Safety evaluation, lifespan testing, and performance evaluation (battery / AC adapter / power supply)

We want to prevent smoke and fire accidents and short lifespan! We offer safety evaluation of batteries, safety evaluation testing of power supplies and AC adapters, noise tolerance evaluation, and characteristic evaluation.

■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.
