Abstract: An apparatus is disclosed that includes a resistance measuring unit operable to determine a solution resistance Rsol and a charge transfer resistance Rct of a battery; and at least one computer-readable non-transitory storage medium comprising code, that, when executed by at least one processor, is operable to provide an estimate of the present value of the battery by: comparing Rsol and Rct to historical deterioration transition information; estimating the number of remaining charge cycles before a discharge capacity lower limit is reached by the battery using the comparison; and estimating the number of remaining charge cycles before a discharge time lower limit is reached by the battery using the comparison. The estimate of the present value of the battery includes the smaller of the number of remaining charge cycles before a discharge capacity lower limit is reached or the number of remaining charge cycles before a discharge time lower limit is reached.
