1. A method for producing a traction battery of a motor vehicle, the method comprising:
receiving a cell module to be inserted into a receiving compartment of a battery housing, wherein the receiving compartment is delimited by a bottom and walls adjoining the bottom,
recording a topography of the bottom using an optical measuring device,
calculating an amount of thermal conductor to apply, wherein the amount of thermal conductor is determined by the topography, and
after determining an amount of thermal conductor to apply, subsequently applying the thermal conductor at the determined amount of thermal conductor, and inserting the cell module into the receiving compartment,
wherein the topography is recorded relative to an imaginary bottom center plane,
wherein the amount to be applied locally is calculated based on a distance between a local bottom position derived from the recorded topography and the imaginary bottom center plane.
