Intelligent transport systems — Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) — Part 25: Electromobility charging infrastructure (TPEG2-EMI)

ISO/TS 21219-25:2017 defines the TPEG application electromobility charging infrastructure (EMI). It has been specifically designed to support information about charging infrastructure for electric vehicles (not just cars), the location of e-charging points and their suitability for the respective vehicle (e.g. connector type, charging modality). As electric vehicles will occupy a "charging space" for a longer period of time, information on availability/waiting time and reservation options are highly relevant for a user of an electric vehicle to optimally plan his route/trip and are therefore also accounted for.

The standardized delivery, through a TPEG technology, of information on charging infrastructures has the following benefits to an end user of this TPEG service:

a) Identifying suitable charging units for his vehicle, thus preventing unnecessary driving around to find a fitting unit (also has environmental benefits).

b) Verifying the real-time availability of charging units.

c) Being able to plan ahead and reserve a spot in a charging park and thus optimize the planning of his trip.

d) Being able to select a financially attractive charging point in a charging park the op
