The invention relates to a power battery charging method and device and a vehicle. The method comprises the steps that in the charging process of a power battery, the temperature of the power battery is acquired; in a plurality of preset temperature intervals, determining a target temperature interval to which the temperature of the power battery belongs; and controlling the power battery to charge according to a preset charging cooling strategy corresponding to the target temperature interval. Therefore, charging control adaptive to the real-time temperature can be implemented on the power battery by pre-determining the target temperature interval and the control strategy corresponding to the target temperature interval, so that various problems caused by the high temperature of the power battery during charging are avoided, the problem of slow dynamic response of the vehicle caused by the high temperature of the power battery during temporary vehicle use by a user is avoided, and the user experience is improved. And meanwhile, the charging efficiency is also considered.
本公开涉及一种动力电池充电方法和装置、车辆。所述方法包括:在动力电池充电的过程中,获取所述动力电池的温度;在预定的多个温度区间中,确定所述动力电池的温度所属的目标温度区间;依据预设的与所述目标温度区间对应的充电降温策略,控制所述动力电池进行充电。这样,能够通过预先确定目标温度区间及其对应的控制策略,对动力电池实施与实时温度相适应的充电控制,以避免在充电时动力电池的温度较高带来的各种问题,避免用户临时用车时,由动力电池高温导致的车辆动态响应慢的问题,同时也兼顾了充电效率。
