The embodiment of the invention provides a battery charging time prediction method, a vehicle, a program product and a storage medium, and the method comprises the steps: determining all target SOC intervals through which charging passes in sequence from a plurality of preset SOC intervals according to the current SOC and the charging cut-off SOC of a target battery; performing prediction processing for each target SOC interval, the prediction processing including: predicting, according to the predicted temperature change rate, a target temperature interval passed by the target battery when the target battery is charged within the target SOC interval; determining a corresponding first calibration charging parameter according to the target SOC interval and the target temperature interval; the charging time in the target SOC interval is predicted based on the first calibration charging parameter; and determining the total charging duration according to the charging time of the target SOC interval. By establishing the corresponding relation among the SOC interval, the temperature interval and the calibrated charging parameter, the charging time prediction including the temperature prediction function is realized, and the accuracy of the charging time prediction in the extreme temperature environment is improved.

    本申请实施例提供一种电池充电时间预测方法、车辆、程序产品及存储介质,所述方法包括:根据目标电池的当前SOC与充电截止SOC,从多个预设的SOC区间中确定充电时依次经过的所有目标SOC区间;针对每个目标SOC区间执行预测处理,所述预测处理包括:根据预测的温度变化速度,预测目标电池在目标SOC区间内充电时经过的目标温度区间;根据目标SOC区间及目标温度区间,确定对应的第一标定充电参数;并基于第一标定充电参数预测在目标SOC区间内的充电时间;根据目标SOC区间的充电时间,确定充电总时长。通过建立SOC区间、温度区间与标定充电参数三者之间的对应关系,实现了包含温度预测功能的充电时间预测,提升了极温环境下充电时间预测的精确度。
