<p>The invention provides a battery module. A second fixing case of the battery module includes at least one guide structure and at least one guide hole. The guide structure, in an accommodation space, extends out from a bottom plate of the second fixing case. The guide hole is arranged in the bottom plate, and the positions of the guide hole and the guide structure are in correspondence. A pin of an electrode piece passes through the guide hole, extends along the guide structure, and is electrically connected to a connection pad of a circuit board. As a result, the pin of the electrode piece can be effectively guided, and a free end of the pin can be disposed on the connection pad of the circuit board. By adopting the above design, not only are wires in the prior art omitted, but also electric connection structures and electric connection programs between the circuit board and a plurality of batteries are simplified, so that the production cost is reduced, and working hours for assembling the battery module are saved.</p> |
