A fire accident frequency? How to make people safe lithium electricity industry

by:Vglory      2020-10-29
Speaking of lithium battery safety problem, the popularity of pure electric vehicles in recent years, has already put the safety of the lithium electricity problem is no longer limited to 'use' the aspects, such as mobile phones, tablet, lithium battery in the 'line' security problem also gradually highlights. 'in' or 'rows' lithium electricity industry bring convenience to consumers the premise and the core of life, is its security. On July 6, causing many low-lying road nanjing night storm water, the water lead to two bubble in water of electric buses to spontaneous combustion fire. Can be seen from the pictures, when the water flooded into the bus wheel half the position of the whole vehicle chassis to soak in the water. According to industry analysis, the cause of the accident is likely to be battery pack water lead to short circuit, in turn, led to a fire. It is understood that international electrician, electronic products are already formulated the related protection grade standard, namely the IP rating ( IP is the abbreviation of IngressProtection) 。 The protection grade is derived from the international electrotechnical commission standard IEC60529, composed of two Numbers, the first number said dustproof and waterproof second number. Waterproof level from 0 8, the greater the number, the higher the degree of protection. The personage inside course of study says, power battery waterproof must reach IP67 rating standards, and it is understood that the nanjing bus fire used batteries, battery pack sealing standard only IP54, namely the waterproof level is only 4. So after a night after soaking, rain comes into contact with the battery, battery caused by the external short circuit, which in turn lead to internal short circuit, cause battery fire. The author thinks that, if the production process, the enterprise have more strict control measures to battery waterproof, to a higher level of waterproof, perhaps the accident could have been prevented. Similarly, on July 10, jiangxi feng LiYe wholly owned subsidiary of shenzhen beauty worship electronic co. , LTD. , aging workshop accident fire explosion, jiangxi feng LiYe also temporarily suspended for the next day. Preliminary exploration, and explosion accident of bums and content for the worship electronic aging workshop of lithium batteries, 4 / f, semi-finished products. It is understood that the worship just to prepare construction nissan 600000 AH lithium-ion polymer battery production line, the battery is for soft package of the fire is still unknown. But because this is not the worship the electronic fire explosion accident for the first time, This year on March 22, the company is a fire accident happened in a warehouse) , so its in the process of production for the safety of li-ion battery fire accident preventive measures are in place is still open to question. The author thinks that, with the development of new energy vehicles industry, lithium ion battery and ordinary people are becoming more and more close, the safety of the lithium electricity problem is becoming more and more aroused people's concern. Lithium electricity enterprises want to seize the opportunities for development, achieve the development of the enterprise, must not sacrifice the 'safe' expense, and in each link attention should be paid to safety issues. After all, safety is the core of the development of an industry can, if even far from safety, an industry and how to develop? Read on: polymer batteries safer than cylindrical batteries? Although the worship electrical fires and explosions remains to be seen whether it is mild package battery, but the Internet 'polymer batteries safer than cylindrical batteries' problem, had an interview with China's chemical and physical power industry association secretary general yan-long liu. Yan-long liu said, two batteries and can't say who is safer than who. The reason is that although the polymer batteries using 18650 batteries is better than soft bag shell steel shell is hard, when the battery internal heated to produce gas, gas is more likely to break through the release of the soft bag shell interface, explosions, seemingly more than cylindrical batteries are less but a gas inside the battery from the electrolyte decomposition form of flammable gas, large accumulation after meet flame will also exploded, damaging not necessarily less damaging than cylindrical batteries explosion. Can see from this, lithium electricity safety there is no fluke, as long as the production, it must be strictly controlled, control the safe hidden trouble again low, to forge a 'safe' confidence in the consumers' mind. Lithium-ion batteries, electric vehicles, lithium battery manufacturer, storage battery manufacturer scooter battery manufacturers, product by the supervision and inspection institute of guangdong province, through international CE certification, by the ping an insurance company of China national group, two years warranty, the first in the New Year.
