Challenge X Winners Use Cobasys System
Students from the Virginia Polytechnic Institute
and State University took top honors by winning
the 2006 Challenge X: Crossover to Sustainable
Mobility engineering competition. The team from
Blacksburg, Virginia, was among 17 universities
from across North America who took part in the
second annual competition in this three-year engineering
series.
Virginia Tech’s winning combination was a
re-engineered 2005 Chevrolet Equinox split parallel
hybrid that used an advanced Cobasys nickel metal
hydride (NiMH) battery system, two electric motors,
and was fueled by E85 – an ethanol/gas blend
that reduced vehicle petroleum use by 74%.
The Cobasys NiMHax 336V, 70kW NiMH battery system
was chosen by Virginia Tech to support their hybrid
vehicle because of the ease of integration, compact
packaging and superior performance. Eight of the
17 teams in this year’s competition chose
a Cobasys NiMHax battery solution. Cobasys is
a joint venture between Chevron Technology Ventures
and Energy Conversion Devices.
