[0038] In existing technical solutions, the main battery is usually used to provide power for the vehicle. However, when the main battery is used to supply power, the vehicle's key systems may not operate normally, causing the vehicle to be disabled and causing inconvenience to the user.

[0039] Based on the above problems, an embodiment of the present application proposes a vehicle battery control method, which is applied to a vehicle, wherein the vehicle includes a battery and an emergency power supply, and the battery and the emergency power supply are used to power the vehicle.

[0040] The vehicle battery control method provided in the embodiment of the present application is now described with reference to FIG1 .

[0041] FIG1 is a flow chart of an embodiment of a vehicle battery control method provided by the present application, which specifically includes the following steps:

[0042] Step S110: detecting the real-time voltage of the battery.

[0043] Specifically, an embodiment of the present application proposes that the control system of the vehicle may include a vehicle controller and an emergency control device, and the embodiments of the present application do not impose specific restrictions on this control system. The vehicle controller is a key part of the vehicle electronic control system of an electric vehicle. The vehicle controller can reasonably distribute energy, similar to the engine management system function in a traditional internal combustion engine vehicle, to maximize the efficiency of the energy utilization of the on-board battery. The electronic control unit of the vehicle controller is the core of the vehicle controller. The emergency control device consists of an independent controller and a power supply, which can control the vehicle independently of the vehicle controller and control the doors independently of the vehicle controller. The independent power supply can provide electronic control emergency support to the vehicle in a short period of time in the event of failure of the vehicle controller. When the independent controller is activated, it can use the internal battery as a backup power source for the system to temporarily provide power support for the vehicle.

[0044] For example, an embodiment of the present application takes the emergency control device controlling the vehicle as an example, and detects the voltage of the battery through the controller in the emergency control device to ensure the accuracy of the voltage data.

[0045] Furthermore, the controller in the emergency control device can also set a timer that triggers at regular intervals. When the timer triggers, the battery voltage is monitored in real time. The controller in the emergency control device can also read the positive and negative voltage values ​​of the battery through a voltage detection circuit or chip. If the real-time voltage value read by the controller in the emergency control device is an analog signal, the controller needs to use a digital-to-analog converter to convert it to a digital signal for subsequent processing.

[0046] Step S120: If the real-time voltage of the battery is less than the preset threshold voltage, the emergency power supply is started.

[0047] Specifically, one embodiment of the present application takes the emergency control device controlling the vehicle as an example, and the controller in the emergency control device can also compare the read voltage value with the preset threshold voltage. This threshold voltage is the lower limit of the battery starting voltage. If the real-time voltage detected by the controller in the emergency control device for multiple consecutive times is lower than the preset threshold voltage, the controller determines that the battery is in the feeding state and starts the emergency power supply. In order to avoid misjudgment, multiple detections or time delays can be set to confirm whether the battery is in the feeding state. The emergency power supply proposed in the present application may include a supercapacitor module, the charging and discharging process of which does not involve any changes in matter, and has the characteristics of short charging time, high charging efficiency, long service life, good temperature characteristics, energy saving and green environmental protection. The embodiments in the present application do not specifically limit the type of this supercapacitor.

[0048] Furthermore, an embodiment of the present application proposes that before starting the emergency power supply, the controller of the emergency control device first checks whether the emergency power supply is in an available state. The available state may include whether the power is sufficient, whether there is a fault, etc., and the embodiments of the present application do not impose specific restrictions on this. If the emergency power supply is in an available state, the controller sends a start signal to the emergency power supply, and the start signal may be a 3.3v digital signal. After receiving the start signal, the emergency power supply starts the startup process, activates the internal circuit, and starts the backup battery. After the emergency power supply is started, a confirmation signal is sent to the controller to inform the emergency control device that the emergency power supply has been successfully started and is ready to supply power. If the emergency power supply is in an abnormal state, feedback is given to the emergency control device that the emergency power supply is in an abnormal state.

[0049] Step S130: boosting the voltage of the battery and transmitting the boosted power of the battery to the emergency power supply.

[0050] Specifically, one embodiment of the present application takes the emergency control device controlling the vehicle as an example, and proposes to perform a boost operation on the battery. The embodiment of the present application proposes that the battery can be charged through a boost charging circuit, and the battery can also be charged through other methods. The embodiment of the present application does not specifically limit this boost operation. Taking charging the battery through a boost charging circuit as an example, the controller in the emergency control device activates the boost charging circuit. The boost charging circuit first increases the voltage of the main battery to a charging voltage suitable for the emergency power supply. Then, the boost charging circuit transfers the electrical energy of the main battery to the emergency power supply to achieve rapid charging. During this process, the controller in the emergency control device ensures the safety and efficiency of the charging process by monitoring the current and voltage. When the emergency power supply is charged to a sufficient voltage, the controller disconnects the boost charging circuit and prepares to start the emergency power supply.

