The URBAN-EV (Super Light Architectures for Safe and Affordable Urban Electric Vehicles) project aimed at nothing less than demonstrating the feasibility of key vehicle lightweighting technologies for the manufacture of light urban electric vehicles with new standards of mechanical performance and occupant safety.<\/p>\n\n

The main focus of URBAN-EV was based on combining the breakthroughs that drove innovation in affordable high-volume manufacturing of lightweight components, using pioneering material joining technologies, as well as testing and simulation capabilities.<\/p>\n\n

For the Urban EV project, which ran for almost 5 years and was funded under FP7-Transport, different work streams were created analyzing the first development approaches towards the urban model, and with a strong focus on weight management and vehicle safety.<\/p>\n\n

With these three factors in mind, a consortium of 10 partners was created, with the challenge of creating an electric vehicle with good performance and innovative materials: aluminum, magnesium, composite material and steel.<\/p>\n\n

Along the way, there were major challenges, such as the joining of different materials with each other.\nIn this aspect, innovative processes were used to join unconventional materials by electromagnetic forces.\nSince it was not possible to weld the materials, due to their different characteristics, nodes were created in order to be able to join them at supersonic speeds, where precision played an essential role.\nOne of the most important joints made was to join the magnesium with the structural material. <\/p>\n\n

All this was done with a complete vehicle design approach, in which all basic components were integrated as innovative design solutions.<\/p>\n\n

For the Urban EV vehicle, prototypes of a 2-seat urban electric vehicle were developed, with an optimal range and occupant safety level.<\/p>\n\n

Safety in urban vehicles<\/strong><\/h4>\n\n

As an important part of the project, the vehicle structure was optimized to be able to meet the requirements of a conventional passenger car.\nAppropriate safety simulations were performed based on the regulations, as well as specific restraint systems. <\/p>\n\n

Small urban car models, compared to larger cars, have a different energy absorption in the event of a collision. The importance of this project is that sufficient improvements were made to create a vehicle with a specific restraint system in terms of airbag, collapsible column, seat belts, door, etc. ….) where the stiffness and lightness of the composite or composite resins, and the strength and energy absorption of steel, make this vehicle a safe model.<\/p>\n\n
