[0047] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0048] Figure 1 FIG. 1 is a schematic diagram of a power supply control process provided by an exemplary embodiment of the present application. Figure 1As shown, when the vehicle 101 is not sold, the on-board controller will control the vehicle 101 to enter the pre-sale mode. When the vehicle 101 is in the pre-sale mode, the on-board controller will control the target power supply 102 to supply power to the target device in the vehicle 101. Specifically, when the vehicle 101 is electrically connected to the target power supply 102, the on-board controller is powered by the target power supply 102. The target device includes a device in the vehicle 101 whose operating voltage matches the voltage of the built-in low-voltage power supply 102 of the vehicle 101. The target power supply 102 is a power supply that is different from the built-in low-voltage power supply 103 of the vehicle 101 and has the same voltage as the built-in low-voltage power supply 103 of the vehicle 101. The voltage of the built-in low-voltage power supply 103 of the vehicle 101 is lower than the built-in high-voltage power supply 104 of the vehicle 101. In some embodiments, the target device includes the door lock controller, door and window controller, central control screen, button controller, etc. of the vehicle 101.

[0049] In some embodiments, the target power source 102 is an external power source for the vehicle 101. This external power source is electrically connected to the vehicle 101 via the charging port 105 of the vehicle 101 to power the target device in the vehicle 101. The charging port 105 is used to charge the internal high-voltage power source 104 of the vehicle 101. The charging port 105 has connection holes corresponding to the positive and negative poles of the target power source 102, and the positive and negative poles of the target power source 102 are electrically connected to these connection holes. In some embodiments, when the vehicle 101 is in pre-sale mode, the onboard controller disconnects control of the electrical control device corresponding to the charging port 105. The electrical control device is used to electronically control the opening and closing of the corresponding charging port cover of the charging port 105, i.e., electrically control the opening and closing of the charging port cover. The charging port cover also has a corresponding mechanical control structure for mechanically controlling the opening and closing of the charging port cover. When the vehicle 101 is in pre-sale mode, the opening and closing of the charging port cover can be directly controlled by the mechanical control structure. In some embodiments, when the target power supply 102 is used to supply power to a target device in the vehicle 101 to start the vehicle 101, the onboard controller stops controlling the target power supply 102 to supply power to the target device in the vehicle 101 and controls the built-in high-voltage power supply 104 of the vehicle 101 to supply power to the target device in the vehicle 101. In some embodiments, when the vehicle 101 is started, the onboard controller controls the built-in high-voltage power supply 104 to charge the target power supply 102.

[0050] By controlling the vehicle to enter a pre-sale mode before it is sold, and replacing the vehicle's built-in low-voltage power supply with a target power source other than the vehicle's built-in low-voltage power supply while the vehicle is in pre-sale mode, the vehicle can be used normally before it is sold without using the vehicle's built-in low-voltage power supply, thereby preventing the performance of the vehicle's built-in low-voltage power supply from being damaged before the vehicle is sold.

[0051] Figure 2 FIG. 1 is a flow chart of a power supply control method provided by an exemplary embodiment of the present application. The method can be used in a vehicle, such as an onboard controller of a vehicle. Figure 2 As shown, the method includes:

[0052] Step 202: If the vehicle has not been sold, control the vehicle to enter a pre-sale mode.

[0053] The vehicle in the embodiments of the present application includes at least one of a three-wheeled vehicle, a four-wheeled vehicle, and a vehicle with a greater number of wheels. The drive form of the vehicle includes at least one of front-wheel drive, rear-wheel drive, four-wheel drive, and multi-wheel drive. The power source of the vehicle includes electrical energy. In some embodiments, the vehicle in the embodiments of the present application includes but is not limited to a pure electric vehicle, a plug-in hybrid vehicle, and an extended-range hybrid vehicle. In some embodiments, the vehicle in the embodiments of the present application refers to an electric vehicle. The on-board controller is a controller integrated in the vehicle for controlling and managing vehicle components. The on-board controller may also be referred to as a vehicle controller.

[0054] An unsold vehicle includes at least one of the following: the vehicle has not been purchased by the intended user or has not been delivered to the intended user. Optionally, if the vehicle is unsold, staff can flash the vehicle's onboard controller, causing it to enter pre-sale mode. Pre-sale mode can also be understood as at least one of a pre-sale state, a pre-sale mode, and a pre-sale state.

