IEC 61850-90-8 Models for Electric Mobility

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.

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.
