Abstract
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.

12. A Power supply device comprising:
-
a detection circuit that detects internal resistance, temperature, and SOC of a battery; a memory circuit that stores record data and a predetermined SOC range as storage data, the record data being used for estimating standardized available output power at standard SOC and standard temperature corresponding to the detected internal resistance and temperature of the battery; and a determination circuit that, if determining that the detected SOC of the battery falls within the predetermined SOC range, estimates standardized available output power of the battery at the standard SOC and the standard temperature based on the detected internal resistance and temperature of the battery, which are detected by the detection circuit, and the record data, which is stored in the memory circuit, wherein when the internal resistance, the temperature, and the SOC of the battery are detected by said detection circuit, in comparison between the detected SOC with the predetermined SOC range, which is stored in the memory circuit, if determining that the detected SOC falls within the predetermined SOC range, said determination circuit estimate the standardized available output power at the standard SOC and the standard temperature based on the detected internal resistance and temperature of the battery, and the record data. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
