The invention discloses a charging remaining time display method and device, and the method comprises the steps: obtaining a battery temperature, an environment temperature, a current battery SOC, and a target charging SOC inputted by a user; according to the battery temperature, the environment temperature, the current battery SOC and the target charging SOC, first remaining time is determined; according to the current battery SOC and the target charging SOC, second remaining time for terminal correction is determined; and controlling the display of the charging remaining time according to the first remaining time and the second remaining time. Thus, by monitoring the environment temperature, the battery temperature and thermal management and comprehensively considering various charging influence factors, the accuracy of the battery charging remaining time is effectively improved, and the display of the charging remaining time can be rapidly adjusted based on the working condition change.

    本发明公开一种充电剩余时间显示方法及装置,通过一种充电剩余时间显示方法及装置,获取电池温度、环境温度、当前电池SOC以及用户输入的目标充电SOC;根据电池温度、环境温度、当前电池SOC以及目标充电SOC,确定第一剩余时间;根据当前电池SOC、目标充电SOC,确定用于末端修正的第二剩余时间;根据第一剩余时间、第二剩余时间,控制充电剩余时间的显示。如此,通过对环境温度、电池温度、热管理的监控,综合考虑多种充电影响因素,有效的提高电池充电剩余时间的准确性,并能够基于工况变化,迅速调整充电剩余时间的显示。
