The signal processing module is further configured to prevent the power module from outputting a voltage signal to the signal processing module when the power module has an operating voltage.

[0007] In the above scheme, the signal processing module further includes: a second diode, wherein: The input terminal of the second diode is connected to the second terminal of the charging interface, and the output terminal of the second diode is connected to the first terminal of the voltage processor.

Therefore, "embodiments of this application" or "in the foreign embodiments" appearing throughout the specification do not necessarily refer to the same embodiment.

In the various embodiments of this application, the sequence numbers of the above-described processes do not imply a sequential order of execution; the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application. The sequence numbers of the above-described embodiments are merely descriptive and do not represent the superiority or inferiority of the embodiments.

[0018] Unless otherwise specified, any step in the embodiments of this application performed by the electronic device may be executed by the processor of the electronic device. It is also worth noting that the embodiments of this application do not limit the order in which the electronic device performs the following steps. Furthermore, the methods used to process data in different embodiments may be the same or different methods. It should also be noted that any step in the embodiments of this application can be executed independently by the electronic device; that is, when the electronic device performs any step in the following embodiments, it may not depend on the execution of other steps.

[0019] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

[0020] This application provides a power supply device, referring to... Figure 1 As shown, the power supply device 1 includes: The charging module 11 is connected to an external power source and is used to output the first voltage. The signal processing module 12 is connected to the charging module 11 and is used to process the first voltage output by the charging module to obtain a second voltage, and then output it to the power supply module. Power module 13, connected to signal processing module 12, is used to receive a second voltage output by signal processing module and output the second voltage to target component of the driving device when the power module cannot provide operating voltage, so as to charge the driving device through the target component; the second voltage is less than the operating voltage. The signal processing module 12 is also used to prevent the power module from outputting a voltage signal to the signal processing module when the power module has an operating voltage.

[0021] Specifically, a charging module can refer to a module in an electric vehicle that enables normal on-board charging. It should be noted that when the power module of the driving device can provide normal operating voltage, the charging module can supply power and charge the connected device; the driving device can refer to a two-wheeled electric vehicle. Of course, the charging module has bidirectional power supply capability and can also input the voltage of an external power source connected to it into the power supply device. In one feasible embodiment, the charging module can refer to a module that enables normal on-board fast charging and can supply power bidirectionally; the external power source can refer to an external portable power supply device, such as a power bank or portable energy storage device. Furthermore, this external power source has a certain battery capacity and output capability, and can be used as a temporary power source when the electric vehicle's power module (i.e., the power battery) cannot provide power.

[0022] In other embodiments of this application, the signal processing module may refer to a module capable of processing voltage signals. Specifically, the signal processing module can perform voltage reduction, voltage regulation, voltage boosting, and filtering on the first voltage output from the charging module to obtain a second voltage. It should be noted that the set value of the second voltage is lower than the operating voltage of the power supply module to meet the power requirements of the vehicle's low-voltage system and avoid damage to electronic components due to excessive voltage. In addition, the signal processing module also has a reverse current prevention function, that is, when the power supply module itself has voltage, it can actively prevent the power supply module from supplying reverse power to the signal processing module to prevent current backflow from causing short circuits or component burnout, so as to ensure that the signal processing module can normally output the second voltage to the power supply module.

[0023] In other embodiments of this application, the power module is responsible for supplying power to the vehicle's low-voltage system within the driving equipment. Under normal operating conditions, the power module receives its operating voltage (e.g., 12V or 24V) from the power battery or on-board charger. When the power battery is depleted or disconnected, the power module loses its main power supply and cannot continue to provide operating voltage, entering an emergency mode where the power module cannot provide operating voltage. In this emergency mode, the power module can obtain a second voltage from the signal processing module and directly supply this second voltage to the target component. It should be noted that the target component refers to a mechanical or electronic device within the driving equipment that requires electrical drive to perform the unlocking action.

[0024] In one feasible embodiment, the target component may include various locks, door locks, battery compartment locks, tailgate locks, etc. Upon receiving the second voltage, the target component activates an internal motor or electromagnet to perform an unlocking action, allowing the user to open a specific area of ​​the electric vehicle, insert the power battery, or remove the charger, thereby restoring the electric vehicle to normal operation.

[0025] It should be noted that the second voltage is lower than the operating voltage of the power module, but it is still sufficient to drive the target component into operating mode. In one feasible embodiment, the second voltage can be 7-8V; the operating voltage is 9-16V.

