When You Look Under the
Hood of an Electric Vehicle
By Lee Stogner

hen you look under
the hood of an electric
vehicle (eV), you see that
the Ieee is the catalyst that makes
such a vehicle possible. you see computers, networks, software, power
electronics, control systems, batteries, and fuel cells. As individual pieces
without the standards that allow
them to plug into one another and
interoperate, these items could not
come together as a system or a tool
that can propel a car forward.
As it does with much of the other
electronic technology in the world,
the Ieee provides the standards and
existing technology that connect all
of the pieces of an eV together. This
platform can then be built upon and
enhanced to grow and meet future
challenges as we begin to better
understand what the eV needs to do.
In addition to developing needed
standards, the Ieee brings people
together via its publications, special
events, and conferences. These venues enable people to further develop
ideas and find out what the rest of
the world is doing with regard to eVs.
For example, the 2012 Ieee International electric Vehicle Conference,
which took place in Greenville, South
Carolina, was a valuable resource for
people and companies looking for
help or technical documentation.

This kind of communication is so
critical because the eV landscape
looks nothing like the current system. The company, or companies,
that will make a name for themselves in the eV industry in the next
five to ten years may not be one of
the world's major auto manufacturers. The winners will be companies
that can bring together the technology and make it affordable and usable.
They must also create a vehicle that
makes the average consumer want
to buy an eV as a first or second car.
As with all new technology, the
complexity of putting an eV on the
highway is going to reduce considerably as eVs' components become
more standardized. More players will
enter the market as eVs become easier to plug together and customize for
different customer bases. Today we
see single companies coming up with

I E E E E l e c t r i f i c ati o n M agaz ine / december 2013

ideas that make their eV special and
unique in the marketplace. We see
other companies that are willing to
partner with one another.
Whatever the business model, the
practice of holding back on new technology until you get a return on
existing technology is over. There is
so much competition in the eV arena
that companies are bringing their
solutions out as fast as they can.
They know that if they don't get
there first, someone else will. That
being said, there is definitely room
for more than one leader in the eV
market. Cars driven in one part of the
world will likely be different from
those in other parts.

Latest and Greatest
The ability to possess small, very
powerful electric motors is a recent
development that is helping eVs
move forward quickly. A standard
car has to warm up and then generate enough power to turn the
transmission and four tires, which is
terribly inefficient. The only thing
the gasoline-powered cars have
going for them is the reasonably
high density of energy they can get
from a gallon of gas.
At their core, eVs have very hightorque motors that allow the standard
1,000-lb power train to be eliminated
completely. The eV is much lighter, but
