Abstract: A method and server for managing mobile rechargeable battery pools of multiple stations, comprising steps of: (a) in a response to a selection of a specific location, the management server displaying pieces of location information on the stations by referring to a current location of the specific user and the specific location; (b) in a response to a selection of a k-th station among the stations, the management server displaying (i) information on (k_1)-st mobile rechargeable batteries available at a current time and (ii) information on (k_2)-nd mobile rechargeable batteries available at an estimated arrival time; and (c) in a response to a selection of a specific k-th mobile rechargeable battery, by the user device for a future need, the management server sending information on the future need to an administrator device or a provider device.

Abstract: A system for operating an electric-vehicle charging station is proposed. The system is capable of preventing a general vehicle other than an electric vehicle from being parked in a parking station where the charging module for charging the electric vehicle is installed, preventing an electric vehicle from being parked in a charging station at a higher level than necessary, and eliminating the need for the driver of a subsequent vehicle to wait for charging in the charging station when there is a vehicle that is in a charging state in the charging station.

Abstract: A method for controlling charging capacity of an electric vehicle charging terminal capable of charging an electric vehicle is provided. The method includes steps of: an electric vehicle charging station, (a) while the electric vehicle charging terminal is connected to the electric vehicle via a charging connector, wherein the electric vehicle charging station manages unit charging sources and includes the electric vehicle charging terminal connected with a grouped charging source created by combining part of the unit charging sources, and wherein capacity of the grouped charging source is dependent on the combined part, selecting unit charging sources to be combined as a grouped charging source by referring to required charging capacity information of the electric vehicle; and (b) (i) controlling switches for connecting the unit charging sources to create the grouped charging source and (ii) allowing the grouped charging source to charge the electric vehicle through the charging connector.
