2001 Electric Polo EV
Our Polo EV has gone to a new home.



The full build thread is here. Polo EV Conversion

We are now contemplating a second Volt to keep the first one company.

My wife doesn't want another SUV & a Tesla S is not in the budget this time around.
(need to sell the kids first)
The Volt that we drove was very quiet & no whining noise that I noticed.

Sorry, I didn't mention the voltage. I was assuming a DC motor at 144V nominal. Looks like you're going down the more efficient AC route. Don't under estimate the big hill. I know it is only a short part of the trip but it is steep with no let up from the bottom to the top. You then straight away ha...

I converted a VW Polo last year, I drive it every day & now have about 18000 electric km clocked up so from my experience, here are a few things to think about. To get the range you want you will need 210Ah Lithium cells at the very least & you will be working them pretty hard. Even bigger would be ...

Update to this. The RTA in NSW have brought forward the online processing date deadline for the Engineering Signatory System (ECS)to August 22nd 2011. From Monday, the RTA are apparently not accepting engineering reports via their online system. Not sure what difference this makes to Engineering Rep...

I had a good look at these but decided it was too fiddly for a car. TX valves only work in one direction so you would either have to have a second one installed going in the other direction close to the outside condenser. You will also possibly need 2 bypass valves across each TX valve to bypass the...

My engineering signatory has told me that as of September 30 2011, the current Engineering Signatory System (ECS) will cease & so will the engineering certificates. It is being replaced with a new Vehicle Safety and Compliance Certification Scheme (VSCCS)however there are no details about it at the ...

Solid state relays are a great way to go. They do need heat sinks if you want to switch more than about 5-10A continuous. A couple of electronics guys I know also recommend flyback diodes on the control side of them just in case there are voltage spikes from relay coils & the like elsewhere in the c...

This circuit as is shown using the Jaycar SY-4050 relays is potentially dangerous & will fail the NCOP14 Checklist Clause 4.3. The components suggested are not rated for high DC voltage use. These relays are rated for 30VDC 10A max only. They are not safe to use to switch HAZV traction pack voltages...

There is some other stuff called Alminox Electrical Joint Compound & is made by Dulmison. It is what the energy authorities use on their high volatge connections. It is recommended for all aluminium to aluminium or aluminium to cpper connections. I don't know where to get it though. I got some throu...

All too true, LightningEV, all too true.

Hi Peter
I can probably help you.
Need to talk about what you want to do first.
You can contact me via my web site link below.

If you are going to use a solid shaft between the two motors, you will need to accurately machine the fabricated motor mount so both motors are absolutely dead in line, both axially & radially. No matter how good the welder is or how tight the jigs are, ALL metal moves & shrinks when it is welded. I...

Have a close look at your helmet. You will probably find a couple of button cells that can be replaced. My helmet (a 3M SpeedGlas) started doing the same thing. Would not darken when welding but would darken out in the sun. Leaving it in the sun made it work properly for a little while. Replaced the...

For small amounts both Paypal or bank issued credit cards will take about a 3% commission on the conversion.
No one ever gets the dollar rate as shown on the currency market rates. There are always commissions or conversion charges somewhere.

Be easy enough to fabricate something like that in steel & machine it so all the faces are true, etc, etc.

I can make almost anything in steel in almost any shape you want.
All I would need is a drawing of what you want.
PM me if you are interested.

I have come across a couple of examples of people using alternators for regenerative braking & I am considering doing it myself. One person had rewired the alternator to output 160V & it fed juice into the battery back. Another person simply used a standard alternator to feed juice into the aux batt...

My bulk buy supplier requires the same thing. A failed cell would need to be shipped back for testing but given the high QA of LiFePo cells these days, a manufacturing failure would seem to be very rare indeed. The point I was trying to make was there is no difference, warranty wise, between a priva...

Just read that Ontario require any EV conversions to have one of these stickers on the front & back windscreens to alert emergency services that the vehicle is an electric conversion. http://forums.aeva.asn.au/uploads/1105/evc-2in.jpg Although we don't have very many EVs yet, the numbers are slowly ...

Warranty. It has been mentioned by a certain vendor that batteries purchased in a bulk buy arrangement have no warranty. That is just not the case. The manufacturers and/or vendors offer a 12 month (sometimes more) workmanship & materials quality guarantee. I did some checking on some US lithium bat...

I am not a loss-leader/non-profit vendor nor do I have any commercial interest in importing batteries for EVs at all. I am a private individual who is in the final stages of building a EV. I have organised this one-off bulk buy of CALB batteries for my own purposes & am happy to include anyone else ...

Closed

This buy has now been finalized.
