By implementing the optional implementation mode, the Bluetooth link address information of the Bluetooth hardware wallet at the end of the pile can be read by the Bluetooth hardware wallet at the end of the pile and the NFC tag at the end of the vehicle, so that the Bluetooth link between the Bluetooth hardware wallet at the end of the pile and the Bluetooth hardware wallet at the end of the vehicle is established for data communication between the two parties. Specifically, the NFC tag at the position, close to the vehicle end charging port, of the NFC card reader module at the position of the charging gun interface is bound with the vehicle end Bluetooth hardware wallet in a one-to-one mode, Bluetooth link address information of the vehicle end Bluetooth hardware wallet is stored in the NFC tag, therefore, the NFC card reader module can read Bluetooth link address information in the NFC tag through near field communication, the read Bluetooth link address information is transmitted to the stub end Bluetooth hardware wallet through a wired mode or other data transmission modes, and the stub end Bluetooth hardware wallet receives Bluetooth link address information of the vehicle end Bluetooth hardware wallet transmitted by the NFC card reader module.
Step 102: based on the Bluetooth link address information, a first Bluetooth link is established between the pile end Bluetooth hardware wallet and the vehicle end Bluetooth hardware wallet.
In the embodiment of the invention, after the pile end Bluetooth hardware wallet acquires the Bluetooth link address information of the vehicle end Bluetooth hardware wallet, the pile end Bluetooth hardware wallet identifies the link vehicle end Bluetooth hardware wallet through the Bluetooth link address information, establishes a Bluetooth communication channel with the vehicle end Bluetooth hardware wallet, and starts a subsequent transaction flow.
Step 103: based on the first Bluetooth link, the stub end Bluetooth hardware wallet actively initiates a quota collection request or receives a quota payment request initiated by the vehicle end Bluetooth hardware wallet.
In the embodiment of the present invention, after the first bluetooth link is established between the stub bluetooth hardware wallet and the car bluetooth hardware wallet, data communication can be performed between the stub bluetooth hardware wallet and the car bluetooth hardware wallet, including: the pile end Bluetooth hardware wallet initiatively initiates a quota collection request to the car end Bluetooth hardware wallet, or the car end Bluetooth hardware wallet initiatively initiates a quota payment request to the pile end Bluetooth hardware wallet, and the two modes are that the car end Bluetooth hardware wallet performs payment operation and the pile end Bluetooth hardware wallet performs collection operation.

The process of data communication between the pile end Bluetooth hardware wallet and the vehicle end Bluetooth hardware wallet can be realized in the following modes: the Bluetooth chip provides a Bluetooth communication channel between the target hardware wallet and the SE in the current hardware wallet, and transmits the transaction information between the target hardware wallet and the SE in the current hardware wallet. After the target hardware wallet and the current hardware wallet are paired, the target hardware wallet sends a command to a bluetooth chip of the current hardware wallet in a bluetooth wireless transmission mode, the bluetooth chip forwards the command to the SE, and sends response data of the SE to the target hardware wallet in a bluetooth wireless transmission mode through the bluetooth chip, as shown in fig. 3.
By implementing the optional implementation manner, in the communication process, if the target hardware wallet is the stub-end bluetooth hardware wallet and the current hardware wallet is the car-end bluetooth hardware wallet, the stub-end bluetooth hardware wallet sends the quota collection request to the second bluetooth chip of the car-end bluetooth hardware wallet through the first bluetooth chip, and the second bluetooth chip forwards the quota collection request to the second SE chip and returns the response data of the second SE chip to the first bluetooth chip. If the target hardware wallet is the vehicle-end Bluetooth hardware wallet and the current hardware wallet is the pile-end Bluetooth hardware wallet, the vehicle-end Bluetooth hardware wallet sends the quota payment request to a first Bluetooth chip of the pile-end Bluetooth hardware wallet through a second Bluetooth chip, the first Bluetooth chip forwards the quota payment request to the first SE chip, and response data of the first SE chip is returned to the second Bluetooth chip.
Step 104: based on the quota collection request or the quota payment request, the pile end Bluetooth hardware wallet reads the balance in the vehicle end Bluetooth hardware wallet, if the balance is sufficient, the first digital currency transaction is executed between the pile end Bluetooth hardware wallet and the vehicle end Bluetooth hardware wallet, and charging can be performed after the transaction is completed.
In the embodiment of the invention, after the pile-end Bluetooth hardware wallet initiates a quota collection request or receives a quota payment request, the balance in the vehicle-end Bluetooth hardware wallet needs to be read, whether the balance is sufficient or not is determined, if the balance is sufficient, the first digital money transaction can be executed between the pile-end Bluetooth hardware wallet and the vehicle-end Bluetooth hardware wallet, namely the vehicle-end Bluetooth hardware wallet pays for the digital money transaction of the pile-end Bluetooth hardware wallet, and charging can be carried out after the transaction is completed.
As an optional implementation manner, after the pile-end bluetooth hardware wallet reads the balance in the car-end bluetooth hardware wallet, if the balance is not enough, the user needs to be prompted to "wallet balance is not enough", and the user is prompted to recharge, after the user completes recharging, the pile-end bluetooth hardware wallet needs to execute step 103 again, that is, the pile-end bluetooth hardware wallet initiatively initiates a quota collection request or passively receives a quota payment request, and then reads the balance in the car-end bluetooth hardware wallet again, so that the first digital money transaction can be executed after the wallet balance is enough.
