    摘要： A secondary cell (10) is disclosed, comprising a first end plate (131) and a second end plate (132). The first end plate comprises a contacting tab (121) configured to provide an electrical contact between a first electrode of an electrode assembly and a first terminal, as well as a first spacer arrangement (134) arranged between the first end plate and the electrode assembly and configured to secure the electrode assembly in a length direction. The second end plate comprises a current collector (122) and a second spacer arrangement (144), wherein the second spacer arrangement is arranged to secure the electrode assembly in the length direction and the current collector to secure the electrode assembly in a direction orthogonal to the length direction. A method for assembling such a cell is also disclosed.

    摘要： 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 cells 1 in mass scale production testing. The method comprises obtaining manufacturing data (i.e. data analysis 41) and generating scanning data by scanning 42 an inside of the secondary cells. The method further comprises determining cell quality using a prediction algorithm, performing additional testing 43 on 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 cells 1 based on the cell quality determined using the prediction algorithm. The disclosure also relates to a corresponding control arrangement.

    摘要： An electrode plate assembly for a secondary battery module is disclosed, comprising a plurality of cells (100) arranged in a vertical stack (10). Each cell of the stack comprises a positive electrode plate (110), a negative electrode plate, and a separator. The separator is interposed between the positive electrode plate and the negative electrode plate and configured allow ions to move between the positive electrode plate and the negative electrode plate. The electrode plate assembly further comprises a plurality of contacting means (140) for electrical monitoring of the cells, wherein each of the plurality of contacting means is electrically connected to at least one of the positive and negative electrode plates of a respective one of the cells and arranged to protrude laterally from a side edge (101, 102, 103) of the cell. The contacting means are distributed spatially along a width (W) of the stack.
