Yearly increasing battery fire incidents. Free distribution of safety evaluation guidebook!
Prevent smoke and fire accidents and short lifespan in advance! We offer safety evaluations for secondary batteries, power supplies, AC adapters, noise tolerance assessments, and characteristic evaluations.
Accidents involving products equipped with lithium-ion batteries, such as mobile batteries, are increasing year by year. There are calls for caution regarding the rise in fire incidents caused by lithium-ion batteries due to high temperatures. Lithium-ion batteries are composed of flammable materials and inherently carry the risk of smoke and fire. As secondary batteries have rapidly proliferated, fire incidents have also been on the rise each year. This is not only due to the harshening of usage environments and mechanisms but also because the risks of smoke and fire have not been fully verified. As a third-party verification of battery units, we assess battery performance through tests different from PSE testing: - Nail penetration test (simulating internal short circuits to assess performance) - Heating limit test (heating to thermal limits to assess performance) - 0V charging prohibition protection (assuming recharging after long-term storage) Do you have any of these concerns? - I recognize that it is dangerous, but I don't know what to do. - I lack experience and know-how in evaluation, and I am anxious about ensuring safety. - I want to determine not only safety but also whether the battery has characteristics suitable for the product. - I want to evaluate the product's durability against high temperatures, drops, and impacts to prevent fire incidents in the market.

Silent change, resurgence. Concerns about the safety and reliability of market-distributed products. How to prevent recalls?
Unstoppable battery fires. Chaos from semiconductor supply shortages. How can we identify poor-quality products and prevent recalls? Poor-quality products are not limited to batteries frequently covered by the media, but also include OEM products, semiconductors that are in short supply, and a wide range of connectors and cables that users prioritize for appearance and price. Suppliers of products need to thoroughly evaluate the components and materials used in their products to ensure quality. However, it is common for manufacturers to change parts and usage without notice, leading to defective products entering the market unnoticed, which can trigger product accidents. Key points to prevent recalls include: - Product evaluation and safety assessment at the time of adoption - Confirmation of supplier quality assurance systems at the time of adoption - Verification of sales through legitimate domestic channels - Regular checks for silent changes Eurofins FQL has been involved in product quality assurance for a long time. Leveraging that expertise, we offer services for safety evaluations of batteries, identification of poor-quality products, and factory audits from the perspective of managing upstream quality.

Caution regarding fire incidents caused by products using lithium-ion batteries. Are the standards tests and safety evaluations for electrical products sufficient?
Products that use lithium-ion batteries and are worn or carried in daily life. It is important to conduct thorough evaluations during the product design phase, rather than relying solely on consumers' charging conditions, impacts, and disposal methods for safety. Eurofins FQL offers services including fire analysis of wireless earphones, smartwatches, portable fans, and mobile batteries (note that analysis may not be possible for severely damaged items), battery safety evaluations, and safety assessments of battery-powered devices such as home appliances (including circuit verification) and analysis services. We are here to help ensure thorough evaluations of products to prevent accidents before they occur. Please feel free to consult with us.
