72v 1500W 40A Hua Tong CA08 XM06AD_P04.1 controller

[cohberg]

Just got this controller working

mauimart, please could you tell us what the green plug and extra red plug do? We were guessing 3 speed switch and regen/abs

[PeeHell]

I think we sould start a new thread about "greentime controller" if it hasn't been done yet...

[jk1]

I notice auraslip said he modded the LVC down on these hua tong controllers but i can't for the life of me find the details of how it was done ! was it this thread or another huatong thread as i have seen several threads recently on these controllers

I put "hua tong auraslip" in the search box and this is what came up. Hua Tong is 2 words, like John Smith. I too find this search engine very lame and spend hours trying to find things.

Okay, so I just received the Greentime controller, and I must say am very impressed (although it took like 40 days). The jittery behaviour I felt from starts and at certain throttle ranges with the hua tong are non existant with this controller, very deliberate. The current seems a lot higher, but I don't have a wattmeter to give an exact figure, they say 45 or 50A, depending where you look, I suspect it's closer to the 50 range.

What was extremely interesting to me is the connections used for regen braking, If you look at my earlier post, with my Hua Tong, I used X and got reverse current, albeit for a short moment until the phase wires were shorted out, which told me that it was capable of regen, although I couldn't figure it out. On this Greentime, the regen is activated by connecting DS and X. I am super busy with midterms and such, so I won't have the chance to try this out on my Hua Tong (x may have to be connected to something other than DS), but if any of you folks want regen(very redundant), my suggestion would be to try connecting x to something other than GND, I would bet money that this is the ticket. It is activated when a brake signal is present.

Good luck, hopefully someone else will carry on the regen flame and finish the race for everyone still using a Hua Tong!

[cohberg]

sd as in the throttle input?

[stewrobb]

Thanks, I made a mistake with the connections, they have been fixed

I spoke to the seller, and he actually gave me a list of all the pads and what they do. Great guy. I have put them on my picasa as well. The seller clarified "K1 K2 dial gear", you connect them together to advance timing for a slight speed boost. This is seriously the best china controller I have ever used, It has all the function you see in the image, plus 3 speed, and cruise. Everything is as it should be, regen is powerful yet smooth (running on 72v SLA's). The MOSFETS are 4410's rated to 100v. The seller was absolutely wonderful, and answered all of my questions within minutes. Shipping took a long time, but it was because it was held up at customs, so I guess I got unlucky. For $50, it is 100% the best bang for you buck.

[wesnewell]

It's great that you like your greentime controller, but why is it in this thread? For this controller, X connected to ground IS rengen braking. Posting info on your conbtroller in this thread just confuses things. Please start you own thread to discuss your controller.

[stewrobb]

well because I have previous history with my other Hua Tong posts, didn't realize it had been split up. people were awaiting my response here. fair enough. So what I am wondering is are all Hua Tong's without regen after a certain date, or do some sellers on dhgate sell this one, and if so who? thanks,

There's at least 3 different models being sold as a 72v 1500W 40A Hua Tong OT100 controller. I have 2 of the original ones per subject line. I'm not sure as to the status of the other 2. I would suspect that they all support regen braking and it's just a matter of finding out how to enable it in the controller.. I've read it's not with the X pad on the one with the 4710 fets. Regen braking will not work on any of the stock ones if you use higher than standard voltage battery packs. It won't work with fully charged 20s lipo. It does with 18s. LVC is about 60V on this controller, so 18s works out perfectly for both regen and pack protection.

[stewrobb]

Good to know, I wonder if the same sellers have different models. Isn't the regen voltage proportional to the lvc? I am about to start running my 20s packs that I am building and require regen (broken rear drum brake). I hope this will be adjustable. Thanks

At risk of being yelled at by wesnewell, I just got the new board and the new plugs are reverse (black green) and three speed switch (brown black red).

No yelling, but you should open it up and document what you have, board number, caps, fets, etc. if it's a different board, then you should start a new thread with it's number in the subject. I haven't seen one with the 3 speed switch and reverse connector coming out. I'm sure if you document where the wires go from those connectors, it will help someone. Would really be nice if it has this pcb in it.

