Grid-integrated EVs: demo to commercial applications
o CHAdeMO is the first and the only international protocol to enable V2X for production EVs
o More sophisticated multi-source home/office systems as well as large-scale pilots are being demonstrated and commercialised
o Having engaged in a variety of demo and commercial projects, CHAdeMO leads the innovation in the V2X domain
o CHAdeMO protocol evolves and optimises functionality with the lessons learned
