DETAILED DESCRIPTION
[0019] The present invention provides a method and system for a single-action ordering method based on pre-arranged agreements between the electric vehicle owner and service provider (electric power utility and/or third party charging service) to charge the vehicle leveraging integrated client and Internet server environment. The single action is the connection of the electrical vehicle (EV) to a charging station. The single-action ordering system of the present invention reduces the number of purchaser interactions needed to place an order and reduces the amount of sensitive information that is transmitted between a vehicle client system and an Internet server authentication system. In one embodiment, the vehicle client is assigned a unique vehicle client identifier and is unique to each vehicle client system. The server system also stores purchaser-specific and vendor-specific billing information which is used for remote billing for services rendered. The server system maps each client identifier to a purchaser which is mapped to the billing account. Along with the order information, a unique identifier of the vendor is also sent so to the billing server so the client is mapped to the vendor and the vendor's electricity rates and policies in order to process billing.
[0020] The single action ordering method is initially enabled when a consumer purchases an EV vehicle. The EV vehicle, when consumer owned, is referred to as the EV Client in the following figures.
[0021] Referring to FIG. 1 (EV Client Identifier/Cloud Registration), shows the EV Client being assigned a unique identifier. The unique identifier 1 can be assigned to the EV Client 2 prior or post delivery to the consumer. A Public/Private Key pair is also assigned to the EV Client. Upon consumer EV Client ownership, the EV Client unique identification and relevant consumer billing information are registered, 3, with a billing transaction service provider 4.
[0022] Referring to FIG. 2 (EV Charge Station Identifier), shows a relative unique identifier 5 being assigned to an EV Charge Station 6. This unique identifier is utilized when the EV Client is connected to the EV Charge Station and is used during the billing transaction process as shown in FIG. 3 (EV Client/Charge Station Billing). A Public/Private Key pair is also assigned to the EV Charge Station during this step (FIG. 2 (A)).
[0023] Referring to FIG. 3 (Electricity Rates and Policies Update Process), shows the process through which a source of electricity rates and policies 7, such as an electric power utility, an EV Charge Service Provider (EVCSP), or other entities transmit current electricity rates and policies 8 to the Cloud Billing Transaction Service 9. The rates component of the Electricity Rates and Policies 8 can be static price schedules (such as fixed rates or time-of-use schedules) which are transmitted infrequently, i.e. only when these schedules change. Rates might also include dynamic price signals (such as critical peak pricing) which are only transmitted for specific days and timeframes, for example, when the electric utility is experiencing an excessive demand for electricity. Pricing policies might include any number of policies which might be applied according to local government regulations, for example, restricting the amount of charge that might be provided during critical peak periods.
[0024] Referring to FIG. 4 (EV Client/Charge Station Billing), shows the process for authenticating the EV client prior to charging the EV and enabling the charging transaction to occur. The EV Client is connected to the EV Charge Station 10. The EV client checks for the charging station ID to determine if it is compliant with the invention 11. If the charging station is not compliant to the single-action ordering system of the present invention (for example, if charging in the EV owner's home) then the EV billing module is not engaged and the billing process is terminated 12 and charging of the EV client can resume. If the charging station is complaint a connection is achieved and both units exchange public key information 13 and initiate a validation procedure 14. If key validation process fails the EV Client transaction is disconnected from the EV Charge Station, the EV Client account is disabled, and all processing is terminated 15. If the key validation process is successful 14 a connection between the EV Client and the billing transaction service provider is established 16 to update and exchange electricity consumption related information such as charge station ID, kilowatts consumed, current policy and rates, etc.. The EV client in turn updates the stored rates and policy information (previously stored in the Cloud Billing Transaction Service as described above in FIG. 3) in the charging station 17. The EV Client checks to see if it still has a connection to the billing transaction service provider 18. If it does the EV Client battery is charged 19. Upon charge completion the EV Client disconnects from the EV charge station 20 and communicates all data relevant to assessing fees for service rendered to a billing transaction service provider 21. Should the EV client and the billing transaction service provider lose their connection, the EV client continues to reestablish its connection until all billing data is transmitted. Upon services rendered the EV Client is disconnected from the EV Charge Station, 18.