In the implementation mode, a display or a loudspeaker can be arranged at the pile end or the vehicle end, and various information of a user is prompted through a screen or sound, wherein the various information includes information of success or failure of Bluetooth link, information of insufficient balance and the like.
By implementing the optional implementation mode, whether the digital currency transaction can be realized or not can be confirmed by judging the balance information of the vehicle-end Bluetooth hardware wallet before the transaction, the redundancy of a data transmission process and a transaction process caused by insufficient balance is avoided, the transaction efficiency is improved, and the transaction accuracy is ensured.
As another alternative, the car-end bluetooth hardware wallet may be connected with the client application of the user to implement the digital currency charging and synchronization functions.
In the implementation mode, the vehicle-end Bluetooth hardware wallet can be connected with the client application of a user through Bluetooth communication, and the user operates on the client application, namely the wallet APP, so that the functions of digital currency recharging and synchronization are realized.
By implementing the optional implementation mode, the functions of charging and synchronizing can be provided for the user under the condition of confirming that the balance in the wallet is insufficient, the usability of the wallet is improved, and better use experience is provided for the user.
Step 105: based on the actual charging amount and the amount of the first digital currency transaction, the stub bluetooth hardware wallet determines whether change is required, if so, step 106 is executed.
In the embodiment of the invention, after the first digital currency transaction is executed between the stub end Bluetooth hardware wallet and the vehicle end Bluetooth hardware wallet, namely the vehicle end Bluetooth hardware wallet pays a certain amount to the stub end Bluetooth hardware wallet, the charging gun is inserted into the vehicle end charging port for charging, the charging can be finished by a user or a charging pile, and specifically, whether the charging is finished or not can be controlled by presetting time, electric quantity or other conditions. After charging is finished, the pile end Bluetooth hardware wallet records an actual charging amount, calculates an actual charging amount according to the actual charging amount, compares the actual charging amount with the amount of the first digital currency transaction, if the actual charging amount is less than the amount of the first digital currency transaction, indicates that change is needed, returns the remaining amount to the car end Bluetooth hardware wallet, and at the moment, the pile end Bluetooth hardware wallet serves as a payer and the car end Bluetooth hardware wallet serves as a payee.
Step 106: and the pile end Bluetooth hardware wallet judges whether the first Bluetooth link is normal or not, and if not, a second Bluetooth link is established between the pile end Bluetooth hardware wallet and the car end Bluetooth hardware wallet based on the Bluetooth link address information.
In the embodiment of the invention, before the gun is pulled out for change making, whether the Bluetooth communication between the stub end Bluetooth hardware wallet and the vehicle end Bluetooth hardware wallet is normally linked or not needs to be confirmed, if the connection is abnormal, the stub end Bluetooth hardware wallet needs to re-identify the vehicle end Bluetooth hardware wallet to be linked based on the Bluetooth link address information in the step 101, a second Bluetooth link is established with the vehicle end Bluetooth hardware wallet, and if the second Bluetooth link is established successfully, the second digital currency transaction, namely change making, can be realized based on the second Bluetooth link.
As an optional implementation manner, after the stub bluetooth hardware wallet attempts to establish the second bluetooth link with the car-end bluetooth hardware wallet, if the second bluetooth link is failed to be established, the user needs to be prompted to "please re-establish the link, no change is made in the transaction", and meanwhile, the reconnection number may be set, and after the reconnection number is reached, the normal communication between the stub bluetooth hardware wallet and the car-end bluetooth hardware wallet may be implemented in another communication manner supported by the bluetooth hardware wallet. If the link is normal, it indicates that the first bluetooth link established in step 102 is not abnormal, and the second digital money transaction, i.e., change, can be continuously implemented based on the first bluetooth link.
Step 107: based on the first Bluetooth link or the second Bluetooth link, the second digital currency transaction is executed between the pile end Bluetooth hardware wallet and the vehicle end Bluetooth hardware wallet, and the change making and the charging are completed.
In the embodiment of the invention, no matter the Bluetooth connection is carried out for the first time or the second time or the Bluetooth connection is carried out for the first time or the second time, under the condition that the communication between the stub end Bluetooth hardware wallet and the vehicle end Bluetooth hardware wallet is kept smooth, the stub end Bluetooth hardware wallet starts a payment process, the residual amount is paid to the vehicle end Bluetooth hardware wallet through the Bluetooth communication, the second digital currency transaction is executed, the change making is realized, and the charging is completed.
As an optional implementation manner, the post-end bluetooth hardware wallet may be connected to a client application of a user and a synchronization device dedicated to a charging pile operator, so as to implement a digital currency synchronization function.
In this implementation, stake end bluetooth hardware wallet can be connected with user's customer end application, the exclusive synchronous equipment of electric pile operator through bluetooth communication or other communication modes, and the user carries out the synchronization operation on customer end application is wallet APP promptly, and the operator carries out the synchronization operation on the exclusive synchronous equipment of electric pile operator, realizes the synchronization function.
