With the development of science and technology, the more and more people love the science and technology products around them, and the functions are more and more abundant. However, in order to achieve rich functionality, the battery life requirements are also getting higher and higher. Therefore, there are a lot of mobile power products with large capacity and long life on the market. However, the quality of these mobile power products is uneven, and it is easy to buy unsafe products for unfamiliar buyers.
Many people think there is no match in the field of mobile power standards, but in fact, in May 1, 2014, China Chemical and Physical Power Industry Association released the industry standard --- USB interface class mobile power. And manufacturers participating in conferences and standards development will test and certify the mobile power source manufactured in 2014.09.01 according to the industry standard. We all know the background, then I will focus on this standard to do a few key projects under analysis, please enlighten.
The first point, we all know that mobile power capacity identification problem. Currently on the market of mobile power standard capacity is basically the capacity of batteries, such as 10000mAH. Industry standards at this point made two provisions above to circumvent this nominal. 1) Rated energy, the subject of the energy is the cell, that is 3.7V * cell capacity, such as 3.7 * 2000mAH. Is the description of the batteries, considering the above UN38.3 international standards. 2) rated capacity, this is a more controversial items. Concept, the effective discharge capacity of mobile power, in mAH or AH. The key point is effective discharge. Effective discharge refers to the output voltage between 4.75V-5.25V, if the discharge voltage during the entire load is lower than this value, the judge failed. The effective discharge capacity will be marked on the mobile power body. In the future are 10000mAH mobile power, look at the output capacity (rated capacity), we can compare the more efficient, it will guide consumers, this is the industry standard.
The second point, about batteries. We all know that mobile power occasional news, what is the use of an explosion ah, burning in the subway caused a stir ah like stuff. Industry standards have also made efforts in this regard, which provides mobile power batteries must comply with GB / T18287-2013 --- Lithium-ion battery pack for mobile phones General Specifications. This will, to a certain extent, ensure the reliability of the batteries and also ensure the safety of consumers.
The third point about security. Mentioned earlier, the safety of the batteries, and now about the safety of the circuit board. Standards require mobile power at least have the following protection ---- short circuit protection, overcharge protection, over discharge protection, discharge overcurrent protection. With the above protection, but also to a certain extent, to ensure that the use of mobile power security.
The fourth point, on the shell. The standard also specifies the use of mobile power shell fire rating, so to some extent, to avoid the shell burning, resulting in greater security risks. Shell fire performance should be consistent with the provisions of GB4943.1-2001 188.8.131.52, to V-1 standard.
In addition to the above four points, the standard also on the mechanical properties of the mobile power supply, accessories line swing performance and input and output port salt spray test and so on. In short, the emergence of industry standards is to a certain extent, to help consumers buy safe, reliable, the heart of the mobile power.
Recently, the issue of mobile power security has become the focus of attention, in fact, the time of purchase, the price is not only the only consideration, quality and safety is the most important, hope that after reading this article, we can gain something.
