Nearly 10.000 electric vehicles have emerged from the French car fleet during these 15 last years. The presentation details the accumulated experience on these vehicles, to highlight the technical points that limited the performances and to analyze the technological accessible progress. The reliability weakness of the batteries, and of course its cost effect, is the main problem that has been met with this kind of vehicles. The initial expensive price of batteries, combined with poor cycles endurance, induce a kilometric cost two to three times higher than the one of traditional gasoline vehicles. Some problems on the electronics and on the traction motor were also noticed. In CEA-LITEN the native Ni-Cd batteries of a Citroën AX was replaced with high security Lithium Iron Phosphate batteries.
