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 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 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.

Regulated gaseous emissions from two Euro 3 motorcycles and three Euro 5 passenger cars were measured over different driving cycles. The purpose of this study was to get data on typical emission levels and patterns of motorcycles and passenger cars currently circulating on the road in Europe. In respect to this, three driving cycles were selected: the current type approval driving cycles used to certify the test vehicles for emissions (NEDC for passenger cars and the EDC for motorcycles) and the world-wide harmonized driving cycle for motorcycles (WMTC). The gaseous emissions (NOx, HC, CO and CO2) were measured using the typical type approval test procedure for light duty vehicles. Since all the vehicles tested had been certified using the relevant current legislative cycle (i.e. NEDC or EDC), these vehicles were presumably not optimized for the WMTC cycle.

Energy efficiency of electric vehicles (EVs) and the representativeness of different driving cycles are important aspects to address EVs performance in real-world driving conditions. This paper presents the results of an explorative tests campaign carried out at the Joint Research Centre of the European Commission to investigate the impact of different driving cycles on the energy consumption of an electric vehicle available on the market. The vehicle is a battery electric city-car which has been tested over the New European Driving Cycle (NEDC), the current version of the World-wide harmonized Light vehicles Test Cycle (WLTC) and the World-wide Motorcycle emission Test Cycle (WMTC). The tests are performed at different ambient temperatures (namely +23 °C and −7 °C) with and without the use of the Heating Ventilation and Air-Conditioning (HVAC) system (in cooling and heating mode, respectively).
