  • Patent number: 12246339
    Abstract: A fixture unit for holding a prismatic battery cell during a coating step and during a curing step, including: at least one skirt element, which is movable between a coating position and a curing position and wherein the skirt element is configured to shield an area of the battery cell in the coating position and to un-shield the area of the battery cell in the curing position; and at least one grip element configured to hold the battery cell during the coating step and the curing step, wherein the grip element is configured to hold the battery cell in the area that is shielded by the skirt element in its coating position.
    Type: Grant

  • Publication number: 20230261304
    Abstract: A battery pack for use in an electric vehicle having two longitudinal sill members extending in a length direction, interconnected at a front side by front and rear transverse members, a number of rectangular battery cells being placed between the sill members, the front transverse member and the rear transverse member, the cells being mutually adjacent in the length direction. The battery pack has at least a chamber integrated in the rear transverse beam, said chamber being configured to accommodate an analog-to-digital converter.

  • Patent number: 11635471
    Abstract: A method of detecting a latent fault of at least one cell among a plurality of cells in an energy storage system, and a control unit performing the method. The method comprises determining State of Health Cell Resistance, SoHCR, and State of Charge, SoC, of a selected cell, wherein the selected cell is indicated to have a latent fault if a determined value of the SoHCR is higher than a reference value and if a determined value of the SoC is higher than a reference value; or determining State of Health Cell Capacity, SoHCC, and State of Charge, SoC, of a selected cell, wherein the selected cell is indicated to have a latent fault if a determined value of the SoHCC is lower than a reference value and if a determined value of the SoC is higher than a reference value.

  • Patent number: 11209493
    Abstract: A method of detecting a latent fault of at least one cell among a plurality of cells in an energy storage system, and a control unit performing the method, are provided. A method of a control unit of detecting a latent fault of at least one cell among a plurality of cells in an energy storage system is also provided. The method comprises determining State of Health Cell Capacity, SoHCC, and Open Circuit Voltage, OCV, of a selected cell; wherein the selected cell is indicated to have a latent fault if a determined value of the SoHCC of the selected cell is lower than a reference value for the SoHCC and if a determined value of the OCV of the selected cell is higher than a reference value for the OCV.
