TECHNICAL FIELD The invention is related to a wireless charging system for electric vehicles.

Known State of the Art

One of the important problems in charging electric vehicles today is the lack of charging points. Electric vehicle charging units charge vehicles in a long time and it is not possible to charge every vehicle, because all types of sockets are not available at the charging stations. Users are required to contact the charger while charging and terminating the charge in difficult outdoor weather conditions and health conditions (such as covid 19). In addition, the touch-sensitive surfaces do not work when the chargers are in contact with liquids and constitute a risk, as there is an electrical connection.

As the vehicles are in a physical connection with the charging units, users are required to wait by the side of the vehicle during charging. Users are also unable to track their vehicle information, payment methods, and received energy information because they are not displayed by the chargers. (Such as Vehicle Battery status, Charging time, Charging cost, Vehicle and user information.)

Also, alternative payment methods are not made available to users at the present. (Usually, energy is purchased in return for numbers with a balance card issued by the Energy Provider organization). For this, it is required to get in contact with the charger again. At the present, no information and data analysis is being made about the Charging Points in the existing systems. (The points which users use the most to get energy, age range, gender, Amount Received, Vehicle models, etc.). Users are not able to find charging points because charging points do not work in integration with users' mobile applications. In addition, the charging status and vehicle information cannot be viewed and tracked instantly over the mobile application.

The summary of the application number 2018/11932, which emerged as a result of technical research is as follows: “This invention relates to a battery wireless charging system for charging vehicles and devices containing batteries (especially electric vehicles, electric ships, computers, etc.) consisting power source, inverter, energy transmitter, energy receiver, battery charger, ground control and communication unit, vehicle control unit, vehicle communication and location positioning device, server, mobile device and web interface parts.”

As can be seen, the system is related to a battery wireless charging system, and it does not mention a structure that can provide a solution to the disadvantages mentioned above.

As a result, due to the drawbacks described above and the inadequacy of the existing solutions on the subject, it was necessary to make an improvement in the relevant technical field.

Objective of the Invention

Unlike the structures used in the current art, the invention aims to provide a structure with different technical features that brings a new perspective in this field.

An objective of the invention is to enable the vehicles to be charged while they are running or in parked position in vehicle fuel stations and in vehicle parking areas, by means of wireless charging surfaces (Wireless Charging Unit).

An objective of the invention is that, when electric vehicles are traveling on the road and they pass to the "charging lanes" located on the roadside, the surface of which is indicated with illuminated and non-illuminated symbols and designated as charging points, to establish connection with the charging point and confirm whether it will receive a charge or not, and when the confirmation is received, to provide partially free or paid electricity charge to the vehicle while it is in motion on the charging lane. Another objective of the invention is to enable users to charge their vehicles without touching the charging units.

The invention is a wireless charging system for electric vehicles to fulfill the objectives described above, wherein it comprises;

• Stationary charging unit, which is fed from the mains power line and enables the vehicle to be charged wirelessly at a stationary point, or a charging lane unit that allows charging along a lane/road while the vehicle is in motion,

Detailed Description of the Invention

In this detailed description, preferred embodiments of the invention are explained only for a better understanding of the subject and without any limiting effect.

In the system according to the invention, the Main Central Server (1) transfers all the data to the Database (2) and manages the system. Brand/Model/License Plate Information of Vehicles, Customer Information (Telephone information (optional), Name Information (user information will be displayed when the user enters the system), charging points information, Energy Price information, and other information are available in the Database (2).

In a configuration of the system according to the invention, when the vehicle (9) approaches the wireless stationary charging station (5.1 ) supplied from the mains power line (8), contact is established with the vehicle (9) for charging, by means of the plates of the stationary charging unit (5.1) rising from the ground, or when it approaches, wireless charging station (5.1) establishes the direct connection with the vehicle (9) for charging. The stationary charging unit (5.1) is marked with illuminated and/or non- illuminated symbols in parking areas.

In an alternative configuration of the system according to the invention, when the electric vehicles (9) pass to the charging strip units (5.2) on the roadside, the surfaces of which are marked with illuminated and/or non-illuminated symbols, while driving, confirmation is made with the charging strip unit (5.2) whether it will receive a charge or not. Once the confirmation is received, the vehicle (9) can receive partially free or paid electricity charge to while it is in motion on the charging lane, and can charge the vehicle (9) while it is on the road in the charging lane.

When the vehicle (9) users want to use the stationary charging unit (5.1) or the charging lane unit (5.2), they log in to a mobile application (6) and press the "Vehicle and Wireless Charger matching" button and perform matching of the vehicle (9) and charging units (5.1, 5.2) over the mobile application (6) by selecting the vehicle (9) and the charging unit (5.1, 5.2) on Bluetooth. If the matching is successful, information is given with the light markers on the stationary charging unit (5.1) or the charging lane unit (5.2) and with the mobile application. If the matching is unsuccessful, the reason for the failure is given as information by the light signs on the stationary charging unit (5.1) or the charging lane unit (5.2) and by the mobile application.

