[0028] It should be understood that the term "and / or" as used herein simply describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. Furthermore, the character " / " in this document generally indicates an "or" relationship between the associated objects.

[0029] With the country's vigorous promotion and the improvement of public environmental awareness, new energy electric vehicles are gradually favored by more and more consumers due to their advantages of energy saving and environmental protection, and are entering thousands of households.

[0030] Currently, electric vehicles on the market offer two charging methods: wired charging and wireless charging. Wired charging presents numerous challenges, including inflexible charging, aging cables, and safety concerns caused by dragging cables. Wireless charging technology addresses these issues. When an electric vehicle is parked in a location equipped with a wireless charging system, the battery can begin charging. However, existing wireless charging for electric vehicles still requires remote activation of the wireless charging station after parking, failing to achieve full intelligent functionality. Furthermore, the wireless charging system operates continuously, regardless of whether a vehicle is parked in the parking space equipped with the wireless charging station. This results in energy loss and poses safety risks.

[0031] To address the above-mentioned issues, embodiments of the present application provide a vehicle charging method, apparatus, device, and storage medium to address the above-mentioned issues. The inventive concept of this application can be summarized as follows: controlling the power battery in the vehicle to discharge the on-board receiving terminal; causing the on-board receiving terminal to generate a magnetic field based on the discharge operation; using the magnetic field to cause the ground transmitting terminal to generate a wake-up signal, which is used to wake up the wireless charging system; establishing a communication connection with the wireless charging system; receiving a charging signal sent by the wireless charging system based on the communication connection; and closing a charging relay based on the charging signal.

[0032] In an embodiment of the present application, when the vehicle needs to be charged, the vehicle actively interacts with the wireless charging system by discharging. The wireless charging system will be awakened and enter the working state only after receiving the wake-up signal. The wireless charging system will not enter the working state before receiving the wake-up signal, thereby reducing energy consumption, reducing the safety hazards caused by the wireless charging system being in the working state all the time, and improving the safety of the wireless charging system.

[0033] For ease of understanding, a vehicle charging method provided by an embodiment of the present application is described in detail below with reference to the accompanying drawings: like Figure 1 The figure shows an application scenario diagram of a vehicle charging method in an embodiment of the present application. The figure includes: a vehicle 10, a wireless charging system 20; wherein: The vehicle 10 controls the power battery to discharge the on-board receiving terminal; so that the on-board receiving terminal generates a magnetic field based on the discharge operation; the magnetic field is used to cause the ground transmitting terminal to generate a wake-up signal, and the wake-up signal is used to wake up the wireless charging system 20; the vehicle 10 establishes a communication connection with the wireless charging system 20; the vehicle 10 receives the charging signal sent by the wireless charging system 20 based on the communication connection; the vehicle 10 closes the charging relay based on the charging signal to charge.

[0034] The description in this application details only a single vehicle 10 and wireless charging system 20. However, those skilled in the art will appreciate that the illustrated vehicle 10 and wireless charging system 20 are intended to illustrate the operation of the vehicle 10 and wireless charging system 20 involved in the technical solution of this application. This does not imply any limitation on the number, type, or location of vehicles 10 and wireless charging systems 20. It should be noted that adding additional modules to the illustrated environment or removing individual modules from it does not change the underlying concepts of the exemplary embodiments of this application.

[0035] It should be noted that the battery system control method proposed in this application is not only applicable to Figure 1 The application scenario shown is also applicable to any device that requires vehicle charging.

[0036] like Figure 2 FIG. 1 is a flow chart of the interaction between a vehicle and a wireless charging system in a vehicle charging method provided by an embodiment of the present application, wherein: In step 201: the vehicle receives a parking command triggered by the user, and controls the vehicle to park at a target parking position based on the parking command; a wireless charging system is set in the target parking position, and the wireless charging system includes a ground transmitter.

