[0002] Over-the-Air (OTA) upgrades for vehicles refer to the technology of remotely upgrading vehicle systems via wireless networks. This technology can cover multiple aspects, such as optimizing the human-machine interface, improving the performance of autonomous driving assistance systems, and improving the powertrain and battery.

[0003] The manufacturer packages the updated vehicle firmware and uploads it to a cloud server, establishing a connection with the vehicle via a cellular network. After the vehicle fully receives the necessary upgrade content uploaded to the cloud, the OTA management system distributes the received content to the ECU (Electronic Control Unit) control units responsible for each module, completes the update, and then sends feedback to the server.

[0004] However, in existing technologies, the battery power is insufficient for vehicle OTA upgrades, so the upgrade cannot be completed. Therefore, it is necessary to rely on the user to charge the vehicle battery while using the vehicle. Summary of the Invention

[0014] Optionally, if so, after determining whether there is a low-voltage upgrade requirement in the upgrade task information, the method further includes:

[0015] If not, when the vehicle is powered on, detect the vehicle's infotainment system upgrade requirements.

[0016] Upon receiving the upgrade request and detecting that the current battery charge meets the power requirements for the upgrade task information, the vehicle system is upgraded according to the upgrade task information.

[0017] Optionally, after the step of upgrading the vehicle system according to the upgrade task information upon receiving the upgrade request and detecting that the current battery charge meets the power requirements for the upgrade as stated in the upgrade task information, the method further includes:

[0018] When an upgrade request is received and it is detected that the current battery charge does not meet the charge required for the upgrade task information, the vehicle system guides the user to select an appointment time for the upgrade.

[0019] Before the scheduled upgrade time, the vehicle's infotainment system will guide the user to power off the electric vehicle.

[0020] When the electric vehicle is powered off, return to the step of adjusting the charging threshold of the electric vehicle battery based on the upgrade task information.

[0021] Optionally, after the step of charging the battery by triggering the high-voltage circuit of the electric vehicle when the current charge of the battery is lower than the adjusted charging threshold, the method further includes:

[0022] When the battery is fully charged and the electric vehicle is powered on, the vehicle's infotainment system upgrade requirement is detected.

[0023] Upon receiving the upgrade request and detecting that the current battery charge meets the power requirements for the upgrade task information, the vehicle system is upgraded according to the upgrade task information.

[0024] Optionally, after the step of charging the battery by triggering the high-voltage circuit of the electric vehicle when the current charge of the battery is lower than the adjusted charging threshold, the method further includes:

[0025] When the vehicle system upgrade is completed or the battery charging fails, the adjusted charging threshold will be restored to the original charging threshold.

[0026] Furthermore, to achieve the above objectives, this application also proposes an intelligent power replenishment device, the device comprising:

[0027] The acquisition module is used to acquire upgrade task information for electric vehicles;

[0028] The adjustment module is used to determine the charging threshold of the electric vehicle battery based on the upgrade task information;

[0032] In addition, to achieve the above objectives, this application also proposes an electric vehicle that can implement the steps of the intelligent charging method described in any of the above claims.

The user is unaware of the charging process during the powered-off state, and the upgrade is performed after the charging is completed, improving the success rate and upgrade experience of the user's first upgrade.

[0042]

[0043] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0044] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of this application and are not intended to limit this application.

[0045] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0046] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0047] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0048] The main solution of this application embodiment is: when the vehicle is in a power-off state, if the current battery charge is detected to be lower than the adjusted charging threshold, the high-voltage circuit of the electric vehicle is triggered to charge the battery, and the vehicle is upgraded via OTA when the battery charging is completed and the vehicle is in a power-on state.

[0049] In this embodiment, for ease of description, the vehicle OTA management system will be used as the execution subject in the following description.

[0050] This application provides a solution: a smart charging method for electric vehicles (EVs) in a powered-off state. The smart charging method includes: acquiring upgrade task information of the EV; determining a charging threshold for the EV battery based on the upgrade task information; and charging the battery by triggering the EV's high-voltage circuit when the battery's current charge level is lower than the adjusted charging threshold. Compared to existing technologies where on-board OTA upgrades rely on user-initiated battery charging during vehicle use, this application identifies battery power consumption when an upgrade task is available and triggers an increase in the smart charging threshold to pre-charge the battery to meet upgrade requirements. Charging occurs imperceptibly to the user during the powered-off process, and the upgrade is performed only after charging is complete, improving the success rate and overall upgrade experience.

[0051] Based on this, the embodiments of this application provide an intelligent power replenishment method.

