Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging pile management, and specifically to a new energy vehicle shared charging management system and method. Background Art

[0002] With the advancement and implementation of the national new energy vehicle industry strategic plan, electrification, intelligence, networking and sharing will be the main development directions of the automotive industry in the future.

[0003] However, throughout the development of new energy vehicles, charging has always been a major concern for consumers. While electric vehicle ownership is rapidly increasing, a severe shortage of charging equipment has led to increasingly difficult and slow charging times, resulting in a poor user experience. Current charging management for new energy vehicles still relies on drivers navigating maps to find charging spots, making it inefficient. Therefore, intelligent and shared charging equipment is crucial. Summary of the Invention

[0004] The purpose of the present invention is to provide a new energy vehicle shared charging management system and method, which can fully utilize existing charging pile equipment, promote the construction and popularization of charging piles, and solve the problem of difficulty in charging electric vehicles.

[0005] To achieve this purpose, the present invention designs a new energy vehicle shared charging management system, which is characterized by: it includes a charging pile controller, a charging management application module, a shared charging management server and a shared charging management client;

[0006] The charging pile controller is installed on the corresponding shared charging pile and can control the charging operation of the shared charging pile. The charging pile controller is used to download the charging management application module and set the charging idle time period and location coordinates of the shared charging pile in the charging management application module;

[0007] The charging management application module is used to upload the charging idle time period and location coordinates of the corresponding shared charging pile to the shared charging management server;

[0008] The shared charging management client is used to query available shared charging piles through the shared charging management server based on the location coordinates of the shared charging piles and the idle charging time period. The available shared charging piles are shared charging piles that are within a preset distance range from the shared charging management client, have the charging management application module installed, and are in the idle charging time period.

[0009] The shared charging management client is used to select a shared charging pile from the available shared charging piles and determine the charging mode after the shared charging pile is selected. When the charging mode is selected as scheduled charging, the shared charging management client sends a scheduled charging instruction to the charging management application module corresponding to the selected shared charging pile through the shared charging management server. The charging management application module controls the working state of the selected shared charging pile to change to a waiting state for charging. When the vehicle equipped with the shared charging management client (the vehicles in this article refer to new energy electric vehicles) arrives at the selected shared charging pile, the charging management application module performs vehicle identity authentication. After the vehicle identity authentication is passed, the shared charging management client sends a charging instruction to the charging management application module corresponding to the selected shared charging pile through the shared charging management server. The charging management application module controls the charging pile controller to charge the vehicle.

[0010] When direct charging is selected as the charging mode, the charging management application module performs vehicle identity authentication. After the vehicle identity authentication is passed, the shared charging management client sends a charging instruction to the charging management application module corresponding to the selected shared charging pile through the shared charging management server. The charging management application module controls the working state of the selected shared charging pile to change to the charging state, and the charging management application module controls the charging pile controller to charge the vehicle.

[0011] Beneficial effects of the present invention:

[0012] The present invention makes private charging piles shared and can be quickly put into the electric vehicle market, thereby achieving full utilization of charging pile equipment, promoting the construction and popularization of charging piles, and solving the problem of difficulty in charging electric vehicles; at the same time, it provides additional income for charging pile owners, which will be welcomed by the majority of electric vehicle users, and can also save charging resources for the country and achieve effective resource utilization. At the same time, it can help car companies achieve innovation, transformation and upgrading, improve the competitiveness of core products, and contribute personal strength to the development of new energy vehicle industry.

[0014] Among them, 1—charging pile controller, 2—charging management application module, 3—shared charging management server, 4—shared charging management client. DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1 The new energy vehicle shared charging management system shown includes a charging pile controller 1, a charging management application module 2, a shared charging management server 3 and a shared charging management client 4;

[0017] The charging pile controller 1 is installed on the corresponding shared charging pile and can control the charging operation of the shared charging pile. The charging pile controller 1 is used to download the charging management application module 2 from the Internet and set the charging idle time period, location coordinates and charging standards of the shared charging pile in the charging management application module 2;

[0018] The charging management application module 2 is used to upload the charging idle time period, location coordinates and charging standards of the corresponding shared charging pile to the shared charging management server 3;

[0019] The shared charging management client 4 is used to query the available shared charging piles through the shared charging management server 3 according to the location coordinates of the shared charging piles and the idle charging time period. The available shared charging piles are shared charging piles that are within a preset distance range (e.g., 5 km) from the shared charging management client 4, have the charging management application module 2 installed, and are in the idle charging time period;

[0020] The shared charging management client 4 is used to select a shared charging pile from the available shared charging piles and determine the charging mode after the shared charging pile is selected. When the charging mode is selected as scheduled charging, the shared charging management client 4 sends a scheduled charging instruction to the charging management application module 2 corresponding to the selected shared charging pile through the shared charging management server 3. The charging management application module 2 controls the working state of the selected shared charging pile to change to a waiting state for charging. When the vehicle equipped with the shared charging management client 4 arrives at the selected shared charging pile, the charging management application module 2 performs vehicle identity authentication. After the vehicle identity authentication is passed, the shared charging management client 4 sends a charging instruction to the charging management application module 2 corresponding to the selected shared charging pile through the shared charging management server 3. The charging management application module 2 controls the charging pile controller 1 to charge the vehicle.

