Abstract
The present invention is to provide a voltage detecting device connected to an ungrounded high-voltage battery which is connected to a high-voltage conducting path becoming a charge and discharge path, the voltage detecting device detecting at least one of a ground fault of a system in which the high-voltage battery is arranged and a voltage of the high-voltage battery. The voltage detecting device has a magnetic switch in which ON/OFF is switched based on magnetic field generated by current flowing through the high-voltage conducting path. The magnetic switch switches between a first measuring condition and a second measuring condition different from the first measuring condition in a measuring circuit or a measuring parameter.
