Get an overview of the entire scope of testing with reliable, precision instrumentation and systems including electrical safety testing for multiple applications.
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.
Chroma’s WPT test platforms and solutions have been globally adopted and recommended by the leading manufacturers of wireless charging solutions for electric vehicles.

Chroma’s EVSE test system is the world’s first UL approved SAE J1772 EVSE Communication Protocol Automated Test System. This system simulates various states of an EVSE to validate charging compatibility before delivery to the vehicle.
Electrical safety standards are increasing since new high-efficiency EV electronic components can drive up to 600V when in use. To insure end user safety, Chroma provides electrical safety test solutions for EV power components including wires and connectors, adapters, batteries and the charging system. With Chroma as a partner, you can be sure your products are compliant to standards and safe for the road.
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.
High precision, integrated battery test systems designed for lithium ion electric vehicle batteries or any chemistry. From R&D to production, Chroma’s battery test equipment provides advanced features. Features include regenerative discharge that recycles energy from the battery back to the channels in the system or to the grid. Systems are configurable and flexible with multiple channel capabilities and can be upgraded as testing requirements change.
