The invention discloses a lithium battery management method and system, which is applied to a running vehicle in a flameout state within a period of time interval, and the method comprises the steps: obtaining the working voltage, the working current, the real-time electric quantity and the environment temperature of a lithium battery pack, and converting the working voltage, the working current, the real-time electric quantity and the environment temperature into corresponding binary data; integrating the binary data into a fifth 8 * 4 matrix and a sixth 8 * 4 matrix; jointly inputting the fifth matrix and the sixth matrix into a neural network model for prediction, and generating an output result representing whether the lithium battery pack has electric leakage or not; and under the condition that the lithium battery pack is judged to have electric leakage, electrically connecting the storage module between the lithium battery pack and the load so as to store the electric energy of the lithium battery pack to the storage module. Through the above steps, under the condition that the prediction result is electric leakage, the storage module is controlled to receive the residual electric energy of the lithium battery pack, so that subsequent vehicles can normally run.

    本发明公开了一种锂电池的电池管理方法及系统,应用于在一段时间间隔内处于熄火状态的行驶车辆,方法包括:获取锂电池组的工作电压、工作电流、实时电量和环境温度并将其转换为对应的二进制数据;将上述二进制数据整合成8*4的第五矩阵和第六矩阵;将第五矩阵和第六矩阵共同输入至神经网络模型中进行预测,生成表征锂电池组是否存在漏电的输出结果;在判定锂电池组存在漏电的情况下,将存储模块电连接于锂电池组与负载之间,以将锂电池组的电能存储至存储模块。通过上述步骤,使得在预测结果为漏电的情况下,控制存储模块来接收锂电池组的剩余电能,以便后续车辆可正常行驶。
