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).
InstrumentationHas SOC display and CAN Bus BMC to WiFi data logger. Can view battery and vehicle status on cloud service using any web browser.
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)

Curb Weight5,200 Pounds (2,363 Kilograms)
Beast weighs 5350 lbs as measured on North planes 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 more instrumentation - will be added 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.
