The invention belongs to the technical field of electric quantity management, and discloses a fast charging remaining time estimation method and device, equipment and a storage medium. According to the method, the initial battery pack temperature is obtained, the temperature rise calculation strategy is determined, the charging amount and the estimated time of the stage are obtained through calculation, the total charging amount of the quick charging timing stage is determined by combining the real-time battery pack remaining electric quantity, and the charging rate is calculated according to the temperature charging rate corresponding graph and the preset unit charging amount. Calculating the estimated time of each unit charging amount, accumulating the estimated time, and determining the estimated time of a tail end stage according to the parameters of the charging pile; and summarizing the pre-estimated time of the plurality of stages, determining the total pre-estimated time, displaying the total pre-estimated time on an instrument, and adjusting the time drop rate of the actually displayed total pre-estimated time according to a numerical value calculated in real time by a program. According to the method, the influence of the temperature change, the charging amount and the charging rate on the charging time in the charging process is comprehensively considered, the displayed estimated time is dynamically adjusted, and accurate charging remaining time estimation is provided.

    本发明属于电量管理技术领域,公开了一种快充充电剩余时间估计方法、装置、设备及存储介质。本发明通过获取初始电池包温度,确定升温计算策略,计算得到该阶段的充电量与预估时间,结合实时电池包剩余电量,确定快充计时阶段的总充电量,依照温度充电速率对应图与预设单位充电量,计算每个单位充电量的预估时间并进行累加,根据充电桩参数,确定末端阶段预估时间;将多个阶段的预估时间进行汇总,确定总预估时间,并将总预估时间显示在仪表上,实际显示的总预估时间按照程序实时计算的数值调整时间下降速率。本发明综合考虑充电过程中温度变化、充电量和充电速率对充电时间的影响,并动态调整显示的预估时间,提供准确的充电剩余时间估计。
