Irizar, Solaris, VDL and Volvo have agreed to ensure the interoperability of electric buses with charging infrastructure provided by ABB, Heliox and Siemens. The objective is to ensure an open interface between electric buses and charging infrastructure and to facilitate the introduction of electric bus systems in European cities. The public transport community is preparing for electric buses in Europe and standardisation activities have started via the European body (CEN-CENELEC) and the international organisation for standardisation (ISO/IEC). European standards are expected to come in place in 2019 and international standards by 2020.
With the electric bus and infrastructure manufacturers now working in agreement, preferred interfaces will be opened for all market participants. They will be used for electric buses that make use of opportunity (fast charging at end stops) and overnight charging. The group is committed to contribute to European standardisation activities and to share experiences with CEN/CENELEC and ISO/IEC in order to establish a common European standard for electric bus systems. The objective is to facilitate the transfer to electric bus systems in cities to ensure reliability and compatibility across bus brands and charging systems. Other bus manufacturers and charging system suppliers are invited to join the cooperation.
