This was my request
Thnx a lot
Just awesome thanks again for sharing, I just have to dismantle the motor controller on my sons go kart we built to get some brakes at last 😃👍👍
Subscribed too 👌
Finally I found this regeneration brake 😃👍
Thank you your very helpful 😊
Have you seen the controllers that are 'fly by wire' ? I've just repaired an e-scooter, but thought I'd get a similar new controller to do the repair (didn't want to wait a month for ali express). After swapping the wiring to match the old controller, and changing the braking from low brake to high brake, everything seemed to work - Apart from the accelerator! The old display (a tf-500) was able to get the data from the different controller (a tf-100) to display on the screen (manually spinning the motor would show the speed), but the accelerator command wasn't recognised. A right pain. Neither controller had an analogue accelerator input, but it looks like there is space on the board to add one (4.3v, ds and gnd), and I guess it would work.
For these two controllers, everything is done through the tx and rx leads, the hall sensor for the accelerator is built into the display, and has no analogue output. It was interesting to note there were no error codes on the display, even though the accelerator didn't work. I also found that the newer controller had a brown and blue wire, brown to one of the phases and blue to a pad labelled A3, linking the wires made the motor electrically brake if you tried to roll it (I guess the wires were for an anti-theft device).
In the end I used a mosfet from the new controller to repair the old one (a bit of a waste tbh), and I had to transfer the wiring over again! At least I learned that a controller for a kugoo m4 pro is _not_ a suitable replacement for a damaged one from a bogist m5 pro - even if you re-wire it to match, and even though the scooters both look similar, and even if the circuit boards are identical (must be different firmware).
The EBS function looks savage! On my 500w 48VDC bike I reckon I'd be thrown over the handlebars if I pulled on the brakes with the EBS enabled. No wonder the EBS was disconnected at the factory!!
EBS - Empty Bowels System for front wheel drive, or for back wheel drive, Extra Big Skidmark. 🤣
My controller looks the same on the outside but the insude is different. On mine you simply short the X and DS pins to activate braking when you connect the usual brake wires. Also on mine A1 cycles through the speeds and F1, F2, and F3 are the speed indicator lights to tell you if you are on low, medium, or high speed when an LED is connected between each one and ground
Thank you very much, managed to find my EBS and cruise control pads following your instructions.
EBS = FD
Cruise =XH
I had a pad labelled EBS that measures 5v with ground, but it doesn't do anything when grounded
Bravo mate!
Thanks so much for sharing this AhmadYusuf85, you are the man!
looks like there might've been a cable there during production that got yanked out before it got sent out of the factory.
I use a lot of these esc's so this will come in handy, cheers!
Hmm perhaps the regen current spiked every other time and blew a bunch of units so QC yanked it?
Hello, I had a little question about the video, what is the brand and model of the driver card you are using and can we do this for each driver card?
I have build two ebikes for over a year with plans to use ebrake instead of disc brake.
I search everywhere but could not find Solution to Ebrake.
Here i am, Celebrating this great find.
To add to your finding.
I noticed that most Chinese Controller have alarm connector.
One of the wire is connect to the Pin.
No need opening the controller and soldering any wire.
Thanks again @EV-Customs.
Do you mean that connecting the ebrake to the alarm connector will make it work the same way?
@@Vea800 one of the wires in the alarm connector is where the ebrake can be connected to.
You should first test each of the wires while throttling to identify the right wire..
Hope this helps.
Does it mean that i can connect wire from alarm to that pin and I should have wheal lock when alarm goes off ? My controler oryginalny dont have alarm plug but it have electric brake , but the pin A3 is not connected to anything
The alarm wire is just like a ebs 100%
It would make you fly over the Handel bars, but not gonna recharge anything
Instead you need to find the correct pad that when the brake levers are engaged they regen for you
@@kamillapaj87 if your controller have ebrake originally, then you are lucky. 😀

I bought one of these and A3 is connected on blue/white line it is labeled as security signal. Based on reverse engineering it will short out all the three phase wires thats why it somehow acts like a brake.