[0026] In other embodiments of this application, when the power module restores its operating voltage (such as when the power battery is reconnected or the vehicle charger is supplying power normally), the signal processing module stops drawing power from the external power source and prevents the power module from supplying power to the signal processing module in reverse. This can avoid power conflicts when two power sources coexist, prevent reverse current flow of normal voltage, and protect the signal processing module.

[0027] Based on the foregoing embodiments, in other embodiments of this application, refer to... Figure 2 As shown, the charging module 11 includes: a charging interface 111 and a charging controller 112, wherein: The first end of the charging interface 111 is connected to one end of the charging controller 112, and the second end of the charging interface 111 is connected to an external power source. The other end of the charging controller 112 is connected to the signal processing module 12.

[0028] The charging interface is a physical connection device used to realize the transfer of electrical energy between an external power source and the internal circuit system of an electric vehicle. The charging interface has bidirectional power supply capability, supporting both normal charging mode and emergency reverse power supply mode. In one feasible embodiment, the charging interface may include a Type-C interface, a Micro-USB interface, a USB-A interface, etc. In this application, a Type-C interface is preferred, and the Type-C interface supports multiple fast charging protocols; the Type-C interface has a higher transmission rate and stronger compatibility.

[0029] Specifically, the internal circuit structure of the charging controller may include a Type-C fast charging protocol circuit capable of enabling fast charging. This circuit, together with the Type-C interface, supplies power or charges devices connected to the Type-C interface when the power module can provide operating voltage. Conversely, when the power module cannot provide operating voltage, the Type-C fast charging protocol circuit, together with the Type-C interface, outputs a first voltage obtained from an external power source to the signal processing module to enter an emergency reverse power supply mode. It should be noted that the connection between the charging interface and the charging controller is bidirectional.

[0030] In other embodiments of this application, reference is made to Figure 3 As shown, the signal processing module 12 includes: a voltage processor 121 and a first diode 122, wherein: The first terminal of the voltage processor 121 is connected to the other terminal of the charging controller 112, and the second terminal of the voltage processor 121 is connected to the input terminal of the first diode 122. The output terminal of the first diode 122 is connected to the power module 13 and is used to prevent the power module from outputting a voltage signal to the voltage processor when the power module has voltage.

[0031] Specifically, the voltage processor can adjust, convert, or stabilize the input first voltage to ensure that the second voltage input to subsequent circuit modules has appropriate amplitude and stability to meet power quality requirements. In emergency jump-start scenarios, the voltage processor can adjust the first voltage to a second voltage that meets the requirements of the vehicle's low-voltage power network, thereby ensuring the normal operation of subsequent circuit modules. It should be noted that the internal circuitry of the voltage processor may include power supply circuits capable of boosting and / or bucking voltage.

[0032] In other embodiments of this application, the voltage processor can output the processed second voltage to the first diode, and then output it to the power module via the first diode. It should be noted that the first diode can be a unidirectional semiconductor device, allowing current to flow in only one direction and preventing reverse current from passing through.

[0033] In this embodiment, the first diode is positioned between the voltage processor and the power module, serving as a key component for reverse current protection. When the power module itself has an operating voltage, the first diode is reverse-biased and cut off, thereby preventing the voltage from the power module from flowing back to the voltage processor and upstream circuits, avoiding circuit damage or interference, and ensuring that the entire circuit operates in the expected state.

[0034] It should be noted that when the electric vehicle is out of power, the power bank is connected via the Type-C interface, such as... Figure 3 and Figure 5 The voltage processor processes the first voltage and then supplies power to the power module VIN via the first diode. When the power module VIN is in a normal power supply state, the voltage of the power module will not flow back to the voltage processor because the first diode is in a reverse cutoff state at this time.

[0035] In other embodiments of this application, the voltage processor can adjust the magnitude of the output voltage by... Figure 3The values ​​of resistors R5 and R7 are determined by the voltage processor adjusting the output voltage, which depends on the voltage value required by the target component. Therefore, the values ​​of resistors R5 and R7 can be set according to the voltage value required by the target component.

[0036] In other embodiments of this application, reference is made to Figure 4 As shown, the signal processing module 12 further includes: a second diode 123, wherein: The input terminal of the second diode 123 is connected to the second terminal of the charging interface 111, and the output terminal of the second diode 123 is connected to the first terminal of the voltage processor 121. The second diode 123 is used to protect the charging controller.

[0037] The second diode is a Schottky diode, which can control the unidirectional flow of current and is used as a protective element. Specifically, for example... Figure 5 and Figure 6 The second diode shown receives a first voltage input from an external power source (such as a power bank), and the output of the second diode is connected to the first terminal of the voltage processor, directing the current to the voltage processor for subsequent voltage processing.

