1. A battery pack, comprising:
a plurality of battery modules, wherein each battery module comprises:
a battery row, comprising a plurality of battery cells arranged in a longitudinal direction, wherein each battery cell comprises two electrodes with opposite polarities, and electrodes of all battery cells of the battery row form two electrode rows arranging in the longitudinal direction;
a flexible printed circuit board, extending in the longitudinal direction and located between the two electrode rows of the battery row; and
two conductive connecting plate rows, located on two sides of the flexible printed circuit board in a transverse direction respectively, wherein each conductive connecting plate row comprises a plurality of conductive connecting plates arranged in the longitudinal direction and spaced apart from each other, and each conductive connecting plate of each conductive connecting plate row is electrically connected to the flexible printed circuit board and electrically connected to a corresponding electrode of a corresponding electrode row;
wherein each battery module further comprises:
an insulation cover, covering and fixed to a top of the battery row to insulate each battery module from outside; and
an insulation batten, extending in the longitudinal direction and fixed onto the flexible printed circuit board,
wherein each insulation cover is fixed onto a corresponding insulation batten, each insulation batten is located above the corresponding flexible printed circuit board, and the flexible printed circuit board is directly fixed to the top of the battery row,
each insulation batten comprises an inner recessed channel extending in the longitudinal direction of the insulation batten,
each insulation cover comprises two positioning slots located on two sides of the insulation cover in the longitudinal direction and recessed inward from side edges of the insulation cover, wherein each positioning slot is aligned with the inner recessed channel of a corresponding insulation batten,
each battery module further comprises: two positioning screws passing through two sides of the inner recessed channel of the insulation batten of the battery module in the longitudinal direction and fixed onto the flexible printed circuit board, wherein a top of each positioning screw protrudes from an upper surface of the insulation batten, and
each positioning screw is engaged with a corresponding positioning slot of the insulation cover to position the insulation cover between corresponding two positioning screws.
