Differences of active balance and passive balance Passive balance
To drains a small amount of energy from high SOC cells using a switch and resistor inparallel with each cell. Passive balance allows all cells to have the same SOC. Andit provides a fairly low cost method for balancing the cells. But it waste energy intheprocess due to the discharge resistor.
With a balance current normally at 35mA to 80mA, passive balance is generally less accurate and slower than active balance. Active balance: Batteries designed around active balancing include advanced circuitry that works tobalance energy between cells without bleeding extra energy off to a resistor. As such, no energy is wasted in order to achieve balance. The circuitry moves energy aroundas needed to keep the batteries perfectly balanced.
Where charging is concerned, active balancing is the most efficient way to guaranteea set of batteries fully charges without any risks of overheating. As soon as full charge is achieved, on board circuitry stops the charging process. No batteries areindanger of overheating while the rest in the set catch up. When batteries are discharging, active balancing can actually extend battery lifequite a bit.
Again, this is because excess energy is not bled off. It is simplyredistributed so that all of the cells discharge at the same rate. You get longer lifebetween charges and very little risk of any single battery in a set fully discharging. For customers that wish to maximize system run-time and charge more efficiently, active balancing is the best option.
