Abstract
The measurement unit measures a voltage by converting it from analog to digital and outputs a measurement value. The changeover unit, being connected to a battery and a reference voltage source generating a highly accurate fixed voltage, selects one of them and applies it to the measurement unit. The voltage value output unit makes the changeover unit select a fixed voltage generated by a predetermined voltage source, makes the measurement unit measure it as a reference voltage and generates calculation-use information for calculating a voltage value from a measurement result based on a measurement value of the fixed voltage and a voltage value of the reference voltage. The voltage value output unit, when making the changeover unit select a voltage of the battery and making the measurement unit measure it, uses the measurement value of it and the calculation-use information to calculate and output a voltage value of the battery.
