Abstract
A device is provided that allows a physical quantity of a battery pack to be determined at low cost with high accuracy with respect to variations in environmental temperature. A voltage regulator supplies a temperature detecting part and an A/D converter with reference voltages as a reference voltage for detection and a reference voltage for conversion, respectively, and supplies a storage part and a signal processing part with the reference voltage as a supply voltage. Based on signal levels obtained from physical quantity detecting parts and the temperature detecting part via the A/D converter so as to correspond to a plurality of temperatures in a predetermined temperature range, which have been stored in the storage part, a signal level obtained from the physical quantity detecting part via the A/D converter is corrected in the signal processing part.
