Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a method, apparatus, storage medium, and vehicle for charging a vehicle. Background Technology

[0002] With the rapid development of new energy vehicles, a large number of public charging facilities, such as public charging piles, have been installed in public places to meet users' charging needs. Currently, before users can charge their new energy vehicles using public charging piles, they need to scan a QR code to register or activate a charging mini-program. First-time users also need to complete several preparatory steps, including connecting the charging gun, scanning the QR code, registering, logging in, and making a payment via QR code.

[0003] After the vehicle connects to a public charging station, the battery management system (BMS) sends a charging enable signal to the charging station. Following this signal, the BMS begins a diagnostic timer. If the user completes the preparation within the diagnostic time, the BMS will switch to fast charging mode and begin charging. If the user does not complete the preparation within the diagnostic time, the vehicle will stop charging, and the user will need to reconnect to the public charging station and complete the preparation process again. Currently, the diagnostic time for most new energy vehicles on the market is relatively short, typically around one minute, which cannot meet the user's need to complete the preparation process. This forces users to repeatedly complete the preparation process, wasting time, which is unreasonable. Summary of the Invention

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0035] When the battery charge level drops to a first threshold, the battery management system will send a request to the user that the battery is low and needs to be charged. After receiving the request from the battery management system, the user can find a charging station to charge the vehicle using the "charging station search" function on the vehicle or by using map navigation.

[0036] "Charging station search" refers to the on-board controller finding charging stations that match the user's input criteria in a charging station distribution map and navigating the user to the target charging station. The user's input criteria can include the brand of the charging station, distance, or price.

[0037] The first aspect of the present invention provides an embodiment, Figure 1 A flowchart illustrating a vehicle charging method is shown, specifically including:

[0038] Step S101: Identify the brand of the charging device;

[0039] Currently, charging stations installed in public places are provided by multiple brands. Users need to register accounts or complete security authentication on different applications or platforms when using charging stations from different brands. Even within the same brand, the authentication process differs for vehicles charging for the first time and those charging for the first time, with the latter requiring more steps. Therefore, the battery management system needs to first identify the brand of the charging station to differentiate between brands used for first-time charging and those used for subsequent charging, allowing for different measures to be taken for different brand categories of charging stations.

[0040] Step S102: Determine the diagnostic time of the battery management system based on the brand of the charging device;

[0041] Since the certification process for vehicles charging for the first time and vehicles charging for the first time differs for the same brand of charging device, the time required for users to complete the certification process and other preparations also varies. Therefore, after classifying charging device brands into first-time charging brands and non-first-time charging brands, users can be given different lengths of diagnostic time according to different brand categories to ensure that users have sufficient time to complete the preparation work.

[0042] Step S103: If the diagnostic time has not ended and a signal indicating that the charging device agrees to supply power is received, the current supplied by the charging device is received to charge the vehicle.

[0043] After the user completes the preparation work within the diagnostic time, the charging device will send a signal to the battery management system agreeing to supply power and start supplying power to the vehicle. After receiving the signal from the charging device agreeing to supply power, the battery management system will receive the current supplied by the charging device, and the vehicle will start charging.

[0044] The second aspect of the present invention provides an embodiment, Figure 2 The diagram illustrates the steps of another vehicle charging method, specifically including:

[0045] Step S201: Receive a brand category signal from the charging device, and identify the brand of the charging device based on the brand category signal;

[0046] Once the charging device establishes a circuit connection with the vehicle, it sends a signal to the battery management system, including information such as brand category. The battery management system can then identify the brand category from the signal and determine it as the brand category of the charging device.

[0047] Step S202: Match the location coordinates of the vehicle with the location coordinates of the charging device in the charging device distribution map. When there is a first charging device in the charging device distribution map with the same location coordinates as the vehicle, determine the brand of the first charging device as the brand of the charging device.

[0048] The charging device distribution map is a schematic diagram showing the distribution of charging devices on a map, including their location coordinates and brand categories. After a user finds a charging device using the "Find a Charging Station" function or map navigation and arrives at the target charging device, the vehicle controller matches the vehicle's current location coordinates with the location indicators of the charging device on the charging device distribution map. If a first charging device with the same location coordinates as the vehicle exists on the distribution map, it is identified as the target charging device for the vehicle, and its brand is also identified as the brand of the target charging device.

[0049] The battery management system can select either step S201 or step S202 to identify the brand of the charging device, depending on different application scenarios and needs. For example, when the signal sent by the charging device does not include brand information, step S202 can be used for identification; when the vehicle positioning system is inaccurate, step S201 can be used for identification. Furthermore, steps S201 and S202 can also be used simultaneously to identify the brand of the charging device, and the results of steps S201 and S202 can be compared to improve the accuracy of the battery management system in identifying the brand of the charging device.

