Vehicle1991 Chevrolet S-10
Bought off Craigslist.org.

Came with a 2.8L V6 5 speed with AC.
Everything was working.

Calculated savings over my Diesel truck
was initially estimated at $3000-
3500/year in fuel alone, not including
maintenance savings! Those numbers
based on fuel costs of $3.75/gal.

ControllerEvnetics Soliton 1
Regen: No
Batteries50 SE200AHA, 3.20 Volt, Lithium Iron Phosphate
Built battery box with 2" steel angle
for the bottom and 1.5" x 1/8" aluminum
angle for the corner posts, 1" angle
for the frame top. Used aluminum sheet
for the sides and 1/2" foam insulation
on all sides.
System Voltage166 Volts
ChargerZivan NG5
Charger operates at 208-240V single
phase so I can charge at work and home.

Charging is via a 50 Amp 250V "Recessed
Inlet" behind the gas cap cover.
HeaterCeramic 1500W from EV-America. It puts
out about 2100W on 144V, more with the
new voltage. Also lined the floor and
panel behind the seat with
radiant barrier.

Top Speed85 MPH (136 KPH)
This is the max on the speedometer. It
would easily go a hundred or more if I
tried. It would do 85 with the lead
batteries and original 500A controller!
AccelerationAwesome! Will spin the tires at 1000 amp setting but I've throttled it back to around 750.
Range100 Miles (160 Kilometers)
Range was calculated driving fairly easy.
With interstate driving speeds the range
is probably around 85 or so if not using
the heat but I usually keep it around 55-
65 or so and can go a little over 100 miles with no heat and conservative driving.
Watt Hours/Mile400 Wh/Mile
That is based on power from the utility
averaged over several months of driving with heat and lights at times and pulling a
trailer maybe 10% of the time. Not bad
considering the trailering!

Converted to Calb Lithium batteries April 2011 at Mileage
This is our company errand vehicle and my commuter. Doing
our little part to reduce pollution around Spartanburg, SC
and our dependence on foreign oil.

I hope to do a full size van when the battery technology
becomes affordable with AC drive and no transmission!

Since upgrading to Lithium batteries I'm using it a ton
more, averaging about 1350 miles/month and saving about
$325/month AFTER ALL EXPENSES. Due to losing several
hundred pounds in the upgrade, I've added a trailer hitch to
haul stuff on my small trailer as well.
