A monitoring device for a high-voltage onboard electrical system of an electrically operable vehicle. The high-voltage onboard electrical system includes a high-voltage energy storage device that is couplable to an electrically positive and an electrically negative charge line. The electrically positive charge line is couplable to a positive electric voltage of a charging device via a charging connection to charge the high-voltage energy storage device and the electrically negative charge line is couplable to a negative electric voltage of the charging device to charge the high voltage energy storage device. The monitoring device has a control unit with a current sensor which is configured to determine the sum of the electric currents of the positive and the negative charge lines. The control unit is configured to separate the positive and the negative charge lines from the high-voltage onboard electrical system upon detecting a fault.
