Abstract
This paper focuses the development of an electric vehicle (EV) from the chassis of a Mini 1000. The vehicle uses two permanent magnets electrical machines coupled to the front wheels to achieve traction. The variation of the motors speed is allowed by two power electronic DC/DC converters connected to the batteries. Due to the high currents evolved there were several implementation problems. The solutions encountered are explained in this paper. Safety vehicle operation was an important issue to be achieved.
