Performance Analysis of Current BEVs - Based on a Comprehensive Review of Specifications
Artikel i vetenskaplig tidskrift, 2016

This paper aims to provide an analysis of BEV performance that is based on a comprehensive collection of specifications of over 40 currently globally available battery electric vehicles (BEVs). The analysis comprise dimensional, powertrain and performance data. The collected data is provided in the paper to facilitate further academic studies. There is a wide variety of BEVs from small to large as well as high performing sedans and sport cars. It was found that all BEVs are using Li-ion batteries with specific energy of 55-170 Wh/kg, and that battery weights are representing 13%-37% of the vehicle weight. Furthermore, the majority of the BEVs are using permanent magnet motors, where some indicate power densities of 1.5-3.1 kW/kg. The specified NEDC driving range varies between 85- 528 km, and the energy consumption between 117-268 Wh/km. A rough estimation indicates that the powertrain’s share of the net energy consumption during NEDC may be up to around 40%-54%.
