On November 14th-15th, 2019 the Society of Automotive Engineers of Japan (JSAE) hosted the 12th International CCS & ISO/IEC 15118 Testing Symposium in their facilities in Tokyo. Around 80 participants from different companies conducted interoperability and conformance tests with EV and EVSE communication controllers in order to make different technologies work reliable and smooth together on a diverse global market. The event received positive feedback and the CCS community is looking forward to the next event!
