System for the public use of private wallboxes with integrated payment function for electric vehicles

Abstract

(Main claim - Device / System) Charging device for public use of a private wallbox, comprising: a wallbox (1) for charging electric vehicles, an authentication unit (3) for identifying an external user, Data transfer with a server (6), a settlement unit (4) for initiating and processing a payment, a control logic (2) that only releases the charging process after successful authentication and payment. Subclaims

Description

1. Technical field:

[0001] The invention relates to the field of electromobility, in particular charging equipment for electric vehicles, and relates to a device with which private wallboxes can be made accessible to the public by means of an authentication and billing unit. 2. State of the art:

[0002] Charging stations for electric vehicles are already available that are accessible via public networks and billed through corresponding payment systems. Private wallboxes, on the other hand, are generally intended solely for personal use and have never been equipped with suitable authorization technology or a payment function. This results in a small number of publicly available charging points, even though a technically usable charging infrastructure in the form of private wallboxes exists in large numbers. 3. Object of the invention:

[0003] The invention is based on the objective of improving the availability of public charging infrastructure by making private wallboxes accessible to the general public through suitable measures and at the same time ensuring secure, user-friendly billing of the charging processes. 4. Solution to the task: Device

[0004] The invention transforms a private charging facility for electric vehicles into a charging facility that can be used publicly by third parties: 1. a private wallbox with control and billing unit 2. an authentication unit for identifying a user (e.g., via app, RFID card, QR code or other digital identification means), 3. a billing unit that enables payment initiation (e.g. via credit card, digital wallets, online payment services or roaming platforms for electric mobility), 4. A control logic that only releases the charging process after successful authentication and payment. 5. Advantages of the invention:

[0005] Increasing the number of available public charging points without expanding additional infrastructure.

[0006] Enabling a flexible business model for private wallbox operators. Improving range planning and the everyday usability of electric vehicles. Easy integration into existing systems through standardized interfaces. 6. Example of implementation:

[0007] A private wallbox operator installs an additional module with internet connectivity.

[0008] A driver who is not familiar with the charging process scans a QR code on the wallbox, is redirected to a mobile payment page, selects the desired charging amount, pays by card, and then receives charging authorization. Once completed, the paid energy amount is recorded in the system and credited to the operator.

Claims

(Main claim - Device / System) Charging device for public use of a private wallbox, comprising: a wallbox (1) for charging electric vehicles, an authentication unit (3) for identifying an external user, data transmission with a server (6), a billing unit (4) for initiating and processing a payment, a control logic (2) that releases the charging process only after successful authentication and payment. Subclaims Charging device according to claim 1, wherein the authentication unit comprises a tamper-proof release logic consisting of, for example, a mobile app, QR code, RFID card, digital ID or combinations thereof. Charging device according to claim 1 or 2, wherein the billing unit is equipped with an online payment system, wherein the communication interface (3) is designed for encrypted data transmission. Charging device according to one of the preceding claims, wherein the control logic comprises an internet connection (6) to transmit real-time data (5) (e.g. kW) to a billing backend. Charging device according to one of the preceding claims, wherein the control unit (2) is designed for power regulation of individual tariffs and access rights depending on external control data. Charging device according to one of the preceding claims, wherein the wallbox in any version is designed as a public charging unit.
