I think that this thread has sort of broke out into new threads of the various individual controllers people have built.

It is a bit of a bear to read this entire thread. Congratulations on doing that!

Also, there is an AC controller in the works now as well, and I think a lot of people's interest is focusing on that at the moment.

Hi Paul, Sawickm, Louman & others.
I put together the Australian Rev D kits & make the machined cases.
Much credit goes to MCUDOGS who designed & organised the boards.
You are right about shipping to the US. Very expensive because of the weight.
There is very little written about the Rev D version yet because there are simply not very many yet.
MCUDOGS has one finished & in a car but he is still working on the rest of the car.
I have finished one. It is all tested & runs an Impulse9 on the bench but is not in a car yet.
Another two are in the final stages on completion & could be in cars within a month & there are two more about to begin construction.
Once a couple get on the road, there will be something to write to the forums about.

Hey Everyone,
I don't have the logic side done as yet, i'm waiting on the next incarnation that will include CAN, but i've got a need to order some parts for my ebike from Digikey, and I figgured I may as well order the powerside capacitors at the same time.

I need some help with Capacitor selection. I've got 4x Powerex CM400DU-12F Modules which i'm going to be using for the build. I have a target voltage of 288v+, which will require 400v+ caps.

adamj12b has said he's using Panasonic TS-ED caps. 6 for each IGBT, 560uF each 400V.
(The Australian Electric Vehicle Asn: IGBT Group buy for open source controllers)

But before I purchase the same caps, I'd like to understand how we select apropriate capacitors. The Soliton1 advertises that it has: "Cutting edge capacitor: State of the art ultra low loss 600V film capacitor. No electrolytics to dry out and fail!"

What kind of film capacitor would they be talking about - I checked wikipedia, and there is a plethora of film caps.

I asked on AEVA what properties I should look for in higher voltage caps, and MCUDogs gave the response: "It's the cap properties, ESR, ripple current and temperature. "

Now i'm asking why these properties?

I'm assuming we want a cap that will operate in high temp environments.


on a side note, I'm going to look at a donor car tonight... oh the excitement (1992 Toyota MR2)!

Thanks,
Haydon
