Abstract
A method and control arrangement for monitoring coating quality during production of electrodes of secondary cells. The production of electrodes comprises a coating process including coating slurry onto a conductive substrate and drying the coated conductive substrate, and a calendering process. The method comprises measuring (S), during the coating process and/or calendering process, power consumption of one or more electrical components used for performing the coating process and/or calendering process and evaluating (S) the coating quality by analyzing the measured power consumption using coating quality criteria, wherein the coating quality criteria defines coating quality of the secondary cells based on measured power consumption of the one or more electrical components.
