Chroma ATE signed a strategic cooperation memorandum with Altair Engineering. Chroma and Altair will work together to jointly develop tools for electric vehicle (EV) development and testing, as well as digital twins of e-Propulsion Testing Systems. This effort will involve the integration of model-based development simulation methodologies with Power Hardware-in-the-Loop (PHIL) testing to achieve the performance requirements of e-propulsion systems. The integration of the computational and the physical models will enable what is intended to be a seamless vehicle engineering and validation process, according to the companies.

Chroma advances digital twin system technology in the field of electric vehicle testing, providing a more realistic test solution for high-voltage power components and motor control. The solution will incorporate Altair's simulation and machine learning technologies with Chroma's power supply, loading management and battery charge/discharge system, high-voltage/high-power simulation output to achieve dynamic real-time simulation.

The integrated solution will be able to simulate system abnormal state, failure mode analysis, etc., to reduce product development risks and improve test efficiency. This memorandum allows Chroma and Altair to leverage each other's expertise and technologies to offer robust digital twin solutions addressing the complex design and certification challenges of the electric vehicle industry, according to the companies.

“This synergy with Altair will bring Chroma's electric vehicle power level testing solution into a new automotive application frontier, and accelerate the equipment deployment and business expansion opportunities in the rapid growing EV market,” says Leo Huang, Chroma's chairman & CEO.

Chroma ATE Inc. is a supplier of precision test and measurement instrumentation, automated test systems, intelligent manufacturing systems, and test & automation turnkey solutions marketed globally. Chroma has branch offices in Europe, the United States, Japan, Korea, China, and Southeast Asia.
