Part Number: BQ40Z50-R2 Following the battery learning process, we obtained the chemical parameters.
However, using chemical IDs 8227, 7810, and 7471 with lower error rates, we were unable to jump to 0X05.
But using ID 7821 with a higher error rate…
Part Number: BQ40Z50-R1 Other Parts Discussed in Thread: BQ40Z50 , BQSTUDIO Hi ,
The configured charge current is 2048 mA for our system.However, during charging, once the battery reaches approximately 70% SOC, the charge current begins to gradually…
Part Number: BQ40Z50-R1 Other Parts Discussed in Thread: BQ40Z50 , BQ4050 , BQ78350 Dear TI Engineer,
We are wondering if TI can provide the srec firmware burning guide for BQ40Z50 (as will as BQ4050). So that we can build our own production software…
Part Number: BQ40Z50-R1 Other Parts Discussed in Thread: BQ40Z50 , GPCCHEM Previously, we were using a 3.7V, 2600mAh 18650 Li-ion battery pack with BQ40Z50 BMS System. We are now upgrading to a 3.7V, 5200mAh 21700 Li-ion battery with same BQ40Z50 system…
Hello Sumedth,
The drop voltage on the waveforms does not look to be able to reach all the way to zero (at least in the yellow channel). Are you using the EV2400 for communication? Can you check your system is not adding any capacitance to the lines…
Part Number: BQ40Z50 hi ALL
For the BQ40Z50 FWR3.09, in the static state, FCC/RMC/SOC, etc. are updated every 5 hours. Due to design requirements, it is necessary to disable this update situation and keep the SOC from being updated in the Relax mode…
Part Number: BQ40Z50 Other Parts Discussed in Thread: BQSTUDIO Hi TI Support Team,
I am working with BQ40Z50-R4, attempting to read the 'Update Status' byte using MCP2221A CLI, monitoring the byte through reads to conduct the learning cycle using automatic…
Part Number: BQ40Z50 Other Parts Discussed in Thread: BQSTUDIO We have a design that uses BQ40Z50 (R4 firmware) as the BMS. The battery pack is a 4S1P design, using 4 pouch cells that are lithium iron phosphate. Our charge is set to terminate due to VCT…
Part Number: BQ40Z50-R1 Other Parts Discussed in Thread: BQ40Z50 HI, Are there any implications of connecting the BQ40Z50's SMBus interface directly to a 3.3V MCU without level translatio n?