[0050] Step S203: After identifying the brand of the charging device, the brand category is determined as either a first-time charging brand or a non-first-time charging brand based on the vehicle's historical charging records, which include brand category information; when the brand category is the first-time charging brand, the diagnosis time is the first time; when the brand category is the non-first-time charging brand, the diagnosis time is the second time.

[0051] When a vehicle is charging, the battery manager records information such as the amount of charge, charging time, and the brand of the charging device, creating a historical charging record. Brands of the target charging device not recorded in the historical charging record are referred to as first-time charging brands, while those recorded are referred to as non-first-time charging brands.

[0052] After the battery management system identifies the brand of the charging device, it categorizes the brand into first-time charging brands or non-first-time charging brands based on whether it is recorded in the historical charging records, and gives each brand a corresponding length of diagnostic time.

[0053] When the brand category is the brand being charged for the first time, the battery management system determines the diagnostic time as the first time; when the brand category is the brand not being charged for the first time, the battery management system determines the diagnostic time as the second time. The lengths of the first and second times can be determined as a fixed value or by the battery management system based on the user's required diagnostic time from historical charging records, with the first time being longer than the second time.

[0054] Step S204: After the charging device and the vehicle form a circuit connection, a charging enable signal is sent to the charging device. The charging enable signal is used to request charging current from the charging device. After sending the charging enable signal and identifying the brand category, a timer is started to determine whether the diagnostic time has ended.

[0055] After the charging device and the vehicle form a circuit, the battery management system determines the current required by the vehicle based on the current temperature or other conditions, and sends it to the charging device in the form of a charging enable signal. In turn, it requests the charging current from the charging device so that the charging device can supply power to the vehicle according to the current required by the vehicle.

[0056] Once the battery management system sends a charging enable signal and identifies the brand and category of the charging device, it begins diagnostic timing. At this time, the user can prepare to use the charging device on the relevant management platform so that the charging device can send a signal to the battery management system agreeing to supply power after the user's preparation is completed.

[0057] When the diagnostic time ends and no signal of consent to power supply from the charging device is received, proceed to step S205; when the diagnostic time has not ended and a signal of consent to power supply from the charging device is received, proceed to step S206.

[0058] Step S205: If the diagnostic time ends and no signal of consent to power supply from the charging device is received, a timeout reminder message is sent to the user.

[0059] After the user completes the authentication process for using the charging device, the charging device will send a signal to the battery management system (BMS) indicating that it agrees to supply power. If the diagnostic timer expires but the BMS has not received the signal from the charging device, it indicates that the user has not completed the authentication process within the diagnostic time, and the BMS will send a timeout message to the user.

[0060] Furthermore, the battery management system can collect relevant data on user timeouts and learn from the timeout data using machine learning algorithms and other tools to automatically allocate different lengths of diagnostic time for different users.

[0061] Step S206: If the diagnostic time has not ended and a signal indicating that the charging device agrees to supply power is received, the current supplied by the charging device is received to charge the vehicle.

[0062] If the diagnostic timer has not ended and the battery management system receives a signal from the charging device agreeing to supply power, it indicates that the user has completed the authentication process within the diagnostic time, and the charging device will supply power to the vehicle according to the current requested by the battery management system.

[0063] The third aspect of the present invention provides an embodiment, Figure 3 A flowchart illustrating a vehicle charging scenario is shown, specifically including:

[0064] Once the user finds a charging station through "charging station search" or map navigation, they connect the charging gun of the charging station to the vehicle's charging port to create a circuit between the vehicle and the charging station.

[0065] Once the Battery Management System (BMS) detects that the charging gun is connected to the charging port, it sends a charging enable signal to the charging station to request charging current. Simultaneously, the BMS can identify the brand of the charging station by receiving brand information from it, or by matching the vehicle's location coordinates with the charging gun's location coordinates on the charging gun distribution map using the onboard controller. For details, please refer to steps S201 and S202 regarding the identification of the charging device brand.

[0066] After identifying the brand of the charging station, the system compares the brand of the charging station with the vehicle's historical charging records to determine whether the vehicle is using the brand for the first time. If it is determined that the vehicle is using the brand's charging station for the first time, the battery management system assigns a diagnostic time of 10 minutes; if it is determined that the vehicle is not using the brand's charging station for the first time, the battery management system assigns a diagnostic time of 5 minutes.

[0067] After the battery management system (BMS) sends a charging enable signal to the charging station and completes the diagnostic timer, the BMS begins the diagnostic timer. During the diagnostic time, the user can prepare to use the charging station on the charging station management platform, so that the charging station can send a signal to the BMS indicating that it agrees to supply power after the preparation is complete.

[0068] When the diagnostic timer has not ended and the battery management system receives a signal from the charging pile agreeing to supply power, the battery management system receives the current supplied by the charging pile, and the vehicle begins to receive power.

[0069] When the diagnostic timer expires and the battery management system has not received a signal from the charging station agreeing to supply power, the battery management system sends a timeout reminder to the user.
