Claim Text:
1. 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 estimated standardized available output power at standard SOC and standard temperature at the detected internal resistance and temperature of the battery; and a determination circuit that, when the internal resistance, the temperature, and the SOC of the battery are detected by said detection circuit, in a comparison between the detected SOC with the predetermined SOC range, which is stored in the memory circuit, if it is determined 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 at 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.