I read this thread and ordered this controller, but it arrived with extra wires than what is described in page 5 post. I tried to wire it up and it does not work. The throttle position wire I believe may be backwards or something else needs to be plugged in? I have 5 wire hall sensor plug, 3 wires to motor, and 3 wire white colored plug to thumb throttle, and ignition RED wire connected to positive on battery. Is there anything else needed to be connected to operate controller? ...what do the other red plugs do?

I checked the controller with this http://www.ebay.com/itm/NEW-Portable-E-bike-Brushless-Motor-Controller-Tester-/250919544203?_trksid=p4340.m185&_trkparms=algo%3DSIC.NPJS%26its%3DI%26itu%3DUA%26otn%3D5%26pmod%3D250905322582%26ps%3D63%26clkid%3D4078499369340164742#ht_3904wt_1185 and it doesn't respond to thumb throttle. I bought a new controller because old one would overheat and stop driving the hub motor properly, losing power and studdering until it would not work.

[cohberg]

edit: the throttle is a white plug. did you mix it up with the 3 speed (red plug | brown, black, red)?

I believe that the throttle is wired up like regular. Green is sense, black is GND and red is +5V. Also something that might help is to pull the controller apart and look for the status LED. It'll tell you via blink code what the problems (if any) there are.

I don't really know what specific fuctions your tester has, but if anything i don't think you would testing your controller. You should be testing your throttle/hall/phase to see if it is functioning normally. Not the other way around.
Maybe i'm just understanding you wrong but the way i test is i get a 10K pot and just use that as my simulated throttle, less variables I guess.

what do the other red plugs do?

As to the other red wires the 4 (3 populated) pin is alarm the 2 pin is pack voltage and the 3 pin is speed switch.
iovaykind labeled it all minus the new plugs

[bobale]

On mine HuaTong throttle connector was wired up wrong way, so I had to swap black and red to get it working.

here is my controller

ebike controller.jpg (153.17 KiB) Viewed 774 times

i tried to switch red and black wires on throttle controller 3-pin connector. I cannot get the motor to spin...any other ideas? I am only using 48-60 volts currently, does that matter on this 72V controller? I have 12s or 14s lipo configuration.

I am plugging in:

5 pin sensor motor wires
3 pin thumb throttle
3 phase wires to motor
2 pin voltmeter
1 bare red wire thought to be "ignition" or torn ON switch tied to battery positive
2 ring terminals red/black to battery plug (now deans connector)

not sure why its not working...

thanks for reviewing and any ideas...next idea is to disassemble and review wires on circuit board. but i still don't have a diagram showing what goes where yet.

edit - right side of photo yellow block should say "3wire to thumb throttle"

[cohberg]

If you're using 12s or even 14s i believe that you're hitting LVC.

8 blinks in a row is lvc.

It be helpful if you listed what you have (motor, throttle, etc)

[kentlim26]

You need at least 16cells or 18cells. volts supply must be above 75v to see motor runs smoothly. when the battery volts is supply 60v or 62v will power off - with this 72v controller. since this controller can accept 80v, it will be definitely alot of interesting and FUN !!

It won't work on anything less than 15s lipo (63V). I'd consider 18-20s optimum and 24s the max. I run a 10ah 18s pack and a 5ah 24s pack.

Mine cutted off slightly below 63 volt before changed the lvc resistor to 2k, now the cutoff comes in about 36V.

[kentlim26]

which is the resistor is the LVC , i will like know. how how to change them ? kindly show some photos so, i will really like to try it out. i think is really good for us, everyone will like to try out lower voltage 48v pack.

thanks !

Changed the resistor A from 1.2k to 2k, the first link has the pictures and from there the third photo has the marks for A and B.
Remove the smd resistor(1201) and replace it with standard thread or film resistor.
I've tested the controller on table with adjustable voltage supply and tomorrow it'll go to my e-scooter(48V or 60V, haven't decided yet).
