AI-Driven Expansion of Megawatt-Scale Data Centers Puts Energy Efficiency in Global Spotlight As AI models grow in scale and computing demand keeps rising, the world has entered a new phase
To address the testing needs of next generation charging communication and high power charging architectures, Chroma has introduced the Chroma 8000 EV & EVSE automated test system (ATS), designed specifically for simultaneous multi connector testing of DC EVSE (EV supply equipment), EV charging compatibility validation, and high current liquid cooled charging tests.
In automated testing, C# and Python are among the most widely used programming languages in an engineer’s toolkit. The real challenge, however, lies in turning these tools into stable, industry-compliant
Chroma offers an efficient and comprehensive solution based on the optional AC load capability of the Chroma 61815 Regenerative Grid Simulator (3U/15kVA, high power density). Two key technologies enable realistic, repeatable load simulation: User-Defined Waveforms (UDW) and advanced programming via List Mode.
Chroma’s EVSE Automated Test System (ATS) 8000 is built around in-house developed components, including the software platform, power sources and electronic loads, communication control unit, and other key modules. This supports test requirements for DIN 70122, ISO 15118-4, and ISO 15118-5 communication conformance as well as electrical parameter verification.
As electric vehicle (EV) technology advances, the on-board charger (OBC) has become a core module integrating power electronics and vehicle communications. Because architectures and protocols vary by OEM, test systems face varied and demanding requirements, especially in terms of real-time responsiveness and protocol handling.
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.
At the CharIN Testival North America 2025, Chroma’s EV & EVSE charging test solution stood out among numerous international participants, winning third place in the test equipment category. This event is one of the world’s premier platforms for electric vehicle (EV) charging interoperability testing.
The Chroma 61815, a 3U/15kVA high power density grid simulator, addresses these challenges with versatility. It can function both as an AC source to simulate utility power and, with an optional AC load mode, mimic household appliances or other load characteristics.
