A power charging and selling device includes first and second connection units configured to be connected to an electric vehicle and at least one power supplier server, respectively; a control unit for receiving a unique identifier and battery information of the electric vehicle through the first connection unit and for receiving power-trading charge information provided from each power supplier server through the second connection unit; and a guide unit for advertising the received power-trading charge information and for enabling selection of a corresponding power supplier. Through the first connection unit, the control unit may charge the electric vehicle with the power of a selected power supplier or sell the power stored in the electric vehicle to a selected power supplier. The power charging/selling device receives charge information from power suppliers, and a user selects the charging/selling scheme accordingly, even if the power source of the electric vehicle is turned off.

A system includes a processor configured to receive a vehicle identifier identifying a vehicle from a first digital entity. The processor is also configured to digitally obtain a payment account associated with the identifier, responsive to receiving the identifier. The processor is further configured to validate payment rights through input from a second entity, confirming the right to use the account to pay for charging the vehicle and responsive to successful validation, charge the payment account for vehicle charging, following vehicle charging completion.

An apparatus, a system, and a method are for automatically billing a vehicle left unattended in a charging station. The automatic billing apparatus includes a processor that provides a vehicle charging service at a charging station, determines that a vehicle is unattended after charging is completed, and performs a billing based on an unattended time. The apparatus further includes a storage that stores data obtained by the processor when the billing is performed.

A system for registering power outlets that may be used to charge electric vehicles, personal mobility devices, electrical and electronic devices which includes a database for storing subscriber data relating to subscribers registered with the system and power outlet data relating to registered outlets that have been located by a subscriber. A server for providing a power outlet management system. The server is configured to receive the power outlet data for a power outlet from the subscriber, register the power outlet with the power outlet management system if the power outlet has not previously been registered and store the power outlet data for the power outlets in the database. The server is further configured to receive a search request for a useable power outlet from the subscriber. The search request includes location information defining an area of search for the useable power outlet. The server locates at least one power outlet within the area of search that is registered with the power outlet management system and provides a location of the at least one power outlet located within the area of search to the subscriber. A network interface connects the server to a network for receiving the power outlet data and the search request.

A system for registering power outlets for electric vehicle charging that may be used to charge electric vehicles. A database stores subscriber data relating to subscribers registered with the system and power outlet data relating to registered power outlets for electric vehicle charging that have been located by a reporting entity. A server provides a power outlet management system that receives the power outlet data for a power outlet for electric vehicle charging from the reporting entity, registers the power outlet for electric vehicle charging with the power outlet management system if the power outlet electric vehicle charging has not previously been registered and stores the power outlet data for the power outlet for electric vehicle charging in the database. The server is further configured to receive a search request for a useable power outlet for electric vehicle charging from a subscriber, the search request including location information defining an area of search for the useable power outlet for electric vehicle charging, locate at least one power outlet for electric vehicle charging within the area of search that is registered with the power outlet management system and provide a location of the at least one power outlet for electric vehicle charging located within the area of search to the subscriber. A network interface for connecting the server to a network for receiving the power outlet data and the search request.

A method for access control accepts a first data from a first mobile computing device of a first patron. The first data is representative of at least a certificate and represents an authorization for access. The method further provides the access in response to the first data, and makes a record in the first station. The record includes a second data representing the access and an identifying portion of the certificate. The method further provides, after the access, a third data to a second mobile computing device of any patron. The third data is deliverable by the second mobile computing device to the management system and is representative of the record. The method further accepts a fourth data that is representative of at least an acknowledgment of the record, and deletes the record from the first station in response to the fourth data.

A strong unsolved need exists to provide people with breathable gases for inhaling instead of ambient air, when people live in areas, where the ambient air is polluted with toxic gases and particulate matters. The present invention solves this need by disclosing a breathing apparatus, a dispenser of breathable gases, and a distributor of breathable gases, for supplying breathable gases to people, exposed to polluted and contaminated outdoor and indoor ambient air.
