[0043] As mentioned above, the existing charging method for vehicle-mounted batteries has the problem of low charging safety. Specifically, when the high voltage of the whole vehicle is not powered on, the power battery does not charge the battery, and the whole vehicle is powered by the vehicle-mounted battery, which can easily cause the voltage of the vehicle-mounted battery to be low and trigger the vehicle to automatically charge. During the automatic charging process, the vehicle will not inform the user, and will directly power on the high voltage, close the power battery connection circuit, and the power battery will charge the battery. As a result, there is a risk of high-voltage electric shock when the user is using or repairing the vehicle, resulting in low charging safety.

[0044] In order to solve the above problems, an embodiment of the present application provides an intelligent charging method for a vehicle-mounted battery, including: first determining the current gear position of the vehicle. Then, when the current gear position is the ACC gear position or the OFF gear position, the voltage of the vehicle-mounted battery is detected by a remote terminal, and a first detection result is obtained. When the first detection result is less than or equal to the preset power-deficit threshold, a power replenishment prompt is sent to the user APP based on the cloud platform, requesting and waiting for the user's authorization feedback. Finally, when the authorization feedback is for agreeing to the authorization, the vehicle-mounted battery is charged through the power battery.

[0045] In this way, before the charging action is implemented and the whole vehicle is powered on with high voltage, the user's authorization is obtained through the user APP, and the user is fully informed that the whole vehicle is about to be powered on with high voltage, avoiding the risk of high-voltage electric shock when the user is using or repairing the vehicle, thereby improving charging safety.

[0046] It should be noted that the intelligent charging method, device, equipment and readable storage medium for a vehicle battery provided by the present application can be applied to the field of vehicle technology. The above is only an example and does not limit the application field of the intelligent charging method, device, equipment and readable storage medium for a vehicle battery provided by the present application.

[0047] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] Figure 1 A flow chart of a smart charging method for a vehicle-mounted battery provided in an embodiment of the present application. Figure 1 As shown, an intelligent charging method for a vehicle battery provided in an embodiment of the present application may include:

[0049] S101: Determine the current gear position of the vehicle.

[0050] In practical applications, the gears of a vehicle generally include ON, ACC and OFF gears. Different gears have different uses for the vehicle battery. For this reason, the embodiment of the present application sets a relatively independent intelligent charging solution for each different gear. The user operates the power gear of the vehicle, and the vehicle determines the power gear of the vehicle, that is, determines the current gear of the vehicle.

[0051] S102: When the current gear is the ACC gear or the OFF gear, the voltage of the vehicle battery is detected by using a remote terminal to obtain a first detection result.

[0052] In actual application, when the gear is in the ACC gear or OFF gear, in order to avoid the risk of high-voltage electric shock when the user is using or repairing the vehicle, the power battery generally does not automatically charge the vehicle battery. The vehicle is equipped with a remote terminal (TBOX) to detect the voltage of the vehicle battery and obtain the first detection result. It can be understood that since the loop voltage of the vehicle power supply KL30 is approximately equal to the battery voltage, and in order to save energy, the remote terminal can be used to periodically wake up the voltage monitoring module, cloud data interaction module and calculation and storage module in the internal module, without waking up the bus communication module (not waking up the vehicle network), and the loop voltage of the vehicle power supply KL30 is detected by the voltage monitoring module, and the result obtained by the detection (the first detection result) is used as the voltage of the vehicle battery. The vehicle battery is used to power the vehicle's low-voltage electrical appliances and electronic control system. It has a small capacity and a voltage of generally 12-24V. The first detection result is a specific voltage value between 0-24V, such as 0V, 5V, 10V, 12V, 13V, etc. The detection cycle may be 60 minutes, that is, the internal module of the remote terminal is awakened once every 60 minutes to perform a voltage detection on the vehicle battery.

[0053] In addition, since different gears correspond to different processing methods, the embodiment of the present application can illustrate a possible processing method.

[0054] In one embodiment, the method further comprises:

[0055] When the current gear is the ON gear, the vehicle controller is used to close the power battery connection circuit, and the vehicle-mounted battery is charged through the DC converter.

