The invention relates to the technical field of batteries, and concretely relates to a battery pack with a thermal runaway signal detection function. The battery pack comprises a battery pack body, aflow guide assembly and a plurality of sensors; the flow guide assembly comprises a heat insulation sheet and flow guide pieces, the heat insulation sheet and the flow guide pieces are of an integrated structure, and the flow guide pieces are arranged at the bottom of the heat insulation sheet; the heat insulation sheet is arranged on the battery pack body; and the plurality of sensors are arranged at the periphery of the heat insulation sheet, and at least two sensors are arranged at the end parts of the flow guide pieces. By means of the flow guide assembly and the multiple sensors, no matter where thermal runaway happens to batteries in the battery pack, and gas with a certain gas flow speed can be rapidly guided to the positions of the sensors along the gas flow channels between the flow guide pieces, so thermal runaway signals are rapidly detected and reported to a whole vehicle, passengers are reminded to evacuate, and the safety of passengers is guaranteed.
本发明涉及电池技术领域,尤其涉及一种具有探测热失控信号功能的电池包,其包括:电池包本体、导流组件和多个传感器;所述导流组件包括隔热片和导流件,所述隔热片和所述导流件为一体式结构,所述导流件设于所述隔热片的底部;所述隔热片设于所述电池包本体上;多个所述传感器设于所述隔热片的周边,其中至少两个所述传感器设于所述导流件的端部。通过本发明设置的导流组件和多个传感器,无论电池包内任何地方的电池发生热失控,能够让具有一定气流速度的气体顺着导流件之间的气流通道快速引流至传感器位置,从而快速探测热失控信号并将热失控信号上报报警信息给整车,以提醒乘员疏散,保证乘员的安全。
