Vehicle2002 Porsche 911 Carrera 2 (996)
Picked this car up with a non-starting
engine. Perfect for a EV
retrofit! I found out after completion
the transmission was broken too, so I had
replace it.
MotorNetgain Warp 11HV Series Wound DC
Bigger than I expected, but awesome! Just
barely fits within the existing car frame
and existing transmission.
ControllerEvnetics Soliton 1
Batteries96 GBS 100Ah, 3.20 Volt, Lithium Iron Phosphate
I purchased 108 cells total, I only used 96.
All cells are in
series. 30.7KWh pack with 21.5kWh usable
accounting for 70% DOD.
System Voltage350 Volts
Charger EMW 10kW / 60A
I built the 10kW charger kit from
Emotorwerks. I purchased a complete PFC
stage. The system works great, it was
more work than expected getting it to
work. Next time I would purchase a pre-
built unit. So far I've only tested up to
6.6KW because that is the limit of the
available outlet at my house.
Heater2 Kats tank heaters (2KW each).
DC/DC ConverterAstrodyne SP750-12
I started with two Lambda/TDK power
supplies. One LS100-15 for the stuff that
is always on, and the SWS1000-15 for when
the car is started and it runs all the
accessories. I managed to blow these up
in a rainstorm, so I changed to the 750
watt Astrodyne model: SP750-12

Top Speed100 MPH (160 KPH)
I've taken the car to 100 MPH in 4th,
anything higher will have to wait for a spin
at the track because if you get caught going
over 100 MPH here, you lose your license for
1 year.
AccelerationAutomatic transmission is still a little
wonky, so I will time this once the quirks
are worked out.
First attempt at 0-60Mph was loosely
measured at 10.8 seconds(nothing to get
excited about)
Updated on 5/6/2013: Measuring with an app
on my phone resulted in 8.80 seconds.
Range60 Miles (96 Kilometers)
This was traveling at speeds of 50-60Mph.
Need to be able to get to the airport and
back home.
Watt Hours/Mile839 Wh/Mile
This was a 16 mile test of speeds ranging
from 70-100MPH. Temp was about 35F.

This is the pre-conversion starting weight.
Conversion Time11 months
Here are a few speed and associated range projections based on
my early tests:
70-100MPH = 32miles range
50-60MPH = 60miles range
