I am new to this but yesterday managed to compile the code with no issues except that I had to comment out the following lines from the makefile-windows:
# @$(ENTF) *.asm
# @$(ENTF) *.rel
# @$(ENTF) *.lk
# @$(ENTF) *.lst
# @$(ENTF) *.rst
# @$(ENTF) *.sym
# @$(ENTF) *.cdb
# @$(ENTF) *.map
# @$(ENTF) *.elf
# @$(ENTF) *.adb
It used to get stuck on the cleaning stage and not progress to compiling. I am not sure why these are in the makefile just after clean.bat which does the same.
Anyways, instructions are good if I managed to do it. Thanks for that.
I also fitted the 72v 18fet sinewave controller to the bike and ran it with the standard firmware to make sure halls and phases are wired right.
Also overvolted it to 24s (100v) with the only modification beeing fitting a dc-dc switching regulator instead of the lm317s. Caps and mosfets beeing rated at 100v seem to be doing just fine after 1 day of riding.
Now before flashing the firmware I have a few questions:
1. Is the firmware compatible with the 72v 3kw 18fet controller? It has the current sensor on one of the phases.
2. How does it perform compared to the stock formware? The notes say something about block commutation not available yet. I can feel the motor currently starting in non-sinewave mode and then switches to noiseless shortly after.
3. Does it show battery voltage on LCD3?
3. Do I need to reflash LCD3 with alternative code?
Thank you for your help. Although not a programmer by trade I have some experince and I am looking forward to understanding the code and possibly helping improve it as much as I can.
Hello guys,
Great to see all this good work around the kt controllers.
I myself would like to upgrade my 18 fet 48v kt controller to allow for up to a 72v 20s battery. I know many of you have tried or done this before, but I cannot find a complete overview of the steps to take. I already have ordered the following:
- low esr 100v 1000uF caps
- 50 pieces irfb4110 100v mosfets (“original disassembly”)
I need the following information:
- schematic of the location and pins of the components on the pcb of the 18fet kt controller
- I am planning to bypass the lm317s (if I know where to find it) with a dc-dc converter. Does it need to supply 15v or could this also be 12v?
- I would really like to use a Bluetooth dongle instead of my current kt-lcd3 Display (48v). How do I make sure I supply the correct voltage to this dongle/display connector? For simplicity, I would also like to use a dc-dc converter for this.
- what other components do I need to upgrade to enable 72v (84V peak) battery voltage?
I am sure more users have the same questions, so if somebody can provide feedback on the missing info that would be highly appreciated!
Also, I am interested in doubling the mosfets for a higher amp rating, as I will soon have plenty of fets lying around. Did anyone suCees in making this work by now?
Hoping to squeeze as much cheap power from this nice controller as possible!
