The invention discloses a vehicle battery pack bottom collision detection system, method and device, and relates to the technical field of automobiles. The system comprises a power supply, a first resistor module, a second resistor module, a plurality of plug-in comb tooth type metal conductors, a plurality of third resistor modules and a controller. The method comprises the following steps: acquiring voltages at two ends of the second resistor module; if the voltage at the two ends of the second resistor module is smaller than the reference voltage, bottom collision of the battery pack can be judged; if the voltage at the two ends of the second resistor module is equal to the reference voltage, judging that the battery pack does not have bottom collision; the detection of the bottom collision problem of the battery pack is realized.

    本发明公开了车辆电池包底部磕碰检测系统、方法及装置,涉及汽车技术领域。所述系统包括包括电源、第一电阻模块、第二电阻模块、多个对插梳齿式金属导体、多个第三电阻模块和控制器,所述方法获取第二电阻模块两端的电压;若第二电阻模块两端的电压小于参考电压,则可以判断电池包发生底部磕碰;若第二电阻模块两端的电压等于参考电压,则判断电池包未发生底部磕碰;实现了电池包底部磕碰问题的检测。
