The Focus Group Meetings of the CharIN e.V. took place from September 23rd to 27th, 2019 in Berlin, Germany. During the meetings, members of the five CharIN Focus Groups Grid Integration, Charging Connection, Charging Infrastructure, Conformance Test/Interoperability and Charging Communication exchanged information about latest developments and discussed further progress of the Combined Charging System (CCS).


This year, CharIN has started several important activities like the CCTS event at Dekra, the public request for proposals on High Power Charging for Commercial Vehicles and Automated Connection Devices. CharIN aims at even more taking the customers` requirements into consideration and improving the interoperability of products. The target is to create a CCS certificate presenting a defined level of conformity. Additional topics on the agenda were:

  • HPC Power classes update
  • 2nd CCTS event 
  • Recommendation for Plug and Charge regarding high power charging
  • Discussion of the certification process
  • Preparation of a V2G Demo

Overall, the Focus Group meetings were well perceived from international participants. There were valuable discussions on the table and additional networking possibilities with common dinners which successfully concluded the working days.


The discussed topics will be further developed within the individual Focus Groups during regular phone conferences in an agreed time schedule. All activities focus on achieving one central target: To draw up requirements for the evolution of charging-related standards and to develop a certification system that can be used by all manufacturers implementing the CCS in their products.