[0037] In an embodiment of the present application, when a user needs to charge, he or she can trigger a parking command through a mobile terminal or a remote control key or other device. After receiving the parking command, the vehicle controls the vehicle to park at the target parking location according to the parking command.

[0038] For example: Figure 3As shown, the user selects parking space 1 as the target parking location on the mobile phone, generates a parking instruction based on the target parking location selected by the user, and the mobile phone sends the parking instruction to the vehicle associated with the mobile phone. After receiving the parking instruction, the vehicle parks in parking space 1; a wireless charging system is provided in parking space 1, and a ground transmitting terminal is provided in the wireless charging system.

[0039] In step 202: the vehicle obtains the battery power, battery temperature and electronic parking brake status of the vehicle.

[0040] In an embodiment of the present application, in order to ensure the safety of the vehicle during charging, a charging self-test operation needs to be performed on the vehicle before charging the vehicle. Only after it is determined that the vehicle has passed the charging self-test operation will the subsequent steps be implemented.

[0041] In the embodiments of the present application, it is considered that charging a battery in a vehicle when the battery level is too high will accelerate the speed of the chemical reaction inside the battery, causing damage to the internal structure of the battery, thereby reducing the service life of the battery; and overcharging will significantly increase the load on the battery, resulting in a shortened battery life and a gradual decline in performance. Therefore, it is necessary to obtain the battery level of the vehicle when performing a charging self-test operation on the vehicle; Secondly, charging when the battery temperature is too high may cause the electrolyte to decompose, which will in turn damage the battery life and performance. Charging at high temperatures will also accelerate the chemical reaction inside the battery, causing the battery capacity to drop rapidly, affecting the vehicle's range. Therefore, it is necessary to obtain the vehicle's battery temperature during the vehicle charging self-test operation; Finally, when the vehicle's electronic parking brake is not in the parking state, it may slip down a slope, which may easily cause an accident. Therefore, the vehicle's electronic parking brake status must be obtained when performing the vehicle's charging self-test.

[0042] It can be understood that the three parameters that need to be obtained during the charging self-test operation given above are only an embodiment, and do not limit the number of parameters that need to be obtained during the charging self-test operation. In specific implementation, at least one or any combination of the above three parameters can be obtained, and other parameters related to the safety of the vehicle during the charging process can also be obtained.

[0043] In step 203: the vehicle performs a charging self-check operation on the vehicle according to the battery power, battery temperature and electronic parking brake status of the vehicle.

[0044] In an embodiment of the present application, in order to ensure the safety of the vehicle during charging, a charging self-test operation needs to be performed on the vehicle before charging the vehicle. Only after it is determined that the vehicle has passed the charging self-test operation will the subsequent steps be implemented.

[0045] Specifically, it can be implemented as follows: judge the vehicle's battery power, battery temperature and electronic handbrake status. If the battery power is less than the preset power, the battery temperature is lower than the preset battery temperature, and the electronic handbrake status is in the parking state, it is determined that the vehicle charging self-test operation has passed; if the battery power is greater than or equal to the preset power, or the battery temperature is greater than or equal to the preset battery temperature, or the electronic handbrake status is not in the parking state, it is determined that the vehicle has not entered the charging state.

[0046] That is, in the embodiment of the present application, the vehicle charging self-test operation is determined to have passed only when it is determined that the vehicle's battery power is too low, the battery temperature is low, and the vehicle is in the parking state. If any one of these conditions is not met, it is determined that the vehicle has not entered the charging state.

[0047] The preset power level may be any value between 30% and 50% of the power level, and the preset battery temperature may be set to 60 degrees Celsius.

[0048] It can be understood that the specific values ​​of the preset power and preset battery temperature given in this application are only an embodiment, and do not limit the specific values ​​of the preset power and preset battery temperature. During specific implementation, technical personnel can set the values ​​of the preset power and preset battery temperature according to their needs.

[0049] In some possible embodiments, when the vehicle is not in the charging state, in order to facilitate the user to promptly understand the reason why the vehicle is not in the charging state, the following may be implemented: Figure 4 The steps shown, where: In step 401: if it is determined that the vehicle has not entered the charging state, the reason why the vehicle has not entered the charging state is determined.

