The invention provides an electric quantity loss evaluation method and device, electronic equipment and a storage medium, and belongs to the technical field of automobiles, and the method comprises the steps: for a target power-off scene, according to different electric quantity consumption stages after a vehicle is powered off, carrying out the sampling of a quiescent current after the vehicle is powered off, obtaining a plurality of instantaneous quiescent currents corresponding to each power consumption stage; for each power consumption stage, determining a corresponding effective quiescent current according to the plurality of instantaneous quiescent currents corresponding to the power consumption stage; according to each effective quiescent current and the duration of each electric quantity consumption stage, determining electric quantity loss generated by the vehicle in the maximum parking time of the target power-off scene; and according to the electric quantity loss, performing power-off electric quantity consumption evaluation on the vehicle. In this way, multiple instantaneous quiescent currents are collected in each electricity consumption stage, the accuracy of electricity consumption evaluation is improved, the problem that the storage battery is lack of electricity in advance is prevented, and the user experience is optimized.

    本申请提供了一种电量损耗评估方法、装置、电子设备和存储介质,属于汽车技术领域,该方法包括:对于目标下电场景,根据车辆下电后的不同的电量消耗阶段,对车辆下电后的静态电流进行采样,得到每个电量消耗阶段对应的多个瞬时静态电流;对于每个电量消耗阶段,根据电量消耗阶段对应的多个瞬时静态电流,确定对应的有效静态电流;根据每个有效静态电流和每个电量消耗阶段的持续时长,确定车辆在目标下电场景的最大停放时间内产生的电量损耗;根据电量损耗,对车辆进行下电电量消耗评估。这样在每个电量消耗阶段采集多个瞬时静态电流,提高了电量消耗评估的准确性,防止了蓄电池出现提前亏电的问题,优化了用户体验。