[0038] It should be noted that the second diode allows the first voltage input from the Type-C interface to be output to the voltage processor in the subsequent circuit without flowing into the charging controller, thus bypassing the power transistor inside the charging controller.

[0039] In this embodiment, when the first voltage VBUS output from the Type-C interface passes through the second diode, it reaches the other port BUCK_OUT of the charging controller. The charging controller has a built-in power MOSFET, and the parasitic diode of the internal power MOSFET has the same path as the second diode. However, the forward voltage of the second diode is lower than that of the parasitic diode of the internal power MOSFET of the charging controller. When there is voltage on VBUS, because the forward voltage of the second diode is lower, the first voltage is output to the voltage processor through the second diode, and will not flow through the parasitic diode of the internal power MOSFET of the charging controller, thus preventing the parasitic diode of the internal power MOSFET of the charging controller from being damaged due to heat.

[0040] In other embodiments of this application, reference is made to Figure 5 As shown, the power supply device also includes: a power controller 14, wherein: The input terminal of the power controller 14 is connected to the power module 13, and the output terminal of the power controller 14 is connected to the other end of the charging controller 112.

[0041] Specifically, the power controller can be used to output a high-power signal for fast charging when the power module can provide normal voltage.

[0042] It should be noted that the internal circuitry of the power controller may include a BUCK circuit, which can output BUCK_VOUT power. This power is used to supply the Type-C fast charging protocol circuitry and Type-C interface of subsequent circuits when the power module can provide normal voltage, thereby enabling power supply or fast charging of external devices connected to the Type-C interface. Of course, the power module can refer to a low-voltage power supply.

[0043] In other embodiments of this application, reference is made to Figure 6 As shown, the power supply device also includes: a logic controller 15, wherein: The logic controller 15 is connected to the power module 13 and is used to control the target component to be in working mode when it receives the second voltage output by the power module.

[0044] Specifically, the logic controller is an electronic control unit that can receive the second voltage output from the power module and control the target component to be in operation according to preset conditions.

[0045] In this embodiment of the application, the core function of the logic controller is to start or activate the working mode of the target component after detecting a specific voltage signal (i.e., the second voltage), thereby ensuring that the target component of the electric vehicle can operate normally in an emergency.

[0046] In one feasible embodiment, in the scenario of electric vehicle power depletion, the target component includes a lock. When an external power source supplies power to the vehicle through a Type-C interface and outputs a second voltage, the logic controller recognizes the second voltage signal and controls the target component of the electric vehicle (e.g., the lock) to enter the working state. At this time, the lock can be unlocked, and after unlocking, the electric vehicle can be charged or a new power battery can be replaced.

[0047] In other embodiments of this application, the logic controller 15 is further configured to control the target component to be in a working module after the identity information of the terminal connected to the driving device is verified, so that the terminal can charge the driving device through the target component.

[0048] In this context, "terminal" can refer to an external electronic device that communicates with the driving equipment; in one possible embodiment, "terminal" can refer to the terminal of a user using the driving equipment.

[0049] Specifically, identity information can refer to information that can uniquely identify the identity of the connected terminal; identity verification refers to the process of securely authenticating the identity of the connected terminal to ensure that only authorized devices can trigger the emergency jump-start unlock function.

[0050] It should be noted that identity verification can be achieved through methods such as preset keys, Bluetooth pairing, NFC identification, QR code scanning, or cloud authentication. In one feasible embodiment, the identifier of the terminal's built-in security chip can be read and compared with a whitelist stored locally on the vehicle. If the comparison is successful, the terminal's identity verification is confirmed. Alternatively, an encrypted channel can be established via Bluetooth to complete two-way identity confirmation. By verifying identity information, the abuse of the emergency power supply function by unauthorized terminals can be effectively prevented, ensuring the safety of the vehicle.

[0051] In other embodiments of this application, once the electric vehicle's power source is in place, the low-voltage power network can resume normal operation, at which point the emergency jump-start mode ends.

[0052] The power supply device provided in the embodiments of this application allows the signal processing module to receive the first voltage output from the external power supply connected to the charging module when the power module fails to provide the working voltage normally. The signal processing module then outputs the processed second voltage to the power module, thereby enabling the power module to provide a second voltage lower than the working voltage to the target components of the driving device. This ensures that key components such as locks can work normally, thus solving the problem in the related technology that the power supply scheme for electric vehicles cannot provide effective emergency power supply when the whole vehicle is powered down, and ensuring the normal use of the electric vehicle.

