A current sensor including a measurement circuit and an electrical conductor having at least one first measurement path defined by a first pickup contact and a second pick-up contact at which a first voltage can be detected across the first measurement path, a first connection contact for electrically contacting a connection element, a second connection contact for electrically contacting a battery pole terminal, and a current feed contact for electrically contacting a device for providing a calibration current. The first measurement path is in series between the first connection contact and the second connection contact. A calibration current supplied at the current feed contact induces a current density distribution in the first measurement path, which converges with a current density distribution in the first measurement path, induced by a load current of equal current intensity supplied at the first connection contact.
