ABOUT THIS ISSUE

Trends in
EV Propulsion
Components
and Systems
By Silva Hiti and Khwaja Rahman

ODAY, THERE ARE MORE THAN 1.5 MILLION
plug-in-hybrid and (battery) electric vehicles (EVs) on
the roads worldwide, a number you'll find cited in a
few of the articles in this issue. For comparison, in 2005, EV volumes were still measured in hundreds. The steep rise in the
number of EVs is the result of the joint efforts, over the past
decade, of governments and the automotive industry worldwide.
Now, Bloomberg New Energy Finance predicts that, by 2040, EVs
will take 35% of the market share of new car sales globally.
This is an exciting time for engineers in the EV industry; EV
engineering veterans can finally witness their long-term efforts
come to fruition, and newcomers are getting a chance to join an
industry that is taking off. However, before you make your choice
to join or to leave the EV industry, read the in-depth, historical
(and magical) analysis by Peter Savagian of whether we are finally
in an era destined to bring commercial success to EVs offered in
the "Technology Leaders" column.
In the rest of the issue, we bring you a selection of articles
from industry and university experts on the latest development
trends in EV components and systems. The articles describe the
state-of-the-art and incoming technologies and design trends
for major components of the electric propulsion: electric
motors, power electronics, and batteries.
The first article on motor technologies "Getting Rare-Earth
Magnets Out of EV Traction Machines" by Jahns offers a tradeoff analysis on the selection of motor types for an EV propulsion system, and it makes a strong case on why the
interior-permanent-magnet (IPM) synchronous machine is still
the favorite choice for production passenger EVs. As always, it
is the application requirements, such as low acoustic noise,
torque ripple, high torque, and power densities, that drive this
