Lithium-ion Laptop battery safety
Standards should be appropriate means to seek and establish product safety and performance of the best combination, if it is not simply focus on safety, of course, the more stringent requirements as possible, but the overall technical level of the product restrictions, the better the security often means more poor electrical performance levels canon eos 350d vertical-grip.
Lithium-ion battery performance level is the most advanced and fastest growing commercial chemical power, and become mobile phones, laptop computers, digital cameras and other high-end portable consumer electronics products matching the power of choice. But its structure and principles of weakness, frequent occurrence in recent years, lithium-ion battery explosion wounding or recall of products due to security risks and other incidents, lithium-ion canon eos 400d vertical-grip safety has become a hot topic in national life, with the attendant safety standards for lithium-ion battery and related work has also become the focus of attention of various parties.
China Li-ion batteries to be coordination between the various standards
Current domestic and international basic safety standards for lithium-ion batteries are in line with detection-based standard, that standard provides short-circuit, over canon eos 450d vertical-grip charge, over discharge, vibration, shock, extrusion, impact (drop), hot-box, low atmospheric pressure, temperature cycling and other electrical , mechanical and environmental aspects of the pilot project, to simulate the battery in normal use and foreseeable misuse of the time of application, to ensure that products in these cases, security. This standard form has the advantage of clear criteria, operability is good, just for the finished battery to carry out laboratory testing to determine whether you can meet the standards, the disadvantage is that can not be fully effective in protecting the product quality and reliability, because the security of a product performance is an integral aspect of product design and manufacturing processes formed and established, the current standard of evaluation subjects with this biased, in addition to safety tests are destructive tests fujitsu lifebook c2210 battery, can only be conducted using samples taken, this method itself There are also a certain degree of risk probability.
Contrast to the standard can be seen at home and abroad, China’s safety standards for lithium-ion batteries lack of overall planning, basic fragmented. On the one hand between the state and industry standards of 2, as well as a lack of coordination between various industry standards, there is a certain cross-standard objects fujitsu lifebook c2220 battery, repeating the other hand, there is no uniform standard of guiding ideology, both simple safety standards, including the electrical properties have , environmental performance and safety performance applicable to all the demands of the general norms such as the nature of standards. In contrast, the same organization within the system of foreign ideas and standards in the work of inter-relations are more unified, coordinated, such as the IEC for the safety of their products a separate standard-setting, other criteria such as product specification electrical properties of the total, and other requirements, safety requirements direct reference to safety standards; IEEE are developed for different purposes, including security requirements, respectively, including general specifications of products fujitsu lifebook c2230 battery.
