The invention discloses a new energy automobile storage battery intelligent monitoring method, which comprises the following steps of: monitoring and collecting the parking time of the automobile in real time after the automobile stalls; starting a BMS to detect the storage battery and a power battery when the parking time is greater than a set time threshold value; and determining whether to start an intelligent charging policy or not according to a detection result. The new energy automobile storage battery intelligent monitoring method has the advantages that the automobile storage battery and the automobile parking time can be monitored in real time, the BMS is started through the monitored parking time, the voltage of the storage battery and the SOC of the power battery to conduct an intelligent charging policy, and starting of intelligent charging is achieved more reasonably and reliably; the intelligent charging policy fully considers the conditions of controller faults, automobile starting in the charging process, abnormal voltage, current and temperature parameters in the charging process and the like, and can stop charging in time, and therefore the reliability and safety of charging are improved, and charging of the storage battery of the automobile is achieved on the premise that safety and reliability are guaranteed.

    本发明公开了一种新能源汽车蓄电池智能监控方法,在车辆熄火静止后,实时监控采集车辆停车静止时间,当停车静止时间大于设定时间阈值时,启动BMS对蓄电池和动力电池进行检测,根据检测结果确定是否启动智能补电策略。本发明的优点在于:可实时监控车辆蓄电池、车辆停车时间,通过监控的停车时间、蓄电池电压、动力电池SOC来启动BMS进行智能补电策略,更加合理可靠的实现智能补电的启动;补电策略充分考虑控制器故障、补电过程中车辆启动、补电过程中电压电流温度参数异常等情况,可以做到及时停止补电,从而提升补电的可靠性和安全性,在保证安全可靠的前提下实现对于车辆的蓄电池的补电。
