The blind rivet setting device according to claim 4, wherein the battery comprises a data storage medium containing charging information. 6. The blind rivet setting device according to claim 1, wherein the electric drive comprises an energy return feed. 7. The blind rivet setting device according to claim 1, wherein the electric drive is structured to act on the chuck housing via a ball screw having a pitch of about 4 mm and less than 5 mm. 8. The blind rivet setting device according to claim 7, wherein the ball screw comprises balls structured for a 5 mm pitch. 9. The blind rivet setting device according to claim 1, wherein the housing comprises a front face and a lighting device located on the front face. 10. The blind rivet setting device according to claim 9, wherein the lighting device is operable in at least two different modes. 11. The blind rivet setting device according to claim 1, wherein the battery is a rechargeable battery comprising a first encoding readable by the blind rivet setting device and a second encoding readable by a charging device. 12. The blind rivet setting device according to claim 1, wherein the battery is connectable to the housing via a sliding connection. 13. The blind rivet setting device according to claim 1, wherein the battery is secured in the housing by at least two mechanical locks arranged one after another in a sliding direction of a sliding connection. 14. The blind rivet setting device according to claim 1, wherein the pulling mechanism has a pulling distance of at least 25 mm. 15. The blind rivet setting device according to claim 1, wherein the pulling mechanism comprises a spindle coupled to the chuck housing and a rotatable nut to drive the spindle. 16. The blind rivet setting device according to claim 15, further comprising a transmission arranged between the electric drive and the rotatable nut. 17. The blind rivet setting device according to claim 1, wherein the clamping jaws comprise one of a fluting or surface treatment to improve a gripping of a mandrel by the clamping jaws. 18. The blind rivet setting device according to claim 1, wherein the ball screw comprises balls structured for a 5 mm pitch and the electric drive is structured to act on the chuck housing via a ball screw having a pitch of less than 5 mm. 19. A method of setting a blind rivet, using the blind rivet setting device of claim 1, said method comprising: grasping a mandrel of the blind rivet with clamping jaws biased to be linearly movable along a path obliquely oriented to a pulling direction of the mandrel; andpulling the mandrel until a set head is formed. 20. The method according to claim 19, wherein the pulling of the mandrel is achieved by pulling the chuck housing in which the clamping jaws are arranged via the electric drive. 21. The method of claim 20, further comprising determining a position of the chuck housing while pulling the mandrel by at least one of a single position sensor and a revolution counter.
