Hitting a Moving Target- Designing a HILS Test Rig for EV Company

April 7, 2022
An EV company needed to design a Hardware-in-the-Loop Simulation (HILS) test system. The challenge: create a flexible and scalable software test system for battery ECUs requiring HILS and a benchtop tester, for a dangerous testing environment.

ECUs are at the heart of many products. During development, HILS is employed to test the ECU in a simulated real-world environment. Instrumentation is used to simulate an ECU’s sensor inputs and capture and verify the ECU control outputs. Faults are introduced, and the ECU’s response is analyzed to check that it is performing in a predictable, safe manner. Learn how automated fault insertion systems allow verification tests to be run efficiently in a controlled and repeatable way.
