BQ25892: BQ25892

Part Number: BQ25892
Other Parts Discussed in Thread: BQ28Z610, , BQSTUDIO

Hi, 

I am using "battery management studio 1.3.90"  by connecting bq25892 and bq28z610. 

As you see below, I  can read and write these two devices by using advanced communication tab of this tool. BUT, I can only see one device set of registers ( not two devices at the same time ). I want to charge, discharge the battery manually by using this software( battery management studio 1.3.90 ) while connecting charger ( bq25892 ) and gauge (bq28z610) at the same time. 

What should I do?  

I also try to open two instances of this software. But in that case , only one instance can talk to ev2300 . 

Thanks and best regards

    Hi Redwood,

    BQStudio can only access one device through a single EV2300 at a time.  However, you can use 2 EV2300/2400s and 2 instances of BQStudio if you power up as follows:

    1. Plug in EV2300/2400 #1

    2. Start BQStudio #1 and access either the gauge or charger EVM

    3. Plug in EV2300/2400 #2

    4. Start BQStudio #2 and access the other EVM.

    Regards,

    Jeff
