Description

Technical Field

[0001] The present invention relates to the automotive field, specifically, to the field of automotive battery replacement management, and more specifically, to a battery replacement method and an automotive battery replacement management system based thereon. Background Art

[0002] With the development of battery technology, electric vehicles are becoming more and more popular. Among them, electric vehicles in battery swap mode occupy a large proportion in the market due to their advantage in energy replenishment time. The so-called electric vehicles in battery swap mode refer to electric vehicles that achieve energy replenishment by replacing batteries. When the battery of an electric vehicle is insufficient, it can be replenished immediately by directly replacing the battery at a battery swap station without waiting for charging time. It is simple and efficient, especially for operating vehicles. The time saved can greatly increase production capacity. In the battery swap mode, we have to mention the vehicle battery swap management system, which is a system used to manage battery swap operations. Figure 1 As shown, the automobile battery swap management system generally includes three parts: a cloud management terminal, a battery swap station, and a client. Among them, the cloud management terminal is used to maintain the information of all users, all battery swap station information, and each battery swap information of the user in the cloud. The battery swap station (equipped with a station control system for management) is used to store the replaced batteries and charge these batteries for subsequent battery swaps by users. The client is the operation port for users to apply for battery swaps. After arriving at the battery swap station, the user applies for battery swaps to the battery swap station through the client. Based on the user's application, the battery swap station requests the user's information from the cloud management terminal to perform online authentication of the user, that is, to determine whether the user is eligible for battery swaps (whether he is a legal user, not a blacklisted user). Only users who pass the authentication can obtain the battery swap service of the battery swap station.

[0003] As can be seen from the previous description, the entire battery swapping process nowadays cannot be separated from the support of a good network. If the network is not good, the battery swapping station cannot authenticate the user online. If authentication cannot be performed, legitimate users cannot obtain battery swapping services in a timely manner. However, under the existing technology, it is impossible to guarantee that every battery swapping station and every client area has a good network at all times, which makes it difficult for users to swap batteries. Summary of the Invention

[0004] Therefore, the purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a battery replacement method that can realize battery replacement without a network and an automobile battery replacement management system based on the battery replacement method.

[0005] According to a first aspect of the present invention, a battery replacement method is provided, which is applied to a car battery replacement management system, wherein the car battery replacement management system includes a cloud management terminal, a battery replacement station, and a client, wherein a user uses the client to apply for battery replacement at a battery replacement station through the network, and the battery replacement station requests the cloud management terminal to obtain user information through the network and performs online authentication on the user based on the obtained user information, and performs battery replacement for the authenticated user. The method includes: the client automatically and continuously responds to the user's battery replacement demand to apply to the cloud management terminal for an appointment for battery replacement, and when the network is available, the cloud management terminal generates and sends an offline identifiable battery replacement authentication code to the client and the battery replacement station matched with the user based on the client application. The picture contains the client user information, the battery swap station information matched for the user, the user's vehicle information, the vehicle battery information and the appointment time information; the client user saves the received picture for battery swap authentication; the user applies for battery swap at the battery swap station through the client. When the network is available, the battery swap station directly performs online authentication through the network and swaps the battery for the user who passes the authentication. When the network is unavailable, the battery swap station performs offline authentication on the user based on the picture saved by the user client to authenticate the user for battery swap based on the user information in the picture, the battery swap station information matched for the user, the user's vehicle information, the vehicle battery information and the appointment time information.

[0006] Preferably, the offline identifiable image used for battery swap authentication is a QR code. In some embodiments of the present invention, the QR code is an encrypted QR code, wherein the cloud management terminal generates the encrypted QR code and simultaneously generates a corresponding key for decrypting the information in the QR code, and sends the key to the battery swap station matched to the user, so that the battery swap station decrypts the QR code when performing offline authentication on the user based on the QR code to accurately identify the information therein.

[0007] Preferably, the image that can be identified offline for battery swap authentication is a barcode. In some embodiments of the present invention, the barcode is an encrypted barcode, wherein the cloud management terminal generates the encrypted barcode and generates a corresponding key for decrypting the information in the barcode at the same time, and sends the key to the battery swap station matched to the user, so that the battery swap station can decrypt the barcode to accurately identify the information when performing offline authentication on the user based on the barcode.

[0008] Preferably, an offline identifiable image for battery swap authentication is generated on the cloud management side in the following manner: S1. Obtain user information, battery remaining information, user location information, and information about battery swap stations around the user's location; S2. Calculate all accessible battery swap stations around the user based on the user's battery remaining information, and match the nearest battery swap station, available battery information at the battery swap station, and vehicle queues at the battery swap station, and reservation status of the battery swap station for the user, and match the user with the battery swap station where the battery swap service can be obtained the fastest and the reservation time; S3. Generate and encrypt an offline identifiable image for battery swap authentication that contains user information, matching battery swap station information, and reservation time information.

[0009] According to a second aspect of the present invention, there is provided a vehicle battery swap management system that adopts the battery swap method as described in the first aspect of the present invention, wherein the system includes a client, a battery swap station, and a cloud management terminal, wherein: the client is used to apply to the battery swap station for battery swap when the user's battery needs to be replaced, and to apply to the cloud management terminal for battery swap reservation to obtain an offline identifiable picture for battery swap authentication; the cloud management terminal is used to generate and send an offline identifiable picture for battery swap authentication to the client and the battery swap station matched for the user based on the client application; the battery swap station is used to directly perform online authentication based on the user's battery swap application and perform battery swap for the user who passes the authentication when the network is available, and to perform offline authentication on the user based on the picture saved by the user client when the network is unavailable, so as to authenticate the user for battery swap based on the user information in the picture, the battery swap station information matched for the user, the user's vehicle information, the vehicle-mounted battery information, and the reservation time information.