After matching is completed successfully, the user can buy energy by typing the amount he defines in TL on the "Buy Energy" tab on the mobile application (6) (according to TL/kw account from the interface defined in the system before). The user can also buy it by typing the kW energy value defined by himself. After entering the information, the payment method is selected from the "make payment" tab at the bottom. Price information is obtained over the Online Web Server (3) by establishing contact with the EMRA (Energy Market Regulatory Authority) WEB Service and receiving the current Price kW value. For the current price, a query is sent to EMRA at intervals to be determined by the Main Central Server (1) and the price information is updated with the response from EMRA

Once the matching is completed, information registered in the database (2) is received by the mobile application (6). In line with the data received from the database (2), information such as user information, vehicle (9) information (Brand, Model, License Plate...), current charge status, total kilometers that can be traveled with the current charge and charging time are displayed on the screen.

Payment is made from mobile application by virtual payment method, which is known as online method. For the payment result, connection is established with the payment provider registered on the online web server (3) and the confirmation or rejection information is displayed on the mobile application (6) screen. If approval is received, the stationary charging unit (5.1) or the charging lane unit (5.2) starts to charge the vehicle (9) with the energy corresponding to the pre-selected payment amount. In case of a power outage during charging, the uninterruptible power supply (7) located between the mains power line (8) and the stationary charging unit (5.1) takes over and charges the vehicle (9). The capacity of the UPS (uninterruptible power supply) (7) is capable of charging a minimum of 1 vehicle (9).

The vehicle (9), positioned at the fixed charging unit (5.1) and being charged, remains in communication with the wireless charging point that has been previously connected via Bluetooth during the charging transfer. If the vehicle owner wants to move the vehicle (9), an audible and visual alert is given on the vehicle (9) screen and the mobile application (6). The owner of the vehicle (9) is asked whether he desires to move the vehicle (9), and if the owner wants to move the vehicle (9), approval is given. After the approval is given, the vehicle (9) is disconnected from the stationary charging unit (5.1). The vehicle (9) cannot be moved without disconnection. The price amount corresponding to the amount of energy that was not received is credited back to the account to which the payment was made. The payback process is performed by the communication of the stationary charging unit (5.1) with the main central server (1) over the online web server (3).

When the owners of the vehicles (9) using the charging lane unit (5.2), click the “Buy energy” tab on the mobile application (6), pre-authorization is performed on the card information he defined. A number determined through the main central server (1) is pre authorized. As a result of the pre-authorization, the confirmation or rejection information is displayed by contacting the payment provider registered on the online web server (3). After the approval of the pre-authorization process, the vehicle (9) starts to receive energy while traveling on the charging lane.

If the vehicle (9) leaves the charging lane unit (5.2) before the charging is completed, or when there is a power outage, the user is informed by the vehicle (9) and the mobile application. If the vehicle (9) does not return to the charging lane unit (5.2) or electricity is not restored, the connection between the vehicle (9) and the charging lane unit (5.2) is broken. The main center server (1) informs the user about the amount of energy received over the mobile application (6) and the corresponding payment amount. The same information is given on the main central server (1) and the amount corresponding to the received energy is allocated from the amount in the pre-authorization. After the allocation process is completed, the user is informed over the mobile application (6).

The stationary charging unit (5.1) and the charging lane unit (5.2) establish connection with the Database (2) via the Landline and Mobile online line box (4). The landline is the main internet provider. In addition, when charging connections are established between the vehicle (9) and the charging units (5.1, 5.2), mobile internet connection (Wi-Fi - virtual modem) is established between the charging units (5.1, 5.2) and the vehicle (9) over the mobile application (6) of the user. In case of instantaneous landline problems, a connection is established with the main central server (1) over the mobile internet connection. Connection is established over (3G, 4.5G and 5G) operators.

When there is an electricity or data problem, or when the main central server cannot establish communication with the charging units (5.1, 5.2), the charging units (5.1, 5.2) send a signal indicating that there is a problem with the main central server (1) and switch themselves into the warning mode. The charging units (5.1, 5.2) problem warning is shared instantly from the mobile application (6) to the users, together with the warning code.

The Mobile Application (6) establishes connection with the charging units (5.1 , 5.2) via the Web Server (3). The user logs in to the Mobile Application (6) or the application in the vehicle (9) and clicks on the nearest charging points tab that appears in the mobile application menu. The Mobile Application (6) accesses location information and displays the list of the charging units (5.1, 5.2). The following data appears under each list: km distance from the charging units (5.1, 5.2), whether there is fast charging, Kw price information and station status information icons. Selected charging units (5.1 , 5.2) can be added as a road route stop by navigation via Google map and/or Yandex map-like map systems. During the charging process, the user can monitor the charging information of his vehicle from the vehicle information by logging into the mobile application (6).

Mass analyses are performed according to the information received from the Mobile Application (6) and charging units (5.1, 5.2). Information such as the points which users use the most to get energy, age range, gender, Amount of Energy Received, vehicle models, etc. is collected and regional analysis and assessment data are obtained. This way, contribution is made to urbanization, settlement and analyses in mass.
