Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: BQSTUDIO, , EV2400

Hello Team,

We have a 13S3P Lithium-ion (Lithium iron phosphate) Battery of max voltage 54.6 nominal voltage 48V and normal amps of 4A. We wanted to know

what is cell charge voltage

T1-T2

T2-T3

T3-T4

Since only these 4 are avilable in BQstudio.

We are using EV2400 to communicate with BQ34Z100-G1

Also how do we figure out cell taper voltage,taper window,CC threshold and min taper capacity of our battery

Thanks

Hello Bhanu,

All this information comes from the cell data sheet.

T1-T2 refers to the temperature range as per the JEITA charging profile. This is used by the charger.

See 2.2.11 ChargeVoltage(): 0x30/0x31

Hello Shirish,

To only monitor SOC,Voltage,Current and Temperature do we need to enter all the values in the Data memory configuration of BQStudio or are there any main important parameters we can focus on.

Thanks

Hello Bhanu,

The parameters listed above are related to charging and do not affect SOC, Voltage, Current and temperature
