Chroma’s Automated Test System (ATS) is designed for full function testing of ac level 1 and level 2 EVSE (Electric Vehicle Supply Equipment) defined by SAE J1772. The system integrates Chroma’s programmable ac sources to simulate the grid voltage variation. It controls the ac electronic load simulating the current loading state of an onboard charger. A switchable resistor board and oscilloscope are used to test compatibility of the control pilot signal between the EVSE and EV. Test items include voltage interrupt, pulse-width modulation (PWM) duty cycle, contact open, over current protection, etc. This ATS features open-architecture platform software, allowing users to expand test functions in the future.
Chroma Targets Next Gen EV Charging Standards with ISO 15118 20 and Liquid Cooled, High Current Charging Test Solutions
To address the testing needs of next generation charging communication and high power charging architectures, Chroma has introduced the Chroma 8000 EV & EVSE automated test system (ATS), designed specifically for simultaneous multi connector testing of DC EVSE (EV supply equipment), EV charging compatibility validation, and high current liquid cooled charging tests.
