EU-US evaluation of range extended electric vehicle performance at varying ambient temperatures

The US DoE Argonne National Laboratory (ANL) and the EC Joint Research Centre (JRC) collaborate to promote a common EU/US approach towards global harmonization of standards for e-mobility and smart grids, with a common work plan including pre-normative research on the energy efficiency of electric vehicles (EVs). The aim of this paper is to introduce the cooperative and complementary ANL-JRC activities focusing on chassis dynamometer testing of electrified vehicles. Within this research program, financed by the budgets of the Transatlantic Interoperability Centers at ANL and JRC, an extensively instrumented 2014 BMW i3 plug-in electric vehicle equipped with a range extending engine (REX), was evaluated at both the ANL's Advanced Powertrain Research Facility (APRF), and at the JRC's Vehicle electric Laboratory (VeLA 8). Testing was conducted against EU and US legislative cycles, in addition to operation-specific cycles with the vehicle conditioned and operating at varying ambient conditions from -30°C to 50°C. Data analysis focuses on both vehicle- and component-specific energy use across these varying temperatures and power demands.
