Hi：

The algorithm for BQ41Z90 is Dynamic Z-Track ， From the EVM data, it can be seen that a ChemID that supports IT-DZT is needed. How to identify ChemID that supports IT-DZT?

Hi,

When you open the chemistry tab for BQ41z90 in BQstudio, only DZT chemid will show up.

Hello,

Looking for clarification: if the required ChemID isn’t listed under the Chemistry tab for the BQ41Z90 in bqStudio, does that mean this gauge can’t be used with that cell chemistry? If not, what’s the recommended way to support it?

Hi,

If the required ChemID isn’t listed under the Chemistry tab for the BQ41Z90 in bqStudio, it means that the chemid was created with DZT support, a new chemid will have to be made with DZT support, so the cells will need to get recharacterized. You can reach out to your supporting FAE or local ti office for help with this.

Diego
