It seems to my untrained thoughts, that passive cell balancers waste energy through bleeding energy off to resistors, active cell balancers have 20% losses sending charge between cells.....why not simply 'switch' the charge 'gate' on, for each cell according to the monitored voltage. ie the lowest first cell would start charging(solitary) until it reach the voltage of the next lowest. These two cells would then start charging till they reached the voltage of the third lowest cell and so on. No dissapating heat to burn off energy, no wasting energy transferred to another cell, only then to top up the cell that you took charge out of, to a higher level. Seems simple to me, but i guess there must be good reasons for BMS cell balancers appearing complex and wasteful. This would eventually ramp up to charging every cell to the max limit, but it could cut out a lot of heat build up in the early stages, thus prolonging battery life.
Still very much learning about this stuff....any thoughts why this would not be possible?
