The experimental measurement of the energy consumption and efficiency of Battery Electric Vehicles (BEVs) are key topics to determine their usability and performance in real-world conditions. This paper aims to present the results of a test campaign carried out on a BEV, representative of the most common technology available today on the market. The vehicle is a 5-seat car, equipped with an 80 kW synchronous electric motor powered by a 24 kWh Li-Ion battery. The description and discussion of the experimental results is split into 2 parts: Part 1 focuses on laboratory tests, whereas Part 2 focuses on the on-road tests. As far as on-road tests are concerned, the vehicle has been tested over three different on-road routes, ranging from 60 to 90 km each, with a driving time ranging from approximately one and half to two and half hours.

The description and discussion of the experimental results is split into 2 parts: Part 1 focuses on laboratory tests, whereas Part 2 focuses on the on-road tests. As far as the laboratory tests are concerned, the vehicle has been tested over three different driving cycles (i.e. NEDC, WLTC and WMTC) at two different ambient temperatures (namely +25 °C and −7 °C), with and without the use of the cabin heating, ventilation and air-conditioning system.

The Municipality of Rome stimulated the introduction in town area of innovative and demonstrative large fleet of scooter for personal transports, referred to the electric technology. This experience was motivated by the need of a real evaluation and characterization of an innovative technology that yields promises of reduction of pollutant emission and of energy saving, in view of a possible massive introduction in the congested and polluted urban areas. This paper reports the results of this real experience in terms of the fundamental performances of these scooters (energy consumptions, reliability) and demonstrates also how the experimental results can constitute a feedback to the design phase to improve the vehicle performances. This experience also demonstrates that the electric scooter is a useful and practicable idea that confirms many of its presuppositions and takes on an important role in the innovative zero emission vehicle technology.
