CHAdeMO principles for evolution
▪ Adaptation (as flexible as possible)
▪ Backward compatibility
▪ Core values
Varied charge needs
Enhanced V2XFunctionality
High Power Charging(50kW+)
DC charge at home/office (6-10kW)
Battery as energy device• Peak cut• PV connection• VPP participation• Resilience• Leisure
Varied charge needs(22kW, 50kW, inductive, smart charge..)
• Full charge• Top-up• During stay• Low Power (low cost) • Charge guided by AI

o CHAdeMO is the first and the only international protocol to
enable V2X with production EVs / PCS
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
adapting to the various market needs around charging /
discharging
