|Location||Carmel, Indiana US map|
|Vehicle||2000 Honda CR-V|
|Motor||Netgain WarP 9 Series Wound DC|
Very pleased with the power produced by
this 9" to propel my sled. Hamstra
thought two might be req'd given my
situation, but one is all it takes!
Also use the forced air band & Dayton
blower on the CE to ensure min airflow.
|Drivetrain||5 Speed Manual Transmission w/ Real-time 4WD|
|Controller||Cafe Electric Z2K-EHV|
|Batteries||18 Sears DieHard PM1, 12.00 Volt, Lead-Acid, AGM|
Odyssey PC2150's manufactured for Sears
|System Voltage||216 Volts|
|Charger||Manzanita Micro PFC-50M|
PFC-50M bulk charger w/ MK3 DigiReg shunts
to ensure between 14.7-15Vdc finish charging
of AGM batteries (per their spec).
|Heater||Dual ceramic 220V heaters|
|DC/DC Converter||Iota DLS-220-55|
Dual Iotas provide 110A and some redundancy
(surprisingly reliable operation over 4 yrs
with my bone-jarring stiff suspension)
|Instrumentation||Analog: Westach Voltmeter 200-400V & |
Ammeter 0 - 1000A
Digital: On-board carPC allows display of
individual battery & overall pack
Future Tech: Power consumption graphics
envisioned, Radio & podcast integration,
with Bluetooth mobile phone connectivity
slated for "any year now" implementation.
|Top Speed||85 MPH (136 KPH)|
Estimated. Speedometer/odometer STILL not
functioning! Speedo good, electrical signal
present, but still driving by tachometer :-)
|Acceleration||Surprisingly good for a heavy sled... |
slightly slower than stock only because I've
dialed down motor amps to 600A max.
|Range||40 Miles (64 Kilometers)|
Designed vehicle for 50 mi range, but
estimate I hit 20% SOC at 40 miles.
Charging at work & home after my 25 mile
each way commute working well.
|Seating Capacity||4 seats - OEM frames w/ new leather |
upholstery. Regular front buckets, but
narrower rear buckets with a wide center
"arm rest" doubling as a battery rack
|Tires||Nitto NeoGen 225/50 ZR17 - Wider Is Better!|
(Great low rolling resistance per Consumer
|Conversion Time||15 months from purchase to start of reliable |
commuting (that's what happens when you're
already working too much before you get the
crazy idea to build an EV!)
|Conversion Cost||Approx. $30,000 incl tools|
|Additional Features||Wireless internet access enables synchronization of on-board |
software and media. Automated alerts / remote monitoring of
battery charging while at work not yet functional. Need to
step up to different wireless technology to achieve.
Battery HVAC solution designed & components purchased
(primarily heating batteries in winter), but implementation
delayed to phase 2.
Toyota MR-2 power steering efficiency upgrade (P/S ECU, P/S
Driver, Relay, Steering Sensor) delayed to phase 2.
Components (finally) all purchased...but a simple on/off switch
for the P/S pump has been working just fine in the parking
|Purchased June 2007|
Officially started commuting: Sep 18, 2008
Midwest Electric Vehicles (317-247-5684) has been an
excellent EV Builder / partner throughout this whole creation
process. [that's Nick in the bottom picture]
EV Source (Ryan Bohm) has been a great parts provider and
much more...excellent guidance and customer service.
Indy Custom Machine created the custom trans-motor adapter
and aluminum flywheel...exceeding my expectations in
delivering near "work of art" pieces at a very reasonable
o Zilla Z2K & WarP 9 motor successfully & reliably propelling
a heavy conversion for my 25 mile commute! Major
accomplishment as NetGain expressed concerns the WarP might
not handle the load, but it's doing GREAT.
o Brakes & power steering functional
o High voltage & low voltage wiring complete
o Suspension upgrade (Hypercoil springs)
o Gauges (tach, volt & ammeter) installation
o Resized & reinstalled rear seats. Gibbs Auto Interiors
offered a great deal for leather upholstery.
o New windshield
o Battery box cover for interior "battery console"
o carPC functional, but installation is crude
o Secure, enclosed mounting of on-board battery charger
o Dropped propeller shaft, rear differential, & rear axles in
the never-ending pursuit of low friction for max range
o Replaced transmission & front CV shafts
To be completed within the next decade:
o Belly pan (instead of belly tarp :-)
o A more custom dash installation of the carPC to lose the
project car "look". Likely integrate Windows tablet PC in
dash since resolution is so superior to my current
