The invention relates to the technical field of batteries or storage batteries, and particularly provides a vehicle feed early warning method and device and a storage medium, and the method comprises the following steps: obtaining the battery capacities of a storage battery and a power battery after receiving a trigger signal; obtaining effective capacity coefficients of the storage battery at different temperatures; obtaining the charging time required by charging of the storage battery in the intelligent charging range under the different temperatures; on the basis of the charging time, the battery capacities of the storage battery and the power battery, the effective capacity coefficient and a preset calibration parameter of a vehicle, determining the early warning time of feed of the storage battery; and when the early warning time is less than a specified duration, giving out an early warning prompt. Through a series of class logic processing, signal acquisition, signal transmission and data display, the time when the whole vehicle is about to be fed is finally estimated, and a vehicle owner is reminded to charge in time through screen display, so that the risk that the vehicle is fed is greatly reduced.

    本发明涉及电池或蓄电池技术领域,具体提供一种车辆馈电预警方法、装置及存储介质,方法包括以下步骤:在接收到触发信号后,获取蓄电池和动力电池的电池容量;获取在不同温度下所述蓄电池的有效容量系数;获取所述蓄电池在所述不同温度下的智能补电范围补电需要的补电时间;基于所述补电时间、所述蓄电池和动力电池的电池容量、所述有效容量系数和预设车辆的标定参数确定所述蓄电池发生馈电的预警时间;当所述预警时间低于指定时长时,发出预警提示。本发明通过一系类逻辑处理、信号采集、信号发送和数据显示,最终预估出整车即将发生馈电的时间,并通过屏幕显示提醒车主及时充电,从而极大降低车辆发生馈电的风险。
