A cell balancing method includes: setting predicted standing time, based on a statistic value of standing time collected over a predetermined period of time; estimating a capacity retention rate of each of cells of a lithium-ion battery at a next start-up after a lapse of the predicted standing time; on the condition that a difference in the estimated capacity retention rate between a maximum value and a minimum value becomes greater than a predetermined value, setting state-of-charge adjustment values for one or both of a cell having the maximum value and a cell having the minimum value; and allowing, during the stoppage of the electric vehicle, a state-of-charge adjustment device to adjust the states of charge of one or both of the cell having the maximum value and the cell having the minimum value to the state-of-charge adjustment values.
