PURPOSE: A method of allotting dynamic priority for charging an electric car in a large scale charging station is provided to minimize the time required to charge the car by charging the car in public housing, a multipurpose building and a large scale parking lot of a building. CONSTITUTION: The input section of a charging terminal receives the charge information including input time, departure time and charging amount information. A plurality of cars is prioritized. The cars are charged in order of the priority. A power supply device checks the number of cars to be charged according to the charge information from each electric car. When the number of cars is over zero(S10), the car is prioritized in order of the size of the demand power ratio of each car(S20). The number of chargeable cars is calculated(S30). |