[0052] refer to Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the intelligent power replenishment method proposed in this application.

[0053] Considering that current in-vehicle OTA upgrades rely on the user charging the vehicle battery while the vehicle is powered on, this technology aims to recharge the battery when the vehicle is powered off, and then perform the upgrade after recharging, thereby improving the success rate and user experience of the upgrade. Figure 1 As shown, the intelligent power replenishment method described in this embodiment includes steps S10 to S3:

[0054] Step S10: Obtain upgrade task information for electric vehicles.

[0055] It should be noted that the upgrade task information is an OTA upgrade task. When there is an OTA upgrade task, the upgrade task will be downloaded. The OTA upgrade task includes: upgrading the ECU (Electronic Control Unit), the upgrade package, the power status required for the upgrade, and the power threshold if there is a low-voltage upgrade requirement.

[0056] Step S20: Determine the charging threshold of the electric vehicle battery based on the upgrade task information.

[0057] It should be noted that the downloaded task information is analyzed to see if there is a need for low-voltage upgrades. If there is a need for low-voltage upgrades, the ECU that needs to be upgraded and the corresponding upgrade package data are obtained from the OTA upgrade task. The minimum battery power required for the upgrade task is obtained, and the adjustment and charging threshold is issued through the OTA remote server platform.

[0058] Understandably, the battery charging threshold refers to the minimum state of charge (SOC) value at which the battery needs to begin charging, and it is set according to low-voltage upgrade requirements. Low-voltage upgrade requirements refer to over-the-air (OTA) upgrades of the vehicle's low-voltage module. Electric vehicles typically use 12V or 24V (with a growing trend towards 48V) power supply for their low-voltage modules. These modules primarily provide power to conventional equipment in the cabin, such as lighting, entertainment systems, and windshield wipers, as well as to the vehicle control center (e.g., vehicle controller, battery management system, motor controller). With the continuous development of automotive electrification and intelligence, low-voltage modules need to support more electronic devices and functions, such as intelligent driving systems and high-resolution entertainment systems. These new functions and devices often require higher power supplies; therefore, upgrading the low-voltage module may require increasing the power supply capacity, i.e., adjusting the electric vehicle battery charging threshold.

[0059] Step S30: When the current charge of the battery is lower than the adjusted charging threshold, the battery is charged by triggering the high-voltage circuit of the electric vehicle.

[0060] It should be noted that the vehicle is powered off when the battery is being charged. After the vehicle is powered off, the difference between the current battery level and the current charging threshold is periodically checked. If the current battery level is lower than the current charging threshold, the vehicle triggers high-voltage operation to charge the battery. If the current battery level is not lower than the current charging threshold, charging the battery stops.

[0061] It is understood that the cycle time can be set according to actual conditions, and this embodiment does not impose any restrictions. The vehicle power-on state refers to the vehicle's power system being powered on and in a ready-to-operate state. In this state, the vehicle's various electrical devices and systems begin to start and prepare for operation. Specifically, the vehicle power-on state includes the following characteristics: power connection: the vehicle's battery or other power system is connected, providing the vehicle with the necessary electrical energy; electrical device startup: with the power connection, the vehicle's various electrical devices (such as the dashboard, lights, audio system, etc.) begin to start and are in standby or operating state; system self-check: after the vehicle is powered on, each system of the vehicle will perform a self-check to ensure its normal operation. For example, the battery management system (BMS) will check parameters such as battery voltage, current, and temperature to ensure the battery is in a safe state; ready to run: the vehicle power-on state is a prerequisite for the vehicle to be ready to run. Only when the vehicle is powered on can the driver start the engine or electric motor to put the vehicle into driving mode. The vehicle power-off state refers to the state where the vehicle's power system has been de-energized, and the vehicle's various electrical devices and systems have stopped operating. Specifically, the vehicle's power-off state includes the following characteristics: power disconnection, the vehicle's battery or other power systems have been disconnected and no longer provide power to the vehicle; electrical equipment shutdown, with the power disconnection, the vehicle's various electrical equipment (such as the dashboard, lights, audio, etc.) stop operating and shut down; system hibernation, after the vehicle is powered off, the vehicle's various systems will enter a hibernation state to reduce battery power consumption and extend battery life; safety protection, the vehicle power-off state is a vehicle safety protection measure, when the vehicle is parked for a long time or not needed, putting the vehicle in the power-off state can prevent the battery from over-discharging and being damaged.

