Abstract
A power system for a vehicle may include at least one controller and a battery having a plurality of cells. The at least one controller may, for each of the cells, determine a voltage of the cell, determine a discharge time to reduce the voltage to a value approximately equal to a minimum of the determined voltages, and cause the cell to discharge for the discharge time to balance the battery.
