The invention relates to a battery charging method and device, a medium and a vehicle, and relates to the technical field of charging, and the method comprises the steps: obtaining the single voltage, temperature and state of charge of a battery in the charging process; before the single voltage reaches a protection voltage corresponding to a charge state threshold value, a first target charging rate is determined according to the charge state and the temperature, and the charge state threshold value is determined according to the charge state when the charging safety parameter meets the safety condition; and controlling the battery to be charged at the first target charging rate. Thus, the monomer voltage of the battery is not limited by the protection voltage corresponding to the charge state smaller than the charge state threshold value, and the charging capacity of the battery is higher before the monomer voltage of the battery reaches the protection voltage corresponding to the charge state threshold value. And the state-of-charge threshold is determined according to the state-of-charge when the charging safety parameter meets the safety condition, so that the charging speed of the battery can be improved on the premise of meeting the charging safety of the battery.

    本公开涉及一种电池充电方法、装置、介质及车辆,涉及充电技术领域,方法包括:获取电池在充电过程中的单体电压、温度和荷电状态;在单体电压达到荷电状态阈值对应的保护电压之前,根据荷电状态和温度,确定第一目标充电倍率,荷电状态阈值根据充电安全参数满足安全条件时的荷电状态确定;控制对电池以第一目标充电倍率进行充电。如此,电池的单体电压不会被小于荷电状态阈值的荷电状态所对应的保护电压限制,在电池单体电压达到荷电状态阈值对应的保护电压之前,电池的充电能力更强,而且荷电状态阈值是根据充电安全参数满足安全条件时的荷电状态确定的,因此,本方案可以实现在满足电池充电安全的前提下,提高电池的充电速度。
