DETAILED DESCRIPTION
[0027] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
[0028] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the corresponding data protection laws and policies of the country where they are located and with the authorization given by the owner of the corresponding device.
[0029] At present, electric vehicles and charging piles mainly adopt GB / T 18487.1-2015 (Electric Vehicle Conductive Charging System - Part 1: General Requirements) and GB / T 27930-2015 (Communication Protocol between Off-Board Conductive Charger and Battery Management System of Electric Vehicle).
[0030] However, due to restrictions imposed by national standards, the current maximum charging current is only 400 A. Due to the rapid development of charging technology, there is a strong demand for high-current charging, which can be achieved through private protocols for charging piles or by starting to apply local high-current charging protocol standards based on national standards.
[0031] The private protocol for charging piles is based on the national standard CAN (Controller Area Network) communication and GB / T 27930. It customizes exclusive private messages between charging piles and vehicles to achieve the identity of the charging piles, and then realizes high-current charging by modifying the current offset.
[0032] However, the private protocol for charging piles is customized and developed by charging pile companies and car companies. Both charging piles and vehicles need to be developed, which leads to problems of complex compatibility between charging piles and difficult scalability.
[0033] The group standard only includes a high-current charging implementation protocol, but lacks testing standards and certification systems, such as protocol consistency testing and charging performance testing. If there is a design mismatch between the charging pile and the vehicle, such as incorrect offset alignment, problems such as overcurrent can occur.
[0034] In view of the problems existing in the related art, the present disclosure provides a vehicle charging method, which is applied to a vehicle. Figure 1 is a flow chart showing a vehicle charging method according to an exemplary embodiment. Figure 1 As shown, the method may include at least the following steps: Step S110 . Obtain an identity authentication result, where the identity authentication result is used to indicate whether the charging device can charge the vehicle with a current value greater than a target current limit value, where the target current limit value is a current limit value corresponding to a specified charging standard.
[0035] Step S120: Send a feedback message, and charge with the current value according to the identity verification result and the feedback message. The feedback message is used to respond to the verification message corresponding to the current value sent by the charging device.
[0036] In the exemplary embodiments of the present disclosure, an authentication system for charging devices is added based on identity verification results. This eliminates unauthenticated charging devices and ensures charging safety from the charging device side. Furthermore, by sending a feedback message in response to a verification message corresponding to a current value greater than the target current limit, protocol development for both the vehicle and the charging device is reduced, enabling high-current charging without requiring software changes in either the vehicle or the charging device, and improving compatibility and scalability.
[0037] The following describes in detail the various steps of the vehicle charging method.
[0038] In step S110 , an identity authentication result is obtained, where the identity authentication result is used to indicate whether the charging device can charge the vehicle with a current value greater than a target current limit value, where the target current limit value is a current limit value corresponding to a specified charging standard.
[0039] In an exemplary embodiment of the present disclosure, the identity verification result may be sent by the cloud, and the cloud determines the identity verification result in the following manner: Figure 3 As shown, no further details are given here.
[0040] In step S120, a feedback message is sent, and charging is performed with the current value according to the identity authentication result and the feedback message. The feedback message is used to respond to the verification message corresponding to the current value sent by the charging device.
[0041] In an exemplary embodiment of the present disclosure, when the charging device is a charging pile, the charging pile can initiate a protocol handshake message to the vehicle as a verification message when starting charging. When the vehicle determines that the verification message carries a message with the SC1 flag (i.e., SPN2600 == SC1), it indicates that the vehicle has determined that the verification message sent by the charging pile corresponds to the current value. Therefore, it can send a corresponding feedback message to the charging device to complete the protocol handshake.
[0042] When the vehicle's identity authentication result shows that the charging device can charge the vehicle at a current value greater than the target current limit, and a feedback message is sent to the charging pile according to the verification message corresponding to the current value, it can be determined that the vehicle can be charged at this current value.
[0043] Among them, the target current limit can be the maximum current value of 400A in the national standard, and the current value that can charge the vehicle can be 600A, 800A, or any current value between 2000A. The current value can also be determined to be a current value exceeding 2000A based on actual conditions. This exemplary embodiment does not make any special limitations on this.
[0044] In an optional embodiment, communication with the terminal device is performed by means of a short-range wireless connection.
[0045] The terminal device may be a mobile phone or other device that has a vehicle APP (Application) logged in, and this exemplary embodiment does not specifically limit this. The short-range wireless connection method may be a Bluetooth connection or other connection methods, and this exemplary embodiment does not specifically limit this.
