MotorAzure Dynamics/Solectria AC24 3-Phase AC
DrivetrainFWD, previously a 1.0 L 3 cyl
ControllerAzure Dynamics/Solectria DMOC445
Batteries72 GBS 100 Ah LiFeMnPO4, 3.20 Volt, Lithium Iron Phosphate
After a couple of lead acid packs (156V) we
upgraded to a fantastic Lithium Ion pack.
the range, less weight, more power, faster
acceleration, and will last 2-3x longer. Best
decision we've made.
System Voltage230 Volts
ChargerElcon PFC 2500
Upgraded from an excellent Manzanita Micro PFC-
20 to an ElCon PFC 2500, with Can BUS.
HeaterThought about getting a small heater that plugs
into the lighter socket but never got around to
it - its So. Cal. so we don't need a heater
DC/DC Converter Hood-mounted Solar Panel
Previously used a CC Power C400 model
but it suddenly stopped working. I
know this model works well for many
people but I decided instead to use a
solar trickle charger to recharge the
house battery. I also installed a basic 12V
onboard charger, when the traction pack
recharges so does the 12V.
Instrumentation3 pack from ElectroAutomotive: 6-16 volts for
the house battery; 115 - 175 Volts for pack
voltage (serves as "fuel" gauge); and
-200.0.+200 Ammeter (see photo of these in
Top Speed90 MPH (144 KPH)
With lighter batteries, acceleration is really
good and I can drive on freeways with ease.
AccelerationMuch better than the old 3 cyl.
Range100 Miles (160 Kilometers)
Previous range with the lead batteries ws
about 35 miles of fwy driving, 45-55 miles
around town depending on hills, driving style,
etc. Now I can comfortably go 100 miles with
typical driving, and if I hypermile I can go
much further.
Watt Hours/Mile260 Wh/Mile
Rough estimate.
EV Miles
Start:188,300 Miles (302,974 Kilometers)
Current:214,400 Miles (344,969 Kilometers)
Total:26,100 Miles (41,994 Kilometers)
Seating Capacity2 adults (took out the back seat for
Curb Weight1,859 Pounds (844 Kilograms)
Prior to conversion process, about 2,500 with
lead acid batteries.
TiresPut new Falken ZE-512 (low rolling resistance)
195/60R15s on the Acura rims that the previous
owner got. They work great! Even steering is
easier when stopped (since the car never had
power steering, that is a good thing).
Conversion Timetoo long (our first conversion, so
everything is a learning process :)
Conversion CostVehicle - donated
A/C Kit from EA - $11K
Brakes/Suspension - $500
Batteries - (lead acid, x2) $2,500
New Li-Ion batteries, BMS, Charger, etc - $12k
Elcon Charger - $700

Other misc:
Pioneer audio/visual system - $250
AVCON Adapter - $250
Battery Box - $40 from a friend (thanks
Professional services (welding, wiring,
etc.) - approx. $2,500
Additional FeaturesInstalled interface to the Azure Dynamics Controller in the cabin,
makes it easier to get readings and make adjustments.

Added a solar trickle charger for the house battery, to
replace the DC to DC converter which suddenly went dead.

(Installed the AVCON adapter into the vehicle; then upgraded to

Installed Pioneer AVH-X2700BS system, for bluetooth connection to
my phone, much better sound system and mirroring of phone app for
new BMS, etc.

Oh, and really cool "Knyght Rider" inspired lights:
Installed A/C Light Vehicle Kit from Electro Automotive

Got new Li batteries, BMS and charger from Electric Motor Sports
