Experimental Test Campaign on a Battery Electric Vehicle: On-Road Test Results (Part 2)

2015-04-14

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.

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).

Assessing Magnetic Fields in Electrified Vehicles: An Exploratory Campaign

Electrification is considered one of the key options to achieve a significant level of decarbonization of the road transport system. In particular, hybrid and electric passenger cars are seen as a concrete and already available solution to reduce CO2 and pollutant emissions from vehicles. However, new vehicle concepts pose new challenges in terms of procedures and methodologies for their type of approval. Current environment and safety-related regulations have been developed primarily for conventional vehicles and some aspects related to electrified vehicles have not been fully addressed yet. The possibility for drivers or passengers of getting exposed to significant magnetic fields, generated by high currents flowing in the car during driving or recharging operation is one of the real and potential issues currently under discussion and investigation.
