This part of IEC 61850-90, which is a technical report, shows how IEC 61850-7-420 can be used to model the essential parts of the E-Mobility standards related to Electric Vehicles and Electric Vehicle Supply Equipments (IEC 62196, IEC 61851, IEC 15118) and the Power system (IEC 61850-7-420), in order to secure a high level of safety and interoperability. The namespace of this document is: "(TR) IEC 61850-90-8:2015" The name space "IEC 61850-90-8" is considered as "Transitional" since the model is expected to be included in the next edition of IEC 61850-7-420 1 . Potential extensions/modifications may happen if/when the model is given International Standard status. The most optimal backward compatibility with the original content will be strived for during this move. In accordance with the status of the ISO 15118 series and systems determined in IEC 61851-23 and -24, this technical report focuses on EV charging processes only. Discharging processes in order to support grid services are out of scope, but will be adopted when available in future versions of ISO 15118-2 and IEC 61851-1, -23 and -24.