[0021] When direct charging is selected as the charging method, the charging management application module 2 performs vehicle identity verification. After the vehicle identity verification is passed, the shared charging management client 4 issues a charging instruction to the charging management application module 2 corresponding to the selected shared charging pile through the shared charging management server 3. The charging management application module 2 controls the operating state of the selected shared charging pile to change to the charging state, and the charging management application module 2 controls the charging pile controller 1 to charge the vehicle. During charging, the charging pile controller 1 exchanges information with the vehicle's battery controller to obtain real-time charging power data, charging status data, vehicle battery status data, charging cost data, and remaining charging time data. The real-time charging power data, charging status data, vehicle battery status data, charging cost data, and remaining charging time data are then transmitted to the shared charging management client 4 via the charging management application module 2 and the shared charging management server 3. The present invention designs both scheduled charging and direct charging methods upon arrival at the charging location, allowing users to select according to their personal needs.

[0022] In the above technical solution, the process of the charging management application module 2 performing vehicle identity authentication is as follows: when the charging gun of the selected shared charging pile is connected to the vehicle charging seat, the shared charging management client 4 sends the user account ID and the VIN information of the vehicle bound to the shared charging management client 4 to the charging management application module 2 through the shared charging management server 3;

[0023] After receiving the user account ID and vehicle VIN information, the charging pile controller 1 obtains the VIN information broadcast on the vehicle CANBUS through the data communication interface (NC1 on the national standard charging gun and the vehicle charging dock is used as CANH, and NC2 is used as CANL). Based on the received user account ID, the charging management application module 2 downloads the corresponding user account ID and the bound vehicle VIN information uploaded by the user from the shared charging management server 3. The charging management application module 2 verifies the received user account ID with the corresponding user account ID uploaded by the user (i.e., compares whether the IDs are consistent). The received vehicle VIN information is also verified with the bound vehicle VIN information and the VIN information broadcast on the vehicle CANBUS obtained by the charging pile controller 1 (i.e., compares whether the VIN information of the above three is consistent). If both the user account ID verification (i.e., the two IDs are consistent) and the vehicle VIN verification pass (the VIN information of the above three is consistent), the vehicle identity verification is considered to have passed. The user account ID and the bound vehicle VIN information are related to the security of shared charging and the accuracy of charging fee calculation, so the above strict verification is necessary. The VIN information uses the vehicle's real-time VIN information, historical uploaded VIN information and the vehicle VIN information transmitted by the shared charging management client 4 to achieve consistency recognition, ensuring the accuracy of the vehicle information.

[0024] In the above technical solution, the shared charging management server 3 stores the corresponding user account ID and bound vehicle VIN information uploaded by the user. The user needs to register with the shared charging management server 3 through the shared charging management client 4 before use.

[0025] In the above technical solution, when the charging management application module 2 downloads the corresponding user account ID and bound vehicle VIN information uploaded by the user from the shared charging management server 3, in order to prevent user information leakage and malicious tampering, symmetric encryption is used to encrypt data transmission.

[0026] In the above technical solution, during the process from vehicle identity verification to full charge of the vehicle, if the connection between the charging gun of the selected shared charging pile and the vehicle charging seat is interrupted (the charging gun CC connection signal (vehicle control device connection confirmation signal) is disconnected), and the interruption time is greater than the preset time, the vehicle identity verification needs to be repeated before charging can continue. If the connection between the charging gun of the selected shared charging pile and the vehicle charging seat is interrupted, and the interruption time is less than or equal to the preset time, charging will be resumed directly without the need for re-authentication of the vehicle. This prevents theft charging, improves charging efficiency, and prevents useless repeated verification.

[0027] In the above technical solution, the shared charging management client 4 is used to select the actual shared charging pile for use from among the available shared charging piles based on the coordinate locations of the available shared charging piles and the real-time positioning signal of the shared charging management client 4, using the principle of closest navigation distance, fastest navigation time, least number of navigation traffic lights, or a driver-selected method. The present invention exchanges data with the vehicle's navigation software, marking the coordinate locations of the available shared charging piles in the navigation software. The navigation software then provides accurate navigation information, making it easier for users to find the location of the selected shared charging pile for use.

[0028] In the above technical solution, when the charging mode is selected as scheduled charging, when the vehicle equipped with the shared charging management client 4 does not arrive at the selected shared charging pile for charging within the preset time, the charging management application module 2 controls the working state of the selected shared charging pile to be restored to the charging idle state.

