COMEMSO

EV Charging Analyzer / Simulator (AC/DC)

Comemso meets new challenges with high quality

Developments for e-mobility present new challenges for vehicle- and charging-system manufacturers. Through a high availability of the 230V AC main power supply, conductive charging systems for electric vehicles are widely spread. The quiet young standard IEC 61851 and SAE J1772 describe the requirements on AC-charging-systems, electrical waveforms and the pilot signal to control the charging process. By combining electric vehicles and charging systems of various manufacturer, different system- tolerances and disturbing influences may occur. The causes of charge interruptions are very difficult to locate due to the long charging.

The comemso EV Charging Analyzer / Simulator measures and verifies both the communication and the load circuit on standard-conformity over the complete duration of charging and records all deviations. Thus causes of charge interruptions can be identified and also causalities of events can be detected and visualized.