[0046] The user of the vehicle completes the binding in the car APP, and completes the Bluetooth digital key connection between the car APP and the bound vehicle. At the same time, when using the car APP to scan the code to start the charging pile, keep the mobile phone Bluetooth on. The purpose of keeping Bluetooth on is to ensure the digital Bluetooth connection between the vehicle and the mobile phone APP, so that the identity of the vehicle that currently needs to be charged can be identified. Among them, the identity of the vehicle is confirmed by the vehicle VIN (Vehicle Identification Number). This solution can ensure the uniqueness of the vehicle currently used to scan the code to start charging with the car APP, and avoid the problem of not being able to send the corresponding vehicle in the scenario of multiple vehicles under a single car APP account. Through Bluetooth near-field communication, the problem of sending the identification result to a vehicle in another place when the car APP scans the code to start is also solved.
[0047] In an alternative embodiment, Figure 2 FIG. 1 shows a flow chart of a method for charging according to a target current limit. Figure 2 As shown, the method may at least include the following steps: in step S210, when no identity authentication result is obtained, charging is performed at the target current limit.
[0048] When a phone's Bluetooth is turned off, the VIN of a nearby vehicle cannot be retrieved, preventing the car's app from uploading the vehicle's VIN to the cloud. Consequently, the cloud cannot transmit the authentication result to the vehicle after confirming the charging device's authentication. Therefore, when the vehicle cannot receive the authentication result from the cloud, it can charge at the target current limit. Typically, this target current limit is 400A, as specified by the national standard.
[0049] In step S220 , when a verification message not corresponding to the current value is received, charging is performed at the target current limit.
[0050] When the charging pile sends a verification message to the vehicle, in addition to the message carrying the flag bit SC1, it can also be a message with the flag bit 0101 or other content. At this time, it indicates that the verification message is not a verification message corresponding to the current value. Therefore, the vehicle is charged according to the target current limit.
[0051] In step S230 , when the identity authentication result is that the charging device cannot charge the vehicle with a current value greater than the target current limit, charging is performed at the target current limit.
[0052] When the authentication result sent from the cloud indicates that the charging device cannot charge the vehicle at a current greater than the target current limit, the vehicle is charged according to the target current limit of 400A specified in the national standard.
[0053] In an exemplary embodiment of the present disclosure, another vehicle charging method is also provided, which is applied to the cloud. Figure 3is a flow chart showing another vehicle charging method according to an exemplary embodiment. Figure 3 As shown, the method may include at least the following steps: In step S310, the device identification information of the charging device and the vehicle identification information of the vehicle are obtained, and the authentication result of the charging device is determined based on the device identification information. The authentication result is used to indicate whether the charging device can charge the vehicle with a current value greater than a target current limit value. The target current limit value is the current limit value corresponding to the specified charging standard.
[0054] In the exemplary embodiments of the present disclosure, the device identification information can be the ID (identity document) of a charging device, such as a charging station, or other information, which is not specifically limited in this exemplary embodiment. The cloud can obtain the device identification information by, for example, scanning the charging station's QR code with a car app and parsing the QR code to obtain the charging station ID.
[0055] The vehicle identification information may be the vehicle's VIN information or other information, which is not specifically limited in this exemplary embodiment. The cloud may obtain the vehicle identification information by uploading the vehicle's VIN information obtained via Bluetooth connection to the cloud via the vehicle APP.
[0056] In an optional embodiment, device information is obtained and stored.
[0057] Because the cloud is interconnected with the charging pile cloud, it can obtain device information of the charging device from the charging pile. This device information is related to a pre-defined charging pile whitelist. The charging pile whitelist is a list of charging devices that are allowed to charge the vehicle at a current value greater than the target current limit.
[0058] Furthermore, the cloud can store the acquired device information in a database as a basis for determining the authentication result of the charging device.
[0059] In an alternative embodiment, Figure 4 A flow chart showing a method for determining an identity verification result is shown in FIG. Figure 4 As shown, the method may include at least the following steps: In step S410, the device brand information of the charging device is determined according to the device identification information.
[0060] When the whitelist of charging piles is defined by device brand information, the device brand information of the charging device can be queried based on the device identification information.
[0061] In step S420, the device brand information is queried in the device information to obtain the authentication result of the charging device.
[0062] Furthermore, the device information is queried to determine whether the device brand information corresponding to the charging device exists, thereby obtaining an authentication result for the charging device. If the device brand information corresponding to the charging device can be found in the device information, the authentication result indicates that the charging device can charge the vehicle at a current greater than the target current limit. If the device brand information corresponding to the charging device cannot be found in the device information, the authentication result indicates that the charging device cannot charge the vehicle at a current greater than the target current limit and should charge the vehicle at the target current limit.
[0063] In step S320, the identity authentication result is sent according to the vehicle identification information so that the vehicle is charged according to the current value.
