The use of small electric vehicles (SEV) will increase significantly in urban areas over the next twenty years. The shape and mass of these SEVs show distinctive differences compared to the traditional car. The approach of the present study which is part of the SafeEV project is to simulate a large number of pedestrian and bicyclist accident scenarios involving SEVs, using multi‐body system and considering four SEV front‐end geometries at various speeds. A first idea coming from the project workgroup is to select three car shapes and to introduce two head impact speeds into the test methods (low travelling speed 30 km/h and higher travelling speed 50 km/h). The head impact conditions have been extracted in these accident scenarios with head impact velocities between 22 to 27 km/h at 30 km/h and 40 to 48 km/h at 50 km/h. The surface most often impacted is the windscreen with an impact velocity angle of about 30 deg at low speed. The results from both the project workgroup and the kinematic study should be considered in future standard test procedures when it comes to the definition of head impact conditions for SEV.
