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

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.

New Software Platform Boosts Multi-Coupler EVSE Test Efficiency by 40%

Chroma’s New Software Platform Boosts Multi-Coupler EVSE Test Efficiency by 40%

Chroma’s compatibility and functional testing systems for EVSE have already been adopted by a great variety of domestic and foreign testing labs. Many EVSE manufacturers also use our solutions for end-of-line testing in their factories. Besides testing the charging process and safety mechanisms, one of the most important test items for multi-coupler EVSE products is power sharing (load management) testing.

Chroma Unveils Game-Changing Bidirectional DC Power Supplies for Battery Testing and Simulation

Chroma Unveils Game-Changing Bidirectional DC Power Supplies for Battery Testing and Simulation

62000D models offer power ratings of 6kW, 12kW, 18kW, 36kW, and 45kW with parallel and series operation capabilities and voltage ranges spanning from 0 to 100V/600V/1200V/1800V. With its four times auto-ranging operation range, the 62000D can cover a wide range of low voltage/high current and high voltage/low current scenarios for devices under test. This consolidation of multiple DC power supplies into a single 62000D unit brings space and cost savings when integrated into standard ATE systems or laboratories.
