Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: BQ40Z80, BQ34Z100

Hey, can I use BQ34Z100-G1 in standalone mode for gauging applications without using any AFE?

If so, what parameters (sensor data) are needed by BQ34Z100-G1??

Thanks

Hi Prabhat,

No AFE is needed with bq34z100-g1. Check out our quickstart guide here: www.ti.com/.../sluubv2.pdf

Thanks for the quick reply.

I have one more question.

In the datasheet, it is mentioned that it

Supports Battery Capacities up to 29Ahr with Standard Configuration Options
Supports Charge and Discharge Currents up to 32A with Standard Configuration Option

For my battery pack, I am expecting a peak discharge current of 250 Amps and a Charging current of 45 Amps. Can this gauge support in my design?

If so what are the changes I needed to make it work?

Does BQ34Z100-G1 also have a scale factor-like BQ40z80?

What is the difference between BQ34Z100 and BQ34Z100-G1?

In the datasheet of BQ34Z100, it is clearly mentioned that it supports a high current charge-discharge profile??
