Paul & Sabrina's cheap DIY 144v motor controller

[amazuki]

Hi
Finally made it to the last post. but nobody is posting since May. Is it Off already?

[amazuki]

btw i am from Malaysia and trying to build an EV.

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.

I see, oh dear does that mean another 300+ page to crawl? I can never finish my EV.

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.

hi ian
how much is the cost of the components and how much to ship to Malaysia?

[amazuki]

my ev is still without an electronic controller and I dont think I can afford a curtis

Hi Amazuki
I can't send you a PM yet as my post count is not high enough.

Hi Amazuki
You can contact me via the web site Australian COUGAR 144V Motor Controller Kits.
Sorry if this is a bit of track, people.

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
