The power conversion section of the EV / HEV is composed of several power electronic units, which include the EVSE (EV Supply Equipment), on-board charger, DC/DC converter, motor driver, etc. The Chroma ATS (Automatic Test System) addresses the specialized requirements involved in testing the power electronics during not only the development phase, but also the production phase. The benefits of our ATS are not limited to the reduction of manpower and prevention of human error; they also include advanced features such as automatic test data recording and creation of statistical analytical reports for later design review or product improvement. There are custom-built systems that are designed specifically for certain power electronic units; however, these systems are usually difficult to maintain and lack flexibility. These shortcomings will definitely impede the product development process as test methodologies evolve.
Mission-Critical Rapid Response: Power HIL System Tackles OBC Test Challenges
As electric vehicle (EV) technology advances, the on-board charger (OBC) has become a core module integrating power electronics and vehicle communications. Because architectures and protocols vary by OEM, test systems face varied and demanding requirements, especially in terms of real-time responsiveness and protocol handling.
