Abstract
The present disclosure provides a battery pack including: multiple flat battery cells, a housing, a bearing plate and an upper cover, wherein a middle recessed portion is formed between the protruding battery cell anode and battery cell cathode disposed on the top portion of each of the multiple battery cells; a surface of the middle recessed portion is provided with at least one seal-breakable opening arranged to discharge the gas generated in the battery cell when broken; the multiple middle recessed portions at the top portions of the multiple battery cells form a battery top portion through-slot; a bottom portion of the bearing plate is provided with a bearing plate bottom portion through-slot; the bearing plate bottom portion through-slot is press-fitted with the battery top portion through-slot to form a lateral gas discharging passage wherein one end of the lateral gas discharging passage is provided with an outlet, and another end of the lateral gas discharging passage is blocked. The gas discharging passage of the present disclosure utilizes the existing structures of the battery pack without additionally designing a separate specific gas discharging passage.
