Chroma and Altair to Develop Digital Twins for EV Propulsion Testing Systems

July 15, 2019 by Paul Shepard

Chroma ATE has signed a strategic cooperation memorandum with Altair Engineering (ALTR) 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 a seamless vehicle engineering and validation process.

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.
