Product Focus: LED Power Driver Automated Test System

The Chroma 8491 Automated Test System is equipped with optimized standard test items for LED driver testing (lighting & TV backlight). The user is only required to define the test conditions and specifications for the standard test items to perform the test.

The optimized test items cover 6 types of power supply test requirements. “Output Performances” verifies the output characteristics of the UUT. “Input Characteristics” check the UUT input parameters. “Regulations” test the stability of UUT under varying line-in and loading changes. “Timing & Transient” test the timing and transient states during protection. “Protection Tests” trigger and test the protection circuit, the “Special Tests” provide means to test the most sophisticated UUT’s when unique test routines are needed.

High-Precision Three-Electrode Analysis: Solving Lithium Plating Risks in Li-ion Batteries During Fast Charging to Establish a New Safety Standard for Automotive Batteries

As electric vehicle technology advances into the fast charging era, lithium-ion batteries face increasingly severe challenges regarding safety and lifespan under high-rate charging. One of the most critical concerns is the phenomenon of lithium plating—when the charging current is too high or the temperature is too low, lithium-ions fails to intercalate effectively into the anode and instead deposit as metallic lithium on the surface of the graphite.
