Vehicle1985 GMC Griffon
Basically a British Bedford CF2 Electric built with left-hand drive and badged "Griffon" for the import to the U.S.
MotorLucas MT-305 Separately Excited DC
216V, 40kW continuous
Drivetrain"Direct drive"
1.92:1 step-down via chain/sprocket drive from motor shaft to driveshaft.
4.89:1 rear axle ratio.
ControllerLucas Mark 4A
Large box sitting where engine would have been. Solid early 1980s technology. Very effective variable regenerative braking.
Batteries36 Interstate U-2000, 6.00 Volt, Lead-Acid, Flooded
Original traction batteries were Chloride tubular plate type. Nice batteries from what I hear, but were long gone by the time I got this van.
System Voltage216 Volts
ChargerZivan NG3
Also use a homebrew variac-based charger (120V input) for occasional mild equalizing charges
HeaterCurrently none
DC/DC ConverterLucas
216V nominal input, 14V output @ 25A max.
- Speedometer
- Battery SOC meter

I've added:
- +/- 250A ammeter to measure motor current (forward and regen)
- Battery pack voltmeter

Would like to add soon:
- E-meter for more accurate SOC readings
Top Speed55 MPH (88 KPH)
AccelerationDirect drive means good acceleration up to about 35 mph. Takes a while to get up to 50-55 mph unless you are going downhill. Doesn't take uphills at high speed.
Range40 Miles (64 Kilometers)
Have never taken it that far, but stock SOC meter indicated plenty of battery capacity remaining after a 20 mile drive.
Watt Hours/Mile800 Wh/Mile
A rough estimate... will have more solid numbers in the future.
Seating CapacityIn normal configuration with batteries in tray: 4 passengers (plus driver)

In current temporary configuration with bench seat removed: 1 passenger (it's the largest 2-seater EV on the road).
This van is currently in temporary configuration with the batteries inside on the bed (original bench seat removed). There is an original battery tray that hangs underneath the chassis. When I've painted the battery tray, I'll put the batteries back in it and re-install the bench seat.

Side mirrors are GM, not original Bedford. This van originally had Bedford mirrors, but a previous owner replaced them with the GM units.

Will post more photos of the interior when I've moved the batteries back into the tray, replaced the seat, and cleaned up the interior somewhat.

Thanks to my friend Dick Potteiger for spending hours restoring the long-neglected exterior paint finish.
