ABSTRACT:
A battery voltage measuring system includes an analog/digital converter configured to receive a higher reference voltage and a lower reference voltage which is lower than the higher reference voltage and to outputs a digital output value based on an input voltage which is lower than the high voltage reference voltage and is higher than the low voltage reference voltage. A battery supplies a battery voltage as the higher reference voltage to the analog/digital converter; a first power supply supplies a first reference voltage as the input voltage to the analog/digital converter; and a second power supply supplies a second reference voltage as the lower reference voltage to the analog/digital converter.
