The 9th International CCS & ISO/IEC 15118 Testing Symposium was hosted by NextEnergy in Detroit, USA. The first day served for different panel discussions about E-Mobility and its main pillars. The two next days built the actual Testing Symposium and helped the participants to resolve interoperability issues in the field of AC and DC charging. On day 4 of the event a Task Force worked on the CCS compatibility of Heavy Duty Commercial Vehicles. A great video footage was prepared by CharIN summarizing the event: VIDEO.