[0062] In the specific implementation, the upgrade task information of the electric vehicle is obtained, and the charging threshold of the electric vehicle battery is determined according to the upgrade task information. When the current charge of the battery is lower than the adjusted charging threshold, the high voltage circuit of the electric vehicle is triggered to charge the battery. After the battery is charged, the vehicle is upgraded via OTA, thereby improving the success rate of the user's upgrade and the upgrade experience.

[0063] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to the first embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 2 , Figure 2 This is a flowchart illustrating the second embodiment of the intelligent power replenishment method proposed in this application.

[0064] Considering that there are low-voltage upgrade requirements in the vehicle OTA upgrade task, and in order to meet the power requirements of the low-voltage module upgrade, step S20 in this embodiment specifically includes:

[0065] Step S21: Based on the upgrade task information, determine whether there is a low-voltage upgrade requirement in the upgrade task information.

[0066] Step S22: If so, determine the battery charging threshold based on the low-voltage upgrade.

[0067] It should be noted that the low-voltage upgrade requirement includes a low-voltage upgrade threshold, and the intelligent power replenishment threshold is adjusted based on the low-voltage upgrade threshold.

[0068] In practice, the vehicle downloads OTA upgrade task information while driving. After the download is complete, the downloaded upgrade task information is analyzed to see if there is a need for low-voltage upgrade. If there is a need for low-voltage upgrade, the ECU that needs to be upgraded and the corresponding upgrade package data are obtained from the vehicle OTA upgrade task. The minimum battery power required for the upgrade task is obtained, and the power replenishment threshold is adjusted through the OTA remote server platform to meet the power requirements of the low-voltage module upgrade.

[0069] Furthermore, after step S22 in this embodiment, the method further includes:

[0070] If not, when the vehicle is powered on, detect the vehicle's infotainment system upgrade requirements.

[0071] Upon receiving the upgrade request and detecting that the current battery charge meets the power requirements for the upgrade task information, the vehicle system is upgraded according to the upgrade task information.

[0072] It should be noted that after the user manually powers on the vehicle, a pop-up window will prompt the user to upgrade. After powering on the vehicle, the user can click "Upgrade Now" or schedule an upgrade. When the scheduled time arrives and the vehicle is powered on, the vehicle will enter the pre-upgrade condition detection phase. At this time, the battery power will be checked to see if it meets the power requirements for the upgrade task information. If the battery power meets the requirements, the vehicle will enter the upgrade phase and perform an OTA upgrade.

[0073] In practice, if there is no low-voltage upgrade requirement in the upgrade task information, the vehicle system upgrade requirement of the electric vehicle is detected when the vehicle is powered on. When the upgrade requirement is received and the current battery charge is detected to meet the power requirement for the upgrade in the upgrade task information, the vehicle system is upgraded according to the upgrade task information, thereby improving the success rate of the user's upgrade and the upgrade experience.

[0074] Furthermore, in this embodiment, after receiving the upgrade request and detecting that the current battery charge meets the power requirement for the upgrade in the upgrade task information, the step of upgrading the vehicle system according to the upgrade task information further includes:

[0075] When an upgrade request is received and it is detected that the current battery charge does not meet the charge required for the upgrade task information, the vehicle system guides the user to select an appointment time for the upgrade.

[0076] Before the scheduled upgrade time, the vehicle's infotainment system will guide the user to power off the electric vehicle.

[0077] When the electric vehicle is powered off, return to the step of adjusting the charging threshold of the electric vehicle battery based on the upgrade task information.

[0078] It should be noted that the scheduled upgrade time can be set according to the actual situation, and this embodiment does not impose any restrictions.

[0079] In specific implementation, when an upgrade request is received and it is detected that the current battery charge does not meet the power requirements for the upgrade task information, the vehicle system guides the user to select an appointment time for the upgrade. Before the appointment time, the vehicle system guides the user to power off the electric vehicle. While the electric vehicle is powered off, the system returns to the step of adjusting the battery charging threshold according to the upgrade task information. When the current battery charge is lower than the adjusted charging threshold, the high-voltage circuit of the electric vehicle is triggered to charge the battery, thereby charging the battery to prepare for the vehicle OTA upgrade.

[0080] Based on the second embodiment of this application, in the third embodiment of this application, the content that is the same as or similar to the second embodiment described above can be referred to the above description, and will not be repeated hereafter. Based on this, please refer to... Figure 3 , Figure 3 This is a flowchart illustrating the third embodiment of the intelligent power replenishment method proposed in this application.

[0081] Considering that an OTA upgrade will be performed on the vehicle after the battery is recharged, this embodiment further includes the following after step S30:

[0082] Step S301: When the battery is fully charged and the electric vehicle is powered on, detect the vehicle system upgrade requirements of the electric vehicle.

