The invention relates to a vehicle (4) with a high-voltage onboard electrical system (3) comprising a traction battery (5), a charging connection (6) for coupling to a DC charging station (2), high-voltage potential lines (HV+L, HV-L), and a reference potential line (ML). According to the invention, a DC-DC converter (7) is arranged in one of the high- voltage potential lines (HV+L, HV-L), and a series circuit made of a varistor (8) and a current measuring device (9) is arranged between the other high-voltage potential line (HV+L, HV-L) and the reference potential line (ML), wherein a processing unit (10) which is coupled to the current measuring device (9) and to the DC-DC converter (7) deactivates the DC-DC converter (7) if the current strength measured by the current measuring device (9) exceeds at least one specified threshold; or a respective DC-DC converter (7) is arranged in the two high-voltage potential lines (HV+L, HV-L), and a respective series circuit made of a varistor (8) and a current measuring device (9) is arranged between each of the high-voltage potential lines (HV+L, HV-L) and the reference potential line (ML), wherein a processing unit (10) which is coupled to the respective current measuring device (9) and to the DC-DC converters (7) deactivates the DC-DC converters (7) if the current strength measured by at least one of the current measuring devices (9) exceeds at least one specified threshold.