[0050] In an embodiment of the present application, when the vehicle fails the charging self-test operation, the condition that the vehicle does not meet is regarded as the reason why the vehicle does not enter the charging state.

[0051] For example: if it is determined that the vehicle's battery power is less than a preset power level, the vehicle's battery temperature is lower than a preset battery temperature, and the vehicle's electronic parking brake is not in the parking state, then it can be determined that the reason the vehicle failed the charging self-test operation is that the electronic parking brake was not in the parking state.

[0052] It is understandable that when the vehicle does not meet multiple conditions, the multiple conditions are simultaneously used as reasons why the vehicle does not enter the charging state.

[0053] For example: if it is determined that the vehicle's battery power is less than a preset power level, the vehicle's battery temperature is higher than a preset battery temperature, and the vehicle's electronic parking brake is not in the parking state, it can be determined that the reason why the vehicle failed the charging self-test operation is: the battery temperature is higher than the preset battery temperature and the electronic parking brake is not in the parking state.

[0054] In step 402 : Based on the reason why the vehicle has not entered the charging state, a first prompt is generated.

[0055] In an embodiment of the present application, a first prompt is generated to make the user aware of the reason why the vehicle has not entered the charging state, wherein the first prompt can be in the form of a prompt box or a voice prompt, which is not limited in the present application.

[0056] In step 403: a first prompt is displayed; the first prompt is used to inform the user why the vehicle has not entered the charging state.

[0057] In an embodiment of the present application, the first prompt can be displayed on the vehicle display screen, or the first prompt can be voice broadcast through a voice playback device in the vehicle; or after the first prompt is generated, the first prompt is sent to a mobile terminal associated with the vehicle.

[0058] For example, if the reason why the vehicle failed the charging self-test is that the electronic parking brake was not in the parking state, the following will be displayed on the vehicle display: Figure 5 The prompt box shown can help users intuitively understand the reason why the vehicle failed the charging self-test operation, and then adjust the status of the electronic parking brake to enable the vehicle to pass the charging self-test operation.

[0059] In step 204: when the vehicle passes the charging self-test operation, a wireless charging wake-up instruction is generated.

[0060] In an embodiment of the present application, after the vehicle passes the charging self-test operation, in order to facilitate interaction between various components of the vehicle, the entire vehicle system can interact with the battery management system through wireless charging wake-up instructions.

[0061] In step 205: the vehicle controls the power battery in the vehicle to discharge the on-board receiving end based on the wireless charging wake-up instruction; so that the on-board receiving end generates a magnetic field based on the discharge operation; the magnetic field is used to cause the ground transmitting end to generate a wake-up signal, and the wake-up signal is used to wake up the wireless charging system.

[0062] In the embodiments of this application, Figure 6 As shown, after receiving the wireless charging wake-up command sent by the vehicle system, the battery management system in the vehicle controls the power battery to discharge the on-board receiving end. The coil in the on-board receiving end generates a magnetic field based on the current, and the coil in the ground transmitting end will be affected by the magnetic field, thereby generating a wake-up signal.

[0063] In step 206 : the wireless charging system generates a wake-up signal; the wake-up signal is generated based on a magnetic field, and the magnetic field is generated by the on-board receiving terminal in the vehicle based on a discharge operation.

[0064] In an embodiment of the present application, the wireless charging system includes a ground transmitting end, and the coil in the ground transmitting end generates a wake-up signal after being affected by the magnetic field; the wake-up signal user wakes up the wireless charging system so that the wireless charging system enters a state where it can wirelessly charge the vehicle.

[0065] In some possible embodiments, in order to ensure safety during the charging process, the wireless charging system needs to perform a charging self-test after being awakened. Only after the charging self-test passes will the subsequent steps be implemented. Specifically, it can be implemented as follows: obtaining the status of the hardware device and the temperature of the hardware device; if the status of the hardware device is normal and the temperature of the hardware device is lower than the preset temperature, a charging signal is sent to the vehicle based on the communication connection.

