Dear Support
I have problem with start BQ GUI for windows.
If I choose - COM10 (FTDI USB RS232 adapter, which is included to EVB) and then I press OK button, I got message Unable to open COM port. Why ?
I tested TTL UART included adapter, it is working. But I dont know how to set baudarate in my PC for this COM3, I can set x,x,x,x,x,115200,230400,460800, there is no option for 250kbaud. Chapter 7.1. is not useable, I got still error mesage from BQ PC APP. FTDi drivers - yes I used the last version, my system and computer in new (2020) W10 Pro is new .
Cell Voltages 46.8 (bat 0 - 16)
Vref 2.48
VIO 5.46
VDIG 5.28
VAO 5.25
VP1 5.28
CHP 2.55
VM 5.11
WAkEUP 0
D22 shine, it start shine if I try to connect to EVB byt Tera Terminal, If I try BQ app, LED is OFF. SW2 , BOTH are set to SINGLE Important question.
And important question:
Has EVB (BQ chip) discconect mosfets from all cells? I mean, what happens if I let connect EVB to battery pack (only) with poor capacity in my garage for 4 years? What is impedance of inputs B0-B16?
What is discharging current of every channel ?
Is there som possiblity to turned off BQ chip externaly by some pin (Wake Up) ?
Thank you
Regards
