Abstract: In an arithmetic processing apparatus with a charge-discharge switching device for switching between a charge and a discharge of a secondary battery, a processor is provided for calculating an internal resistance or an open-circuit voltage of the secondary battery based on data including a voltage detected by a voltage sensor and a current detected by a current sensor. The processor is configured to derive an IV characteristic by using at least one of charging-period voltage and current data and discharging-period voltage and current data detected after a predetermined time has expired from a charge/discharge switching point, without using the voltage and current data of the secondary battery detected during a time duration from the charge/discharge switching point to the predetermined time, and configured to calculate the internal resistance or the open-circuit voltage from the derived IV characteristic.