[0064] In an exemplary embodiment of the present disclosure, after determining the identity authentication result of the charging device, the identity authentication result may be sent to the corresponding vehicle according to the identity identification information to instruct the vehicle to charge according to the current value.
[0065] In an optional embodiment, when the vehicle identification information is not obtained, the identity authentication result is not sent.
[0066] If the phone's Bluetooth is turned off, the VIN of nearby vehicles cannot be obtained, resulting in the cloud being unable to obtain the vehicle's VIN through the car app upload. Therefore, the authentication result cannot be sent according to the vehicle's VIN, and the authentication result will not be sent.
[0067] In an optional embodiment, when the identity authentication result is that the charging device cannot charge the vehicle at a current value greater than the target current limit, the identity authentication result is sent according to the vehicle identification information so that the vehicle is charged according to the target current limit.
[0068] When the authentication result sent from the cloud indicates that the charging device cannot charge the vehicle at a current greater than the target current limit, the vehicle is charged according to the target current limit of 400A specified in the national standard.
[0069] In an exemplary embodiment of the present disclosure, another vehicle charging method is provided, which is applied to a charging device. Figure 5 is a flow chart of another vehicle charging method according to an exemplary embodiment. Figure 5 As shown, the method may include at least the following steps: In step S510 , a verification message is sent, the verification message corresponds to a current value greater than a target current limit, and the target current limit is a current limit corresponding to a specified charging standard.
[0070] In an exemplary embodiment of the present disclosure, the charging device may include a charging station or other device for charging a vehicle. When the charging station initiates charging, it may send a protocol handshake message to the vehicle as a verification message. This verification message may carry a flag bit SC1, indicating that the vehicle can be charged at a current greater than the target current limit.
[0071] In step S520, a feedback message corresponding to the verification message sent by the vehicle is received, and the vehicle is charged with the current value according to the feedback message.
[0072] When the vehicle determines that the verification message carries a message with the flag bit SC1, it indicates that the vehicle determines that the verification message sent by the charging pile is a message corresponding to the current value. Therefore, the vehicle can send a corresponding feedback message to the charging device to complete the protocol handshake.
[0073] After receiving the feedback message sent by the vehicle, the charging device can charge the vehicle according to the instruction of the feedback message at a current value greater than the target current limit.
[0074] In an optional embodiment, when a verification message that does not correspond to the current value is sent, the vehicle is charged at the target current limit according to the received feedback message.
[0075] When the charging station starts charging, it can send a protocol handshake message to the vehicle as a verification message. This verification message can carry a flag bit of 0101, etc., indicating that the vehicle cannot be charged at a current value greater than the target current limit. Therefore, upon receiving this verification message, the vehicle can be charged at the target current limit.
[0076] The vehicle charging method in the embodiment of the present disclosure is described in detail below with reference to an application scenario.
[0077] Figure 6 The schematic diagram of the vehicle charging system in the application scenario is shown in FIG. Figure 6 As shown, charging is initiated by scanning the charging station's QR code through the car app. The app provides the charging station ID obtained through the scan and the VID of the vehicle connected to the phone to the cloud. The cloud then determines whether the charging station is a whitelisted brand based on the charging station ID. If it is, the cloud sends the whitelist result to the vehicle connected to the phone. Upon receiving the whitelist result, the vehicle's charging controller responds to the group standard handshake initiated by the charging station, enabling high-current charging.
[0078] Among them, the charging pile cloud and the cloud end communicate through the public network, and the cloud end and the car APP also communicate through the public network. The car APP and the vehicle are connected through Bluetooth, the cloud end and the vehicle communicate through 5G (the 5th generation mobile networks, fifth generation mobile communication technology), the vehicle and the charging pile communicate through CAN, and the charging pile and the charging pile cloud communicate through 4G (the 4th Generation mobile communication technology, fourth generation mobile communication technology), 5G or Wi-Fi (wireless network communication technology).
[0079] In this application scenario, the car user completes the binding in the car APP and completes the Bluetooth digital key connection between the Xiaomi Auto APP and the bound vehicle. At the same time, when using the car APP to scan the code to start the charging pile, keep the mobile phone Bluetooth on.
[0080] Keeping Bluetooth enabled ensures a digital Bluetooth connection between the vehicle and the mobile app, allowing the identification of the vehicle currently in need of charging to be confirmed by its VIN. This ensures the uniqueness of the vehicle currently being used to initiate charging by scanning the QR code on the car app, thus avoiding the issue of being unable to send the corresponding vehicle when multiple vehicles are connected to a single car app account. Bluetooth near-field communication also solves the problem of sending the identification result to a vehicle in a different location when the car app scans the QR code to initiate charging.