[0029] In the above technical solution, if, at the end of the idle time period of charging work, the charging of the current vehicle is not completed, the charging management application module 2 is used to send a notification to the mobile phone of the charging pile owner whether to extend the idle time period of charging work. If the mobile phone of the charging pile owner replies to the charging management application module 2 to agree to extend the time and sets a new idle time period of charging work, the current vehicle continues to charge. If the mobile phone of the charging pile owner replies to the charging management application module 2 to disagree to extend the time, the charging management application module 2 terminates the charging process of the current vehicle and sends a notification that the idle time of charging work has passed to the shared charging management client 4 through the shared charging management server 3. At the same time, according to the deduction agreement formulated when the user account ID is registered, the relevant fees are deducted. The present invention takes into account the problem that the overall charging time exceeds the idle time period of charging work, and designs a method of giving priority to the charging pile owner to ensure the rights and interests of the charging pile owner.

[0030] A new energy vehicle shared charging management method comprises the following steps:

[0031] Step 1: Install the charging pile controller 1 on the corresponding shared charging pile and control the charging operation of the shared charging pile. Control the charging pile controller 1 to download the charging management application module 2 and set the charging idle time period and location coordinates of the shared charging pile in the charging management application module 2;

[0032] Step 2: The charging management application module 2 uploads the charging idle time period, location coordinates and charging standards of the corresponding shared charging pile to the shared charging management server 3;

[0033] Step 3: The shared charging management client 4 queries the available shared charging piles through the shared charging management server 3 based on the location coordinates of the shared charging piles and the idle charging time period. The available shared charging piles are shared charging piles that are within a preset distance range from the shared charging management client 4, have the charging management application module 2 installed, and are in the idle charging time period.

[0034] Step 4: The shared charging management client 4 selects a shared charging pile from the available shared charging piles, and determines the charging mode after selecting the shared charging pile. When the charging mode is selected as scheduled charging (the reservation time is set to 0-10 minutes, the reservation is automatically canceled after 10 minutes, and the charging pile returns to an idle state), the shared charging management client 4 sends a scheduled charging instruction to the charging management application module 2 corresponding to the selected shared charging pile through the shared charging management server 3. The charging management application module 2 controls the working state of the selected shared charging pile to change to a waiting state for charging. When the vehicle equipped with the shared charging management client 4 arrives at the selected shared charging pile, the charging management application module 2 performs vehicle identity authentication. After the vehicle identity authentication is passed, the shared charging management client 4 sends a charging instruction to the charging management application module 2 corresponding to the selected shared charging pile through the shared charging management server 3. The charging management application module 2 controls the charging pile controller 1 to charge the vehicle.

[0035] When direct charging is selected as the charging mode, the vehicle first drives to the selected shared charging pile. Then, the charging management application module 2 performs vehicle identity authentication. After the vehicle identity authentication is passed, the shared charging management client 4 sends a charging instruction to the charging management application module 2 corresponding to the selected shared charging pile through the shared charging management server 3. The charging management application module 2 controls the working state of the selected shared charging pile to change to the charging state through the charging pile controller 1. The charging management application module 2 controls the charging pile controller 1 to charge the vehicle.

[0036] Step 5: During the process from vehicle identity verification to full charge, if the connection between the charging gun of the selected shared charging pile and the vehicle charging base is disconnected, and the interruption time is greater than the preset time (e.g., 20 seconds), re-vehicle identity verification is required to continue charging. If the connection between the charging gun of the selected shared charging pile and the vehicle charging base is disconnected, and the interruption time is less than or equal to the preset time, charging is directly resumed without re-vehicle identity verification.

[0037] Step 6: If, at the end of the charging idle time period, the current vehicle is not fully charged, the charging management application module 2 is used to send a notification to the mobile phone of the charging pile owner asking whether to extend the charging idle time period. If the mobile phone of the charging pile owner replies to the charging management application module 2 that it agrees to extend the time and sets a new charging idle time period, the current vehicle continues to charge. If the mobile phone of the charging pile owner replies to the charging management application module 2 that it disagrees to extend the time, the charging management application module 2 terminates the charging process of the current vehicle and sends a notification that the charging idle time has expired to the shared charging management client 4 through the shared charging management server 3. At the same time, according to the deduction agreement formulated when the user account ID is registered, the relevant fees are deducted;

[0038] If the current vehicle is fully charged before the end of the idle charging period, the shared charging service will be terminated, and the relevant fees will be deducted according to the deduction agreement formulated when the user account ID was registered.

[0039] In the present invention, private charging piles are shared, achieving efficient resource utilization, solving the problem of difficulty and slow charging of electric vehicles, and providing convenience for new energy vehicle users. It also increases additional income for charging pile owners and promotes the popularization of charging equipment. In addition, the charging piles are installed with a charging management application module 2, which can monitor and manage the charging pile status online and provide feedback to the shared charging management server 3.
