Abstract
The actual constraints related to the air pollution, fuel and energy consumption became essential aspects considered while improving the performances of the classic vehicles and developing the new generation of mild hybrid electric vehicles and electric vehicles. Also, assuring the dynamism of the vehicle became an important goal that need to be assessed by the automotive industry. Nowadays, one of the main focuses of the automotive researchers is developing innovative power supplies and composed storage devices able to assure the dynamism of the vehicles thus facilitating the transition from the classic internal combustion engine (ICE) vehicles to the new generation of mild hybrid electric vehicles (HEV) and electric vehicles (EV). A solution for the actual constraints can be a combined energy and power supply system composed of storage devices characterized by different time constants. The present paper is focused on describing a physical reduced scale prototype of an electric vehicle and its control strategies able to satisfy better the requirements for increasing the energy efficiency of the implemented and tested system. In this paper the role of the used storage devices and of the control strategies are emphasized. Also, the architecture of the system, the experiments performed and the preliminary results are described.