Bro...which point to get line for ignition switch? I can't start up my controller. Thanks
hello, thanks for this video, I wanted to ask you something, if I wanted to dose the braking can I connect a potentiometer? I don't want to skid on asphalt.
That's not so strong to lock your wheels
You could if using a thumb throttle
hello, is it always on A3 pin?
the green wire, the pulse signal output wire, can you explain more of that. I know it is used to see the speed. But what is the output? how do we read the value through an Ardiuno?
Does EBS automatically cut off power to the motor aswell?
Hi,please help me,i want to add a 3 speed feature to e bike but i don't know the cable route for that feature because my controler is not available.my controler same as the one in your video
Thanks
Thank you very much!!
Hello! Today I got a controller from AZ like this one in the video with 2x red plugs for alarm, 3 x different 3 pin gas and 5 Hall sensors. But my problem is: I don't have a 5 pin display cable for the LCD display. You also don't have a display cable in this video. But I have about 15 cables high brake, low brake I understand all that. But I don't know how to do the display cable! PLEASE can Sue just help me and tell me how to make the display cable? The display cable is always the same as Hall sensors: red, black, green, yellow and blue. I have 1x blue cable communication send cable. Please, can you help me? PLEASE! Kind regards.

Hei sir. My controller hasnot cruise system. Can u make the video to make it?
Hi there, thanks for the video!
Is it possible that my board has the "EB" solder pad, but still doesn't support electronic braking?
On my board, all of the function pins are set up like this:
F1 - Gnd
F2 - Gnd
F3 - Gnd
F4 - Gnd
F5 - Gnd
EB - Gnd
All of the other working functions make a circuit to the gnd pin next to them, but when I connected EB to gnd nothing happens at all. Maybe it just doesn't support electronic braking? Or could it be that even though there is a gnd solder pad next to it, I actually have to connect it to 5v to activate, instead of ground?
Ooh. It could be a signaled function. Power to it rather than switch. Can you Google the board and find tech sheet?
Really useful and very nice video. It's going to be silly but I had a question :)
If we press the brake and turn the engine manually without giving any gas to the engine, will the engine brake thanks to ebs? so if the scooter stops on a slope with the brake pressed, will the scooter slide?
any answerrs ?
Yes, the motor will breaking (it will have some resistance) it will produce three phase power to the controller and the controller will convert it from AC to DC power to charge the battery pack of the vehicle.
Worth mentioning is that ebrake most commonly will be weak at low motor rpms, and stronger at higher motor rpms. So it will only give some resistance once the motor turns, making it a bad stand still brake. Of course there are other ways of actively keep a motor stopped, but thats not in the standard chinese ebike controllers.
For hoverboards, they have a special controaller that controls directly your motor torque, when standstill it applies a constant current the motor to keep you still
It also use a more advanced control technique cold FOC (field oriented control)
- Maximizes motor torque at any angle
- Better efficiency
- Sillent motor operation
- Precise motor movements
hello,
great video, but I have a question?
is it possible to to "brake" 2 speed controllers using 1 button?
I've turned a hoverboard into a go cart and need to activate the EBS on both controllers - easy done thanks to you - but can I ground out both controllers on the same ground wire?
FYI: Im using one batery to run both controllers so they share the same ground wire.
Correct..! the ground is shared from the battery so you must connect only the signal wires with one of two ground signal wires.
@@EVCustoms thankyou for confirming that, the controllers Im using have the antitheft wired to what you have called the EBS, can I use that as the "brakes" for my set up?
by grounding the EBS wire to apply magnetic braking?
@@MRLAW243anti theft is like full regen brake or ebs 100% on like lime or bird scooters when you push one around
Can you tell me how to connect the remote control to the motor drive
Hi can you connect stop light with this Ebs breaking? I can see you use the black cable from the low level break then the white from Ebs instead of red wire
My scooter controller just burned i replaced with another but it seems that it breaks by just turning the motor off not like the other was breaking very sudden
I think the burned controller had Ebs connected somehow on the mother board this one I need to make the connection like you did but then I don't know if my stop light will work
Also if high break connected with Ebs breaking will it be regen breaking or it will activate electric motor breaking where the wheel actually spinns opposite direction?
