The invention discloses a residual charging duration determination method and device, equipment and a storage medium, and relates to the technical field of vehicles, and the method comprises the steps: determining a k-stage charging current according to a k-stage electric quantity value, a k-stage highest temperature, a k-stage lowest temperature and a first mapping relation; according to the k-stage temperature change rate, the k + 1-stage temperature threshold and the k-stage temperature value, the k-stage temperature change duration is determined, and according to the k-stage charging current, the k + 1-stage electric quantity threshold and the k-stage electric quantity value, the k-stage charging duration is determined; determining the minimum value of the k-stage temperature change duration and the k-stage charging duration as the k-stage residual charging duration; according to the k-stage residual charging duration, the k-stage charging current and the k-stage electric quantity value, determining a k + 1-stage electric quantity value; and if the electric quantity value of the (k + 1) stage reaches the target electric quantity threshold value, determining the sum of the residual charging duration of each stage as the residual charging duration. The method can improve the accuracy of the prediction result of the residual charging duration.

    本申请公开了一种剩余充电时长的确定方法、装置、设备及存储介质,涉及车辆技术领域,包括:根据k阶段电量值、k阶段最高温度、k阶段最低温度以及第一映射关系,确定k阶段充电电流;根据k阶段温变速率、k+1阶段温度阈值和k阶段温度值,确定k阶段温变时长,根据k阶段充电电流、k+1阶段电量阈值和k阶段电量值,确定k阶段充电时长;确定k阶段温变时长和k阶段充电时长中最小值为k阶段剩余充电时长;根据k阶段剩余充电时长、k阶段充电电流以及k阶段电量值,确定k+1阶段电量值;如果k+1阶段电量值达到目标电量阈值,则将各个阶段剩余充电时长之和,确定为剩余充电时长。该方法能够提高剩余充电时长的预测结果的准确性。
