Other Parts Discussed in Thread: BQEVSW

Dear Sir ,

Our supplier used BQ20z655-R1 to design 4s2P battery pack. The cell is chose Panasonic: UR18650NSX (2600mAh) ,but the supplier use chem ID is 2068 ,because 2068 is reference from TI .

I down load the chemistry selection table form TI website and i can see our cell Panasonic: UR18650NSX (2600mAh) chemistry ID is 2067.

I could't find chem ID 2068 in the cell chemical ID list on BQ Evaluation Software(Version 0.9.80).

The chemistry select table only can support 0100 to 0800.

Clould you help to provide the chemistry ID is 2067 and 2068 for me to update chemistry table on BQ Evaluation Software(Version 0.9.80)?

Thanks!

Hi Steven，

Thanks ,update chemical successful.

If i want to update the battery pack chem ID , first setup ,i need to choose the current chem ID ,such as 2067 , second , click the table "OK-Update Fuel Gauge Data Flash‘’ ，do the two setups , Whether it means the chem ID update is successful ? Is need to do learning two cycles?

Thanks ！

This picture suggests the chemistry update is successful, you still need to do learning cycle after this the chemistry is updated
