Thanks. From €10k to €25k depending on what motor, controller and batteries you choose, plus what you pay for your donor car. Look up audia2ev on google groups most of my project is documented there.
That's an amazing achievement! I've seen lot's of conversions. Being an aluminium car, with an AC motor and a reduction gearbox instead of an ICE gearbox I really like yours! It would be great to have available a 2 speed "clutch less" reduction drive available, it would make EV's even better!
Thanks for the comment. Probably a two speed drive would be lots of complication for little gain. On a sports car maybe, city car not really worthwhile I think.
Newbie question though, as I'm planning a similar project on a 2002 Fiat Punto:
Wouldn't using the car's original gearbox setup help reduce power consumption? As in, use the gear ratios to reduce the motor's RPM, thus reducing the power requirements? Since an electric motor's maximum torque is available at 0 RPM, that should be possible, no?
Thanks for the compliments. On the gearbox Q's: "reduce power consumption" - no, because the gearbox reduces efficiency. "reduce motor RPM", yes, but this doesn't reduce power requirements, what it does is usually increase your top speed; "max torque at 0RPM", you said it, torque, not power, so indeed you can start in a highish gear but the power curve is not like the torque curve. I designed for good perf in the 0 - 90 kph range, indeed if I wanted to go faster a different gear would help.
cont... gearbox in my opinion = less efficiency (=less range), more slack in drive system (not good for regen), heavier car (=less range) increased chance of mechanical failure (petrol gearbox not designed for this degree of torque) and my expectation is only two gears at max get used, probably 3 and 5. I know a guy who did it with a A2 and original gearbox, to get to 120kph, I'll ask him.
It looks very good! Do you think there is any need for a suspension upgrade? atm it looks like it is fully loaded and hangs a bit in the back. I hope you have success with getting the power steering working. Or you can search for a manual steering rack if that will not work.
Thanks. Suspension upgrade - no, total mass is very close to original (didn't weigh it yet though). Yes it is low at the back, but in fact the weight = two adults (175kg). What I need to do is move batts forward, front is maybe 150kg light compared to original. Power steering will be hacked, one day... not sure there was ever a manual version. It's OK to drive at the moment, just feels a bit retro...
There are manual versions of the "real" 3L versions Euro3-D4 with 81g/km CO2. If you can't hack the ps in the future. I am excited to see the final layout when the car is finalized.
Nothing too technical I am a civil servant with a technical/science background, but in terms of this project what was useful? DIY skills, some basic electrics (like, rewiring the house), and knowing a few people who know how to weld, etc.
Thinking this over - I shouldn't under state it too much. OK I have fixed a few cars, a long time a go, and I have an advanced University degree - so I think I can solve problems. But in fact what has been done here is not out of reach of a DIY mechanic. What is difficult is finding the solution each time to a new problem. I should add I've had half a dozen friends to quiz and lend a hand, and the whole internet to ask questions, get advice and see how others have done things.
should be 105kph (this was a choice), I've been to 90 so far. Range: did almost 100km on first full charge, but it is hilly round here, I guess 150km on the flat at medium speeds. Charge time: 9hrs/overnight. 0-60mph: should be 15 secs or so, at the moment it feels like it pulls away really well up to 70kph. The design was to get best performance from 20 to 70kph - that's the real driving speeds for the intended use.
Yes but not necessarily more acceleration. I'd say it is like the original 1.4, but my design was to get best response up to 70kph. I guess you might race the petrol one more easily. Remember the petrol is 55kW at peak, this one is 40kW (but a flatter power curve and loads more torque).

Well done on such a great project!
Can i ask how much it would cost to do a conversion?
I love A2's so much i am currently looking for my second one (I owned one a few years ago) :)

Well we have almost no hills in holland.. all flat everywhere =) so that's no problem here.. good luck!

What is your planned average range you have calculated?? Or did you already drove the full range out of that audi a2 ??
Anyway ... audi a2 is one of my favorite cars.. And i also like electric cars.
( but i dont see potention in electric cars for the next 20 years... maybe later )
I more like efficient engines with lightweight smart cars. It's nice done but still future talk...
Great project !!! =)

It is around 100km, I have driven 120 but that is too far... when your batteries fade going up hill it is a bit of a difficult experience...

Have you solved the problem with the CAN bus??
I would like some more videos from the outside...

Power steering, and move batteries to final positions under the car are the two biggest things.

nice.
what is the acceleration like?
my a2 1.4 does 0-100 kph in about 11 seconds, the ev should have much more torque.
