Profiting by Cooperation within the Cluster

General:

Getting a comprehensive overview on ongoing and launching projects within the ICT for fully Electric

Vehicles

Sharing knowledge about technology for Electric Vehicles within an expert community

Learning to know the EV related initiatives and programmes from different European countries

Opportunities for common EV activities within the cluster, e.g. joint workshops, events

ID4EV specific:

Complementary technical areas identified in the funded projects ID4EV and MAENAD

Continental internal collaboration of representatives from both projects planned

Joint activities

Common events

Workshops
