Abstract: In the present study, it is presented the dimensioning of the power required to start up a single-occupant electric vehicle with an autonomy of 35 km with an average speed of 60 km/h and a mass of approximately 700 kg. Dimensioning is based on the requirement of the basic and common needs of conventional vehicle users. Each of the elements is described and analyzed from the energy point of view where the energy of the vehicle supplied by batteries which as load support, use solar panels strategically located in the vehicle. By means of an electrical and electronic conditioning, this energy is supplied to a DC motor. The power of the motor is transmitted to the vehicle’s wheels through a sequential mechanical transmission which is regulated in different speed ranges to efficiently take advantage of the energy.
