Digital twins being developed for EV propulsion test systems

July 17, 2019 //By Nick Flaherty
Digital twins developed for electric vehicle propulsion testing systems. Leo Huang, Chairman & CEO of Chroma (L) and Brett Chouinard, President & COO of Altair (R) signed the strategic cooperation MOU on July 16th, 2019.
Chroma ATE in Taiwan is working with Altair Engineering (Troy, MI) to jointly develop tools for electric vehicle (EV) development and testing, including a digital twin of e-Propulsion Testing Systems.

The strategic cooperation memorandum involves the integration of model-based development simulation methodologies, including a digital twin in the cloud, 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 provides a more realistic test solution for high-voltage power components and motor control by incorporating 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 digital twin will be able to simulate system abnormal state, failure mode analysis, and so on to reduce product development risks and improve test efficiency. With the rapid growth of electric vehicles, vehicle manufacturers and component manufacturers will face increasingly more demanding testing standards and requirements.

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.

"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," said Leo Huang, Chroma's Chairman & CEO.