[0010] Preferably, the offline identifiable image used for battery replacement authentication is an encrypted QR code or an encrypted barcode.

[0011] Compared with the existing technology, the advantages of the present invention are: the battery replacement method of the present invention generates an offline identifiable picture for battery replacement authentication in advance when there is a network and saves it on the client and the battery replacement station. If there is no network after the user arrives at the battery replacement station, the picture can be directly used for offline authentication, preventing the situation where online authentication cannot be performed due to no network and the battery cannot be replaced, thereby greatly improving the battery replacement operation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The embodiments of the present invention are further described below with reference to the accompanying drawings, in which:

[0013] Figure 1 A simplified schematic diagram of the vehicle battery swap management system. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] As described in the background technology, the existing technology for battery swap management of automobiles is highly dependent on the network. If the network is unavailable, battery swapping will be unfeasible, which will greatly affect the user's battery swap efficiency and the operational efficiency of the battery swap management system. In order to solve the limitations brought by the network, the inventors proposed an offline authentication solution. When there is a network, an image (including but not limited to a QR code, barcode, etc.) that can be used for offline authentication is generated in advance. When the network of the battery swap station is unavailable, the image is directly used for offline authentication. When the network is available, the battery swap information is updated to the cloud.

[0016] In order to better understand the present invention, the present invention is described in detail below with reference to the embodiments.

[0017] In the embodiment, an electric heavy truck, a battery replacement mini program as the client (battery replacement mini program), and a picture as a QR code are used as an example to explain in detail the battery replacement process using the present invention.

[0018] Step 1: When the driver of an electric heavy truck finds that the battery is low, he or she can make an appointment to swap batteries through the battery swap app on the mobile phone when the network is available.

[0019] Step 2. Based on the user's application, the cloud management end obtains user information, battery remaining information, user location information, and information about battery swap stations around the user's location. Based on the user's battery remaining information, it calculates all accessible battery swap stations around the user, information about available batteries at the battery swap stations, as well as the vehicle queues at the battery swap stations and the number of battery swap station reservations. It matches the user with the battery swap station where the fastest battery swap service can be obtained, as well as the reservation time. It then generates and encrypts a QR code for battery swap authentication that can be identified offline and contains the user information, the matching battery swap station information, and the reservation time information. The encrypted QR code is sent to the user and the matching battery swap station, and a decryption key is generated and sent to the matching battery swap station for the user.

[0020] Step 3: The driver saves the QR code on his mobile phone, and the battery swap station saves the QR code and key;

[0021] Step 4. The driver arrives at the battery swap station and checks whether the network is available. If the network is available, the driver can apply for battery swap directly through the battery swap applet, or use an encrypted QR code to apply for battery swap. When using an encrypted QR code to apply for battery swap, the user provides the encrypted QR code stored on the mobile phone to the QR code recognition device of the battery swap station. The battery swap station decrypts the information in the QR code (user and vehicle information, battery information, battery swap station information) based on the key. The station control system on the battery swap station authenticates the user based on this information, that is, verifies the authenticity of this information to confirm whether the heavy truck and battery driven by the driver can be swapped at this battery swap station;

[0022] Step 5: If the authentication fails, the battery swap station will not provide the driver with the battery swap service. After the authentication passes, the battery swap station will start the battery swap service to swap the battery for the heavy truck driven by the driver and save the battery swap record. If the network is unavailable, the battery swap record will be saved locally first and uploaded to the cloud management end after the network is available.

[0023] Step 6. After the battery swap is completed, a payment QR code is generated to prompt the driver to make payment. If the network is unavailable, the driver will take a photo of the payment QR code and save it on his mobile phone, and make payment after the network is available.

[0024] Compared with the existing technology, the advantages of the present invention are: the battery replacement method of the present invention generates an offline identifiable picture for battery replacement authentication in advance when there is a network and saves it on the client and the battery replacement station. If there is no network after the user arrives at the battery replacement station, the picture can be directly used for offline authentication, preventing the situation where online authentication cannot be performed due to no network and the battery cannot be replaced, thereby greatly improving the battery replacement operation efficiency.

[0025] It should be noted that although the above describes the various steps in a specific order, it does not mean that the steps must be performed in the above specific order. In fact, some of these steps can be executed concurrently or even in a different order as long as the required functions can be achieved.

[0026] The present invention may be a system, a method and / or a computer program product. The computer program product may include a computer-readable storage medium carrying computer-readable program instructions for causing a processor to implement various aspects of the present invention.

[0027] Computer-readable storage media can be a tangible device that holds and stores the instructions used by an instruction execution device. Computer-readable storage media can, for example, include, but are not limited to, an electrical storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination thereof. More specific examples (non-exhaustive list) of computer-readable storage media include: a portable computer disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanical encoding device, a punch card or a raised structure in a groove on which instructions are stored, for example, and any suitable combination thereof.

[0028] While various embodiments of the present invention have been described above, the above descriptions are intended to be illustrative, non-exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
