No pistons, no fuel, no worries! Toyota Sera EV Conversion begins…

That would be bloody awesome!

I dunno how the motor / batteries would hack it...
Would need to keep a close eye on brush temps n stuff..

You gotta stick it on the dyno too. We want ruler flat torque curves.

[TC1600]

I would expect it to look something like this:



Top is power, bottom is torque (electric motors produce max torque at 0rpm).

That's about what I would expect, nice work on the dyno graph !

It was quite odd to see that Prius on the dyno.
A pure electric car will produce a different dyno sheet though i think.
Remember that the Prius also has the petrol engine and some funky transmission stuff working too.

TC1600, can you do me a favour though and host that photo on imageshack?
I dont think my employer would be too happy about hosting that image for you

where the fat cables bolt onto the Zilla controller- you might want to paint them with rubber insulation shit or put some heatshrink over them - mostly to stop the bolts loosening off.

Done, sorry, I got it off another forum, so wasn't aware it would be a problem. Link is here:http://priuschat.com/forums/gen-ii-p...is-dyno-3.html. Not sure about the power graph, but I would expect the torque curve to be somewhere around the mark.

VA61DETT: Nah, I work at Ultra Tune lol, see reply above.

Heh, funny how things move around the internet.
I took that photo of the dyno screen, gave it to my boss in the USA (he owns a Prius), he must have shared it with someone, and its moved on from there.

I do, yes
Kinda strange you know about the company since we dont really sell in Aus.
You use our displays/software?

[VA61DETT]

Aah cool

I have loads of other electronics projects, many including small character LCD's
I used to use the crystalfontz software on my net server @ home for displaying random cool stuff... yannow just cus'

I have long term plans to build a custom dash for my VA61 which will include a nice 40 X 2 display for odometer / trip computer stuff.
Have spent loads of time eyeing off suitable LCD's / VFD's

So your using CrystalControl2 then?
Thats my software

Send me a PM... might be able to send something you way

Loving the work so far, quality is right up there.

Question, where do you get the terminals for teh massif cable and how do you crimp them? I have some 0 gauge battery cable and it's very hard to find suitable terminals for them - maybe I'm not looking in the right place because I've never even seen 0000 cable before. It's also hard finding isolation posts.

I bought a hydraulic crimp tool of a Local EV parts distributor (zeva.com.au, now evworks.com.au I believe), it goes up to 70mm^2 cable.
He also supplied some of the large terminals, you can also source them from welding supply places and electrical distributors.
I got my big ones from www.evsource.com
I scored all the monster cable from my local scrap metal yard, they get some massive stuff in from time to time, I have seen more then 4 times that thickness!!, bloody crazy big industrial stuff from underground mining equipment.
Get it for whatever the going copper rate is...

[Scuzzy]

Very cool project! I was given the link to your thread by Terra Operative and I've since passed the link around to a few other Sera owners who think its great too.

[VA61DETT]

Cheerz,

Got the next 4 days off, if all goes well I rekon she'll be ready for a test drive by Monday!!!
Can't wait
