BQ78350-R1: BQ78350 - R1

Hi Alexander,
Since it is a test it is not a monitored operation. You would not want to imbalance your cells with test.
We don't have a specific recommendation, it would depend on how you want to observe it.
If you have multiple low impedance sources you could observe the current from those sources. You could also look at the voltages across resistors on the boards. When using a large value resistor divider the simulated cell voltage will collapse, certainly it depends on the balance current you are using. Using a 200 ohm resistor divider as on the EVM the voltages collapse substantially. As your divider resistors become smaller (source impedance is lower) the movement becomes smaller but the power in the divider gets higher. Adding capacitance across each resistor in the divider helps also but the balancing period is 250ms.
Hope these thoughts help you select a method.

Hi Alexander,
You might see the app note on the scheduler. Balancing will be on 70% of the 250 ms scheduler interval or 175 ms.
The command 0x1B actually does not use the cell map as stated in the technical reference manual. It will balance odd cells on the first transmission, this will balance the adjacent cells 8&9 and 12&13 in your 13s configuration. This is not generally recommended but these higher cells have higher voltage tolerance and should not exceed abs max if you control the voltage during test. Also if you use external cell balancing, control your cell voltages to check both external balancing FETs if tested in this manner.
