The invention relates to the technical field of electric automobiles, and discloses a charging control method, a charging control device and an electric automobile. The method comprises the steps that the maximum output voltage value and the actual output voltage value of a charging pile are acquired; acquiring a total rated voltage value and a current voltage value of a power battery of the vehicle; when the total rated voltage value of the power battery is greater than the maximum output voltage value of the charging pile, the current voltage value of the power battery is compared with the actual output voltage value of the charging pile, so that a direct charging loop or a boost charging loop is controlled to be conducted; and the charging pile charges the power battery through the selected loop. According to the charging control method, the electric vehicle and the charging system, charging piles with different output voltage values can be compatible for charging, and the charging efficiency is improved.
