Drill Bike - Kawasaki 550 converted to DeWalt 36 Volt and PMG motor

Home page for Drill Bike
Converted this barn find 550 in 2009 - 2000+ miles on it so far. Added 4 more batteries in 2011 for extended range and a little more kick. Bike is a blast - slow off the line but kicks but between 25 and 45 mph (direct drive - no clutch, no gears). Only 230 lbs. Tricky paralleling the DeWalts but once balanced they stay balanced. The A123 batteries are a best kept secret - you can discharge them 100% and they charge up and ask for more. Over 200 charge cycles to 80-100% and they are still full capacity - no sag in range or voltage. Not much warning when they run out, though - you are blasting merrily along and then... nothing. Check out the discharge curves on the home page.

Think Green

Changing our world one kilometer (or mile) at a time.

After people tell me,

"You can't do that for next to no money, made from a recycled
car, recycled batteries, recycled wires and recycled dreams."

It kind makes it hard to just let it go, knowing how easy this converting process is. A couple weeks ago deer hit me on the way to work and destroyed our car, we were going to replace the car with another "beater" as a commuter car but thought this would be a perfect time to realize our dream and convert a car from gas to electric. We started looking more intently for a car which would make a ideal donor car and found Brian.

Below is a picture and video of Brian Sauve the person who donated our first donor car, Brian dream originally was to convert this same car to electric but time does run away. Here he had just drove the car onto the car trailer for us (Uhaul rocks). It was a sad moment for Brian but he was very happy that his car will have the second life in the manner he dreamed of. When this conversion is operational Brian will one of the first and few to drive this reincarnated "Lean Mean Clean machine"

The car now in our drive way after searching for this model and year for over a year and a half now safely in our drive way. The planning and time lines start, six weeks the goal to have the car "operational" may be harder to adhere to as working on the car out side with no garage dancing with mother nature (she always wants to lead). The full range target to work and back is 150 kilometers (93.21 miles), down hill to work and uphill back its like a 12 hour roller coaster, 12 hour slow roller coaster.

Plugging in at work would not only reduce my need for full range from 150 km (93.21 miles) to 100 km (62.14 miles) it would also lighten the vehicle thus placing less stress on bearing, joints, suspension and other mechanical items.

Lightening the car would also allow it to maintain what little cargo space is has and allow "a passenger" other that bobble heads.

Adding solar panels on the roof unfortunately will not add much generating capacity (except maybe to charge the 12 volt operating system. You need a lot of amps to charge batteries and a couple of 100 watt solar panels only generate about 16 amps, I think the car would have to be parked in the sun for about 3 days straight to charge the batteries up to full, but I still learning this whole amps, volt and watts language. But I think a couple of peel and stick solar panels as racing strips up the hood, across the roof and down the tails might be a nice touch.

It does make the mind, body and spirit work harder, to improve and prove that dreamers are the ones most planted firmly, success is in my dreams and reality. Only you have the right to deflate your dreams.Brian Sauve_0.jpg

EV Karma - 1971 Karmann Ghia

I recently had an opportunity to buy an electric car. Pictures follow. The car is a beautifully restored 1971 Karmann Ghia and the story goes that the restorer, upon finishing the restoration, decided to make it electric rather than put in a gas engine. The electric system isn't the best so I plan to redo the conversion over time.

As it stands -- it has a D&D ES-15A motor running at 72 volts. This is a Brushed DC series wound motor. Alltrax controller and a 72 volt pack of huge flooded lead acid batteries.

Performance is weak and range is short. It does make it to 45 miles per hour but takes awhile to get there. Haven't done a proper range test but an 8 mile ride yesterday tells me that 10 miles is plausible. That should be enough to take me to work where there is EV charging stations available.

The conversion is very well laid out - just using ancient technology batteries. My plan idea is to get a 120+ volt LiFePO4 pack and switch to a higher voltage controller and keep the same motor.
