This VDE application guide specifies the minimum requirements for communication between a charging equipment with one or more charging points for electric road vehicles and local energy management behind a grid connection point, taking into account the requirements of the grid side (e.g. FNN). It contains the necessary information for energy management. In the future, bidirectional charging will also be dealt with, taking into account the results of DKE adhoc AK 353.0.401. The present application guide covers a part of the identified need for standardization (LIL) of the priority roadmap Intelligent Load Management of the National Platform Future of Mobility (NPM), which was elaborated in the DKE adhoc AK 353.0.104.
This application guide focuses exclusively on the communication between local EMS and charging station, but does not define any necessary electrical safety requirements that are necessary for proper use.
This application guide is agnostic to other communication standards series and established industry standards in the field of electric road vehicles, such as IEC 61851, ISO 15118, or OCPP 1.6 and 2.0.1 or IEC 63110.
For the present application guide, an initial prioritization of user stories and use cases has been made. The highest prioritized cases are described in this edition; others will follow in later editions.
