A power supply device according to the present invention includes a detector, a memory, and a determinator. The detector detects internal resistance, temperature, and SOC of a battery. The memory stores record data and a predetermined SOC range as storage data. The record data is used for estimating standardized available power at standard SOC temperature corresponding to the detected internal resistance and temperature. If the detected SOC of the battery falls within the range, the determinator estimates standardized available power at the standard SOC and temperature based on the detected internal resistance and temperature, and the record data. When the internal resistance, temperature, and SOC are detected by the detector, if the detected SOC falls within the range, the determinator estimates standardized available power at standard SOC temperature based on the detected internal resistance and temperature, and the record data.
