The invention relates to the technical field of automobile power batteries, in particular to a low-electric-quantity early warning method of a vehicle-mounted battery, a storage medium and equipment. The low electric quantity early warning method comprises the steps that monitoring information about vehicle-mounted batteries of a vehicle and attribute information of the vehicle-mounted batteries are acquired based on cloud big data, and the vehicle-mounted batteries comprise a high-voltage battery and a low-voltage battery; according to the monitoring information about the vehicle-mounted battery of the vehicle and the attribute information of the vehicle-mounted battery, predicting the residual electric quantity of the vehicle-mounted battery; and when the residual electric quantity of the high-voltage battery or the residual electric quantity of the low-voltage battery is lower than a preset threshold value, outputting early warning information of low electric quantity. According to the invention, the residual electric quantity of the high-voltage battery and the low-voltage battery is predicted based on the cloud big data, the electric quantity of a vehicle without communication for a long time is predicted, and irreversible damage caused by vehicle breakdown and battery over-discharge due to long-term parking of the vehicle is avoided.

    本发明涉及汽车动力电池技术领域,特别是涉及一种车载电池的低电量预警方法、存储介质与设备。该低电量预警方法包括:基于云端大数据获取所述车辆关于车载电池的监控信息以及所述车载电池的属性信息,其中,所述车载电池包括高压电池和低压电池;根据所述车辆关于车载电池的监控信息以及所述车载电池的属性信息,预测所述车载电池的剩余电量;在所述高压电池的剩余电量或所述低压电池的剩余电量低于预定阈值的情况下,输出低电量的预警信息。本发明基于云端大数据预测高压电池和低压电池的剩余电量,实现了对长期无通讯的车辆做电量预测,避免了由于车辆长期停放导致的车辆抛锚和电池过放电导致的不可逆损伤。