[0083] Step S302: Upon receiving the upgrade request and detecting that the current battery charge meets the power requirement for the upgrade in the upgrade task information, upgrade the vehicle system according to the upgrade task information.

[0084] It should be noted that receiving the upgrade request means that after the user manually powers on the vehicle, a pop-up window prompts the user to upgrade, and the user clicks "Upgrade Now" after powering on the vehicle, or the user schedules an upgrade appointment, arrives at the scheduled time, and the vehicle is powered on.

[0085] In a specific implementation, when the battery is fully charged and the electric vehicle is powered on, the vehicle system upgrade requirement of the electric vehicle is detected; when the upgrade requirement is received and it is detected that the current battery charge meets the power requirement for the upgrade in the upgrade task information, the vehicle system is upgraded according to the upgrade task information, thereby enabling the vehicle to be recharged without the user's awareness, and the upgrade is performed after the recharge is completed.

[0086] Furthermore, considering that after the vehicle OTA upgrade is completed, in order to prevent continuous charging from consuming a large amount of battery power, this embodiment also includes the following after step S30:

[0087] Step S303: When the vehicle system upgrade is completed or the battery charging fails, restore the adjusted charging threshold to the original charging threshold.

[0088] It should be noted that after the upgrade is complete, the OTAmaster program will trigger the restoration of the default charging threshold. The default charging threshold will also be restored if the vehicle has not undergone an OTA upgrade for an extended period. The adjusted and unadjusted charging thresholds can be set according to actual conditions; this embodiment does not impose any restrictions.

[0089] Understandably, the OTA Master program is a core component in the vehicle OTA upgrade process. It is responsible for managing and coordinating the entire upgrade process. This program usually runs on the vehicle's onboard communication module (such as T-BOX) and communicates with the vehicle's ECU (Electronic Control Unit) to enable remote software updates.

[0090] In practice, when the vehicle system upgrade is completed or the battery charging fails, the adjusted charging threshold will be restored to the original charging threshold to prevent the battery from continuously charging and consuming a large amount of battery power.

[0091] It should be noted that, as Figure 5 As shown, Figure 5This is the overall framework diagram of the intelligent charging solution applicable to OTA in this application. First, the OTA server sends an upgrade task, the vehicle downloads the upgrade package, and after the download is complete, it analyzes whether the upgrade task has a low-voltage upgrade requirement. If there is a low-voltage upgrade requirement, it analyzes the low-voltage upgrade threshold requirement in the task information and adjusts the (intelligent) charging threshold. During the vehicle's power-off state, it periodically detects the current battery level and checks whether the current level is lower than the currently set intelligent charging threshold. If the current level is lower than the currently set intelligent charging threshold, the high-voltage operation is triggered to charge the battery during the vehicle's power-off state. If the current level is higher than the currently set intelligent charging threshold, charging the battery stops. If there is no need for a low-voltage upgrade, a pop-up window will appear after the vehicle is powered off and then powered on again, prompting the user that there is an upgrade available. The user clicks "Upgrade Now" or "Schedule an Upgrade," and when the scheduled time arrives and the vehicle is powered on, the system checks if the battery level meets the upgrade requirements specified in the upgrade task information. If the battery level meets the requirements, the vehicle enters the upgrade phase. If the battery level does not meet the requirements, the user is guided through the vehicle's infotainment system (HMI) to schedule an upgrade. The user selects a time to schedule the upgrade, and the vehicle completes the power replenishment while powered off. After the upgrade is complete, if battery charging fails, or if the vehicle has not undergone an OTA upgrade for an extended period, the power replenishment threshold reverts to the default threshold.

[0092] In addition, to achieve the above objectives, such as Figure 4 As shown, this application also proposes an intelligent power replenishment device, the device comprising:

[0093] Module 10 is used to acquire upgrade task information for electric vehicles;

[0094] Adjustment module 20 is used to determine the charging threshold of the electric vehicle battery based on the upgrade task information;

[0095] The charging module 30 is used to charge the battery by triggering the high-voltage circuit of the electric vehicle when the current charge of the battery is lower than the adjusted charging threshold.

[0096] In addition, to achieve the above objectives, this application also proposes an intelligent power replenishment device, the device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, the computer program being configured to implement the steps of the intelligent power replenishment method.

[0097] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the intelligent power replenishment method.

[0098] In addition, to achieve the above objectives, this application also proposes an electric vehicle that can implement the steps of the intelligent charging method described in any of the above claims.

[0099] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
