unit Pu David (David Perlmutter), said, ?Now the industry is focused mainly on the , how to improve the conventional lithium-ion battery manufacturing process and improve the reliability of the battery. ?
But there are many start-up companies and academic research institutions, is conducting a relentless effort to make plans for the portable power supply projects, building blocks. (Sony declined to discuss it has already carried out in the next generation of battery R & D work.) Battery(, Digital Camera Battery, ) testing and development of alternative technologies is accelerating among the many groups are actively seeking funding, find partners and mining-related clients.
To extend battery life
Perlmutter said that since no new technology to change the game, Intel engineers and researchers had to ?1 mW 1 mW,? looking for the system to reduce electricity demand components. Perlmutter is estimated that savings from the system they are part of, you can extend the battery life of 25 ~ 30 minutes.
Another alternative approach to lithium-ion batteries is to reduce its volatile chemicals, but this would result in shorter battery life. Notebook manufacturers already keenly aware that consumers prefer a longer battery life time, and not very concerned about a relatively little battery-burning incident occurred.
?No one (notebook suppliers) are willing to act as a leader, to the customer than the competitor?s product with a shorter battery life,? Vaillant Technology, Inc. (Valence Technology, hereinafter referred to as Vaillant Technology) is responsible for global sales and marketing operation Dean ? Boggs (Dean Bogues), said, ?The problem is the new technology will certainly be safe enough? If this is an easy solution to the problem, then why over the past 10 years, no one has to notice it?? Viagra , , to science and technology is a battery-replacement technology suppliers Laptop AC Adapter.
Chemicals is very important
Vaillant technology manufacturing and marketing of a lithium-ion batteries used in non-volatile phosphate-based cathode product, brand name called Saphion. Vaillant technology claim that it can significantly reduce the possibility of fire. But it has a very big disadvantage: Vaillant technology product requirements must be at 3.2 volts, the existing 3.6-volt battery for electronic equipment have to re-design or refurbishment can only be used in conjunction.
To make matters worse, although Viagra can be potentially effective life of the battery is a traditional lithium-ion batteries 3 times, but the use of time was reduced by 40% than the latter. The conventional cobalt oxide-based lithium-ion batteries may have 4 hours of usage time, while the equivalent of Viagra to the battery is only 2.5 hours of usage time.
Now, Vaillant Saphion technology providers based on science and technology, a , , battery accessories, can be plugged into a laptop computer, the use of time extended to 10 hours, for those who are willing to carry the additional electronic equipment to provide electricity for long distance travelers. This is known as N-Charge power system weighs about 3 pounds, is currently in a power outlet fewer classrooms, with wireless mobile nursing stations are used in hospitals.
Boggs said that Vaillant Science and Technology are working on next-generation Saphion II technology, research and development to enable it to 3.6 volts in the working environment can replace laptop batteries of plug-in, while the use of time than conventional lithium-ion battery is only 10% less 15%. The new product is expected in 2007 will be introduced into the market. ?If we can provide only a 10% less than conventional technology, but absolutely safe alternative products, the market will undergo great changes.? Boggs said.
Another commercially available phosphate-based A123Systems lithium-ion technology is the company?s nano-scale solutions dell notebook battery. DeWalt / Black & Decker Power Tool Company provides a complete set of 36-volt power tools, effective use of the A123Systems battery technology.
The smaller the better
A123Systems CEO (CEO) and Chief Executive David ? viaud (David Vieau) are eager to develop nano-phosphate technology market. Viaud said the company is actively engaged with the investor handset manufacturer Motorola Inc. (Motorola, hereinafter referred to as Motorola) and Qualcomm (Qualcomm, hereinafter referred to as a high-pass) to negotiate. A123Systems is also involved with the hydrogen fuel vehicle-related projects. However, if you want into the notebook computer applications , , , they still have to wait several years.
In addition to bringing a number of advantages for phosphate addition, A123Systems nano-technology also reduces the battery in the single-particle size, its lithium-ion technology, from the traditional average of 1 micron and more reduced to 100 nanometers, or about the original a volume of 1%.
Smaller particles can be faster than the average absorption of lithium batteries, the battery charging speed so quickly. For example, if a lithium-ion batteries with ordinary mobile phone charging time need 2 ~ 3 hours, then using this new type of battery as long as the short span of 5 to 10 minutes can is full, viaud added. Ordinary cell phone battery can be charged 300 ~ 400 times, and A123Systems of technology to increase that figure to 7,000 times.
Battery manufacturers are trying a variety of chemical formulations in order to find an alternative to even more than lithium-ion technology. Zinc Matrix Power Company?s CEO and president Ross ? Dube (Ross Dueber) believes that his company?s alternative to chemical batteries next year can be commercially deployed. Intel is the company?s investors, and in September 2006 Intel Developer Forum (Intel Developer Forum) on the nomination of the company to ?accelerate the technological innovation Award? winner.
Dube said the company?s approach is the use of silver and zinc, lithium-ion offers , , two times the duration of use, and its water-based chemicals that are neither flammable nor toxic. The company was originally focused on military applications, two years ago, was Intel?s investment, then it changed directions of research focused on the development of a use of time can be up to 10 hours of laptop battery.
?Lithium-ion battery 15 years ago had started, when its life span is only half the nickel-metal hydride batteries. But use the time was 30% longer than the latter, so the price is still acceptable to consumers.? Dube added .
Zinc Matrix Power planned with laptop and mobile phone manufacturers to work together in preparation for next year will be a new design into production. Dube revealed that at the early stage of this technology is likely to be classified as ?Road Warrior Notebook ? and other more high-end equipment options.
