The invention relates to an electrically driven motor vehicle (20) having a vehicle chassis (22) and having a first current collector (26) and a second current collector (28) for respectively contacting trolley wires (4, 6) of a bipolar trolley wire device (2). Furthermore, the motor vehicle (20) comprises a device for determining a voltage between the vehicle chassis (22) and the first current collector (26) and/or a voltage between the vehicle chassis (22) and the second current collector (28), the device being formed by means of a bridge circuit having two voltage divider resistors (40) connected in series between the two current collectors (26, 28), the voltage divider resistors having the same resistance, and the voltage divider resistors (40) being connected in series between the two current collectors (26, 28). Wherein the bridge resistor (52) is electrically connected to the first center taps (44) of the two voltage divider resistors (40), and wherein the bridge resistor (52) is connected to the vehicle chassis (22) or can be connected to the vehicle chassis (22) by means of a switch (54), or wherein the device comprises two voltage measuring devices (74), the voltage sensor is used for determining the voltage between the first current collector (26) and the vehicle chassis (22) and the voltage between the second current collector (28) and the vehicle chassis (22). The invention further relates to a method for operating such a motor vehicle (20) and to a system having such a motor vehicle (20) and a bipolar trolley connection device (2).