[0055] In some embodiments, before or before the vehicle is delivered to the intended user, the onboard controller controls the vehicle to exit the pre-sale mode. Alternatively, when the vehicle is sold, the staff can flash the onboard controller of the vehicle so that the onboard controller controls the vehicle to exit the pre-sale mode.

[0056] For the characteristics of the vehicle in the pre-sale mode, please refer to the relevant content below, and the embodiments of the present application will not be introduced here.

[0057] Step 204 : When the vehicle is in the pre-sale mode, control the target power supply to supply power to the target device in the vehicle.

[0058] The target power supply is a power supply electrically connected to the vehicle. When the target power supply is electrically connected to the vehicle, the target power supply can power the vehicle's onboard controller, so that the onboard controller can control the target power supply to power the target device in the vehicle.

[0059] In some embodiments, the onboard controller controls the target power supply to supply power to the target device in the vehicle only when the vehicle is in pre-sale mode and electrically connected to the target power supply. In other embodiments, the onboard controller controls the target power supply to supply power to the target device in the vehicle as long as the vehicle is electrically connected to the target power supply, regardless of whether the vehicle is in pre-sale mode or not.

[0060] Target devices include devices in a vehicle whose operating voltage matches the voltage of the vehicle's built-in low-voltage power supply. The vehicle's built-in low-voltage power supply is a power supply built into the vehicle to power the target device. Matching the operating voltage with the voltage of the built-in low-voltage power supply means that the operating voltage is the same as the voltage of the built-in low-voltage power supply or the voltage of the built-in low-voltage power supply is included in the operating voltage range. In some embodiments, the voltage of the vehicle's built-in low-voltage power supply is 12V, which can be called a 12V power supply or a 12V battery. In some embodiments, the target devices in the vehicle include the vehicle's door lock controller, door and window controller, central control screen, button controller, etc.

[0061] It should be noted that when the vehicle is in pre-sale mode, the on-board controller can control the disconnection of the electrical connection with the vehicle's built-in low-voltage power supply; or, when the vehicle is in pre-sale mode, no built-in low-voltage power supply is provided in the vehicle, and after the vehicle exits pre-sale mode, a built-in low-voltage power supply is provided in the vehicle; or, when the vehicle is in pre-sale mode, a built-in low-voltage power supply is provided in the vehicle, but it is not electrically connected to the vehicle.

[0062] The target power supply is a power supply different from the vehicle's built-in low-voltage power supply, and the target power supply is a power supply with the same voltage as the vehicle's built-in low-voltage power supply. Since the target power supply has the same voltage as the vehicle's built-in low-voltage power supply, it can replace the vehicle's built-in low-voltage power supply to supply power to the target device in the vehicle. The vehicle is also provided with a built-in high-voltage power supply, and the voltage of the built-in low-voltage power supply is lower than the vehicle's built-in high-voltage power supply. In some embodiments, the vehicle's built-in high-voltage power supply is used to provide electrical energy for the vehicle's driving force, for example, for providing electrical energy for the vehicle's drive motor. In some embodiments, the vehicle's built-in high-voltage power supply can be referred to as a power power supply, a high-voltage battery, or a power battery.

[0063] In some embodiments, the target power source is an external power source for the vehicle. An external power source refers to a power source located outside the vehicle and electrically connected to the vehicle through the vehicle's charging port. The vehicle's charging port is used to charge the vehicle's internal high-voltage power source and may also be referred to as a fast-charging port. The charging port has connection holes corresponding to the positive and negative poles of the target power source. When the vehicle is electrically connected to the target power source, the positive and negative poles of the target power source are electrically connected to the connection holes in the charging port.

[0064] In some embodiments, when the vehicle is in pre-sale mode, the onboard controller disconnects control of the electrical control device corresponding to the charging port. The electrical control device corresponding to the charging port is used to electronically control the opening and closing of the corresponding charging port cover. That is, the onboard controller can electronically control the electrical control device corresponding to the charging port to control the opening and closing of the corresponding charging port cover. For example, when the charging port cover is open, the charging port is exposed on the surface of the vehicle; when the charging port cover is closed, the charging port cover covers the charging port, thereby obscuring the charging port from the surface of the vehicle.