[0081] The cloud obtains charging pile data by interconnecting with the charging pile cloud, including attribute information such as the charging pile's ID and brand. The cloud further stores the charging pile data in a database. The charging pile can be started by scanning the code through the car APP to realize charging start control.
[0082] The judgment and result of the charging pile brand whitelist is to use the car APP to scan the startup QR code of the interconnected charging pile, obtain the ID of the charging pile through the QR code information, and at the same time, the car APP sends the vehicle VIN obtained through the Bluetooth connection to the cloud. The cloud queries the brand of the charging pile in the database based on the charging pile ID, and determines whether this charging pile brand belongs to the whitelist. If it belongs to the whitelist brand, the cloud will send the corresponding whitelist result to the charging controller of the corresponding vehicle provided by the car APP. Among them, the charging pile whitelist brand rules can be customized, and can define charging pile brands that have completed interconnection, charging pile brands that have passed the group standard protocol test, or charging pile brands that have passed the high-current performance test, etc. This exemplary embodiment does not make special restrictions on this.
[0083] Among them, if the VIN of a nearby vehicle cannot be obtained due to the Bluetooth of the mobile phone being turned off, the car APP will not provide the VIN information, but only provide the charging pile ID information to the cloud. If the cloud cannot obtain the vehicle VIN, the whitelist result will not be issued; or if the charging pile brand is not on the whitelist according to the charging pile ID obtained by the car APP, the cloud will issue a result that does not comply with the whitelist configuration.
[0084] After plugging in the charger, the vehicle charging controller checks whether the cloud has issued a whitelist result. After the charging station starts charging, it initiates a protocol handshake. When the vehicle charging controller recognizes the charging station initiating a group standard protocol handshake, it determines that the cloud has also issued a whitelist brand. It then responds to the group standard protocol handshake initiated by the charging station, and the vehicle enters the group standard protocol charging phase. The charging controller follows the group standard protocol, changing the maximum charging current limit from the national standard 400A to 2000A, or other current values greater than 400A, thereby achieving high-current charging beyond the national standard protocol.
[0085] If the charging pile starts charging and initiates a protocol handshake message, the vehicle charging controller does not receive the charging pile whitelist brand from the cloud or receives the charging pile whitelist brand result sent by the cloud, but the charging handshake message after the charging pile is started is not a group standard protocol, the vehicle charging controller responds to the charging pile according to the national standard protocol, and thus charges according to the national standard protocol.
[0086] Figure 7 The interactive flow chart of the vehicle charging method in the application scenario is shown as follows: Figure 7 As shown, first, obtain the charging pile ID and vehicle VIN.
[0087] When charging at the charging pile, the car APP scans the charging pile QR code. The car APP parses the charging pile ID based on the QR code and packages it together with the vehicle VIN and sends it to the cloud.
[0088] Then, the charging pile brand whitelist is identified and the results are issued.
[0089] The cloud uses the charging pile ID and the scanned vehicle VIN provided by the car app to query the charging pile brand in the database and determine whether it is a whitelisted brand. If the charging pile ID is identified as a whitelisted brand, the corresponding result is sent to the vehicle charging controller.
[0090] Finally, the vehicle charging process response and control.
[0091] After the gun is plugged in, the charging pile receives the charging start instruction from the charging pile cloud and sends a group standard protocol handshake. The vehicle detects the group standard protocol and receives the charging pile whitelist brand result from the cloud. The vehicle responds to the group standard protocol and enters the group standard high-current charging.
[0092] In the exemplary embodiments of the present disclosure, compared with private protocols, the vehicle-charging pile part of this technical solution is based on group standards, which does not require the development of customized private protocols for vehicles and charging piles, reduces the development of vehicle-charging pile protocols, improves charging compatibility, and can achieve automatic compatibility with charging piles that support group standards, with better scalability.
[0093] Compared with the scheme that only has group labels for vehicles and charging piles, this technical solution proposes an identity recognition scheme, whereby charging piles and vehicles can be tested first, and the functional and performance tests are passed to ensure charging safety.
[0094] Based on this, this technical solution does not use a private protocol to achieve high-current charging, which reduces vehicle protocol development, has simple logic, and improves vehicle charging compatibility.
[0095] Compared with the vehicle directly charging with the charging pile that supports the group standard protocol, this technical solution adds charging pile identification and can exclude charging piles that have not passed the test to ensure charging safety.
[0096] This technical solution uses cloud-based identification and does not require vehicle software changes. If the charging pile meets the whitelist conditions, high-current charging can be achieved after configuration is completed in the cloud.
[0097] This technical solution does not require the charging pile to change the software, the charging pile has better compatibility, and it is easier to promote limited high-current cooperation.
[0098] In addition, in an exemplary embodiment of the present disclosure, a first vehicle charging device is further provided, which is applied to a vehicle.
