People mover
MotorAzure Dynamics/Solectria AC55 3-Phase AC
Air cooled. Motor controller max shaft power is 65kW (87 Hp).
Stock vehicle was 67Hp.
DrivetrainStandard 4 speed transmission
ControllerAzure Dynamics/Solectria DMOC 445
Air cooled
Batteries110 CALB/Skyenergy SE60AH, 3.30 Volt, Lithium-Ion
60 Ahr, sags to about 340V under around 150 amps. eLithion
BMS system. About 21kWh.
System Voltage364 Volts
ChargerManzanita Micro PFC50
Probably a little overkill, but I can sure charge fast.
Heater2@1500 W PTC heaters. About 5.5 amps at low fan and 9
amps at high fan.
DC/DC ConverterVicor V375A15E600BL
600 W, brick. Raw device, have to add a number of items to
make it usable.
InstrumentationV and I gauges. Rabbit micro recording serial output DMM's
(TP4000ZC), its onboard ADC and the BMS serial output. Data
sent to an LCD as well as Wifi so that the iPhone can be used
as a display.
Top Speed75 MPH (120 KPH)
Keep it slow to conserve batteries but can hold with traffic
fine.
AccelerationCan be peppy now that I shed 900 lbs going from lead to
lithium
Range60 Miles (96 Kilometers)
Longest drive so far with the new batteries is about 54 miles
with zero notice of a change in voltage sag (freeway driving)
Watt Hours/Mile450 Wh/Mile
Wall-to-wheel. Battery to wheel varies between 350 Wh/mi to
420 Wh/mi, without regen on freeways. In city with regen will
be much better.
EV Miles
Start:88,668 Miles (142,666 Kilometers)
Current:104,630 Miles (168,349 Kilometers)
Total:15,962 Miles (25,682 Kilometers)
 
    As of 7/21/2010
Seating Capacity7
Curb Weight3,800 Pounds (1,727 Kilograms)
Vehicle weight with lead was 4700 lbs, so lost 900 lbs going
with lithiums.
TiresLT215/75R15, 50 psi, 100/97R, Load Range C.
Eventually will change to smaller dia and narrower.
Conversion Time9 months official start to first drive, but more months to get
the bugs out. Its a hobby.
Conversion Cost~$20k. Could have been less, but I now I am well stocked on
bits-n-pieces for the next conversion.
Additional FeaturesBattery boxes sunk into body for minimal intrusion into passenger area, and to give
lowest CG.

4.3kW of solar on my roof gives about 5000 kWh/year. 12,000 miles @ 450Wh/mi
consumes about 4700kWh/year.
Lots of fun, lots of work, lots of getting yelled at by my wife for $$'s and time.
