C8000 Electric Vehicle Test System

The power conversion within an electric vehicle (EV) is composed of several power electronic units, which include the AC or DC EVSE (EV Supply Equipment), on-board charger, DC/DC converter, and motor driver. Chroma’s ATS (Automatic Test System) addresses the specialized requirements involved in testing the power electronics during the development phase as well as the production phase.

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.

  • Open architecture software platform
  • Support instrument with GPIB/RS-232 or RS-485/I2C/CAN BUS interfaces
  • User editable test item, test program, & report format
  • Statistical report
  • On-line control function
  • User authority control
  • Activity log
  • Master/Slave control mode
  • Multi-UUT test capability for single-output PSU
  • Support bar code reader
  • Support Shop-floor control
  • Remote monitoring via internet
  • Test command optimizer helps to improve test speed
  • Capable of coding for any power supply testing applications
  • Comprehensive hardware modules provide high accuracy and repetitive measurements
  • High test throughput by system default test items
  • Cost effective
  • Other hardware expandable upon request
  • Windows 98/NT/2000 or higher based software

The Chroma C8000 Auto Test System uses a unique test command optimization technology to prevent sending repetitive control commands to the system hardware devices. This improves system test speed dramatically and makes the Chroma 8000, which uses open software architecture, highly efficient as a closed or optimized auto test system.

To meet the power supply test requirements, the Chroma C8000 Auto Test System has 56 ready-made test items built in. Users may create new test items or edit existing items based on new test requirements using the test item editing function. This provides users the capability to expand testing ability without limits.

With powerful reporting, statistical analysis, and management functions, the Chroma C8000 Auto Test System is able to generate many test documents as well as allowing control of system administration tasks. Test results and statistical reports are equally important for R&D evaluation, QA verification, and mass production tests, and with these functions built in to the system a great deal of time is saved, reducing the amount of manual paperwork that must be completed.

Working under Windows 98/NT/2000 or higher operation system, Chroma 8000 Power Supply Auto Test System is able to get all the resources provided by Windows; thus, it can easily export the test results to network or to your web-page for remote manufacturing monitoring.
