EV Power Conversion Testing

The power conversion within an electric vehicle (EV) is composed of several power electronic units. These include the AC or DC EVSE (EV Supply Equipment), on-board charger, DC-DC converter, and motor driver. Chroma’s EV automated test equipment addresses the specialized requirements involved in testing the power electronics of electric vehicles during design validation as well as production. The benefits of our automated test systems include flexibility, speed, and test data recording as well as providing statistical analytical reports for design review and product improvement.

Motors | Wound Component Testing

When electric vehicle motors are used for long hours under varying environmental conditions, durability and reliability are put to the test. Temperature is a key contributor in the break down of insulation. If corona discharge occurs in turn-to-turn and turn-to-ground, it would cause the insulation to deteriorate due to the increased heat. This directly impacts the motor’s quality. Adding Corona Discharge Detection in hipot testing exceeds the quality requirements for insulation by detecting units with poor insulation early on. Thus, greatly reducing the defect rate caused by long-term usage.
