The invention discloses a charging protection method and device in a fast charging mode and a storage medium. The method comprises the following steps: acquiring the initial electric quantity of a target battery; when the initial electric quantity is lower than the preset electric quantity, a target fast charging mode corresponding to the target battery is determined, and the target fast charging mode corresponds to the initial fast charging power; the method comprises the following steps: carrying out fast charging on a target battery with initial fast charging power through charging equipment in a target fast charging mode; acquiring target charging current data of the target battery in a preset time period; determining a maximum current value in the target charging current data to obtain a first current value; when the first current value is not in the first preset current range, determining a target abnormal probability of the target battery according to the target fast charging mode and the target charging current data; adjusting the initial fast charging power according to the target abnormal probability to obtain target fast charging power; and controlling the charging equipment to quickly charge the target battery with the target quick charging power. By adopting the embodiment of the invention, the safety of quick charging of the battery is improved.

    本申请公开了一种快充模式下的充电保护方法、装置及存储介质,该方法包括:获取目标电池的初始电量;在初始电量低于预设电量时,确定目标电池对应的目标快充模式,目标快充模式对应初始快充功率;通过充电设备在目标快充模式下,以初始快充功率为目标电池进行快充充电;获取预设时间段内目标电池的目标充电电流数据;确定目标充电电流数据中的最大电流值,得到第一电流值;在第一电流值不处于第一预设电流范围时,根据目标快充模式和目标充电电流数据确定目标电池的目标异常概率;根据目标异常概率调整初始快充功率,得到目标快充功率;控制充电设备以目标快充功率为目标电池进行快充。采用本申请实施例,提升了电池快充的安全性。