[0065] In some embodiments, the charging port cover has a corresponding mechanical control structure, which is used to mechanically control the opening and closing of the charging port cover. Exemplarily, by pressing the charging port cover, the mechanical control structure can control the charging port cover to switch between open and closed. Optionally, the mechanical control structure includes at least one of a spring, a buckle, and a pull rod. When the charging port cover is pressed, the buckle can be triggered to lock, so that the charging port cover is closed; or, when the charging port cover is pressed, the buckle can be triggered to unlock, so that the pull rod is pushed under the action of the spring, so that the charging port cover is pushed out by the pull rod, thereby opening the charging port cover. Since when the vehicle is in pre-sale mode, the on-board controller will disconnect the control of the electrical control device corresponding to the charging port, the charging port cover can be opened or closed by the mechanical control structure corresponding to the charging port cover.

[0066] In some embodiments, when the target device is powered by the target power supply to start the vehicle, the on-board controller will control the vehicle's built-in high-voltage power supply to power the target device in the vehicle. Optionally, the vehicle can be started by powering the button controller corresponding to the vehicle's central control screen or start button through the target power supply. Optionally, in the process of controlling the vehicle's built-in high-voltage power supply to power the target device in the vehicle, the on-board controller will change the voltage of the electric energy provided by the built-in high-voltage power supply through the transformer circuit to power the target device in the vehicle. In some embodiments, when the vehicle is started, the vehicle's built-in high-voltage power supply will be activated to supply power to the outside. The process of activating the built-in high-voltage power supply to supply power to the outside can be achieved by the on-board controller controlling the target power supply.

[0067] In some embodiments, when the vehicle is started, the on-board controller controls the built-in high-voltage power supply to charge the target power supply. Optionally, when the vehicle is started, the vehicle is electrically connected to the target power supply, and the charging conditions are met, the on-board controller controls the built-in high-voltage power supply to charge the target power supply. The charging conditions include at least one of the remaining power of the built-in high-voltage power supply being greater than a first threshold and the remaining power of the target power supply being less than a second threshold. In some embodiments, the first threshold and the second threshold are set by the on-board controller, for example, by the user of the vehicle through the on-board controller.

[0068] In summary, the method provided in this embodiment controls the vehicle to enter a pre-sale mode before it is sold. While in pre-sale mode, the vehicle's built-in low-voltage power supply is replaced with a target power source other than the vehicle's built-in low-voltage power supply. This ensures normal use of the vehicle before it is sold, while avoiding the use of the vehicle's built-in low-voltage power supply. This prevents the performance of the vehicle's built-in low-voltage power supply from being impaired before the vehicle is sold.

[0069] Figure 3 FIG. 1 is a flow chart of a power supply control method provided by an exemplary embodiment of the present application. The method can be used in a vehicle, such as an onboard controller of a vehicle. Figure 3 As shown, the method includes:

[0070] Step 302: If the vehicle has not been sold, control the vehicle to enter a pre-sale mode.

[0071] The vehicle in the embodiments of the present application includes at least one of a three-wheeled vehicle, a four-wheeled vehicle, and a vehicle with a greater number of wheels. The drive form of the vehicle includes at least one of front-wheel drive, rear-wheel drive, four-wheel drive, and multi-wheel drive. The power source of the vehicle includes electrical energy. In some embodiments, the vehicle in the embodiments of the present application includes but is not limited to a pure electric vehicle, a plug-in hybrid vehicle, and an extended-range hybrid vehicle. In some embodiments, the vehicle in the embodiments of the present application refers to an electric vehicle. The on-board controller is a controller integrated in the vehicle for controlling and managing vehicle components. The on-board controller may also be referred to as a vehicle controller.

[0072] An unsold vehicle includes at least one of the following: the vehicle has not been purchased by the intended user or has not been delivered to the intended user. Optionally, if the vehicle is unsold, staff can flash the vehicle's onboard controller, causing it to enter pre-sale mode. Pre-sale mode can also be understood as at least one of a pre-sale state, a pre-sale mode, and a pre-sale state.

[0073] In some embodiments, before or before the vehicle is delivered to the intended user, the onboard controller controls the vehicle to exit the pre-sale mode. Alternatively, when the vehicle is sold, the staff can flash the onboard controller of the vehicle so that the onboard controller controls the vehicle to exit the pre-sale mode.

