1. 21. Towards Low-Voltage, High-Current : A pioneering drive concept for battery electric vehicles

   Författare :Stefan Haller; Kent Bertilsson; Bengt Oelmann; Peng Cheng; Dieter Gerling; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low voltage; high current; EV; BEV; electrical machine; power electronics; MOSFET;

   Sammanfattning : The first electric low-voltage vehicles were constructed in the mid-19th century, but by the early 20th century they were progressively replacedby successors with internal combustion engines. As the consequences ofusing fossil fuels are better understood, our society is now transitioning back. LÄS MER

5. 24. Assessment and control of tonal components in electric vehicles

   Författare :David Lennström; Etienne Parizet; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Sammanfattning : New challenges arise for noise, vibration and harshness (NVH) engineers when electric motors are introduced into cars traditionally powered by internal combustion engines (ICE). The noise signature from an electric traction motor is characterized by speed-dependent high frequency tonal components due to electro-magnetic excitation. LÄS MER

7. 25. Energy Management Strategy Design for Series Hybrid Electric Vehicles

   Författare :Iman Shafikhani; Jan Åslund; Erik Frisk; Christofer Sundström; Giorgio Rizzoni; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy management strategy; ECMS; series hybrid; battery aging;

   Sammanfattning : Electrification of vehicles is an indispensable step in improving fuel economy and reducing fossil fuel emissions. In particular, hybrid electric vehicle market has gained popularity as one such reliable solution. LÄS MER
