hi everyone, i am building a ev vw beetle and i need a controller but i have a some questions, i will buy this controller

http://es.aliexpress.com/item/1205M-5601/32701184384.html?spm=2114.13010308.0.62.F1YFYu

and i need to know if is posible to program whit this cable ?

http://www.ebay.com/itm/USB-programmer-cable-for-Curtis-controller-/152188098489?hash=item236f1e17b9:g[tongue]-AAAOxyaTxTPxdO&vxp=mtr

the software to program the curtis controller only is compatible whit win7  ? someone have the link to the new software to use whit that cable ?

thanks for readme :roll:

If it was me I would always try and use a controller that has free, or at least cheap to obtain configuration software.

I would not buy a Curtis controller knowing what I know now, but is that one in the photo genuine?
Anyway that would not be sufficient to drive a VW Beetle

What sort of motor are you using? That controller is for a DC motor, which again has disadvantages compared to brushless motors

i have a 9kw motor,  you have some experience whit a curtis clone ?

why you said than is not enough to drive a beetle ? is a 500amps 48v  [smile]
what controller you recommend to install to a beetle

These 500amp (peak) controllers can do about 25% of that continuous, and that's if you have a genuine one. That controller may just power an electric motorbike

What model of motor is it, can you post a photo / or specify which one it is?

well i have a 9kw dc series motor, i dont have the brand but i testes whit the beetle and can move the car [smile]

you tested that controller ? the copy of curtis are bad ?

thanks [smile]

I don't know that model, so I guess you would have to try it and see, but I would not be hopeful.

I dont want to be negative but there is a huge difference between "moving a car" and even driving at 30mph for any length of time.

What batteries were you thinking of using?

i will use a deep cicle 12v 150amps i will test whit 3 of them
how much amps in batteries i need ?

Hi Daveisnt.
  Could you share the wiring details for Arduino board please.
Much appreciated.

When I first read this post, I ignored it and went with one that suggested connecting directly to the DB9 serial port in my laptop.  I did this mainly because it was a heck of a lot easier -- it didn't work though.  Lesson learned.

In the end I was successful by using an Arduino UNO R3 board as the USB-TTL converter and a 4001 IC (2 XOR gates) to invert the in/outs.

If anybody's interested in the wiring details for the Arduino/4001 solution, let me know.

Dave

Thank you all for the rs232 circuit cable and program.
all worked very well and helped me fix my mothers mobility scooter.

Once again many thanks.

It seems the username and password do not work now at the Curtis site for the latest version...  If there is someone able to get on and download it here, and do the file extension swap, that would be great.  I would think from reading the posts, that the docs (.txt) file would be needed too.  Thanks in advance.

worked when I just tried it
Maybe copy and paste the username and password in because there are zeros and letter O's that look similar

Looking for some help. I bought a 2008 Zenn electric car with a Curtis 1236 controller. I also bought a Curtis 1313 handheld programmer. I've been trying to change the parameters in the controller to increase the top speed but have been unable to successfully do it. Any suggestions out there? Thanks

Cmg505, is it that you can't change the parameters, or that changes don't make any difference?

As a note, I don't think changes would make much difference on a Zenn, because ultimately it will have a low top speed regardless, limited mostly by the batteries.
Also sometimes best to leave well alone if its working, because I've had bad experiences with adjusting Curtis controller settings on an Aixam mega, which I believe is  a similar vehicle.

I was given this car without any documentation or operating history. It has a Curtis controller 72V, and it does not run. I have cobbled up some used batteries in order to get it running prior to shelling out for new.

I have a manual for a similar controller and am trying to figure out a testing game plan and could use some guidance.

All the wiring appears sound and I have not located any loose or stray wiring.
I turn on the key switch and get power 72V on pin J1-1.
No visible flashing LED.
Main contractor does not close when the throttle pot is depressed.

Hey that looks cool. Never seen one like that, what make is it?

I try to avoid Curtis controllers, and SEPEX, so you have a double whammy of problems there!

Was it registered electric at build, or is it a conversion?

I'd be tempted to jack up front wheels and put 12v on both circuits and see if wheels turn, because one battery is enough to give the outer windings a magnetic field (F1-F2 leads) so one battery would do that, maybe connect two to the inner circuit (B+ B- leads) if one doesn't turn it

Also does it have an auxiliary battery on it to power the car lights etc. Can you see a 72v to 12v converter anywhere, because its that which drains the main batteries.

And main contactor should not close on throttle, it should already be closed, as that happens at keyturn

If you want to check some controller voltages, test between j2-6 and j2-4 (the smaller block of 6 which goes to the speed sensor) see if you get about 15v, and also j1-13 and j1-14 which goes to the throttle pot (from memory that's only 5v)

The car is an IT and was manufactured in British Colombia some time ago. From there it went to Pakistan where apparently they are still in production according to their website, although they do not reply to emails. I'm in Seattle where they have an active EV association. http://www.seattleeva.org. I reached out to them and did not get much traction, http://www.itiselectric.com.

The car has an auxiliary battery for 12V which operate the lights, heater, etc. and is totally independent from the power bank. It has it's own AC/DC charger.

The car is on jacks because I don't want the car to suddenly take off and wipe out my knee caps. I did think of by passing the controller as you suggested but started to over think it. I will make up some leads and do that soon and hopefully you done see the big flash from the UK.

Thanks for the instantaneous response. I'll keep sharing my findings.

Karl

Yes keep us informed, I'm pretty sure the wheels will turn, but I have to say that the SEPEX design is not a great one (it uses some of the power to create the field, as apposed to perm magnets) , and it is a brushed motor, so the performance and efficiencies of those are not great even when new.
Still the car looks nice, just don't spend too much on it as those type can be more expense to get running than say getting a newer Lithium brushless small car

Does anyone have a download link for update files of the 1313 programmer (with any required login info too please).

Like this info:

The 1313 is the handheld programmer isnt it, does that require updates?
The password still works for the 1314 software download