Yes... i have already video with this connection.. high and low braking video
@@EVCustoms will high break plus ebs use battery to reverse the motor or will it be regeneration breaking?
@@confidenceculture760anything that isn't reqen will draw power. You will have to find data sheet for your unit to see how the derived braking
Muy buenas!! Le he probado y funciona pero al parar en seco te puedes partir los dientes.Hay alguna manera de controlar la frenada con potenciómetro?
Te frena fuerte?
no

What happens if you vary the voltage going to that pin? I was under the impression that the degree of EBS could be carried linearly just like a throttle. So essentially you could have your normal throttle on one side, and a second throttle on the other side. The second throttle enables ebs and you can gradually increase the amount of EBS to slowly bring your bike to a stop. Could you test this by hooking that pin to a second throttle?
I imagine it should work. You might use regular 3-pin brake levers with a signal wire. I'll be testing this out with a xiaomi brake lever and will revert 🙂
But where to take the signal from..? Hmmm.
So to use ebs does that mean you disregard the high and low brake connections? Or is ebs a combination of high brakes and the additional contact you showed us to diagnose for?
@@jjpev Maybe using a ebike thumb throttle you could apply braking gradually rather than the off/on using a brake lever
@jrobpat0154 nahh i tryeddddd on my controaller and it didn't work like that
After a certain point the brakes just activate at full power
Your videos are super helpful! Thanks a lot! Is it possible to add a potentiometer for being able to dose the ebs?
Thank you Lucas.. No.. unfortunately there you will need special controller for analog EBS braking...
@@EVCustoms I am currently building two Bobby cars with electric scooter motors. Do you know how to make them faster than 35kmh? :)
@lucasfraunberger7914 what wattage and diameter wheels are you using?
@@joeKisonue I am using two 350w 8,5" motors (they have this red ring). max speed is 40kmh at the moment. thanks to @EVCUstoms I was able to activate the EBS. works great! :-)
@@LucasFraunberger increase voltage
Can you please make a video explaining how to wire up the alarm system
Hello friend... nice idea! i will put it on my list..
would there be a problem i dont connect the LOW BREAKE connector and instead use the switch as my breake light STOP switch?
Not if the brake lever is actuating rim brakes. If you aren't using the hub motor for brake and want analog brake and light
Great video, info and tutorial but I'm confused by one thing, if the EBS is activated to 100% when pressing brake, will it not cause the wheel to lock up??
If it's in locked position is it not better to connect that wire to the the kill switch?
When it's on 'off' position it will lock up the wheel and activate anti theft. I assume the ignition would have to be bypassed for it to work that way??
Hello dear sir I can see we as breaking. Thank 😊😅
Can this recharge the battery going down hill on every time applying the brakes?
Yes..
Hi, if i connect 48v to high brake cable, is it going to damage the controller....?
No... if you do that your controller will deactivate the motor (ebrake)
Hello dear friends the throttle wire looks good but I can't attach them to the control sensor because the wire's them are black and yellow and red 😊.
Can you do a tutorial how to install a display with a controller and with light connection?
Hi friend.. i will write it in my list
@@EVCustoms thanks👍🏼
if you break do you get Amps back into the battery?
Yes...
@@EVCustoms are u shure they are not shorted and dissipated as heat on power mosfets ?
@@gamer_5042one way to find out. With low battery, bring to top of big hill and see if braking raises battery level
i get max 4-6A brake Amps .... how to get stronger Regen? i want to stop in 20m or so...
Hi.. this is (maybe) because your battery is not discharged below than 60-50%. regen working at maximum when the battery has low capacity..
@@EVCustoms i get 4-6A on full and 30% 🤔
your controller is programmable?
What do I do if none of the pins trigger regen? Even if one pin is labeled EBS. When I connect that one it just takes out the ramp effect for acceleration. The label on the controller has a part that says “brake battery: +12v” what does this mean?
This +12v brake battery must be signal which you take from low voltage dc-dc converter pass from controller and handle which must be in series to activities the 12V stop lamp..