[0056] In actual application, when the vehicle's current gear is the ON gear, the vehicle starts, at which time the vehicle's high voltage is powered on, the power battery connection circuit is closed through the vehicle controller, and the vehicle's battery is charged through the DC converter (DCDC).

[0057] S103: When the first detection result is less than or equal to a preset power-deficit threshold, a power replenishment prompt is sent to the user APP based on the cloud platform, requesting and waiting for the user's authorization feedback.

[0058] In actual applications, the preset power feeding threshold is set by the vehicle factory or customized by the user later. It is generally 12V, but other reasonable values ​​can also be used to determine whether the vehicle battery has entered the pre-charging state. Specifically, when the preset power-loss threshold is 12V, if the detection signal (first detection result) has 10 consecutive values ​​and lasts for 5S, and the voltage value is ≤12V, the vehicle battery enters the pre-charging state, and a power replenishment prompt is sent to the user APP based on the cloud platform, requesting and waiting for the user to provide authorization feedback. Authorization feedback includes consent to authorization and disagreement to authorization, which is fed back to the cloud platform by the user through the user APP and triggers subsequent actions. As a possible power replenishment prompt, the power replenishment prompt may be "The battery is low, please start the vehicle in time."

[0059] In addition, since the methods of sending the power replenishment reminder are different, the embodiment of the present application can illustrate a possible sending method.

[0060] In one case, the S103: when the first detection result is less than or equal to a preset power-deficit threshold, sending a power replenishment prompt to the user APP based on the cloud platform, requesting and waiting for the user's authorization feedback, specifically includes:

[0061] When the first detection result is less than or equal to a preset power-deficit threshold, waking up the vehicle bus network, and using the vehicle bus network to send a battery power feed warning to the vehicle controller;

[0062] Using the remote terminal to collect all data about the vehicle on the vehicle bus and upload it to the cloud platform;

[0063] Based on the battery power feed warning and all the data, the cloud platform is used to send a power replenishment reminder to the user APP, requesting and waiting for the user's authorization feedback.

[0064] In actual application, when the gear is in the ACC gear, the user is generally in the driving position. Then, when the battery voltage is low (the first detection result is less than or equal to the preset power-loss threshold), the "low battery" warning light can be turned on in the instrument cluster, and the "low battery, please start the vehicle in time" can be displayed on the instrument LED screen. At the same time, the information is sent to the user APP through the cloud platform to inform the user of the "low battery, please start the vehicle in time" power replenishment reminder, and request and wait for the user's authorization feedback. When the gear is in the OFF gear, the user is generally not in the driving position. In order to save energy, when the battery voltage is low, it can not be fed back through the instrument cluster and the instrument LED screen, but only send a power replenishment reminder to the user APP through the cloud platform, and request and wait for the user's authorization feedback. Specifically, when the monitoring signal has 10 consecutive values ​​and lasts for 5s, and the voltage value is ≤12V, the remote terminal activates the bus communication module, and the bus communication module wakes up the vehicle bus network, and sends a battery power feed warning to the vehicle controller through the vehicle bus network. At this time, the remote terminal collects all data about the vehicle on the vehicle bus and uploads it to the cloud platform. The cloud platform sends a power boost to the user's APP, informing the user that "the battery is low, please start the vehicle in time" reminder.

[0065] In addition, when the monitoring signal has 10 consecutive values ​​for 5 seconds and the voltage value is greater than 12V, only the voltage information is reported to the cloud platform for recording and storage.

[0066] In addition, since the wake-up durations are not the same, the embodiment of the present application can illustrate a possible wake-up duration.

[0067] In one embodiment, the method further comprises:

[0068] Using the remote terminal to determine the wake-up duration of the vehicle bus network;

[0069] When the wake-up duration reaches a preset wake-up threshold, the vehicle bus network is controlled to sleep.

[0070] In practical applications, in order to save energy, the vehicle bus network cannot be kept awake all the time. To this end, the embodiment of the present application provides a preset wake-up threshold for determining whether the vehicle bus network has entered sleep mode. The preset wake-up threshold should not be too long, and is generally set to a reasonable value such as 1min or 2min. Taking the preset wake-up threshold of 1min as an example, the remote terminal determines the duration. When the wake-up duration of the vehicle bus network exceeds 1min, the remote terminal turns off the bus communication module, and the vehicle bus network enters sleep mode in turn after the bus wake-up event disappears.

