The new phone charger standard YD/T1591 (second edition) has been finalized, and are in the approval process,Laptop Battery the fastest this year is expected to be granted. The new version of the Samsung, LG and other manufacturers will have a significant impact.
Further to our phone charger standard YD/T1591 been incorporated into the ITU standard, the standard has progressed. "Currently, the new phone charger standard YD/T1591 (Second Edition) development work has been completed, is in the approval process, the fastest this year is expected to be granted." CTTL master any of Gui Li recently accept the "Communications Weekly" ( net) reporters said.
Coexistence of three kinds of interface
According to Ho Gui Li introduced in IBM Laptop Battery 2006 enacted YD/T1591 (first edition) compared, YD/T1591 (Second Edition) is primarily to further right side of mobile phone charger mobile phone interface standardization, proposed three kinds of standard interfaces, " including MiniUSB, MircoUSB and 2mm cylindrical interface; In addition to further improve the performance of the power adapter, and to expand the scope of application of the standard, not only for charging, also applies to data transfer interface, not only for mobile phones, can also be used for other small-scale household appliances and other ICT equipment. "
As for why use three kinds of interfaces as a standard interface, Ho Gui Li explained: first, through research, MiniUSB interface is currently on the market ThinkPad T60 to use interface to form the largest proportion, the industry has good adaptability. Secondly, MircoUSB although with low occupancy rates, but its small size, high reliability, technical superiority, has gradually replaced MiniUSB trend. Third, the choice of 2mm cylindrical interface is mainly on account of the standard universal power adapter required, in addition to other mobile phones can also be used for other ICT products are widely used in the power supply or charging. Because the definition of a standard mobile phone universal charger mobile phone charger mind not only include reducing the duplication of purchase, but also allow mobile phone charger and other ICT products, charge / power supply General Motors, the other 40Y6797 ICT products in order to reduce the number of power adapters. Other ICT products, there are many not apply to USB interface, while the application of 2mm cylindrical interface.
"In the long run, because MircoUSB replace MiniUSB is inevitable, so the future may be a natural transition to the two kinds of interfaces: MircoUSB and 2mm cylindrical interface." Ho Gui Li said.
Reporter survey, a greater impact by this standard cell phone brands will be primarily Japan and Korea brands. Because most of the other mobile phone brands have already adopted these three interfaces, only the Samsung, LG, Sony Ericsson and other handset manufacturers are still using their original PIN-wire interface.
"Although the implementation of this standard will affect the interests of some enterprises, but for society, to the user but they are good but no harm, but is also ThinkPad R60 technically entirely feasible." Ho Gui Li said.
The time has come to upgrade to the
In 2006, China formally promulgated the standard mobile phone charger YD/T1591 (first edition), due to the specific circumstances of that time, the first edition of only unified charging plug, as well as the interface between the cable, but cable and the mobile phone there was no clear interface between the requirements. This has resulted in mobile phone charger mobile phone side interface is still diverse.
"This is mainly due to the prevailing market conditions are very complex, mobile phone charger is too messy, standardization is difficult in one step. That is why we proposed a standardized step by step strategy: first, a unified interface, power supply side, and then a unified interface,40Y6799 mobile phone side. To the mobile phone business for more buffer time to accept the new standards. "Ho Gui Li said," Today, the first edition have been implemented for two years and a half, the effect is more obvious and also reached the expected results. implementation of the timing of the second edition of the new standards has basically matured, the resistance is also a small a lot. "
According to Ho Gui Li introduced, from the formal implementation of the standard in 2007 to the present, there are 6,000 varieties of handsets using the standard (YD/T1591 first edition), total more than 400 million. This means that currently on the market 400 million mobile phone charger has achieved a certain degree of interoperability. More importantly, as the standard charger converter power, load voltage, current intrusion and other indicators set forth explicit requirements, their emissions-reduction effect is very obvious.
"As a rough estimate: the new standard in the energy conversion efficiency than the non-compliers to upgrade about 10% to 20% a year saving up to FRU 92P1139 500 million degrees." Ho Gui Li said, "the new standard in no-load power consumption on the basis of the original standards has doubled, according to half of the phenomenon of use of mobile phones during a no-load calculation, alone, it is estimated electricity savings of 200 million a year degrees. "
"If the next standard YD/T1591 (Second Edition) implemented for some time, the majority of consumers and families have to switch to a generic charger, you can implement the 'do not buy buy a cell phone charger' goal, according to the current annual 200 million mobile phones sales in the calculation, one year can be reduced up to 200 million mobile phone charger. "Ho Gui Li said," This reduction will not be merely the cost of consumers to buy Chargers, but also the social costs of dealing with these FRU 92P1141 chargers. "
