Why the cell balancing in bms is necessary for your battery?

Active Cell Balancing. In active cell balancing in BMS, energy moves from cells with higher voltage to those with lower voltage within the battery. This process actively ensures that the battery with a higher state of charge (SoC) transfers its energy to the battery with a lower state of charge, effectively preventing the loss of heat energy.
