As electric vehicle powertrains evolve toward higher power density, higher speeds and greater integration, e-axle systems operating on 800V platforms at over 30,000rpm face increasingly complex interactions among inverters, power modules, motors and batteries, making system validation more challenging.

The Chroma 1210 and 1220 systems enable laboratory simulation of full vehicle operating conditions by combining high-precision dynamometers with Power-HIL integration. As the company will explain to expo visitors, the platform supports control strategy validation, dynamic load simulation and multi-scenario performance testing for electric drive systems. It further integrates a wide range of real-time vehicle models – such as full vehicle dynamics, driver behavior and road load – elevating testing from the component level to full vehicle-level dynamic validation.

In addition, the platform offers NVH analysis, thermal management testing and seamless integration with high/low-temperature environmental chambers. This enables powertrain systems to be evaluated under extreme temperature, humidity and environmental stress conditions, while also supporting international driving cycles such as NEDC, WLTP and FTP-75 for thorough dynamic performance verification.

Through this virtual-physical integrated testing framework, development teams can validate designs earlier, accelerate software and hardware co-development, and significantly shorten EV powertrain development cycles while improving reliability and performance for next-generation electric propulsion systems.
