How to Streamline EV Onboard Charger Testing

+ Essential Three-Phase AC Power Supplies

Validate EV Charger Power Conditions

Electric vehicle onboard charger characterization requires generating controlled single-phase and three-phase AC electrical conditions while monitoring charger response under different operating scenarios. The test setup must support accurate voltage and frequency programming, transient generation, harmonics analysis, and power disturbance simulation to evaluate onboard charger behavior across normal and abnormal charging conditions.

The measurement process involves applying programmable AC input conditions and analyzing voltage, current, harmonics content, and charger response during simulated power interruptions, surges, sags, and frequency variations. Accurate results depend on precise AC source control, stable waveform generation, synchronized transient sequencing, and automated data logging to capture charger performance across multiple IEC 61851 charging modes. Integrated harmonics analysis, waveform capture, and automated test execution capabilities enable efficient and repeatable onboard charger characterization and validation.
