1. For any vehicle entering the parking a new three part paper ticket is issued All ticket parts carry the same unique bar coded num ber A facility operator or an attendant gives one part of that ticket to a client keeps another part of the ticket in the office and uses the third part for vehicle authorization at the recharg ing station 0078 After moving the car to any recharging station the attendant connects a recharging cable to the station s connec tor and the station generates a request for vehicle ID to be sent to the vehicle s remote ID Device 0079 If the recharging station receives a vehicle ID in response to said request then the station sends this ID to the Central Unit s CVI module for identification If the ID is recognized there as previously authorized the Central Unit sends a command to the station to resume recharging 0080 Ifthe station does not receive any ID from the con nected vehicle remote ID Device or if the received ID is not recognized by CV as previously authorized then the station displays a request to scan a ticket The attendant then scans the ticket and the station receives the ticket number generates anew ID and links this new ID to the obtained ticket number Then the request for authorization data associated with this ticket number is sent to CBM Such authorization data can include authorized by the vehicle operator amount of energy to be used in recharging or the recharging time or the rec2. the Processor 1 implements the ID Generator 11 ID Storage 12 ID Validator 19 ID Comparator 14 Service Authorization module 52 and Billing module 17 0063 The Manual Input Device 2 comprises a number of pushbuttons or equivalent user entry devices e g touch screen buttons for user selection e g 20 kWHr 4 Hrs 10 20 full battery fill up or other similar buttons defining recharging duration This device also includes a Cancel but ton to cancel an entry and a Stop button to manually stop recharging at any moment prior to completion 0064 A Display 6 comprising a number of indicators and or a visual device LED LCD screen and such and connected to the Processor 1 communicates the system mes sages to the user 0065 A Payment Receptor 3 may include a cash receptor a credit card reader a barcode reader and any other device capable of reading an appropriate authorization media It may also include a receipt printer The Payment Receptor 3 is a part of the Service Authorization module 52 0066 A Vehicle Identifier Module 4 implements the ID Requestor 10 and the Communicator 13 0067 A Cable Connector 5 connects to a vehicle recharg ing cable to supply recharging energy from the Power Con troller 7 to the vehicle It also interfaces the Vehicle Identifi cation Module 4 to the Recharging Cable 16 for communication with the Remote ID Device 15 The Cable Connector 5 is equipped with a detector switch to detect wh

8. the following modules can be included a central ID Generator for generating new IDs a central ID Validator for deleting expired IDs and deleting IDs on the recharging complete and the sale closed events This variant of the CVI reflects the idea that a central vehicle identification module will generate store assign and delete all IDs in the network 0074 The Payment Station in the FIG 4 comprises a Pro cessor 40 a Display 46 for providing visual information to the user a Manual Input Device 42 for selecting the amount of energy for recharging and other tasks that require manual input a Payment Receptor 43 such as a cash receptor credit card reader charge card reader or any other payment or billing authorization card reader to pay for services a ticket reader for reading a ticket that linked to the services provided to a vehicle 0075 Other variants of implementation of the network of recharging stations are certainly possible and implied by this invention 0076 Following is the example of network operation while it is understood that other scenarios are possible with out deviating from the scope of the present invention 0077 Upon entering a parking facility a client or a vehicle operator communicates to parking personnel a desired amount of recharging energy or recharging time or payment for recharging or full battery fill up This authorization data Sep 23 2010 will be used in the service authorization process
9. the network will expire after a predefined ID lifetime interval and at that time all sales linked to this ID become closed and bill is created then the vehicle ID is deleted from any storage on the network 0086 Here is another likely operational scenario for an unattended parking facility 0087 On entrance to the unattended parking facility a client or a vehicle operator receives a ticket with a unique bar coded number A vehicle operator finds the available recharging station and connects the vehicle to it by the cable The sensor in the station s cable connector generates a Recharging Cable Connected event and the station displays a request to scan the ticket if a ticket has not already been scanned If the operator first scans the ticket the Ticket Num ber Obtained event is generated and the station displays a request to connect recharging cable After both these opera tions are completed by the vehicle s operator the station dis plays a request to select payment method and or payment amount as it is common now in gasoline stations 0088 Ifa client selects a prepayment amount and makes a payment then no other authorization is required to start recharging If a client has successfully authorized a credit card charge or a client account charge then further definition of recharging duration is needed and the station displays a request to enter either the amount of recharging energy recharging time or battery capacity to fill up