[0066] In the embodiment of the present application, considering that if there is an abnormal hardware device in the wireless charging system, it will cause a safety hazard in the charging process, or it will cause the vehicle to be unable to be charged, it is necessary to judge the status of each hardware device in the wireless charging system; secondly, when there is a hardware device with an overly high temperature in the wireless charging system, it will cause the charging process to be slower and there will be a safety hazard, so it is also necessary to judge the temperature of each hardware device.

[0067] It is understandable that when the wireless charging system performs a charging self-test, other parameter information may also be judged, and this application does not limit this.

[0068] In step 207: the vehicle establishes a communication connection with the wireless charging system.

[0069] In the embodiment of the present application, in order to facilitate the interaction between the vehicle and the wireless charging system, the vehicle establishes a communication connection with the wireless charging system.

[0070] In some possible embodiments, the manner in which the vehicle establishes a communication connection with the wireless charging system includes, but is not limited to, a wireless network, a Bluetooth method, and the like.

[0071] In step 208 : the wireless charging system sends a charging signal to the vehicle based on the communication connection.

[0072] In the embodiment of the present application, in order to facilitate the vehicle to receive charging, after establishing the communication connection, the wireless charging system sends a charging signal to the vehicle to prepare for charging.

[0073] In step 209 : the charging relay is closed based on the charging signal.

[0074] In an embodiment of the present application, after receiving a charging signal, the vehicle performs wireless charging by closing a charging relay.

[0075] To sum up, in the embodiment of the present application, when the vehicle needs to be charged, the vehicle actively interacts with the wireless charging system by discharging. The wireless charging system will be awakened only after receiving the wake-up signal and then enter the working state. The wireless charging system will not enter the working state before receiving the wake-up signal, which reduces energy consumption and reduces the safety hazards caused by the wireless charging system being in the working state all the time, thereby improving the safety of the wireless charging system.

[0076] like Figure 7 FIG. 1 is a schematic diagram of the overall process of a vehicle charging method when the execution subject provided by the embodiment of the present application is a vehicle, wherein: In step 701: the power battery in the vehicle is controlled to discharge the on-board receiving end; so that the on-board receiving end generates a magnetic field based on the discharge operation; the magnetic field is used to cause the ground transmitting end to generate a wake-up signal, and the wake-up signal is used to wake up the wireless charging system.

[0077] The specific implementation of this step is the same as that of the above step 205 and will not be repeated here.

[0078] In step 702: establishing a communication connection with the wireless charging system.

[0079] The specific implementation of this step is the same as that of the above step 207 and will not be repeated here.

[0080] In step 703: a charging signal sent by the wireless charging system is received based on the communication connection.

[0081] The specific implementation of this step is the same as that of the above step 208 and will not be repeated here.

[0082] In step 704 : the charging relay is closed based on the charging signal.

[0083] The specific implementation of this step is the same as that of the above step 209 and will not be repeated here.

[0084] like Figure 8 FIG. 1 is a schematic diagram of the overall process of a vehicle charging method when the execution subject provided by the embodiment of the present application is a wireless charging system, wherein: In step 801: a wake-up signal is generated; the wake-up signal is generated based on a magnetic field, and the magnetic field is generated by an on-board receiving terminal in the vehicle based on a discharge operation.

[0085] The specific implementation of this step is the same as that of the above step 206 and will not be repeated here.

[0086] In step 802 : a communication connection is established with the vehicle based on the wake-up signal.

[0087] The specific implementation of this step is the same as that of the above step 207 and will not be repeated here.

[0088] In step 803: a charging signal is sent to the vehicle based on the communication connection, where the charging signal is used to instruct the vehicle to close the charging relay.

[0089] The specific implementation of this step is the same as that of the above step 208 and will not be repeated here.
