Standardisation of ebus charging interface Teemu Raitaluoto “Electromobility in CIVITAS cities” 16/17 February 2016 – Cologne

Standardisation Motivation for the standardisation is to ensure the interoperability and connectivity for charging electric busses Currently tens of different solutions for charging The schedule for the standard prepared by CENELEC is strict Supply connectors and socket outlet by 12/2019 Wireless charging 12/2019 A lot can be learned from the standardisation of electric cars And bus charging standardisation can contribute to generalisation of electric harbor and mining equipment etc. 2

Use cases for standardization 3 Preparing the CEN/CENELEC standard according to M/553 for electric bus charging interface requires that ebus operation is described in the form of a use case document There are two use case documents written by VDV/UITP/VTT together – one for depot charging (plug) and the other for opportunity charging (fast charging) The documents explain how such a system is operated in general and what is to be considered when preparing the standard Use cases were collected from ZeEUS Demo site experts and members of the ZeEUS eBusses Standardization Steering Group Contributors and interested parties include bus manufacturers, charging equipment manufacturers, transport operators, energy suppliers, cities Technical aspects to be standardised later by CENELEC according to industry preferences Mechanical, electrical, communication protocols
