Part Number: BQ40Z50-R2 Hello,
We are using the bq40z50-R2 for our 4S1P and 4S2P battery packs. We are currently considering moving from our traditional age and cycle limits to a dynamic, State-of-Health (SOH) based limit for retiring packs. To implement…

The customer is using BQ40Z50 for design. Please help review the schematic diagram to see if it is reasonable. Thank you~
Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQSTUDIO , BQ40Z50 , EV2400 We are currently developing a BQ40Z50-R2–based Battery Management System PCB. However, the device is not establishing communication with the bqStudio software.
We monitored…
Part Number: BQ40Z50-R2 Dear TI Support Team,
I am currently working on a project that requires integration of the BQ40Z50-R2 fuel gauge. I would like to request the following information/resources:
Linux driver support for the BQ40Z50-R2 (if…
Hello Sylvain,
FOSSAERT Sylvain said: If IT gauging is disabled in the golden file, how are Qmax, Ra, SOH and battery capacity expected to evolve over time in the field?
Changing the update status from 0x0E to 0x02 stops the bypassing of the GAUGE_EN…
Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQ40Z50 , BQSTUDIO In my task of coding MCU to communication with bq40z50 over SMBus, it seems bq40z50 does not support clock stretching. The SMBus Read-Word operation to read Temperature() fails…
Part Number: BQ40Z50-R2 Other Parts Discussed in Thread: BQSTUDIO , BQ40Z50 , BQ40Z80 Dear TI Support Team,
I am currently working with the BQ40Z50-R2 fuel gauge device. I am referring to the application note SLUA801 for the learning cycle and calibration…
Part Number: BQ40Z50-R2 Hello We are using the bq40z50-R2 with a 4S3P cell configuration and communicating with a Nuvoton controller (P/N: M487KMCAN) over SMBus. During battery charging, we observe that the SMBus current reading from the bq40z50-R2 randomly…
Relly Chu said: Does this mean it will affect the Gauge's calculations? And will it impact any internal parameters that update automatically, such as Cycle Count or Qmax?
For a real application, you need the gauge wait for the SoC to update, the same…
