Current status and future trends in More Electric Car power systems

Voltage Stability Analysis of Automotive Power Nets based on Modeling and Experimental Results

“…The advantages of higher voltage power nets, e.g. the proposed 42 V system, were clearly shown in (Miller et al, 1999;Miller & Nicastri, 1998;Lukic & Emadi, 2002), but the automotive industry mainly stuck to the conventional reliable 12 V power net. From the view of voltage stability analysis, multi level power nets are only two separated single level power nets coupled by an energy converter like a DC chopper converter.…”

Electric car chassis design and analysis by using CATIA V5 R19

“…In the European Union, the car manufacturers have agreed to an overall 25% increase in fuel efficiency by the year 2005 compared to 1990 [1]. In addition, concerns over climate change and reduction of greenhouse gas emissions, and dependence of economies on foreign energy sources, have also become an initiative for extensive research on the use of electric cars as an alternative [2,3,4]. Quality has been one of the key issues for the automotive industry.…”

Experimental Characterization of a Supercapacitor-Based Electrical Torque-Boost System for Downsized ICE Vehicles

“…However, it is widely accepted that a significant reduction will only be achieved through technological advances in the automotive sector. This has led to significant development in hybridization of vehicle power trains [1]- [3] via series, parallel, and series-parallel formats [4], [5]. One effective approach is engine downsizing, since a downsized internal combustion engine (ICE), which has high specific power by turbocharging (TC), has the potential to reduce fuel consumption by ∼30%, as compared to that of a naturally aspirated (NA) ICE with ∼65% higher displacement.…”
