|Location||Indianapolis, 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||22 Odyssey PC2150, 12.00 Volt, Lead-Acid, AGM|
Plenty of power for my 25 mi commute to work!
|System Voltage||264 Volts|
|Charger||Manzanita Micro PFC-40M|
PFC-40M 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 3 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 voltages.
Future Tech: Power consumption graphics envisioned, Radio & podcast integration, with Bluetooth mobile phone connectivity slated for "any year now" implementation.
|Top Speed||100 MPH (160 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||50 Miles (80 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 "console"|
|Tires||Nitto NeoGen 225/50 ZR17 - Wider Is Better!|
(Great low rolling resistance per Consumer Reports testing)
|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||Budget target: < cost of 2007 Toyota Prius|
Blew that a few months ago!
|Additional Features||Wireless internet access enables home (& eventually destination) synchronization of on-board software and media. Alerts / remote monitoring of battery charging while at work since not 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 lots.
|Purchased June 2007|
Officially started commuting: Sep 18, 2008
Still finishing interior & carPC installation
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 price.
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
To be completed within the next decade:
o Replacing transmission and front CV shafts to reduce suspected worn gears & bearings (currently underway)
o Belly pan (instead of belly tarp :-)
o A more custom dash installation of the carPC to lose the project car "look"
o Window tinting, & paint job!
