With the development of technology and technology, people around technology products more love more and more and more feature rich. But in order to achieve the wealth of features, battery life requirements are also increasing. It appeared on the market a lot of high-capacity long battery life of mobile power products, but the quality of these mobile power products varies, for buyers who are not familiar with unsafe products readily available.
Many people think that what does not exist in the field of mobile power matching criteria, but in fact, in 2014 the May 1, China’s chemical and physical power industry association released the industry standard — USB interface class mobile power. And manufacturers to participate in conferences and standards in the production of mobile power 2014.09.01 will be tested in accordance with industry standards and certification. We know the background, then I for this standard of several key projects to do the next resolution, also please advise.
First, we all know mobile power capacity to identify the problem. Currently on the market are basically mobile power capacity targets capacity batteries, such 10000mAH. The industry standard at this point to do the above two provisions to circumvent the nominal. 1) Rated power, this is the subject of energy batteries, ie 3.7V * Capacity batteries, such as 3.7 * 2000mAH. Is the description of core electrical, consider the above UN38.3 and international standards. 2) rated capacity, this is more controversial items. Effective discharge capacity concept, mobile power units mAH or AH. The key point lies in the effective discharge. Effective discharge refers to the output voltage is between 4.75V-5.25V, if the output of the entire discharge process with load voltage drops below this value, it is judged unqualified. Effective discharge capacity identified in the mobile power body. Future are 10000mAH mobile power, look at the output capacity (rated capacity) we can compare the efficiency higher, it will guide consumers, this is the industry standard purposes.
Second, with regard to batteries. We all know that mobile power occasional news, an explosion in the use of what appeared ah, ah subway commotion caused stuff like burning. Industry standards in this respect also made efforts, its provisions mobile power batteries used must comply with GB / T18287-2013 — mobile phone with a lithium-ion battery pack Generic specification. So we can guarantee a certain degree in the above batteries reliability, but also to ensure the safety of consumers.
Third, with regard to security. Aforementioned batteries safety, now under mention about the safety of the circuit board. Mobile power standards at least as protective —- short circuit protection, over charge protection, over-discharge protection, overcurrent discharge. With more protection, but also to ensure the safe use of mobile power above a certain level.
Fourth, with regard to housing. Standard also specifies the use of mobile power shell fire rating, so to avoid burning shell to a certain extent, resulting in greater security risk. Fire performance enclosure shall comply with the provisions GB4943.1-2001 of 22.214.171.124, to V-1 standard.
In addition to the above four points, the standard also for the mechanical properties of mobile power accessories line swing performance and input and output ports of the salt spray test, and so on. In short, the emergence of industry standards, is able to help consumers get safe, reliable power supply side of the heart of the movement to some extent.
Recently, the security problem of mobile power become the focus of attention, in fact, at the time of purchase, the price is not the only consideration, quality and safety is the most important, hope that after reading this article, too, we can be harvested.
