As shown in the figure, the battery pack is output to an isolated switching power supply, and the switching power supply is output to charge B2 in it, then I would like to ask: should B2 be charging or discharging? How does the electron flow?

Principle of Active Battery Balance
Take the entire battery pack to charge a single battery

So how to understand Kirchhoff's theory, if the current direction of B2 is charging, it should be the opposite of discharging. How does the charge flow from B1 to B2 go?

Is it hard to understand?
Think about it yourself
Discharging current is one thing, and charging current is another. The two are relatively independent circuits.

Finally, the energy of the two batteries at both ends is transferred to the middle battery. The direction of the current transient is related to the end of the transformer with the same name.
