Vehicle1997 Toyota 4Runner Limited
1997 Toyota 4Runner limited SUV converted to an electric vehicle (3 phase AC) with all bells and whistles.
MotorAzure Dynamics/Solectria AC-90 3-Phase AC
This three phase Induction Motor has ample power as it is designed to pull a 10k pounds box truck or a delivery van.Peak shaft power is 100 kw,continuous shaft power is around
50 kw.
DrivetrainChanged to Manual 5 speed transmission with clutch, so that I can change gears if needed. But with this change the Limited Toyota SUV is now a two (rare) wheel drive. I
have
been driving fine with just gear shift lever
set to 4th gear.
ControllerAzure Dynamics/Solectria DMOC 645
Controller and motor are air cooled.
Batteries100 CALB/Skyenergy 180FI, 320.00 Volt, Lithium Iron Phosphate
This is a 57 kw Battery pack when fully charged. I usually use it between 95% - 10% SOC window.
(weighs 1250 lbs)
System Voltage320 Volts
ChargerElcon PFC 5000
5 kw CAN Bus controlled charger programmed to 370 volts max at 15Amp charging current (runs off 240 volt AC supply)
Heater480 volt 3kw dual coil inline liquid heater with a coolant pump connected to vehicle heater core.
DC/DC Converter TRC 600-12
TRC electronics 320 volt to 12 volt 53amp
converter (air cooled).
InstrumentationTesting it now with my laptop connected to Orion BMS. Will probably do a touch screen based display later.
Top Speed78 MPH (125 KPH)
I have Tested the vehicle at 78 mph. Probably can do quite a bit more as I did not floor it yet (I have also not tuned the controller yet).
I do not want to get a ticket.
AccelerationIf I drive it as manual, can accelerate to 60mph
in less than 7-8 seconds.
Range145 Miles (233 Kilometers)
145 miles if I discharge it to 7% SOC. For 80% Depth Of Discharge (DOD), I get about 125 miles.
Watt Hours/Mile370 Wh/Mile
Draws between 360-410 watt hours per mile
depending on hills and speed.
EV Miles
Start:123,340 Miles (198,454 Kilometers)
Current:135,404 Miles (217,865 Kilometers)
Total:12,064 Miles (19,410 Kilometers)
 
    As of 3/26/2017
Seating Capacity5 adults
Curb Weight4,200 Pounds (1,909 Kilograms)
About 4200lbs (estimated). Will take the giant
sometime to a weigh-bridge.
TiresBridgestone 70R16
Conversion TimeAbout 2 years (I have a day job to pay for this).
Conversion CostAbout $40k (I have not confessed this number to my lovely wife yet and yes, I am still married).
Additional FeaturesImplemented MR2 2002 Electrical steering pump to get power steering working with custom pressure hose adapters. A baby can steer this beast now.

I have also added after market seat warmers and steering wheel heater. It is a limited edition 4Runner, remember.AC and instrumentation - will add soon.
This is my second conversion. I have a ZAP Three wheeler that I kitted up with Curtis AC controller and 3 phase AC motor before taking the plunge on 4Runner conversion.
