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.

■Safety Evaluation, Lifespan Testing, and Characteristic Evaluation of Battery Units Lithium-ion batteries are composed of flammable materials and inherently carry the risk of smoke and fire. With the rapid proliferation of secondary batteries, fire incidents have been increasing year by year. This is partly due to the insufficient verification of smoke and fire risks. - Not all batteries are subject to PSE (Product Safety Electrical) regulations. - PSE certification tests do not fully verify safety. - Necessary protections may not be included. As a third-party verification of battery units, we assess the battery's capabilities through tests different from PSE testing: - Nail penetration test (simulating internal short circuit to assess capabilities) - Heating limit test (heating to thermal limits to assess capabilities) - 0V charging prohibition protection (assuming recharging after long-term storage) ■Power Supply Unit and AC Adapter Evaluation / Failure Analysis - Safety evaluation of power circuits, wireless power transmission, and USB PD (Power Delivery). - Conducting various noise injection tests to verify noise tolerance and characteristic evaluation in line with power supply specifications. - Evaluation of power supply devices such as power supply units, AC adapters, UPS, and DC-DC converters, including evaluation of the built-in power circuits and verification of power failures.

We undertake the investigation of the causes of smoke, fire, and burn damage in electrical and electronic products.

We accept contracts for reliability evaluations, environmental testing, and safety assessments in accordance with various standards. If any issues arise after implementation, we also conduct cause investigations. Furthermore, based on a standard test, we propose the realization of difficult tests through coordinated control of multiple devices (developing software and test fixtures as needed). ■ Overview Are you giving up on achieving the desired reliability evaluations, environmental tests, and reproducibility tests because conventional testing machines cannot set the desired test conditions or multiple test conditions for reproducing issues? By coordinating control of power supplies, electronic loads, constant temperature chambers, multimeters, bidirectional power supplies, and more, we conduct reliability evaluations, environmental tests, and reproducibility tests tailored to your needs! - We select the necessary equipment for coordinated control based on your requirements and develop a testing plan. - You only need to prepare the test samples. We will prepare other equipment and coordinated control. - We flexibly respond to various sensor integrations and fixture manufacturing as needed. ■ Key Points Even if the evaluation tests you want to conduct cannot be performed with existing testing equipment, it may be possible to realize them by coordinating control with physical wiring switching circuits and various sensors. Please feel free to consult with us.

There are many standard tests that are recommended to verify products for sale. For example: - JIS standards (JIS C 60335-1 Safety of household electrical appliances, etc.) - IEC standards (IEC 61960 Batteries for portable devices, etc.) - UL standards (UL 1642 Lithium batteries, etc.) and so on. We undertake public standards applicable to household and commercial electrical products. ■ Do you have any of these concerns? ■ - I want to conduct standard tests on developed or purchased products, but I do not own testing equipment. - A business partner has requested the implementation of standard tests, but I have no experience. - I cannot determine whether the test results from the supplier are appropriate.

In response to your company's request for "visualization and quantification" of equipment degradation and product lifespan, we will alleviate the invisible concerns. By visualizing and quantifying the degree of degradation and remaining lifespan of equipment currently in operation and use in the field, you can grasp the timing for maintenance and replacement. This is especially important when using products in special environments that differ from the original installation conditions, as more careful analysis is required. Eurofins FQL, with its extensive experience in the fields of electronic device and component reliability evaluation, failure analysis, and analysis, will assist you in solving challenges by combining various measurement and analysis methods.

When power semiconductors and power modules are repeatedly turned ON and OFF, the self-heating and cooling of the components and modules cause distortion due to the differences in expansion of the bonding materials, leading to a deterioration in bonding reliability. We offer power cycle testing that takes into account the heating operation due to repeated self-heating and cooling cycles. ■ Components, units, and devices where the adoption of power semiconductors and power modules is progressing: - Traction inverters for electric vehicles (EVs) and hybrid electric vehicles (HEVs) - On-board chargers and DC-DC converters - Motor control, robots, machine tools, elevators - Industrial inverters and uninterruptible power supplies (UPS) - Solar power generation systems and wind power generation systems

We would like to introduce environmental testing equipment used for reliability evaluation and environmental testing of not only electronic components and devices but also industrial products and consumer goods materials. Upon consultation, we can place your samples into the testing equipment under specified conditions and provide you with the data and samples after the tests are completed. If you wish to entrust testing to an evaluation organization, do not own testing tanks, or are temporarily unable to use them, please check the equipment specifications when considering outsourcing reliability evaluation tests. *The catalog of equipment specifications listed is only a portion of what we own. For further details, please check our company website.

The usage environment of electronic devices varies. The impact of corrosion caused by various environmental factors tends to increase. Corrosive substances generated from hot springs, volcanoes, waste, and rivers can lead to corrosion of electronic components, printed circuit board wiring, connector contacts, and switch contacts in electrical equipment, potentially causing serious troubles. Therefore, investigating corrosive substances in the usage environment is effective for equipment maintenance and ensuring the reliability and lifespan of electronic devices. Our original corrosion environment diagnostic kit, "Eco Checker II," offers a low-cost and simple diagnostic procedure. It allows for easy investigations such as screening for corrosive substances through multi-point surveys. ■ Free Webinar Announcement! ■ We will introduce methods for diagnosing corrosion environments centered around our original corrosion environment diagnostic kit, Eco Checker II. 【Date】 July 22, 2025, 10:00–10:30 【Venue】 Online (Teams) This is recommended for those who are concerned that atmospheric conditions in the operating environment may lead to electronic device failures, or who wish to reduce failure risks in harsh environments such as hot springs or wastewater treatment plants.
