[0040] Embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Embodiments of the present invention are described in detail below.

[0041] Reference below Figure 1-Figure 3 A vehicle and a charging control method, device, electronic device, and readable storage medium thereof according to embodiments of the present invention are described.

[0042] Figure 1 FIG. 1 is a flow chart of a vehicle charging control method according to an embodiment of the present invention. Figure 1 As shown, the vehicle charging control method includes:

[0043] Step S1: When the vehicle is AC charging, charging information is obtained.

[0044] Specifically, when the user inserts the AC charging gun into the AC charging port of the vehicle, the vehicle starts AC charging, that is, the charging cabinet is connected to the vehicle's on-board charger, and current is sent to the vehicle to charge the vehicle's battery pack. During the charging process, the charging data and charging status and other information can be obtained in real time through the vehicle's built-in sensors, controllers, communication interfaces and other hardware devices.

[0045] Step S2: If it is determined based on the charging information that the battery management system's monitoring function on the battery pack fails, a preset protection action is executed to prevent the battery pack from being overcharged.

[0046] Specifically, after obtaining the charging information, it is possible to determine whether the battery management system's monitoring function for the battery pack has failed based on the charging information, that is, by performing real-time analysis and evaluation on various charging data collected by the vehicle during the AC charging process to determine whether the battery management system can normally monitor the status of the battery pack and whether the protection function of the battery pack has failed. When it is determined that the battery management system's monitoring function for the battery pack has failed, the preset protection action can be executed to prevent the battery pack from overcharging during the AC charging process in an all-round and multi-level manner. The preset protection action can be pre-set based on test data or actual conditions, including but not limited to cutting off the charging current, stopping power supply to the battery pack, etc., to ensure that when the battery management system's monitoring function fails, the vehicle can respond quickly and accurately to protect the battery pack from damage from overcharging.

[0047] In summary, according to the vehicle charging control method of an embodiment of the present invention, during the charging process of the vehicle, the charging information can be obtained to determine the monitoring status of the battery pack by the battery management system, so that when the monitoring function of the battery pack by the battery management system fails, corresponding measures can be taken to solve the problem of battery pack overcharging, effectively reducing the possibility of battery damage and vehicle failure, protecting users from economic losses, thereby improving the safety of the vehicle and the user's car experience.

[0048] In one embodiment of the present invention, the charging information includes: information related to at least one of a battery pack, an on-board charger, and a battery management system.

[0049] Specifically, the charging information includes information related to at least one of the battery pack, the on-board charger and the battery management system. Among them, the battery pack, as the energy storage unit of the vehicle, can affect the performance and cruising range of the vehicle. The information related to the battery pack includes but is not limited to the charge state of the battery pack, as well as the voltage, current and other parameters of the battery pack, so as to monitor the working state of the battery pack; the on-board charger, as the charging device of the battery pack, can convert the AC power of the AC charging cabinet into DC power to charge the battery pack. The information related to the on-board charger includes but is not limited to the charging voltage and charging current of the on-board charger, so as to monitor the charging safety and stability during the charging process; the battery management system, as a monitoring system for the battery pack, can monitor and manage various parameters of the battery pack, and perform detection and send relevant information. The information related to the battery management system includes but is not limited to battery monitoring data, so as to monitor abnormal conditions during the charging process.

[0050] In one embodiment of the present invention, the charging information includes the input voltage of the battery pack; the situation in which the battery management system's monitoring function for the battery pack fails includes that the input voltage of the battery pack is greater than or equal to a preset battery pack safety voltage threshold.

[0051] Specifically, the charging information includes the input voltage of the battery pack, that is, the DC voltage provided by the on-board charger to the battery pack. During the charging process of the vehicle, the input voltage of the battery pack can be continuously monitored and compared with the preset battery pack safety voltage threshold. When it is detected that the input voltage of the battery pack continues to rise and reaches or exceeds the preset battery pack safety voltage threshold, it indicates that the battery pack is receiving an excessively high charging voltage, and it can be determined that the battery management system's monitoring function of the battery pack has failed.

[0052] In a specific embodiment, the preset battery pack safety voltage threshold may be determined based on the technical specifications, experimental data or industry standards of the battery pack of the vehicle, and is used to indicate the maximum voltage value that the battery pack can safely withstand.

[0053] In one embodiment of the present invention, the charging information includes the highest voltage among the voltages of each single cell in the battery pack; the situation in which the battery management system fails to monitor the battery pack includes that the highest voltage among the voltages of each single cell in the battery pack is greater than a preset single cell safety voltage threshold.

[0054] Specifically, the charging information includes the highest voltage among the voltages of each single cell in the battery pack, that is, the voltage of the single cell with the largest voltage value among all the single cells in the battery pack. During the charging process of the vehicle, the highest voltage value among the voltages of each single cell in the battery pack can be continuously monitored and compared with the preset single cell safety voltage threshold. When the highest voltage among the voltages of each single cell in the battery pack is greater than the preset single cell safety voltage threshold, it indicates that at least one single cell in the battery pack is receiving an excessively high charging voltage, and it can be determined that the battery management system's monitoring function for the battery pack has failed.

[0055] In a specific embodiment, the preset single cell safety voltage threshold can be determined based on the technical specifications, experimental data or industry standards of the single cells in the battery pack of the vehicle, and is used to indicate the maximum voltage value that the single cells in the battery pack can safely withstand.

[0056] In one embodiment of the present invention, the charging information includes the output voltage of the on-board charger; the situation in which the battery management system's monitoring function for the battery pack fails includes the output voltage of the on-board charger being greater than a preset on-board charger safety voltage threshold.

