InstrumentationSpeedometer, PakTrakr, and BattEQ

Top Speed70 MPH (112 KPH)
Will not require anything over 60 mph, in fact, I don't intend
driving the car over 55 mph.
Acceleration44 -1500 (120VDC) Farad Maxwell Ultracapacitors
I will be using for acceleration and hill climbing. The
Ultracapacitors should take the car from 0 to 40 mph to
relieve the batteries from accelerations. If it works as
planned I will upgrade to 144 VDC with the batteries and
168VDC on the UCaps to get a little more power.




Range70 Miles (112 Kilometers)
This will be depend on what UCaps do to battery use.
If I can recharge the Ultracapacitors after each
acceleration, I
should be able to get the 70 mile range. I will be adding a
Honda EU2000i generator for recharging the UCaps, 12V
accessory battery, and a small heater.

Stage 1 is complete and the car was on the road and made it to 50mph with no
problems. The only thing left is to install the Ultracapacitors and on board generator.

11/18/2008 - Finally got it inspected and tagged so I am now Street Legal.

1/01/2009 - Happy New Year! Rewired the batt pack and added upgraded controller.
Should be back on the road by Jan 10, 2009.
