The invention relates to a ground terminal and to a method for discharging electric currents from a rotor part of a vehicle (such as a rail vehicle or the like, that has an axle) to a stationary stator part of the vehicle. The ground terminal includes a retaining device and a terminal element. The retaining device is connected to the stationary stator part of the vehicle in electrically-conductive manner, the terminal element is disposed on and connected to the retaining in electrically-conductive manner. The terminal element is made mostly of graphite and subjected to a contact force by means of a spring device of the retaining device to realize an electrically-conductive sliding contact between a sliding contact surface of the terminal element provided for realizing the sliding contact and a terminal surface of the rotor part. The terminal element has an arc-shaped cross-section at least in portions thereof, an outer surface of the cross-section forming the sliding contact surface at least in sections. The sliding contact surface abuts radially against the terminal surface of the rotor part.