[0057] Specifically, the charging information includes the output voltage of the on-board charger, that is, the DC voltage provided by the on-board charger to the battery pack. During the charging process of the vehicle, the DC voltage provided by the on-board charger to the battery pack can be continuously monitored and compared with the preset on-board charger safety voltage threshold. When the output voltage of the on-board charger continues to rise and exceeds the preset on-board charger safety voltage threshold, it indicates that the output voltage of the on-board charger will damage the on-board charger and cause the battery pack to receive an excessively high charging voltage. It can be determined that the battery management system's monitoring function of the battery pack has failed.

[0058] In a specific embodiment, the preset on-board charger safety voltage threshold can be determined based on the design specifications of the on-board charger, the technical specifications of the vehicle's battery pack, experimental data or industry standards, and is used to indicate the highest safety voltage that will not damage the on-board charger.

[0059] In one embodiment of the present invention, the charging information includes the operating status of the battery management system; and the situation in which the monitoring function of the battery management system on the battery pack fails includes an abnormality in the operating status of the battery management system.

[0060] Specifically, the charging information includes the operating status of the battery management system, that is, during the charging process, the battery management system monitors the entire charging process, including but not limited to monitoring the various parameters of the battery pack, such as voltage, current, temperature, and whether the battery pack is fully charged. During the charging process of the vehicle, the operating status of the battery management system can be continuously monitored for abnormalities. When it is determined that the operating status of the battery management system is abnormal, it indicates that the battery management system cannot accurately obtain the status information of the battery pack, or cannot effectively control the charging process of the battery pack. It can be determined that the battery management system's monitoring function of the battery pack has failed.

[0061] In one embodiment of the present invention, the abnormality in the running state of the battery management system includes an abnormality in the life frame sent by the battery management system.

[0062] Specifically, in the process of detecting whether the operating status of the battery management system is abnormal, it is possible to judge whether its operating status is normal by monitoring the life frames in the message sent by the battery management system when the battery management system communicates with the on-board charger. When the life frames sent by the battery management system are abnormal, including but not limited to unstable sending frequency, incomplete content or incorrect format of the sent life frames, it can be determined that the operating status of the battery management system is abnormal.

[0063] In one embodiment of the present invention, the preset protection action includes at least one of the following: stopping charging of the vehicle; sending a preset prompt message to the user terminal; sending a preset prompt message to the vehicle terminal.

[0064] Specifically, when it is determined that the battery management system's monitoring function for the battery pack has failed, a preset protection action can be executed, wherein the preset protection action includes at least one of the following: stopping charging the vehicle, that is, when it is detected that the battery management system's monitoring function has failed, the charging power supply can be cut off, and the charging process of the vehicle can be stopped to prevent overcharging from causing damage to the battery pack and the vehicle; sending a preset prompt message to the user terminal, that is, when it is detected that the battery management system's monitoring function has failed, the preset prompt message is sent to the user by text message or other means through the user terminal connected to the vehicle (such as the vehicle APP on a smart phone, a portable device such as a smart watch), so as to ensure that the user is informed of the abnormal situation at the first time and to facilitate timely intervention; sending a preset prompt message to the vehicle terminal, that is, when it is detected that the battery management system's monitoring function has failed, the preset prompt message can be sent to the vehicle terminal (the vehicle's dashboard, central control screen or other display device) to display intuitive prompt information to the user, so as to facilitate the user to perform corresponding operations according to the prompt information.

[0065] In one embodiment of the present invention, stopping charging the vehicle includes: controlling the on-board charger to disconnect the power supply connection with the external power supply to stop charging the vehicle.

[0066] Specifically, when it is determined that the battery management system's monitoring function for the battery pack has failed, it can trigger an instruction to stop charging the vehicle and control the on-board charger to disconnect from the external power supply (such as a charging pile or a household power socket), thereby stopping the charging process of the vehicle and ensuring that current no longer flows into the battery pack to prevent the battery pack from overcharging during the charging process.

[0067] In one embodiment of the present invention, controlling the power connection between the on-board charger and the external power supply includes: controlling a switch in the on-board charger connected to the external power supply to turn off, so as to disconnect the power connection between the on-board charger and the external power supply.

[0068] Specifically, in the process of controlling the power connection between the on-board charger and the external power supply, the switch in the on-board charger connected to the external power supply can be controlled to be turned off, including but not limited to controlling the shutdown of electronic devices such as contactors and relays. Specifically, after receiving the shutdown command, the on-board charger can control the switch device to perform the shutdown operation, disconnect the power connection between the on-board charger and the external power supply, so that the power transmission path between the on-board charger and the external power supply is isolated, and the on-board charger can no longer obtain power from the external power supply for charging, thereby stopping charging and preventing the battery pack from overcharging.

[0069] In one embodiment of the present invention, the preset prompt information is sent in at least one of the following ways: sound, text, and image.

[0070] Specifically, the preset prompt information is sent in at least one of the following ways: sound, text, and image, wherein the sound prompt information includes but is not limited to specific warning sounds, voice synthesis broadcasts, etc. played through audio devices such as speakers and buzzers in the car, and the sound frequency can be gradually changed from slow to fast to remind the user; the text prompt information includes but is not limited to the content presented in text form on the vehicle's dashboard, central control touch screen, head-up display and other vehicle-mounted display screens, and the content can be "Battery management system failure, please check" or "Battery management system monitoring function for battery pack fails, please stop charging immediately"; the image prompt information includes but is not limited to standardized fault warning icons, such as battery icons, exclamation marks, red backgrounds, etc., to intuitively display the fault status. It is understandable that sound, text and images can be combined to form multi-sensory stimulation and improve the warning effect, such as playing warning sounds, displaying fault icons and providing text descriptions at the same time.
