Often go out to the people, and each trip will find luggage in a large part of the weight of the charger, such as computers, cameras, mobile phones, shavers, MP3, but also often forget to bring a charger tortured . Imagine, if unified charger, airports, hotels and other public places are free to charge, how much trouble can be omitted.
Of course, the benefits of unified charger is convenient.
With the popularity of mobile phones and other electronic products, the e-waste problem caused increasing cause for concern. The charger is often sold together as product attachments. The old charger number of people continue to update these electronic products accumulated huge but useless. Manufacturing and transportation of these chargers not only increase the cost of consuming resources, pollution of the environment at the same time.
More about the charger is not unified caused by energy consumption and pollution, environmentalists and experts have suggested.
For example, under the pressure of environmental protection, manufacturers introduced the charger energy than systems, aims to promote people to use and lower energy consumption charger; experts continue to study how to develop a more efficient battery and charger details charger cooperate in order to achieve maximum service life of the battery, and battery in hopes of reducing environmental hazards; scientists want to design a wireless charger coupling technology to solve the charger and battery aging; Global Institute of Electrical and Electronics Engineers, Inc. also launched an initiative, I hope design a smart charger, the charger can identify different types of batteries (such as lead-acid batteries, nickel cadmium batteries, nickel metal hydride batteries, lithium-ion batteries) and take the most optimal way to charge it. The U.S. Department of Energy and the Global Institute of Electrical and Electronics Engineers Association also co-financed this project.
Calls for unified charger, then, why the delay can not be unified?
In June 2009, the European Commission said, the world's leading mobile phone manufacturers have agreed to a unified European mobile phone charger charger in Europe, starting in 2010, will be a unified standard. EU set an example, but the specific implementation of the results remains to be seen.
Earlier this year, the in Spain 2009 Mobile World Fair, the GSM Association and 17 mobile operators and manufacturers announced plans to Micro-Usb adopted as the universal charging interface. In accordance with the objectives of the Agreement, since January 1, 2012 onwards, all new mobile phone models listed, will support a universal charging connector, and a new charger to 50% energy saving.
We still can not predict The standard three years after the implementation of how exactly how many manufacturers will participate in the new charger price, how to deal with a huge number of old charger. In addition, even if the phone charger really achieve reunification, when other electronic products charger unified to achieve? The road seems very long.
A recent study of the Xiamen University, China Energy Economic Research Center, discussed the unified charger difficulty. First, the problem of vested interests. SAN said, Nokia phone sales and service margin remained at 19% to 20% to nearly three years. Difficult unified primary reason is that a huge vested interests, the manufacturer has been formed on the charger.
Second, from the technical reasons. Different manufacturers have different technical input on the battery and charger. If unified, investment and income division? Phone (including battery) progress, such as thinner and lighter, has unified charger can adapt to changes in the cell phone and battery?
The third reason comes from the division of responsibility for the accident.Existing phone Disclaimer generally have this reminder: If you are using non-branded original chargers such as leakage, explosion and loss caused due to the charge, the manufacturer shall not be responsible for.Charger uniform, even with complete safety and other standards, but if something goes wrong, who will be responsible?
However, in addition to the interests of the more difficult problems, other technical issues should be resolved. The presence of external technological progress as well as product liability division. The solution of these problems often requires greater investment is also needed in policy guidance as well as on the institutional and legal to make better arrangements.
