1. A method for producing a traction battery, comprising:
arranging at least one cell module having multiple battery cells in the traction battery, providing each of the multiple battery cells with a separate temperature sensor;
arranging at least one temperature sensor on a metal carrier;
welding the metal carrier to a cell housing of the respective battery cell, wherein the metal carrier has a retaining foot which is wider than a connecting region carrying the at least one temperature sensor, the retaining foot is continuous with the connecting region, and is welded to an upper surface of the cell housing of the respective battery cell; and
wherein each of the multiple battery cells has at least one terminal for electrical contact and the at least one terminal of each of the multiple battery cells is electrically connected to one another via a common connector, welding the common connector to the at least one terminal of each of the multiple battery cells by means of a same laser head as the metal carrier is welded to the cell housing.
