Abstract
The present disclosure pertains to testing of rechargeable cells for use in batteries arranged in electrical vehicles. According to a first aspect the disclosure relates to method for evaluating cell health of secondary cellsin mass scale production testing. The method comprises obtaining manufacturing data (i.e. data analysis) and generating scanning data by scanningan inside of the secondary cells. The method further comprises determining cell quality using a prediction algorithm, performing additional testingon a selection of the scanned secondary cells and verifying, based on the additional testing, accuracy of the prediction algorithm. The method thereafter comprises evaluating cell health of the individual cellsbased on the cell quality determined using the prediction algorithm. The disclosure also relates to a corresponding control arrangement.
