The invention discloses a vehicle storage battery state monitoring method and system, and the method comprises the steps: carrying out the timing of a vehicle control stage through a vehicle body controller, and collecting a voltage signal and a current signal of a storage battery corresponding to the control stage, converting the voltage signal of the storage battery into a corresponding state of charge (SOC) value according to a preset corresponding relationship between the SOC of the storage battery and the voltage of the storage battery at different temperatures; enabling the vehicle body controller to upload a charge SOC signal of the storage battery, a current signal of the storage battery and a timing signal in the control stage to a background server; enabling the background server to calculate the change rate of the state of charge (SOC) of the storage battery in unit time, enabling the background server to judge whether the change rate of the state of charge (SOC) of the storage battery in unit time in the control stage is larger than a preset SOC change rate threshold value or not, and if yes, marking and storing the information that the storage battery is lack of electricity in the control stage. According to the method, big data processing and analysis are carried out through the background server, and whether power shortage occurs in the whole vehicle control stage or not can be monitored.
本发明公开一种车辆蓄电池状态监测方法及系统,步骤包括:车身控制器对车辆控制阶段进行计时并采集控制阶段对应的蓄电池的电压信号和电流信号,将蓄电池的电压信号根据预先设定的不同温度下蓄电池的荷电状态SOC和蓄电池电压的对应关系转化成对应的荷电状态SOC值;车身控制器将该控制阶段内的蓄电池的荷电SOC信号、蓄电池的电流信号和计时信号上传给后台服务器;后台服务器计算单位时间内蓄电池的荷电状态SOC的变化率,后台服务器判断控制阶段单位时间内蓄电池的荷电状态SOC的变化率是否大于预设SOC变化率阈值,若是,则标记和保存该控制阶段内蓄电池发生亏电的信息。该方法将通过后台服务器进行大数据处理和分析,能够监测整车控制阶段是否到发生亏电。
