The control unit is configured to calculate a charge capacity and a discharge capacity in a kth charge/discharge cycle, determine a capacity difference corresponding to a difference between the charge capacity and the discharge capacity, determine a kth capacity difference change amount by subtracting the capacity difference of the kth charge/discharge cycle from a capacity difference of a k-1th charge/discharge cycle, update an accumulated capacity difference change amount by adding the kth capacity difference change amount to the accumulated capacity difference change amount, and diagnose that a lithium precipitation abnormality occurs when the updated accumulated capacity difference change amount is greater than or equal to a threshold value.",
