Since 2011, smartlab has been active in intelligent and connected e-mobility and involved in research projects to further develop this emerging field. From earlier projects, smartlab has been able to succesfully develop both the German ladenetz.de charging infrastructure network of municipal utilities with more than 150 members as well as the e-clearing.net European roaming platform. evRoaming4EU further expands the activities on the European roaming landscape by further developing OCPI and e-clearing.net to integrate the open protocol alongside the native OCHP for even better use with roaming platforms.
