1. A flexible printed circuit board bending apparatus for battery cells, the flexible printed circuit board bending apparatus comprising:
a die comprising a horizontal body and a support wall configured to receive a battery cell having a flexible printed circuit board exposed outwards from one side of the battery cell;
a bending guide unit located at one side of the die; and
a bending unit located at the one side of the die,
wherein the bending unit comprises:
a stationary body having an elongated shape with a first end and a second end that is distal to the first end;
a turning body having an elongated shape and rotatably connected to the stationary body at a location adjacent the first end, the turning body being configured to be turnable by a predetermined first angle;
a board seating portion connected to the turning body at the location adjacent the first end, the board seating portion having a board seating groove formed therein, and being configured to receive the flexible printed circuit board, and
a turning shaft extending through the stationary body at the location adjacent the first end, and having a first side connected to the turning body and a second side connected to the board seating portion.
