IEC TC 57 just published the 70+ page draft (57/1603/DTR) for comments:

IEC 61850-90-8 TR:
Communication networks and systems for power utility automation –
Part 90-8: Object model for electric mobility

Voting terminates on 2015-09-25

This technical report describes how current standardization for Electric Road Vehicles (EV) and the Vehicle-to-Grid Communication Interface can be linked to IEC 61850-7-420 standard for Distributed Energy Resources (DER). The technical report provides necessary background information and proposes an object model for E-mobility in order to establish an EV plugged into the power grid as DER according to the principles of IEC 61850-7-420. The basic information modeling in IEC 61850 and IEC 61850-7-420 already covers a lot of needs for the e-Mobility domain. Missing parts can be modeled as new logical nodes and data objects, which this technical report defines.

Scope
The scope of this document is to show 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.

Here is an overview about the topology of the logical nodes required (existing and new ones):

Standards are key for E-Mobility and many other power application domains.
