Why the cell balancing in bms is necessary for your 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. Instead, active balancing BMS employs shuttling or converters to equalize the energy levels between the highest and lowest voltage cells.
What is Battery Balancing and Does Your System Need It?
