GM is primarily engaged in production of vehicles. It designs, manufactures,
markets cars, trucks and other automobile parts of world. GM has strong
portfolio which gives it significant advantage over competitive. Chevrolet Volt – the first ever extended range electric
vehicle which is built in Michigan at GM’s Detroit-Hamtramck Assembly. In
January 2007 the volt concept car was first proposed at North American International Auto
Show, becoming the first-ever series plug-in
hybrid concept car. The EV1’s of
the 1990’s were only two seated to reduce weight and to provide necessary room
for the lead-acid battery pack, when compared the Volt vehicle is a four seated
with a rear left gate. The top speed was also increased on the Volt, from 80
miles per hour to 100 miles per hour. The battery pack size was reduced, from
about 10.6 cu ft. in volume to 3.5 cu ft. The Production
Design model of Volt was officially announced on 16 September, 2008 at the
Winter Garden headquarters in Detroit. But this production model differed
significantly when to compared to the original volt Design. Once the concept was put
into the process of production, General Motors started looking for a partner to
develop the Volt’s lithium-ion battery pack. The Car Manufactures evaluated about 25 distinct
battery cell chemistries and constructions from around 2 dozen lithium-ion battery
makers around the world. Among them two companies were selected in June 2007
having most beneficial cell technologies, Compact Power, which uses a lithium
manganese oxide (LiMn2O4) cell made by its parent
company, LG Chemical and Continental Automotive Systems,
which uses lithium iron phosphate based cylindrical
cells made by A123 Systems.
The Compact Power delivered their finished battery pack prototypes by the end
of October 2007 and A123 delivered theirs by January 2008. The battery packs included monitoring systems designed to keep the
batteries cool and operating at optimum capacity despite a wide range of
ambient temperatures.
