Update BQ34Z100 with BQ34Z100-G1 new firmware

Other Parts Discussed in Thread: BQ34Z100, BQ34Z100-G1, BQSTUDIO

Hi,

I got to know we can update existing BQ34Z100 with the new firmware for BQ34Z100-G1. Would like to find out does the old BQ34Z100 works exactly the same as BQ34Z100-G1 after firmware upgrade? Is there any noticeable difference?

To perform firmware upgrade and update it with data for learned pack, the proper procedures will be flash the old chip with BQ34Z100-G1 srec file using bqStudio then write the related parameters of previous learned pack into the data memory?

Thanks.

The bq34z100-G1 does not work exactly the same as the older device. The most notable difference is that we added a capacity smoothing filter to provide a smooth SOC profile for pulsed load applications. You can update your existing device with the srec file and copy the learned parameters to the data flash.

Hi Tom,

Thanks for your fast response. I did read in another post and understand that the difference between BQ34Z100 and BQ34Z100-G1 is on the firmware side only.

Therefore, after update the old device with new srec file, it will work similar with BQ34Z100-G1 which should be able to solve the SOC jumps problem?

Yes, the firmware was updated to reduce the SOC jumps. There are no hardware changes.
