MotorAdvanced DC FB1-4001 Series Wound DC
30 HP continuous, 100 HP peak
Drivetrain9" DC Motor with original 5 speed manual transmission & 4.10 differential.
ControllerCafe Electric Zilla 1K-LV
With water cooling system and Hairball interface programmed for 550 Amp battery current limit.
Batteries24 Trojan T-145 UT, 6.00 Volt, Lead-Acid, Flooded
Deep cycle golf cart style, group GC2H. 6 under hood, 18 in the bed (good weight distribution). 2/0 battery cables w/ crimp-only terminals.
System Voltage144 Volts
ChargerZivan NG5
240 V, 30 A single phase input, with high-low charge selection switch to allow charging from 120 V, 15 A circuit via step-up transformer
HeaterCeramic
DC/DC ConverterIota DLS-45
With IQ Charger Module. Spec shows 108-132 VAC input, but works fine on DC.
InstrumentationXantrex Link-10 (formerly E-Meter) with WinLink software for data logging.
Top Speed70 MPH (112 KPH)
70 MPH on flat road.
AccelerationAbout the same as the 130 peak HP, 2.2L 4 cyl ICE when loaded to 4900 lb.
Range40 Miles (64 Kilometers)
50 miles under optimal battery newness, temperature, terrain and wind resistance. I typically limit my drive to 40 miles under normal conditions usually leaving a 20% reserve.
Watt Hours/Mile700 Wh/Mile
As measured at the grid charging station - but my charger is wasting about 16% in overcharging the batteries past their EQ voltage. Average commute speed is 40 mph with daily peaks of 45 mph, and occasional peaks of 60 mph.
EV Miles
Start:76,640 Miles (123,313 Kilometers)
Current:80,450 Miles (129,444 Kilometers)
Total:3,810 Miles (6,130 Kilometers)

Automatic 'Multi Flow' battery watering system by Liquid Precision. Removed AC & PS to conserve energy.

Wired for extensive data logging - Link-10 (E-Meter) has RS-232 output to WinLink software, each battery in traction pack can be measured separately while charging or under load, Zilla Hairball PC interface.

Plan to switch to a Manzanita Micro PFC-30 to replace the Zivan NG5. The NG5 wastes about 16% of the charge energy and 1/3 the time in charging the batteries past the equalization voltage. Not only wastes energy, but boils more water.
What I Like:
1/3 the fuel cost per mile.
Smooth, quiet acceleration.
Never stopping at gas stations.
Fueling at home.
Seldom using the clutch.
Nearly instant cabin heat.
No exhaust fumes.
No oil changes, radiator flushes, muffler/exhaust pipe repairs.

What I Miss:
Engine compression going down hills (may add regen braking later).
AM Radio reception.
