New Open Source E-Bike/E-vehicle calculator & simulator

[dodjob]

I will be one of the thankfull waiters thanks for your work!

I've downloaded the zip file to my puter a few times, but when I try to open it up, Windows 7 sez "Windows cannot open the folder. The compressed (zipped) Folder xxxxx is invalid."

Is it something on my end? I appear to be able to open other zip files - was this maybe corrupted by the upgrade that toasted the pictures?

I get an error as well in Window 7. I am using Winzip to extract. I get a "start of central directory could not be found; Zip file corrupt. Possible cause; file transfer error."

I tried it 3 different times on 2 different PCs. I also tried it to a Windows server and it couldn't open it either.

Taz - I've uploaded it on my site - it's a fresh compression so it should work https://sites.google.com/site/shelbyele ... /tech-docs

Does anyone have any ideas on how I could use this to model using two hub motors at once?

[GCinDC]

Can you help me?

I just tried to download the versions posted here and found them to be corrupted too. Best thing I can come up with short of getting Netbeans and building it is going to http://www.assembla.com/code/ebikecalcu ... des/EvCalc and get the zip there. Or you could look at the previous revisions to get an older one. Hopefully only a correctly built file was committed. Thats what I am trying anyhow. -Damcard

Any instructions on how to install/run this simulator? I can't unzip the original and don't know what to do w/ the files listed at the site above. Thanks.

Yeah I think that download is corrupt...

Bumping this to find out if there is an update available anywhere or a working version?

[Skippic]

That one seems dead a long time.

Justin's simulator is now much better than before:

Sure is, but you can't input custom motors to simulate so it doesn't work for me.

Hello all! I thought there was a working zip somewhere earlier in this thread, but if it's not working anymore, I'll upload one later on today. Thanks for bringing it to my attention! I want you guys to get your awesome e-bikes rolling as soon as possible and spread word of THE REVOLUTION!

[nieles]

[itchynackers]

Is this version newer than my July 2010 version?

[Doctorbass]

thanks swbluto

I still have my version.

Is there a way to add by ourself the new motor and parameters ?

Is this calculator useful for C80-100 Turnigy's with stock windings? The resistance of the 80-100 is listed at 3.2 mega ohms, but that doesn't compute with this calculator... What settings should I use, if any?

It's actually 3.2 milliohms.

Here's version 18. I've added a readme and thanks to ebikes.ca for their permission to use some of their formulas and parameters. Their simulator is pretty awesome!

Stock C80100 with 130 RPM/V has about 32 mΩ phase-phase, not 3.2mΩ...

Sounds about right. I assumed the HobbyCity worker accidentally used the wrong prefix, but it looks like his digits were off too.
