The new phone charger standard is in the approval of

Reporter learned from the parties concerned, following our

Mobile Charger is included in the standard YD/T1591

IT U standard, the new phone charger standard YD/T1591 (Second Edition) development has been completed, is in the approval process, the fastest is expected to be granted during the year.

According to Ter laboratory director, said He Guili, and in 2006 issued YD/T1591 (first edition) compared to, YD/T1591 (Second Edition) is a further major mobile phone charger mobile phone side of the interface standardization, proposed three standard interfaces: MiniUSB, MircoUSB and 2mm cylindrical interface; addition further enhanced the

Power supply Adapter's performance and to expand the scope of the standard not only for charging, but also for data transmission interface, not only for cell phones can also be used for other small

Home Appliances And other ICT equipment.

To why use of the three interfaces as a standard interface, Hegui Li said, through research, MiniUSB interface is currently on the market to use interface to form the largest proportion, the industry has a good ability to adapt; MircoUSB Although the low rate , but its small size, high reliability, technological superiority, the trend has gradually replaced MiniUSB; use 2mm cylindrical interface, mainly on account of the standard universal power adapter required, in addition to other mobile phones also can be used in other ICT product of the power supply or charging. Universal mobile phone charger as standard definition of the original intention of not only reducing the duplication of purchase of mobile phone charger, but also for mobile phone chargers and other ICT products, charge / power supply common, other ICT products in order to reduce the number of power adapters. Other ICT products, many not apply to USB interface, and application of 2mm cylindrical interfaces.

He Guili, said: "In the long run, because MircoUSB replace MiniUSB is inevitable, so the future may be a natural transition to the two interfaces: MircoUSB and 2mm cylindrical interface."

"Although the implementation of this standard will affect the interests of some enterprises, but on society and the users but they are good but no harm, and is technically entirely feasible." He Guili said.

Hegui Li said, in 2006, China formally promulgated the cell phone charger standard YD/T1591 (First Edition), due to the specific circumstances at that time, the first edition, only unified charging plug, and the interface between the cable, however, on the cable line and the interface between the mobile phone does not make clear requirements. This has resulted in mobile phone charger mobile phone side interface is still diverse. This was mainly because of the prevailing market conditions are very complex, cell phone charger too messy, difficult standardization step. So when we step on the proposed standardization strategies: the first unified power supply side of the interface, and then unified phone side interface. More buffer to the mobile phone companies to accept new standards. Today, the first edition of two and a half have been implemented, relatively effective, but also to achieve the desired effect. Implementation of the new standard the timing of the second edition have been basically established, the resistance is also much smaller.

According to He Guili description, from the formal implementation of the standard 2007 to now, there are 6,000 varieties of handsets using the standard (YD/T1591 first edition), total more than 400 million. This means that 400 million cell phones currently on the market charger has achieved a degree of interoperability. More importantly, as the standard charger converter power, load voltage, current intrusion and other indicators of the specific requirements,

Energy Reduction of the effect is very obvious.

He Guili said that if the next standard YD/T1591 (Second Edition) implemented for some time, most consumers and families to switch to a generic charger, you can implement, "buy a mobile phone charger did not buy," target According to the present calculation of annual sales of 200 million phones a year can be reduced up to 200 million mobile phone charger. This reduction will not only cost consumers to buy the charger, but also the social costs of dealing with these chargers.