@@EVCustoms it only has a high brake wire. I would simply add a tap to the output that gives 12v signal and that should work?
request for a ebike with sound like bigbike
Can you please make wideo explaining how to wire the alarm with antitheft (wheel
are locking when someone tries to push the bike/scooter when alarm is actiwated )
My controler does not have that option originaly 😞
I have already order the alarm system for a learning table 😁
@@EVCustoms you are a star my friend😉 , from prewious wideo of you finding secret functions on controller, when you cut your plug for alarm i noticed to wchich pins 2 of the wires goes , i know where pink and blue wires goes and i have the same markings on my circuit board in my electric scooter , but the yelow wire didnt have any markings on the circuit board or i couldnt see it on the wideo, i have unused solder pad without the markings on my circuit board roughly in the same spot right next to the mosfets and i have theory that it goes directly to the thick solder trace for mosfets on the other side of the circuit board(i couldnt check it because i left my multimeter in work) , but im scared that its a wrong solder pad and i might burn something 😬
do you know the name of that plug that you cut ?
i want to buy one so i can solder it to circuit board and connect it nicely to original alarm plug , is it some kind of molex plug 🤔
I measured that pad with my multimeter and it does in fact go to the other side of the circuitboard , so I went for it and soldered green wire from alarm in there and 2 other wires to 2 other pads (im not gona spoil your wideo and say which wich 2 other pads ) and it worked 😀 wheel locks now when alarm is triggered and I try to push the scooter 😆 but its just one wheel that is locking , so ned to do the same wires in the other controler
I need to identify this controller.
Does the EBS Brake regen power back to the Battery on this cheap controllers?
Yes
But threres two types of braking on cheap controallers
The alarm that simply short your motor not regenerating any power
And the regen one (ussualy a bit less stronger) but recharges your battery
@@felipehcraftgamer4193 thx for your reply. I just tried the ebs brake from the alarm plug like you said no regen to battery. so I have to find the ebs brake on the controller because there is no wire outside from the controller and test it again!
@team13thirteen it's not that hard to find regen
With your motor running you just need to find the pad
In my case was
A3 Alarm motor lock
A2 regen
F5 speed toggle
F2, F3, F4 indicator led output for the speeds
XS low speed
DS motor desactivator
They are a few that i haven't tested such as
S1, L, ZL, DC
How would I activate EBS with the high brake line?
If your brake lever has a switch to light brake light you can run 2 wire into controller and solder one wire to each pad. Pulling lever will complete circuit and ground the ebs
Sorry I just read high brake line design. High requires 5v input
@@joeKisonue I decided to use a brake relay.
@@Fleshware good 👍
How to test voltage drop to motor?How to test voltage drop when not connect to motor?
I've been thinking about this. You need to make a harness with a female xt60 on in the middle of the positive lead.
Cann i ask?. can EBS be possible to charge while in the road hill down? Or not?
Yes
No matter what i do, my speed won't change. How do I adjust my speed?

Hello have?
Didn't catch that, again? Nah nothing, is he making curry?

I found A3 pin and EBS working for me but it is to strong !.Wheel just stop in 2s,you can do a flip,is it normal ?.
Perhaps Lov brake will be better/smoother ?.
BTW.thanks for your help, I successfully replaced the controller in the scooter of a girl from work.😁🛴
Try using low-brake instead. Low brake wire needs to be connected to ground to activate the brake
Is low brake and high brake the same as EBS?. Thank you
Yes my friend..
That it is not making sense, why would a controller have 3 plugs for EBS?
So, I am thinking that;
Low brake = soft motor shutdown
High Brake = hard motor shutdown
EBS = a gradual braking of the motor by slowly reversing the motor.
So, it is not the same, am I wrong?
@@diyek1781 They are same thing... the difference is tha on high brake you can connect load like rear stop light in series with brake leaver to activate stoplight when breaking
Ok, I shall try. Anyway, you always test on hub motors. Can you please provide tests of real motors like the skateboard motors 6374 at 190kv with the same type of controllers? Do this controllers work with the 6374 or are this just for hubs? Thank you.
