The utility model discloses a short-circuit protection structure for a battery pack wire harness. The short-circuit protection structure comprises a nickel sheet body connected with a battery pack, the nickel sheet body is provided with a plurality of spot welding grooves and a connecting lug, wherein one end of the connecting lug extends out and is connected with an acquisition wire harness. The connecting lug comprises a wire harness welding platform and an over-current fusing arm; the over-current fusing arm has a safe state and a fusing state, and when the over-current fusing arm is in the safe state, the output current of the battery pack is transmitted to an acquisition wire harness through the over-current fusing arm; and when the battery pack is in the fusing state, the output current of the battery pack fuses the over-current fusing arm, so that the over-current fusing arm is disconnected. According to the utility model, the over-current fusing arm is arranged on the wiring harness welding platform,
