The invention discloses a charging remaining time prediction method and device and a medium, and the method comprises the steps: obtaining a battery initial temperature and a battery initial SOC of a charging time period, and a historical battery temperature and a historical battery SOC corresponding to a current switching point for each charging time period, determining a first charging time required for the battery starting temperature to reach the historical battery temperature, determining a second charging time required for the battery starting SOC to reach the historical battery SOC, and taking the smaller one of the first charging time and the second charging time as a predicted charging time of the charging period, the current switching point is a node where the charging current corresponding to the charging period is switched; and obtaining the charging end time, and determining the remaining charging time according to the charging end time and each predicted charging time. According to the technical scheme provided by the invention, the accuracy of charging remaining time prediction can be improved.
