I have looked at a few of these BMS boards and they seem to work on controlling the negative line . Cutting off current or connecting it via a bank of MOSFETs.
Straight forward stuff I guess when the gate is set with a certain voltage ,current either flows or doesn't through them depending on PNP or NPN .
So I'm looking at the one below and trying to figure out what the circuit would be . Does anybody have a clue how they work to sense the individual voltages and switch on or off the whole bank?
What would the main current flow look like? Could anybody venture a circuit?
