    摘要: A battery pack includes a first battery module level and a second battery module level. The first battery module level includes: a first heat exchanger including a cooling tube that defines a cooling area; a first secondary battery cell in thermal contact with the first heat exchanger at the cooling area; a coolant distributor line outside the first heat exchanger and configured to supply coolant to the cooling tube; a coolant interconnector fluidly connecting the cooling tube or the coolant distributor line to the second battery module level; and an encapsulation element enclosing the coolant interconnector and confining a volume in which the coolant interconnector is arranged between the first battery module level and the second battery module level.

    摘要: A battery system includes: a plurality of monolithic cell trays configured to accommodate a plurality of aligned battery cells; a plurality of battery cell retainers configured to retain the battery cells within the cell tray by being connected with the battery cell and the cell tray in each cell tray; a cap-type battery system carrier configured to accommodate the plurality of cell trays; a plurality of tray fasteners provided in each cell tray to mount the cell tray to the battery system carrier by being connected with the cell tray and the battery system carrier; and a cooling channel provided in the battery system carrier to cool the battery cells. Each cell tray includes an opening that exposes the plurality of battery cells, and the cooling channel may be provided in the battery system carrier opposite to the opening of each cell tray.
