EV conversion budget analysis

 Before deciding on my options I've thought that it would be good to do some budget analysis.

EV converters may offer kits for around £20K (100 miles range). A small new EV can be cheaper, but then I would add another car to this already busy world, and considering the additional carbon emissions for the production of it. Converting an existing car would be recycling so that's my favourite option.
I hope to find a way to spend way less than 20K for my project.

For the time being I'll single out the most expensive items that are required, to see where there may be room for savings.

1. Battery
2. Motor
3. Adaptor plate
4. Controller
5. Charger

Let's not get too exited, there will be lots of hidden costs, maybe for small bits, but that adding all of them up will probably skew your budget of around 10-30%.

UPDATE ONE: I have been actually been able to buy the batteries I needed for £1,200. I'll update the chart below at some point END OF UPDATE.

UPDATE TWO: As the battery charger is taking a a bit too long I have now bought for £80 a Elcon 3.3 charger which I still need to figure out if I'll be able to get to work.

Caveat: The costs for bits and bobs including connectors and wires is not to included and is not easy to track.

As you can see the most expensive items are Battery and Motor. Adaptor plate let's say is a runner up.

In my situation I think I can save some money if I build myself the adaptor plate as I can do 3D design. I can get it machined from a CNC specialist company or do it myself at the Community Hack space where I usually go.

Battery I can just aim at a smaller pack in the end you wont be doing long distances on a classic Fiat 500, there wont be much space to put many modules. The first electric 500 from Giannini in the 1967 had 6 lead batteries.

Also the motor I could look around to get a decent motor but not something that will blow up the transmission or other mechanical component.

I'll update the budget thread as I go along.   

PS. If we look at salvaged motors and batteries we can certainly get to lower budgets. I suggest to look for abandoned projects on eBay regularly. I did find one of these at some point, but the motor size and the 8 battery size would have not fit on my small Fiat 500 car.

UPDATE OCTOBER 2022
I've started to see on salvage yards many electric cars. Example a VW ID3 rear electric motor drivertain drive unit for 1.5K.
The ID3 is quite recent car, so it shouldn't have too many miles on the clock either.
