Open ReVolt was an open source controller made by Paul. It later I think morphed into what people call the P&S Controller, Paul & Sabrina, his wife.

A couple years ago he was moving house, and his entire moving trailer was stolen, with everything they had.

I think I've seen him pop his head in here once since, but I think even after he got his life back together he expressed he was interested in phasing out of the community.

The last time I looked at the files, someone mentioned "Oh yeah, there's some errors in them, that won't work..." and there was no like... update, or, repository or... anything to resolve that. You'd have to have heard by word of mouth and then had someone who had a more modern copy (who knows where they got it from) give them to you.

And support is obviously non-existant.

If you're set on a DC system, it's half a pipe dream, but for $50-$150 you can buy a scrapyard Prius Gen 2 inverter, and with some extra parts get a 500V 1000A controller out of it. Caveat: the documentation for it is currently even worse than the ReVolt, though, it has been tested at least twice (once by Damien, once by EV8, both who either designed it in their heads or didn't share the specific circuits). EV8 after some polite but persistent nagging, has said that probably after the Christmas season he will have enough time off from work to sit down and draw out what he actually built and share it with people. I've tried to impress on him that it would not be a wasted effort, that there are still people who would love to have a super cheap DC controller. You name perhaps can be added to this list.

That said, it's at best 50/50 whether anyone finishes anything they ever intend to, life happens.

If it's not time to buy your controller though, and you can wait a few months, perhaps give that a consideration too.

Having said that, I guess I will keep trying to build an Open ReVolt Controller from whatever information I could find.
Best of luck to you.

I got a pdf version of the schematic diagrams and a BOM. This is already a very good starting point. What is hurting me badly for now is that I don't have the PCBs layouts (control board and high power boards). But I will keep on trying to find them.
Umm, so I just went through my email. In 2018 I wrote to Paul and he sent me... I'll just quote it:

Here's some stuff for the AC controller (attached). Also, you can see the instructables here:
200kW AC Motor Controller for Electric Car

This is an alternate assembly approach that makes for a smaller controller:

The DC controller assembly is identical, but you just stick a DC board on instead of an AC board. You would use designSpark to look at the pcb and sch files.

... and then he attached 3 files. One of which is a .PCB file. I've never gone that deep into electronics fabrication/simulation. And... I'm not sure how to upload them. Will these forums let me attach non-graphic attachments?

tries that out

Are there 3 files attached at the end of this post? Are those useful to anyone?

I'm not sure I was supposed to share those publicly, but it was an open source project, which is now developmentally defunct, so, hopefully not stepping on any toes. Anyone who wants to educate me on appropriateness protocols, feel free to tell me what behavior is expected of me.

Whelp, I tired. Anyone have better ideas on where to host files? I expect anywhere I put them is just going to be net rotted sooner or later. I could play the dirty trick of renaming file extensions, but that's kludgey.

Hi Matt - if you can work out how to get those boards made then I would put in an order for Five !
No no no. I'm not making or ordering any. This was 3 years ago. I just dug up the files.

Can you attach the files to a PM??
No, and I was too lazy to create an other account on another website, but I used an annoymous temp file transfer site and PM'd Remy the files, so, perhaps he will host them on Mega or otherwise provide. Seems to have a better handle on it than I do, and, probably understand what's he's actually looking at.
