It´s all about testing!

As members of a global community, CharIN e.V. has the responsibility to protect the welfare and health of all involved.

Based on the latest developments of the Coronavirus (COVID-19), various travel restrictions from member companies and the worries expressed by our members, we decided to amend our testival dates to provide the best possible conditions for a successful implementation of our event weeks.


The Combined Charging System (CCS) is a universal charging solution that enables EV fast charging, as well as integration of EVs into the broader electrical grid. CharIN’s mission is to establish CCS as the global standard for charging all kinds of electric vehicles.

For CCS to thrive on a global scale, achieving and demonstrating perfect interoperability between all CCS-equipped vehicles and CCS chargers is of paramount importance. Testivals play a major role in executing this goal.

The Testivals will take place in the USA, Europe and Asia, beginning with the Testival Asia in September. CharIN members will continue to tackle technical challenges that arise from a variety of implementations, individual use cases, and requirements.
