Part Number: BQ34110
I am trying to set up 8S Lifepo4 guage bq34110 under BQStudion, unfortunatelly without sucess, is ther somebody who can help? Advances? step-by-step instructions, exmaples, BQ projects?
(working with bq34110EVM-796 board)
thanks a lot

Hi Valentin, The log for the GPCCHEM tool should be run at room temp. Using 1S for the GPCCHEM tool will work well. With respect to the 8S configuration, the external jumpers will need to be utilized. Place the jumpers of the EVM into >5 mode and the divider jumpers to 36 V. Set the Series = 8 and VEN_EN = 1. Now calibrate the voltage in the calibration tab of bqStudio. This will automatically modify the voltage divider value for you. Sincerely, Bryan Kahler
Thank you Brian,
Unfortunatelly this does not work with current set-up using EV2300 rev.m, will wait for EV2400 (ordered last week) hope it will work and can try agin.
Let see if EV2400 will work as should otherwise it was just loosing of time and money.
Thank you for answer, short summary - does not work for 8S config
EV2400 arrived today, we currently have alredy 2x EV2300 and EV2400, after powering set-up on, looks it behaves the same (same issues), not responding to changes of "Number of Cells" neither of VEN_EN, IC on the board is ok, replaced with new one without functionality change. Photo of the setup attached.
BQstudio dashbord after starting, as you can notice there is no voltage indicated, this issue can be related to no voltage on measured bucesue dafultly VEN_EN is set to 0 (factory settings), I believe this is a reason, due to "Flash update OK voltage" - not documented
if I connect two white vires to get VEN_EN working board indicates just 607 mV (below 1V as recommended), but still not possible tio update values in BQ studion:
see notice at the bottom: "A read of datawritten failed comparision"
Connecting REGON to divider output, increases voltage to REGIN value that is above "Flash update OK voltage" 2800mV, now it is possible to change settings
connection on the board:
afterwords I have changed "Flash Update OK Value" to 500mV
now we change VEN_EN, BTW: it should be marked in bqstudio what colors means green 0, red 1, not to loook around...
after disconnectionall artifical wires from board, board finally indicates voltage 3545 mV, No of cells is just 1
now let continue with your recommndations step by step
No of series cells changed to 8, written
voltage remains the same, but setting cannot be changed again,...
reading of values works, writting not
i think there is serious problem with this eval kit type, I propose to check it yourself.
looking forward hearing from you
