DC China Analyzer / Simulator
New challenges…
Advancing developments in e-mobility make vehicle and charging-system manufacturers meet new challenges. For example the Chinese standard GB/T describes the requirements on DC-charging-systems, electrical circuits and the communication protocol to control the charging process. By combining electric vehicles and charging systems of various manufacturer, different system-tolerances and disturbing influences may occur. The reasons of charge interruptions are very difficult to locate due to the long charging process.
...meet new solutions
The comemso DC China Analyzer / Simulator measures and verifies both - communication and load circuit - on standard- conformity over the complete duration of charging and captures all deviations. In this way it’s possible to identify non-conformity of charging and get the reasons for charge interruptions.
