The invention discloses a power battery charging remaining time estimation method and device and an electric vehicle. The method comprises the following steps: acquiring a first charging duration anda second charging duration of the power battery, wherein the first charging duration is the charging duration of the power battery in the heating period, the power battery is in a heating state and acharging state at the same time in the first charging duration, the second charging duration is the duration from an electric quantity at the end of charging of the power battery in the heating periodto a full charge state of the power battery, and the power battery is only in the charging state in the second charging duration; and estimating the charging remaining time of the power battery by adopting the first charging duration and the second charging duration. According to the invention, the technical problem that the finally determined actual charging time and the charging remaining timedisplayed at the beginning of charging have a large error due to the fact that the influence of temperature change on current change is ignored in a power battery charging remaining time estimation mode provided in related technologies is solved.

    本发明公开了一种动力电池充电剩余时间估算方法、装置及电动汽车。该方法包括:获取动力电池的第一充电时长与第二充电时长,其中,第一充电时长为动力电池在加热时段的充电时长,动力电池在第一充电时长内同时处于加热状态和充电状态,第二充电时长为动力电池从加热时段充电完成时的电量至动力电池处于电量充满状态所经历的时长,动力电池在第二充电时长内仅处于充电状态;采用第一充电时长与第二充电时长估算动力电池的充电剩余时间。本发明解决了相关技术中所提供的动力电池充电剩余时间估算方式忽略了温度变化对电流变化所造成的影响,从而导致最终确定的实际充电时间与充电起始显示的充电剩余时间存在较大误差的技术问题。
