POWER SUPPLY SYSTEM OF VEHICLE, APPARATUS AND METHOD OF THE SAME

摘要

PURPOSE: A vehicle power supply system, apparatus for the same, and a method thereof are provided to determine charging priorities among users based on the stay time of each user in a certain area, thereby reducing the unnecessary waiting time for charging and to differentiate power rates depending on the purchase history of each user, thereby enabling users to buy power at a low price or to sell power at a high price. CONSTITUTION: Vehicle power supply apparatus receives the stay time data of each user (S101) and determines the vehicle charging priorities based on the received data (S102). According to the determined charging priorities, the vehicle power supply apparatus supplies power to a vehicle (S103) and calculates a charge for the power supplied to the vehicle (S105).
