<div class="htmlview paragraph">The development of zero emission vehicles requires new concepts of the electrical drive train. On one hand the vehicle performance for a Californian electric vehicle must give high acceleration values together with enough vehicle range. On the other hand the expected battery performance will be an extreme limitation of capability. In this paper a comparison of an induction motor drive system is given for different working conditions and batteries such as Sodium Sulphur, Sodium Nickel Chloride and Nickel Cadmium.</div> <div class="htmlview paragraph">The results of simulations and practical experience show that exact vehicle predictions can be done if the battery effects such as internal losses and dynamic behaviour are taken into account.</div>