[0071] S104: When the authorization feedback is authorization approval, the vehicle-mounted battery is charged via the power battery.

[0072] In actual applications, users’ authorization feedback varies. Figure 2 A charging flow chart of a vehicle-mounted battery provided in an embodiment of the present application. Figure 2 As shown in the figure, when the user operates the APP and feeds back the authorization feedback of "agree to authorization" to the cloud platform through the user APP, the remote terminal receives the command and issues a low-voltage power-on request to the vehicle controller. After the vehicle controller is powered on at low voltage, other controllers of the vehicle are powered on and awakened. At this time, the high-voltage power-on process is started, the hazard warning lights of the vehicle are turned on, and based on the battery management system, the power battery is used to charge the vehicle battery through the DC converter.

[0073] In addition, since different authorization feedbacks correspond to different charging methods, the embodiment of the present application can illustrate a possible authorization feedback and a corresponding charging method.

[0074] In one embodiment, the method further comprises:

[0075] When the authorization feedback is that the authorization is not approved, the remote terminal continues to periodically detect the voltage of the vehicle-mounted battery at a first preset frequency, and obtains a second detection result;

[0076] Storing the second detection result in the cloud platform;

[0077] Based on the second detection result, the cloud platform continues to send a charging reminder to the user APP at a second preset frequency, requesting and waiting for the user's authorization feedback.

[0078] In actual applications, when the user gives the cloud platform an authorization feedback of "disagree to authorization" through the user APP, the vehicle cannot actively carry out the charging process, and continues to use the remote terminal to periodically detect the voltage of the vehicle battery at the first preset frequency (the frequency of the above-mentioned remote terminal periodically waking up the internal module for voltage detection can be 60 minutes / time), and obtain the second detection result. The second detection result is the same as the first detection result, which is a specific voltage value between 0-24V, but the measurement time period is different, so the detection value obtained is generally different. The remote terminal sends the second detection result to the cloud platform for storage, and uses the cloud platform to send a charging reminder to the user APP at regular intervals (at the second preset frequency), requesting and waiting for the user's authorization feedback. The second preset frequency can be 24 hours / time, or other reasonable values.

[0079] In addition, since different authorization feedbacks correspond to different charging methods, the embodiment of the present application can illustrate a possible authorization feedback and a corresponding charging method.

[0080] In one embodiment, the method further comprises:

[0081] When the authorization feedback is not received within the preset feedback time, the vehicle-mounted battery is charged by the power battery.

[0082] In actual applications, although the cloud platform can send a charging reminder to the user's APP, the user may not reply to the authorization feedback to the cloud platform in time, that is, there may be no response. At this time, the vehicle cannot actively carry out the charging process, and continues to use the remote terminal to periodically detect the voltage of the on-board battery at the first preset frequency (30 minutes / time), and sends a charging reminder to the user APP at the second preset frequency (12 hours / time). When the preset feedback time is reached and no authorization feedback is received, it is judged that the user has not used the vehicle for a long time. The vehicle actively starts the battery charging process, the remote terminal receives the instruction, and issues a low-voltage power-on request to the vehicle controller. After the vehicle controller is powered on at low voltage, other controllers of the vehicle are powered on and awakened. At this time, the high-voltage power-on process is started, the vehicle's hazard warning lights are turned on, and the battery is charged through the power battery. Among them, the preset feedback time is set by the vehicle factory or user-defined, generally 7 days.

[0083] In addition, since the triggering conditions for stopping charging are not the same, the embodiment of the present application can illustrate one possible triggering condition.

[0084] In one embodiment, the method further comprises:

[0085] During the charging process of the vehicle-mounted battery, detecting whether a first stop condition is triggered; the first stop condition includes that the voltage of the power battery is lower than a preset voltage threshold, the charging time reaches a preset charging time, the current gear changes, and a request to exit charging sent by the user to the cloud platform through the user APP is received;

[0086] If any one of the first stop conditions is triggered, charging is stopped.

