Hi people,
I have some problems with my TinyBMS connecting to my win7 laptop and/or my win10 desktop for my e-scooter.
Backstory:
I know an awesome dude that made me a 16s18p panasonic PF battery pack (4.x kWh!) for my e-scooter. Lead batteries stripped, original controller stripped, he added mean two well led-drivers and configured them as a charger and he did basically almost all the wiring and the basic settings for tinyBMS and the kelly controllers (it is a 6-phase! moped).
So all good and cool at first glance and short test (at which point the USB cable with the cp21x chip dropped on the street and most likely broke on the inside, because of rattling sound, even though I didn't know this yet at that point) So I build the battery compartment and provided some wiring protection, and I was able to do a 20-35 minute test ride.
At the test ride, I felt the scooter was first slightly holding ''in'' when using the hand throttle, but then failed completely afterwards and I had to walk home a few kilometers.
When I arrived home I tried to connect the BMS to the win7 laptop to open batteryInside.exe and I couldn't get the BMS to talk with my laptop. Since there were some driver issues the first time (when it eventually worked for the guy who helped me) I tried reinstalling drivers, rolled the scooter to my desktop win10 PC and used multiple drivers for the usb-to-tinyBMS cable, all of them failed. At that point I saw the USB cable was crooked and it had a rattle inside it where the chip is hidden.
So I ordered 2x USB (original) cables for like 60euro and now the PC instantly recognizes the CP210x cable again when I connected it. However, no matter what I do, I can't seem to connect/talk to my BMS in order to reset it (fast green blinks on BMS, have been told it needs reset after looking at logs)
I have tried both USB cables for the past 6 hours, with two different compatible drivers on the win7 and the win10 PC. I have installed them with administrative rights and tried multiple USB ports for both PC's.
I can only see ''Scanning ports... '' and the green ''Tx'' blinking when I open battery insider. Also lists ''Not Connected''
FYI:
- It still starts a charge when connecting charger (quickly drops to 0-1w according to wattmeter in the wall, since the battery is full at 64.x v according to controller software that does work.
- BMS is Programmed at @4.05v per cell = full)
- Throttle doesn't respond, but according to kelly controller software, it does work (see values change)
- Motor hall sensors also work according to controllers (kelly) and visible hall sensors switching from 0-1
- When I had to walk home, sometimes when I put the scooter back on I was able to shortly still drive before it completely shut the engine down
- New USB cables are being recognized when connected to laptop without drivers installed, the old crooked usb wasn't recognized like that.
- When BMS is in fault (I suppose it is) the 12v lights and blinkers etc. still work
- BMS blinks fast green LED
- Once disconnecting BMS from battery pack (balancing wires before big +/-) and reconnecting it, BMS gives and audible *BEEP* and I was shortly able to control the motor again, and shortly the BMS had slower green led blinking. (But reverted to fast green blinks again)
Is there anything I miss or where I should look at? I can't find a lot of information on the internet to help me further.
The only thing I might want/can try is to install windows (7?) on my macbook to see if that would work and talk to the BMS.
Maybe you could point me in the right direction? please
