摘要： The present application relates to an electric connection assembly for a battery module, a battery module and a vehicle. The electric connection assembly includes a plurality of electrical connection bodies corresponding to a plurality of cell groups of the battery module in a one-to-one relationship, and configured to electrically connect the plurality of the cell groups, wherein, the cell group includes a plurality of single cells, an anode electrode and a cathode electrode of the single cell are arranged on a same one side thereof, the electrical connection body is provided with a plurality of electrical connection portions respectively connected with the electrodes of the plurality of the single cells; each of a plurality of conductive portions is formed between adjacent electrical connection portions, and the plurality of conductive portions of the electrical connection body have a same length and a same cross-sectional area taken along a direction perpendicular to a length direction. Embodiments of the present application provide the plurality of conductive portions with the same length and the same cross-sectional area taken along the direction perpendicular to the length direction, so that the plurality of conductive portions of each electrical connection body have same internal resistances, and thus each single cell has same voltage. As a result, this lowers voltage difference between the single cells, and reduces workload of information processing of BMS and workload of backend detection.

摘要： The present invention relates to a battery module. The battery module comprises at least a first battery cell, a second battery cell arranged in a first direction with respect to the first cell, and a third battery cell arranged in a second direction with respect to the first cell. The battery module also comprises a first interconnection arranged at least partially in the first direction and a second interconnection arranged at least partially in the second direction. The first interconnection is configured to connect the first battery cell and the second battery cell in parallel and the second interconnection is configured to connect the first battery cell and the third battery cell in series. Either the battery cells are aligned along a line in the second direction (y-axis), and immediate neighbouring battery cells in the first direction (x-axis) are disposed in a zig zag pattern in the plane defined by the first direction and the second direction. Or the battery cells are aligned along a line in the first direction (x-axis), and immediate neighbouring battery cells in the second direction (y-axis) are disposed in a zig zag pattern in the plane defined by the first direction and the second direction.
