Other Parts Discussed in Thread: BQSTUDIO, BQ34Z100

1.Golden image writing tool

In Data sheet, Smart Flash is described as bellow for writing tool at production line.

Is it possible customer to buy it ?

If it is, how many devices could be written at once ?

***********

TI provides production tools (bqStudio and SmartFlash) to program flash or OTP memory during production. After the gauge configuration is completed during development using bqStudio and a gauge EVM, bqStudio generates a Golden Image with the gauge configuration. TI production tools use this Golden Image file to program flash or OTP memory.

2 CycleCount().

bq34z100 is used for pack side.

When battery is changed, customer want to initialize the CycleCount().

Is it correct to write data 0 for bellows registers ?

Kanao-san,

I will have to look into this and find out. I don't think smartflash is a BMS product. Please allow me until Tuesday to find out about this for you.

Hi, Kanao San

For Pack side gauge, the typical procedure after pack assembled is to write golden image to the target device. Then send IT Enable command after the battery is well relaxed.

Does customer change the battery in the field? or in the factory?

Regards

Steven

It is not right to simply change the cycle count, customer has to download the golden image to the gauge and then send IT enable command with battery well relaxed.
