Which 3 wires are for throttle on this controller??

[AC-EUV]

I am trying to use this small 36v controller which was once in an electric scooter and just want to connect a standard 3 pin throttle to it


After attaching the motor, phase wires and the battery I only have these two plugs left over, (the bottom two on the picture attached)
There is a plug with 5 wires and a small plug with just red and black

I'm presuming the plug with 5 wires has the throttle in amongst it but not sure which wires are which
and I think previously this may have been plugged into a display unit on the scooter handlebars (I'm guessing hence why 5 wires and not 3 for just the throttle)

If so can anyone tell me which colour wires are just the 3 throttle wires?

Also what is the smaller black and red plug for ?

Only way I see is to open the box. With luck the pcb has annotations. But I don't think there is a throttle; all I see from top left to bottom right is: battery, motor phases, motor halls, light and display.

I have opened up the case and there is nothing written on the circuit board regarding the 5 wire plug unfortunately

I think it's the display which the throttle was connected to

Many scooters use this…



…display. It’s got a 5 pin plug. Here is some link about the manual.

1. It could be a 5 wire handlebar unit with on/off switch and throttle.
Power/Ground
Srart lead
5V throttle
Throttle SIgnal

2. It could be a 5 wire display connection with built in digital throttle interface -
Power/Ground (36V)
Start Lead (36V)
Data in
Data out

If you go to the Lenzod website, my guess is it's this one, Two plugs . 5 pins and 2 pins, You can browse their site. Your controller is in there. Look at the other handlebar stuff.

A google for "lenzod" from the label on your controller, wihtout even a model number, finds numerous things like this

https://www.aliexpress.us/item/3256806960269020.html

that use a display with a throttle built in or a display wiht a throttle connector on it....and wihtout that specific display, they're not usable.

The throttle is not sent as a separate signal to the controller; it's mixed in the serial data, so there is nowhere on the controller itself to connect a throttle.

Yours is probably the same. If you look around the web for the model of scooter your controller came from, you can find the display type that it used, and get one of those made for your specific controller, and then possibly be able to use this controller for your project.

I saw the controller on Amazon, and in the description details, regarding how to use it, it says "just wire it up". How hard could it be, lol.




It also says the conductors are all color coded to make things easier.

That makes sense. I have a clone of the Xaiomi M365. If you look at the OPs white connector, they are the same as your link. The display connects to the big white 5 wire connector and the 2 wire is for the brake light. The throttle will connect to the display and not to the controller.

I wasn't sure originally if the throttle and signal line was in that 5 pin plug but it seems it isn't.
So I will scrap the idea of using this controller now.

I have just purchased a new basic controller as they are cheap enough

So no worries
Thanks for the help all

Well it is, but the signal is digital, not an analog voltage signal.

The look at scooter display technology was interesting, Digital throttle interface. They can probably activate regen braking that way too,

I researched it for a bit, but didn’t add it to my faq since they are almost always used with scooters, not e-bikes. There was one thread on ES that I saw one working on an ebike. Plus those scooter controllers have different options, like pushing off before the motor engages, etc.

Those scooters usually have a set amount of regen. You can’t modulate it. When you activate the brake, regen automatically kicks in.

These displays are similar (not really) to a cycle analyst. Inputs connect to the display first.

Displays might have an app available. You can change settings such as speed limit (for Eco, Drive, Speed), cruise, or regen. You can even view minor battery info like capacity and voltage.
