The invention provides an electric vehicle charging control method and device, and an electric vehicle. The method comprises steps of the first time needed when a vehicle runs to a charging pile arranged by a vehicle-mounted navigation system being calculated; detecting the temperature of the battery, and judging whether the temperature of the battery needs to be controlled or not; after it is determined that the temperature of the battery needs to be controlled, second time needed for adjusting the temperature of the battery to the preset temperature interval being calculated; and calculating a time difference value between the first time and the second time, and determining a moment for starting temperature control on the battery according to the time difference value. According to the charging control method for the electric automobile, the battery pre-charging temperature can be adjusted in winter and summer, it is guaranteed that the electric automobile can be charged at the maximum charging rate in the all-weather environment, the charging time of the electric automobile is shortened, the charging waiting time of a user is shortened, meanwhile, energy consumption in the battery temperature control process is reduced, and the experience feeling of the user is greatly improved.
