To sufficiently exert charging and discharging performance of a cell while reliably protecting the cell, a battery controller determines ΔVlimit which is a limit value for a difference between a CCV and an OCV of a cell module, which is a secondary cell, and determines at least one of an upper limit voltage and a lower limit voltage of the cell module. An allowable current of the cell module is calculated based on the ΔVlimit and at least one of the upper limit voltage and the lower limit voltage determined in this manner.
