Part Number: BQ40Z60 Hi TI Team,
We are using BQ40Z60 and 2 cells of Panasonic NCR18650B battery in series.
As specified in NCR18650B datasheet, the charging voltage should be 4.2+/-0.03V.
The output ripple & noise of the charger is 240mV max. The measured…
Hi Damian and others, I accidentally marked your reply as having solved my issue, instead of not solving. So to clarify, the issue is still present. Thanks again
Bronte,
Does the CC Gain and Capacity Gain values in the calibration section roughly match the size senseR you are using? for example 2.003 for a 2mOhm sense. If you manually adjust these parameters does the current value change?
Thanks,
Eric Vos
Part Number: BQ40Z60 Hi TI Community!
I have two of the BQ40Z60 evaluation boards (BQ40Z60EVM) and I have downloaded the corresponding TI Battery Manager Software. For one of these boards (Board 1), the FETs are working and I am able to toggle charge/discharge…
Part Number: BQ40Z60 Now there is one issue in the field that our BBU cannot charge to 100% RSOC from the log. May I know the reason?
Below is log from the field, the full charge capacity is 12.15Whr, remaining capacity is 10.68Whr. however, from the…
Part Number: BQ40Z60 Other Parts Discussed in Thread: BQ4050 Hi TI team,
I am working on the cell balancing of BQ40z60, I noticed that the cell balancing times are always updated only if the charging status() gets VCT (fully charged) or the battery gets…
Part Number: BQ40Z60 Other Parts Discussed in Thread: BQSTUDIO Here are several questions that I have regarding bring up of a custom PCB using the bq40z60.
1) Is it necessary to do a learning cycle in order to get the charging section to work?
2) I have…
Part Number: BQ40Z60 Other Parts Discussed in Thread: BQ27Z561-R2 Hi
In my application, the battery will be always cycled without relaxation so I enabled Fast Qmax Update (FAST_QMAX_FLD=1) to get Qmax update without relaxation. In my testing, I cycled…
Part Number: BQ40Z60 Hi TI team,
Looks like the output voltage of REGN is around 6V, I need more VGS voltage to drive the High SIde MOSFET for guaranteed low Rds On, so I am thinking to charge the bootstrap capacitor by the external supply voltage instead…
Part Number: BQ40Z60 Hi, (long time reader, first time poster!!) I have read many conflicting posts regarding the slave address for the BQ40Z60, some say 0x16 and whereas others say 0x17. Where in the Technical Reference Manual can I find the slave address…
