There is very little describing how the BQ76PL455 actually performs cell balancing.
I need to ensure that the individual balancing circuits are correct from the BMC to the cell connection .
How would I test that a individual cell balancing circuit is working end to end
i.e How can I trigger get the BMC to turn on an individual EQn line.
I.e If I use a set of dacs and op amps to simulate the cell voltages without having any batteries actually attached and then make the cell that I want the balancing to turn on 200mV higher then all the rest. With the rest being say within 20mV and then turn on cell balancing for that cell. Will I immediately see the EQ turn on ?
When the EQn lines are turned on during Load balancing Is this a PWM signal or a constant.
Is there a fault check that will turn it off if the voltage does not start to drop.
How long does the signal remain on for.
