| You might
already be aware
that auto makers had spent considerable time and effort in engineering
zero emission vehicles to address the requirements enforced by CARB in
the last half of the 1990's.
Each of the
big three US
auto makers offered a Battery Electric Vehicle version of their
standard
ICE lineup. It was only GM who used their considerable resources to
design
an Electric Vehicle from the ground up.
General
Motors offerings
were the EV1, and the S-10EV. Both vehicles used identical drive
train components. The EV1 was offered as a lease-only vehicle,
unavailable
for sale to the general public. These were an amazing car, and
delivered
a practical mileage between charging. And charging was safe and
simply
accomplished using the Magnecharger Inductive charging system.
No EV1's
are operational and being driven on our highways today.
The
Chevrolet S-10EV was
offered as a fleet-lease vehicle to various Governments and utilities
in
volume. A total of 492 S-10EV's were assembled. Of those,
approximately 60 were sold and titled. The title permitted these trucks
to be
privately
owned. Unfortunately all others have since been destroyed.
This truck
may look identical
to it's gasoline powered sibling, even though it is radically different
underneath the skin. The S-10EV is FWD and powered by a 85kw, three
phase AC motor, delivering up to 112 horsepower. Two battery
chemistries
were offered for the S-10EV; (1) an obsolete VRLA (Valve Regulated Lead
Acid) battery by Panasonic, and (2) the GM/Ovonic Nickel Metal Hydride
battery. With NiMH delivering nearly twice the energy density, and 3X
life, over
conventional PbA (Lead-Acid) batteries.
Lithium-Ion
battery technology
is continuously improving, and may be a financially viable traction
drive battery
alternative
to the NiMH chemistry in another 2-3 years.