[0053] Based on the foregoing embodiments, embodiments of this application provide a driving device, referring to... Figure 7 As shown, the driving device may include target component 2 and Figure 1 , 2 The power supply device 1 provided in embodiments 5 and 6, wherein: Power supply device 1 is used to output a second voltage to the target component based on a first voltage of the external power supply when an external power supply is connected. Target component 2 is used to switch to the operating mode based on the second voltage.

[0054] Specifically, the driving device can refer to a two-wheeled electric vehicle; the power supply device can enter an emergency jump-start mode when the electric vehicle's power battery is depleted, and provide a suitable voltage to the target component through an external power source to ensure the normal operation of the target component; thus, the user can perform operations such as charging the electric vehicle through the target component to use the electric vehicle normally.

[0055] The driving device provided in the embodiments of this application, when the power module of the driving device cannot provide the working voltage normally, the signal processing module of the power supply device can receive the first voltage output by the external power supply connected to the charging module of the power supply device, and output the processed second voltage to the power module. Then the power module of the power supply device can provide a second voltage lower than the working voltage to the target component of the driving device, so that key components such as locks can work normally. This solves the problem that the power supply scheme of electric vehicles in the related technology cannot provide effective emergency power supply when the whole vehicle is powered down, and ensures the normal use of electric vehicles.

[0056] Based on the foregoing embodiments, embodiments of this application provide a power supply method, which can be applied to... Figure 7 In the corresponding embodiment of the driving device, refer to Figure 8 As shown, the method includes the following steps: Step 101: When the power supply in the driving equipment is unavailable and an external power supply is available, obtain the first voltage of the external power supply.

[0057] In this context, the power supply in the driving equipment can refer to a low-voltage power supply, which can be the power supply that powers the entire vehicle; the inability to supply power can be due to abnormal conditions such as power failure; the driving equipment can refer to a two-wheeled electric vehicle.

[0058] Specifically, an external power source can refer to a device with a certain battery capacity and output capability, which can be used as a temporary power source when the vehicle's power supply is unavailable.

[0059] Step 102: Process the first voltage to obtain the second voltage.

[0060] Specifically, the first voltage can be stepped down and / or stepped up to obtain the second voltage.

[0061] It should be noted that the second voltage is adapted to the voltage required for the normal operation of the target component. Generally, the voltage required for the normal operation of the target component is relatively small. Therefore, the second voltage only needs to ensure that the target component can operate normally, without providing power to other components of the driving device. This achieves the goal of driving the target component with minimal power consumption.

[0062] In other embodiments of this application, the second voltage is lower than the operating voltage of the driving device when it is operating normally.

[0063] Step 103: The target component of the driving device is in working mode based on the second voltage control.

[0064] Specifically, after obtaining the second voltage, the target component of the driving equipment can be controlled to be in working state, that is, normal operation; thus, the user can charge the driving equipment or replace the power battery through the target component to ensure the normal use of the driving equipment.

[0065] In other embodiments of this application, step 103 described above can be implemented in the following ways: A1. Obtain the identity information of the terminal connected to the driving equipment and verify the identity information.

[0066] Here, "terminal" can refer to the device of a user using the driving equipment; "terminal" can refer to a device that has established a communication connection with the driving equipment.

[0067] Specifically, after the driving equipment receives the second voltage, it can obtain the terminal's identity information and perform authentication and other verification operations on the terminal's identity information.

[0068] A2. If the identity information is verified, the target component is switched to the working mode based on the second voltage control.

[0069] Specifically, once the terminal's identity information is verified, it indicates that the terminal is legitimate and capable of operating the driving equipment; at this point, the target component can be controlled to enter working mode.

[0070] In one feasible embodiment, if the target component includes a lock, the terminal can unlock the lock, allowing the user to insert the power battery or turn on the power battery, thereby ensuring the normal use of the electric vehicle.

[0071] It should be noted that the explanation of the relevant information and the steps performed in this embodiment can be referred to the description in the above embodiments, and will not be repeated here.

[0072] The power supply method provided in the embodiments of this application allows the signal processing module of the power supply device to receive a first voltage output from an external power source connected to the charging module of the power supply device when the power module of the driving device cannot provide a normal operating voltage. The processed second voltage is then output to the power module, which in turn can provide a second voltage lower than the operating voltage to the target components of the driving device. This enables key components such as locks to operate normally, thereby solving the problem in related technologies where electric vehicle power supply schemes cannot provide effective emergency power when the entire vehicle is powered down, and ensuring the normal use of the electric vehicle.
