Think your current testing strategies can keep pace with today's electric vehicles? Think again. As EV systems become more complex, outdated testing techniques lead to delays, errors, and failures in the field. Testing strategies must advance alongside EV innovation. That means moving beyond one-size-fits-all fixed testers to tailored testing approaches for mission-critical systems, including powertrain, battery management, sensor and management, and in-car network and communication systems.
Evolving EV testing requires an experienced collaborator who can provide strategic guidance specific to your components and development stage. A knowledgeable partner understands the nuances of core system testing and the necessary methodologies for comprehensive validation. Collaborating with an expert early in the design process keeps your EV testing on pace with advancing technology.

ECUs and other controllers integral to electric propulsion powertrain systems are crucial to safe and efficient vehicle operation. Comprehensive sensor and power switching emulation and HIL simulation give design engineers the data they need. With the right data, engineers can optimize control algorithms by simulating real environmental conditions and perform non-destructive excursion testing for unsafe external fault conditions ( like the melting of motor windings) and evaluate the unit’s response. For today’s EVs, it is essential to find testing solutions that support higher voltages with the flexibility to support both low- and high-current units that require power switching. With expertise across electrical propulsion systems and thermal management, we can strategize the right methodology as powertrain systems evolve.

With far more electronics than traditional vehicles , EVs have a large array of sensors in the engine compartment, cabin, and exterior to provide feedback on the environment . These essential sensors and the systems that manage them require responses to many different signal types. Key testing focuses include switching the diversity of sensor signals, working with higher frequency signals compared to internal combustion engines, and sensing speed and environmental factors versus engine performance. Our expertise lies in discerning the right methodology to test sensor and management systems as EVs evolve.
