To meet the flight guarantees and the charging requirements of Civil Aviation Specific Electric Vehicle (CASEV), a charging control strategy is proposed in this paper. Firstly, the relation between the number of real-time flights and the number of CASEV, and the impacts of the number of real-time flights on the critical threshold of electric special vehicle charging power are analyzed. Then, a orderly mathematical model of CASEV charging strategy, which is subjected to the number of flights and charging capacity of the electric vehicle, is established which takes the minimum cost of charging as the objective function. At last, based on the actual operation data from an existing airport electric special vehicle, the charging behaviors of airport electric vehicles under the ordered charging and out-of-order charging strategies are simulated. It is shown that the proposed orderly charging strategy can decrease the impacts on the power supply grid from the charging for CASEV, and also decrease the cost of charging operations.
