It should be noted that, in the present invention, the length, the height and the width of the battery cell casing, the length, the width and the height of the pole group 30 are all related to the placement mode of the battery cells, that is, the direction in which the height is consistent with the height direction of the vehicle, when the battery cells are stacked in sequence in the length direction of the mounting base 10, the direction in which the length is consistent with the left-right direction of the vehicle, and the direction in which the thickness is consistent with the front-rear direction of the vehicle; when the battery cells are stacked in sequence in the width direction of the battery cells, the direction in which the length is positioned is consistent with the front-rear direction of the vehicle, and the direction in which the thickness is positioned is consistent with the width direction of the vehicle.