[0051] Step S140: Switch the battery power supply to the emergency power supply.

[0052] Specifically, an embodiment of the present application takes the emergency control device controlling the vehicle as an example, and proposes that the emergency control device may also include a switching switch, which is used to cut off the connection between the main battery and the vehicle system when the main battery is feeding power, and connect the vehicle system to the emergency power supply to ensure the stability and reliability of the switching process.

[0053] Furthermore, before switching the battery power supply to the emergency power supply, first, the controller in the emergency control device will check the current voltage requirements of the vehicle's key systems, as well as the voltage and current output capabilities of the emergency power supply, to ensure that the vehicle can operate normally after the switch. Next, the controller in the emergency control device sends a signal to activate the switching switch, which may include a relay, a contactor, or a transistor switch, etc. The embodiments in this application do not impose specific restrictions on this. Then, the switching switch first disconnects the power supply connection of the main battery, and then quickly connects to the emergency power supply. Finally, after completing the switch, the switching switch will send a confirmation signal to the controller in the emergency control device to inform it that the vehicle power supply has been successfully switched from the main battery power supply to the emergency power supply.

[0054] Alternatively, another embodiment of the present application proposes that after switching from battery power to emergency power, the emergency power supply provides the vehicle with the required starting energy and rapidly discharges the energy to start the vehicle. During this process, the controller in the emergency control device monitors the current and voltage to ensure the safety and efficiency of the discharge process. When the vehicle is successfully started, the controller disconnects the emergency power supply, switches the emergency power supply to battery power via a toggle switch, restores power to the main battery, and shuts down the emergency power system for future use.

[0055] Optionally, another embodiment of the present invention takes the example of using an emergency control device to control a vehicle, and the vehicle can establish a communication connection with a mobile terminal through the emergency control device. The mobile terminal may include electronic devices such as mobile phones and tablets, and the embodiments of this application do not impose any special restrictions on this. The communication connection method may include Bluetooth or other communication connection methods, and the embodiments of this application do not impose any special restrictions on this. A graphical interface can be used on the mobile terminal to intuitively display the status of the battery and emergency power supply and the operating status of the vehicle. After receiving the battery feed signal, the user can remotely start the emergency power supply through the mobile terminal to achieve convenient human-computer interaction. The emergency control device can also remind the user of the current vehicle power status in multiple dimensions through the built-in buzzer in the controller and the push notification of the mobile terminal. The controller in the emergency control device can also include a fault diagnosis module, which can detect system faults in real time, and display and record fault information through the mobile terminal to facilitate the user's subsequent maintenance and management.

[0056] Optionally, another embodiment thereof takes the emergency control device controlling the vehicle as an example. When the vehicle is started, the controller in the emergency control device will automatically switch back to the main battery for power supply and turn off the emergency power supply for next use.

[0057] FIG2 is a schematic diagram of the structure of an embodiment of the device of the present application. As shown in FIG2 , the control device 200 of the vehicle battery may include:

[0058] A detection module 21, configured to detect the real-time voltage of the battery;

[0059] The starting module 22 is used to start the emergency power supply if the real-time voltage is less than a preset threshold voltage;

[0060] A boost module 23, the boost module 23 is used to boost the battery voltage;

[0061] a transmission module 24 for transmitting the boosted electrical energy of the battery to the emergency power supply;

[0062] The switching module 25 is used to switch the battery power supply to the emergency power supply.

[0063] In one possible implementation, the vehicle further includes a timer, and the detection module 21 is further configured to detect the real-time voltage of the battery in response to triggering of the timer.

[0064] In one possible implementation, the control device of the vehicle battery further includes a conversion module 26 , and the conversion module 26 is configured to convert the analog data of the real-time voltage into digital data.

[0065] In one possible implementation, the detection module 21 is further used to detect the real-time voltage of the battery multiple times within a preset time. If the multiple real-time voltages are all less than the preset threshold voltage, the battery is judged to be in a feeding state and the emergency power supply is started.

[0066] In one possible implementation, the detection module 21 is further used to detect the state of the emergency power supply to determine whether the emergency power supply can operate normally; if the emergency power supply is in a normal state, the emergency power supply is started; if the emergency power supply is in an abnormal state, feedback is given that the emergency power supply is in an abnormal state.
