Description

[0001] The invention relates to methods for using an electric vehicle charging station (meaning any vehicle with a rechargeable traction battery, including hybrids) in the absence of a stable internet connection. More specifically, it relates to methods for starting, terminating, and paying for a charging session in the absence of a stable internet connection due to the location of the charging station outside of cellular coverage, such as in underground parking lots or in areas with restricted internet access.

[0002] In most cases, interaction between electric vehicle users and charging stations (CS) is based on the reception and transmission of charging session and payment data to a remote server using software from the user's mobile device (MD), and the reception and transmission of this data by the CS via a wireless internet connection provided by cellular operators. However, the problem of a stable internet connection is becoming increasingly pressing, due to the need to ensure the security of infrastructure facilities located near CS by forcibly restricting internet access. As a result, EV users are unable to initiate a charging session.

[0003] The prior art provides methods for making payments with an unstable Internet connection. A known method is for automatically crediting deposited funds when failures occur [Patent for Invention No. 2677384, IPC G07F 19 / 00; G06Q 20 / 08; G06Q 40 / 02; priority 12 / 14 / 2017], carried out by a processor, including the following steps: receiving a user request for performing a transaction for accepting a cash register, containing the transaction parameters, in the self-service device (SSD) channel; sending a preliminary transaction request to a remote server to check the transaction parameters, which includes the user account identifier; receiving a response from the server and saving it in the SSD; initiating the acceptance of the cash register by the SSD in accordance with the transaction parameters; recording the data of the received cash register during acceptance; transmit data to a remote server, record the occurrence of a failure to send data for executing a transaction using the control system, and save the transaction parameters in the control system memory;activate an automatic funds crediting scenario that ensures the execution of a transaction request based on the said user account identifier without user intervention; automatically initiate a poll of the remote control server; and upon receiving a response from the remote server, transmit the said saved transaction parameters to the said server for its execution; credit the funds to the specified user account.

[0004] The prototype is a method for using a charging station located, for example, underground (underground parking), where there is no network, and the user's mobile phone and the charging station cannot connect to the network, described in the patent "Charging Station Based on a Reverse Code Scan Payment Mode" [Patent CN 221819898 U, IPC B60L 53 / 31; G06Q 20 / 32; G07F 15 / 00, priority 23.11.2023], in which the user scans a QR code on a mobile device using a charger; the write-off management module (cloud platform) reads the information from the QR code, and if the reading is successful (i.e.(successful debit) sends a command signal to the signal control unit; after the signal receiving module in the signal control unit receives the command signal, the charging power transmission device in the charge sending module is started due to the interaction between the control module and the communication module; the charging data receiving module receives the start signal from the charging data transmission module and charges the target vehicle via the charger connected to the charging power transmission device; the charger communicates with the cloud platform via an antenna located outdoors. A disadvantage of this method is its ineffectiveness in the event of forced internet access restrictions in the area where the charging station is located; in this case, placing the antenna outdoors will not ensure a stable internet connection.

[0005] The technical problem solved by implementing the invention is the need to expand the arsenal of technical means designed to start, complete and pay for a charging session at a charging station for electric vehicles in the absence of a stable Internet connection due to the location of the charging station outside the coverage area of ​​​​a cellular operator network, for example, in underground parking lots, or in areas with forced restrictions on Internet operation.

[0006] The technical result achieved by implementing the invention consists in ensuring the possibility of using charging stations for electric vehicles in conditions of the absence of a stable Internet connection in the area where the charging station is located.

[0007] The essence of the invention is expressed in the following set of essential features, ensuring the achievement of the specified technical result: a method for using a charging station (CS) of electric vehicles in the absence of a stable Internet connection, in which the CS exchanges data directly with the user's mobile device (UMD) by means of wireless communication, wherein the method consists of the following steps:

[0008] - the user connects the electric vehicle to the ZS using a cable with a connector;

[0009] - a wireless connection is established directly between the MUP and the ZS;

[0010] - MUP sends a command to the ZS to start the charging session;

[0011] - the charging session is assigned an identifier;

[0012] - the identifiers of the charging session and the user account, as well as the parameters of the charging session after its completion, are saved in the memory of the charging station and in the memory of the MUP;

[0013] - when an Internet connection is established, the saved data is sent to a remote server from the ZS or MUP;

[0014] - all data is stored in the database linked to the remote server;

[0015] - the remote server verifies the fact of payment for the charging session using its identifier;

[0016] - if there is no information in the database about the fact of payment for the charging session, funds are debited from the user's account;

[0017] - information about the fact of payment for the charging session is saved in the database.

[0018] The invention provides a solution to the problem of using the charging station of electric vehicles in conditions of absence, instability or too low data transfer speed through the Internet connection of a remote server with a municipal unitary enterprise or charging station provided by cellular operators, since it allows starting and ending a charging session without pre-payment, interacting directly with the charging station through the municipal unitary enterprise, and payment is made after the restoration of a stable Internet connection.

[0019] The embodiment of the invention is further presented using one example of the claimed method. The electric vehicle user first installs software (hereinafter referred to as the app) on the MUP, registers their account, and links it to a bank account, from which the payment for charging sessions will be debited. An alternative option is to create a virtual refillable account directly in the app.

[0020] When in a stable internet connection, the user can use the app to select a charging station located at an optimal distance from them, build a route to it, and pre-set charging session parameters, such as duration, the required battery charge level of the electric vehicle, and the cost.

[0021] When near a charging station in an area with no internet connection, the user connects the electric vehicle to the charging station using a power cable with a connector. The user then uses the app to establish a wireless connection between the electric vehicle and the charging station. This connection allows the electric vehicle and the charging station to exchange data. Bluetooth, NFC, or Wi-Fi are preferred.

[0022] The MUP sends a command to the charging station to start a charging session and the selected session parameters. A charging session identifier is assigned to the MUP or FS. The charging session and user account identifiers, as well as the charging session parameters after the session ends, are saved in the FS and MUP memory.

[0023] When an internet connection is established, saved data is sent from the charging station or municipal unit to a remote server. The internet connection can be restored in the charging station's area by lifting the cellular operator's internet restriction, or by moving the user from the municipal unit to an area with a stable internet connection after completing the charging session.

[0024] All data received by the remote server is stored in a linked database. The remote server then verifies payment for the charging session using its ID. If payment for the charging session is not recorded in the database, funds are debited from the user's account (either a bank account or a virtual account linked to the user's account).

[0025] The charging session payment details are saved in the database. Subsequently, when an internet connection is established on another device (the MUP or the AP), it also sends the charging session and user account identifiers, as well as the charging session parameters, to the remote server, which also verifies the payment for the charging session using its identifier. However, in this case, the server software identifies the payment and does not debit the user's account again. Notifications can then be sent to the MUP and AP confirming successful payment and preventing the data packet about the completed charging session from being sent again.

[0026] The application can also be configured to automatically connect the MUP to the charging station, automatically start and end the charging session, as well as automatically pay, which is ensured by storing a specific charging station in the MUP’s memory and detecting it when approaching it.

[0027] Thus, the claimed invention ensures the operability of the charging station and the ability to carry out a charging session of an electric vehicle in the absence of a stable Internet connection.
