The invention provides a lithium battery pack collision control method which comprises the steps: when a sensor signal processor receives a vibration signal detected by a vibration sensor assembly, the vibration signal is converted into a corresponding displacement amount; the sensor signal processor compares the displacement amount with a plurality of preset standard values; when the displacement amount is greater than the standard values, the sensor signal processor generates a corresponding control signal according to the displacement amount and transmits the control signal to a BMS; and the BMS converts the control signal into a corresponding control instruction and transmits the control instruction to a VCU, and the VCU adjusts the state of the vehicle according to the control instruction. According to the method, the vehicle can detect the collision degree of the lithium battery pack in real time and take corresponding early warning and measures in time, the use safety of the lithium battery pack is guaranteed, and the safety, stability and durability of the whole vehicle are correspondingly improved.

    本发明提供了一种锂电池组碰撞控制方法,当传感器信号处理器接收到振动传感器组件检测到的振动信号时,将振动信号转换成对应的位移量;传感器信号处理器将位移量与预设的若干标准值相比对;当位移量大于标准值时,传感器信号处理器根据位移量生成对应的控制信号,并将控制信号传输至BMS;BMS将控制信号转换成对应的控制指令并将控制指令传输至VCU,VCU根据控制指令调整车辆的状态。该方法使车辆能够实时检测到锂电池组的碰撞程度并及时作出相应的预警及措施,保障了锂电池组的使用安全性,并相应提高了整车的安全性、稳定性以及耐久性。