[0025] Instances may arise where a connection to a billing transaction service provider cannot be initiated (referred to as an Occasional connection) or fully maintained through completion during a real time EV Client/EV Charge Station exchange 18. In such cases the EV Client and EV Charge station will authorize charging services up to a predetermined credit limit 22 and the EV Client will be charged 23. All associated data and billing information will be cached within the EV Client and the Charge Station. Upon next connection availability, the EV Client 23 will transmit the cached data to a billing transaction service provider 21 and the process will be terminated 24. Additionally any successful future Charge Station connection with the billing system will cause the cache to be transmitted for transaction billing.
[0026] Referring to FIG. 5 (Cloud Billing Process), outlines the process for billing an EV Client for service rendered and making franchise payments to the EV Charge Station and EV OEMs. The Cloud Billing Transaction service 25 calculates the total bill for all EV Client billing for a given period of time. The bill includes battery charging services and processing fees. (The terms for billing period and processing fees are established with the EV Client upon ownership of the vehicle.) At the pre-arranged billing period the Cloud Billing Transaction service attempts to automatically withdraw the calculate fees from the EV Client bank account 26. Note that this withdrawal can be sourced from any type account, i.e. not limited to a bank account, e.g. an account established with the Billing Transaction Provider or any other mutually agreed to source. The EV Client bank 27 determines if there are sufficient funds to make payment. In the event of insufficient funds to make payment and an alternate payment method is not available (such as a credit card) the Cloud Billing Service revokes the Public Keys and or unique identifier of the EV Client and the EV Client is notified that service is disqualified 28. If there are sufficient funds 29 the Cloud Billing Transaction service withdraws funds from the EV Client Bank account then issues a billing statement 30 to the EV Client, issues payment to the EV Charge Station Service Provider (EV CSP) 31, and issues a payment to the EV OEM (Original Equipment Manufacturer) 32. The payments to the EV CSP and EV OEM include Franchise revenue sharing payments that are calculated as a percentage of the battery charging transaction value or per event transaction fees as defined by pre-arranged agreements between all associated parties.
[0027] FIGS. 1, 2, 3 and 4 show a method of which the customer places an order and receives services rendered; a complete service is transacted by the single action of connecting the charging station to an electrical vehicle. The action of physical connection (single action) starts an end-to-end sequence of events that bills the vehicle owner for the charging event, remits payment for services rendered to the EV CSP as well as franchise payment to the EV OEM and EV CSP. Termination of the event is as simple as fully charging the EV batteries or un-plunging the vehicle. Billing is routed automatically to the owner's account via a pre-arranged agreement with the billing transaction provider.
[0028] Referring to FIG. 6 (EV Charge Station Service Provider Update Billing), illustrates the process of direct billing a EV Charge Station Service Provider for a local EV Charge Station update. The EV Charge Station can be updated for example with information such as refreshed keys or polled for maintenance statistics or any other related information. The EV Client 34 is connected to the EV Charge Station 35. When connection is achieved using public key encryption, 36 a validation procedure is initiated. If validation fails the connection is terminated 40. Upon validation, the EV Client sends notification to the Cloud Billing Transaction Provider 41 which in turn notifies the specific EV Charge Station Service Provider 42 that an update can occur. The EV Charge Station Service Provider can than send update collateral to the EV Client 34 via the Cloud Billing Transaction Provider link and the EV Charge Station is updated 37. Upon EV Charge Station update complete validation 38 Billing Transaction data processing occurs and the EV Client sends billing information 39 to the Cloud Billing Transaction Provider 41 and notification to the EV Charge Station Service Provider 42 via the Cloud Billing Transaction Provider 41 with acknowledgement. Also upon EV Charge Station update complete validation 38 the EV Client to EV Charge Station connection is terminated 40. In the event of failure of the EV Charge Station update complete validation 38 the EV Charge Station Service Provider is notified and Termination 40 occurs. Upon successful update the EV Client 39 notifies the Cloud Billing Transaction Provider 41 that billing the local EV Charge Station Service Provider 42 for the update transaction can occur and the process is terminated 40.
