Chinese non-laptop battery standard
Recently, lithium batteries because of safety issues, Dell, Apple had to in the global scope of a number of questions on the use of lithium batteries for notebook recall. Currently, the global scale have not yet a unified standard laptop battery, while the Chinese in this regard also there is no specific norms.
Global standard lithium batteries chaos
Globally, the lithium sony laptop battery in a chaotic state standards, national standards, industry-standard parallel tracks. Overall, roughly divided into two systems, one is the national standard
Faction, represented by places, such as JIS (Japan National Institute of Standards), an additional category for the industry, such as IEEE (The United States Institute of Electrical and Electronics Engineers), IEC (International Electrotechnical Commission). Although these two types of standard system on monitoring project at roughly similar, but each has a different emphasis. This case, lithium battery manufacturers in order to enter the world market, had to through a variety of certification.
Agree that the high rate of IEEE1625 standard
At present, the field of lithium battery in laptops, was born in 2004, "IEEE1625" recognition rates are relatively high, the standard is called "The United States Association of Electrical and Electronics Engineers use rechargeable batteries for mobile computers IEEE1625 specification." The specification provides a portable computer battery shape, environmental protection, the battery unit and packaging areas such as minimum standards. According to the norms, effectively prevent from high temperature, impact, vibration and other external causes of the accident. This standard was accepted, another reason is given full consideration to the factors that manufacturers, standard-setting working groups have a number of notebooks, the battery manufacturers, including dell battery , hp battery , IBM battery , Motorola, Panasonic, Sony, Texas Instruments and so on.
Chinese norms blank notebook lithium batteries
Reporter from the National Standardization Management Committee was informed that the standard on lithium sony pcga-bp2r in China also has a number of provisions, such as the original battery standards in Part 4 of the safety requirements of lithium batteries, lithium battery pack hazardous properties of dangerous goods safety inspection norms. But this is only lithium batteries on some of the basic safety requirements, and do not have a breakdown of specific products, laptop lithium batteries toshiba battery with norms is still a blank. Relatively speaking, because of Chinese mobile phone use lithium-ion battery breakthrough in core technology, has produced a "cell phone use lithium-ion batteries total norms" such as national standards.
Battery to build a new standard knowledge of domestic enterprises
Yesterday, according to foreign media reports, Dell, Apple, Lenovo and other electronic circuits and electronics industry association interconnect (IPC) OEM key component members of the Committee has decided, in the middle of next month at the summit held in San Jose, California, developed for laptop and handheld electronic products lithium ion production standards. Electronic equipment standard-setting organizations IPCOEMCCC President JohnGrosso said they will lithium-ion battery design, performance and safety standards to assess, and then work out a unified set of industry standards.
Yesterday, the reporter interviewed separately several major domestic laptop manufacturers, they are the standard of lithium ion that is currently not in the know. Sony Advanced Public Relations Manager, told reporters only from the Internet to see the message, the current has not received any notice. Several major manufacturers have indicated to establish a set of standards, is clearly on the safe use of batteries has an immense amount of good.
Not yet restricted
Portable laptop boarding
Reporter learned from the airlines, at present, domestic airlines to carry the laptop and use does not make any hard and fast rules. Laptop can carry on aircraft, at the same time in the course of flight, passengers can use the power of notebook computers , can also use the plane on the power plug.
Southern journalist told the person concerned, flights on the use of the laptop and there is no brand restrictions. Plug up because of limited flights, passengers are advised to use the best battery power. In addition, United Airlines, Continental Airlines, American Airlines, Northwest, Air France, British Airways, Finnair, etc. that the recent and not for the safe use of laptop initiatives launched.
Expert opinion
Lithium battery have much use of risk?
Dell and Apple recently announced a global recall in laptop batteries, the lithium-ion had aroused public safety concern. Battery Detect famous experts, National 863 Program Director of the Center for battery test Winter Prince in an interview with Xinhua that the safety of lithium batteries are more stable, and consumers do not have too much fear.
Winter Prince said, "lithium batteries with high capacity, energy, and long cycle life, no memory effect, etc., so on the current situation, lithium Fujitsu laptop battery still are achieve security, high capacity and good value for money ideal for battery." experts say that because lithium is a very active and chemical properties of elements at the moment easy to damage by external forces of fire, explosion.
Because the computer is connected to a different system configuration (including the related computer system's security design, different charging system, the different heat dissipation, etc.) the battery will have an impact on security. Therefore, computer manufacturers in the design and production process taking into account the temperature control, the battery has good heat dissipation.
Winter Prince pointed out that consumers buy at the time, it is necessary to know whether the computer has the heat or temperature management system, the attention required to read at the same time the use of electronic product specification for the use of to be aware of the environment. Secondly, to ensure that the computer ventilation, because the computer vent wall, easily induced by the accident. Third, the computer should always be concerned about the temperature and found that temperature anomalies, it is necessary to decisively cut off the power.
