DC/DC Converter HP DL320 Server Power Supply
Converted HP DL320 Server Power Suppply.
Simply bypassed the bridge rectifier to
connect up the the 144V traction battery.
Biased up the 12V output to 13.4V and
connected the logic so it turns on.
Used a 12V/144V relay so it runs only when the
car's keyswitch is set to ON.
InstrumentationAnalogue Amp/Volt meters where the oil pressure
and engine temp dials used to be.
Fuel Gauge Coulomb counter drives the original
fuel gauge
Top Speed75 MPH (120 KPH)
Tested up to 120km/h on the freeway here.
Felt like it had a bit more in her but with
all the traffic cameras in this city it's a bit hard to test!
Acceleration0-60km/h (0-40mph) better than original
60-100km/h (40-60mph) is not bad but not as good
as original ICE. Still testing
Range45 Miles (72 Kilometers)
My commute is about 22km (14 miles) each way
so still have plenty left in the tank each
With all the space left in the rear and front,
if I did it all over again, i would use larger
batteries so that I would get to

The conversion was a much longer, more involved process than I
thought. I almost gave up so many times :0)

Now that it's all (mostly) done, I love it. The car is quiet but
powerful and with all the batteries between the axles, is a dream
to drive. The EV grin is real and is alive and well down under..

I love taking people for drives in it and watching their faces
when we come to the first intersection and the whole car goes
eerily quiet, as if it's broken down. It seems to freak people
out even more than the initial take off.

Aside from the electrical conversion, the auto restoration came
out a treat. The car never fails to turn heads even before the
bonnet comes up to reveal the electrical power train.
