PURPOSE:To provide a voltage display device which can accurately display a voltage without introducing a high voltage directly into a cab when the voltage between terminals of a battery of a relatively high voltage is monitored to drive a motor. CONSTITUTION:The voltage between terminals 43 of a battery 18 is converted to a frequency by a V/F converter 44, and the frequency is converted to a voltage by an F/V converter 45. This voltage is displayed by a voltmeter 42 on an instrument panel 41. |
