The invention provides a residual charging time estimation method and device, a storage medium and a vehicle, and belongs to the technical field of charging. According to the embodiment of the invention, the charging process of the battery is divided into n charging stages; determining a charging current corresponding to each charging stage according to the initial SOC value and the initial battery temperature of each charging stage; estimating the estimated charging time of each charging stage based on the charging current corresponding to each charging stage; and finally, based on the heating time of the battery and the estimated charging time of the n charging stages, determining the residual charging time of the battery. According to the embodiment of the invention, while the heating time of the battery is considered, the initial battery temperature corresponding to each charging stage participates in the calculation of the residual charging time, and the influence of the temperature condition of each charging stage on the residual charging time is fully considered, so that the accuracy of the estimated residual charging time is improved, and the calculation efficiency is improved. A more accurate reference can be provided for power utilization of a user, and the user experience is improved.
本申请提供了一种剩余充电时间估算方法、装置、存储介质和车辆,属于充电技术领域。本申请实施例将电池的充电过程划分为n个充电阶段;根据每个充电阶段的起始SOC值和起始电池温度,确定每个充电阶段对应的充电电流;再基于每个充电阶段对应的充电电流,预估每个充电阶段的预估充电时间;最后基于电池的加热时间和n个充电阶段的预估充电时间,确定电池的剩余充电时间。本申请实施例在考虑电池的加热时间的同时,通过将每个充电阶段各自对应的起始电池温度参与到剩余充电时间的计算中,充分考虑到了每个充电阶段的温度状况对剩余充电时间的影响,进而提升估算的剩余充电时间的准确性,能够为用户用电提供更为准确的参考,提升用户体验。