[0087] In actual applications, the charging action of the battery cannot be carried out all the time, so it is necessary to set the corresponding first stop condition, and stop the battery charging when the first stop condition is triggered. Specifically, the first stop condition includes the voltage of the power battery being lower than the preset voltage threshold, the charging time reaching the preset charging time, the current gear changing, and receiving the user's request to exit the power replenishment sent to the cloud platform through the user APP. It is understandable that when it is detected that the voltage of the power battery is lower than the preset voltage threshold, the charging time reaches the preset charging time (generally 20 minutes), the vehicle power gear changes, and the user requests to exit the power replenishment, the vehicle battery stops charging.

[0088] In summary, when the user operates the vehicle power gear, the vehicle power gear is determined. The gears include ON, ACC and OFF. When the power is in the ON gear, the controller wakes up, TBOX detects the battery status information and health status every 30 minutes and uploads it to the TSP cloud platform, and continuously monitors whether the power gear is in the ON gear. The BMS controls the power battery to continuously output power to the DCDC to supply power to the vehicle power load and the on-board battery. The VCU controls the vehicle in the READY state, and the vehicle controller monitors the battery health status. When the gear changes, the vehicle power gear continues to be determined. When the power gear is in ACC or OFF, TBOX sleeps, and the internal module is awakened by SMS wake-up every 60 minutes, without waking up the CAN transceiver module, and the vehicle power KL30 loop voltage is detected through the TBOX internal power monitoring circuit (this voltage can be considered to be approximately equal to the on-board battery voltage). The main positive and auxiliary relays of the power battery controlled by the BMS are not closed, and the DCDC has no power output. The VCU controls the vehicle controller to sleep (without waking up the vehicle network), thereby effectively reducing energy consumption. If the monitoring result shows that the battery voltage is continuously greater than 12V for 5s, the monitoring will continue; if it is continuously less than or equal to 12V for 5s, the CAN transceiver module inside the TBOX will be awakened, a wake-up message will be sent to the vehicle bus, and a charging reminder will be sent to the user APP through the cloud platform, notifying the user that the intelligent charging reminder is about to be entered. At this time, the BMS controls the CAN transceiver of the power battery to be awakened by the message, and the VCU controls the vehicle controller to be awakened by the vehicle network. If the user refuses to authorize, charging is prohibited. If the user authorizes and agrees or the user does not check the intelligent charging request within the time limit and it is detected that the vehicle has not been used for more than X days (X can be set by the user), the user authorization information will be sent to the vehicle controller through the vehicle bus, the vehicle status will be configured as the intelligent charging mode, the power battery main positive and negative relays will be controlled to be closed, the DCDC will be awakened, the intelligent charging process will be started, the main positive and negative relays will be closed, and the intelligent charging mode will be entered. At this time, the battery voltage is continuously monitored to see if it is continuously less than or equal to 12V for 5s and the user's authorization information. When the power battery voltage is lower than the threshold, the timer is greater than 20 minutes, the vehicle power gear changes, or the user requests to exit the charging, TBOX sends a request to exit the intelligent charging mode, and the BMS sends a high-voltage power-off request to disconnect the main positive and negative relays. The VCU receives the high-voltage power-off request, and the vehicle is successfully powered off, and each jumps to the working model according to the gear position, and the charging ends.

[0089] In summary, the present application first determines the current gear position of the vehicle. Then when the current gear position is the ACC gear position or the OFF gear position, the remote terminal is used to detect the voltage of the vehicle battery and obtain a first detection result. When the first detection result is less than or equal to the preset power-off threshold, a power replenishment prompt is sent to the user APP based on the cloud platform, requesting and waiting for the user's authorization feedback. Finally, when the authorization feedback is an authorization agreement, the vehicle battery is charged through the power battery. In this way, before the charging action is implemented and the whole vehicle is powered on at high voltage, the user authorization is obtained through the user APP, and the user is fully informed that the whole vehicle is about to be powered on at high voltage, thereby avoiding the risk of high-voltage electric shock when the user is using or repairing the vehicle, and improving the charging safety.
