The invention provides an economical electric vehicle charging control method capable of combining power grid time-sharing charging and the car-using requirement of a user. The economical electric vehicle charging control method can effectively save the charging control cost and relieve the burden of a local power grid. The economical electric vehicle charging control method includes the following steps that A: a charging gun is inserted; whether a battery management system (BMS) goes into an economical charging mode or not is selected according to user settings, if yes, the step B is carried out; if not, normal charging is carried out; B: the economical charging mode is carried out; a user sets the car using time and mileage; the BMS works out whether the capacity of charging enough to the electricity use mileage is achieved or not from the current time to the car use time set by the user and during an electricity use low-peak period; if yes, charging is carried out during the electricity use low-peak period; if the charging gun is inserted during the electricity use high-peak period, charging is delayed to the electricity use low-peak period; if the charging gun is inserted during the electricity use low-peak period, charging is directly carried out; if not, the electricity energy difference is worked out and made up during the electricity use high-peak period.
