BMW shows 75 mph electric scooter

::::by Wayne Cunningham July 30, 2012

In the last decade, BMW's motorcycle
division dabbled in scooters as a green
solution for crowded urban centers,
producing the C1 for a few years. Now
BMW is showing off the final fruits of a
new project, an electric scooter designed
to achieve the performance specifications
of a gasoline-fueled scooter.
The C Evolution is the third generation of
an electric scooter that BMW has
previously shown in concept form. This
two-wheeler uses an electric motor and an
8 kilowatt battery pack to drive the rear
wheel. BMW says that it can go 62 miles
on a full charge. Although a large battery
back, it does not use liquid cooling.
Instead, its casing channels air through the
individual cells. As the batteries produce
more heat under load, the C Evolution
should be going faster as the batteries hit
higher temperatures, improving the air
flow.
BMW also designed the C Evolution for a
top speed of 75 mph. Anti-lock brakes are
one technology borrowed from BMW's
extensive experience building
motorcycles. However, the C Evolution
also uses brake regeneration, which helps
account for its range. A single swing arm
supports the rear drive wheel, which is
turned by a shaft. LED lights decrease the
load on the battery, and the rider gets
speed and battery status from an LCD.
Interestingly, BMW incorporates a J1772
charging port, the same as used in new
electric cars. The C Evolution can be
charged to full in three hours.
BMW is using the C Evolution as a test
prototype in real world situations. The
company says it plans to offer a
production version in the near future.
