[0033] Based on the above structure, the present application sets the PCM board 2 flat on the XY plane at an angle. Compared with the arrangement scheme perpendicular to the YZ plane, the PCM board 2 set at an angle can reduce its occupancy in the X direction; further, compared with the arrangement scheme perpendicular to the XY plane, the PCM board 2 set at an angle can reduce its occupancy in the Z direction, that is, the PCM board 2 of the present application can compromise the above two arrangement schemes, thereby reducing its space occupancy in the X direction and the Z direction at the same time, thereby freeing up space for the arrangement of the battery cell 1, so that the battery cell 1 can increase the design size in at least one direction of the X and Z directions to achieve an increase in battery capacity.
