The communication between electric vehicle and charging infrastructure is standardized in the several documents of ISO 15118. One of the recently published parts is ISO 15118-20. In combination with part ISO15118-8 further charging options such as inductive and automated charging can now be implemented in professional solutions. Furthermore for wired charging solutions extended functions are available. Especially for bi-directional charging with AC or DC current and intelligent load management (dynamic or scheduled charging) valuable and future proof solutions supporting energy transition are provided. In this document the extended potential using ISO 15118-20 will be presented and a prospect will be given for further developments of the standard, i.e. support of megawatt charging systems.
