Hi Guys,
I want to show some parts of my personal Lime 3 Scooter that I am working on.
After I got my Scooter (from an auction) I took it apart and looked through the parts to see what im dealing with.
The thing that quite surprised me was the size of the battery. It is as big as some of the biggest e-bike batteries that I know about.
First I was thinking about using all the original parts of the scooter with the stuff that @M20001 had provided to this forum.
But then I went with the route that most people follow and use an off the shelf motor controller.
Since I hated the Idea of using the cheap Chinese controller, I used a VESC (I had one around anyway)
Original build to power Skate- and Long boards, it became some sort of an universal three phase motor controller with loads of power. I got mine from Flipsky. A company who copied (legally) the design and improved the power capability quite a bit.
Some technical data about the VESC:
It can run off Li-Po batteries up to 12S (44,4V) Absolute max Voltage is 60V
This board is able to withstand 100A of current with a peak of 400A (insane)
From previous e-bike projects I had two 6S Li-Pos with 12Ah laying around. They can provide 240A constant.
So my whole setup is rather beefy and got no issue squeezing all the (Lime) juice out of the poor little scooter.
Previously I even had a bluetooth connection and I was able to adjust everything with my Phone, plus I had gauges and stuff to monitor everything from speed to power and so on. Unfortunately that module died somehow.
Now I had to make a little Display for the scooter so I could Monitor some value information.
I used an Arduino Nano and I was able too connect it to the VESC with CAN Bus to get all the values I need.
Now I'm using a 16x2 Letter LCD Display to show me the Voltage and Current consumption, but also the max current and max power as seen in the two images below.
As you can see I got nearly 2.5kW of power (3.3HP)
I think the limiting factor is my max current setting in the VESC is at 51A
Eventually I'll test higher current settings, but I'm not sure if it will blow the motor winding.
From what I can tell it is still fine since the Temp sensor is giving me confidence that it is not getting too toasty. Will report back later on this one.
One nice feature is the working brake light and you can turn ON/OFF the headlight by pressing a button on the display.
