The high efficiency of a switching regulator significantly increases the achievable balancing current while reducing heat generation. Active balancing also allows for capacity recovery in stacks of mismatched batteries, a feat unattainable with passive balance systems. In a typical system, greater than 99% of the total battery capacity can be recovered. The LT8584 includes an integrated 6A, 50V power switch, reducing the design complexity of the application circuit. The part runs completely off of the cell which it is dischargi...
