A controller discharges a traction battery according to power limits defined by output that is indicative of a state of charge of the traction battery and is updated by a bar delta filter according to a balancing current. The balancing current is associated with each cell of a string of series connected cells of the traction battery and represents a deviation of an estimated current through the cell from a total current of the string.