[0074] For the characteristics of the vehicle in the pre-sale mode, please refer to the relevant content below, and the embodiments of the present application will not be introduced here.

[0075] Step 304 : When the vehicle is in the pre-sale mode, control the target power supply to supply power to the target device in the vehicle.

[0076] The target power supply is a power supply electrically connected to the vehicle. When the target power supply is electrically connected to the vehicle, the target power supply can power the vehicle's onboard controller, so that the onboard controller can control the target power supply to power the target device in the vehicle.

[0077] In some embodiments, the onboard controller controls the target power supply to supply power to the target device in the vehicle only when the vehicle is in pre-sale mode and electrically connected to the target power supply. In other embodiments, the onboard controller controls the target power supply to supply power to the target device in the vehicle as long as the vehicle is electrically connected to the target power supply, regardless of whether the vehicle is in pre-sale mode or not.

[0078] Target devices include devices in a vehicle whose operating voltage matches the voltage of the vehicle's built-in low-voltage power supply. The vehicle's built-in low-voltage power supply is a power supply built into the vehicle to power the target device. Matching the operating voltage with the voltage of the built-in low-voltage power supply means that the operating voltage is the same as the voltage of the built-in low-voltage power supply or the voltage of the built-in low-voltage power supply is included in the operating voltage range. In some embodiments, the voltage of the vehicle's built-in low-voltage power supply is 12V, which can be called a 12V power supply or a 12V battery. In some embodiments, the target devices in the vehicle include the vehicle's door lock controller, door and window controller, central control screen, button controller, etc.

[0079] It should be noted that when the vehicle is in pre-sale mode, the on-board controller can control the disconnection of the electrical connection with the vehicle's built-in low-voltage power supply; or, when the vehicle is in pre-sale mode, no built-in low-voltage power supply is provided in the vehicle, and after the vehicle exits pre-sale mode, a built-in low-voltage power supply is provided in the vehicle; or, when the vehicle is in pre-sale mode, a built-in low-voltage power supply is provided in the vehicle, but it is not electrically connected to the vehicle.

[0080] The target power supply is a power supply different from the vehicle's built-in low-voltage power supply, and the target power supply is a power supply with the same voltage as the vehicle's built-in low-voltage power supply. Since the target power supply has the same voltage as the vehicle's built-in low-voltage power supply, it can replace the vehicle's built-in low-voltage power supply to supply power to the target device in the vehicle. The vehicle is also provided with a built-in high-voltage power supply, and the voltage of the built-in low-voltage power supply is lower than the vehicle's built-in high-voltage power supply. In some embodiments, the vehicle's built-in high-voltage power supply is used to provide electrical energy for the vehicle's driving force, for example, for providing electrical energy for the vehicle's drive motor. In some embodiments, the vehicle's built-in high-voltage power supply can be referred to as a power power supply, a high-voltage battery, or a power battery.

[0081] In some embodiments, the target power source is an external power source for the vehicle. An external power source refers to a power source located outside the vehicle and electrically connected to the vehicle through the vehicle's charging port. The vehicle's charging port is used to charge the vehicle's internal high-voltage power source and may also be referred to as a fast-charging port. The charging port has connection holes corresponding to the positive and negative poles of the target power source. When the vehicle is electrically connected to the target power source, the positive and negative poles of the target power source are electrically connected to the connection holes in the charging port.

[0082] For example, Figure 4 This is a schematic diagram of the structure of an external power supply and a charging port provided by an exemplary embodiment of the present application. Figure 4 As shown, the external power supply 401 is a 12V power supply. The interface 402 of the external power supply 401 includes a 12V positive electrode (12+) and a 12V negative electrode (12-). The vehicle's charging port 403 also includes a 12V positive electrode (12+) and a 12V negative electrode (12-). By electrically connecting the 12V positive electrode (12+) in the interface 402 to the 12V positive electrode (12+) in the vehicle's charging port 403, and electrically connecting the 12V negative electrode (12-) in the interface 402 to the 12V negative electrode (12-) in the vehicle's charging port 403, the external power supply 401 can be electrically connected to the vehicle, thereby powering the target device in the vehicle.

[0083] In some embodiments, when the vehicle is in pre-sale mode, the onboard controller disconnects control of the electrical control device corresponding to the charging port. The electrical control device corresponding to the charging port is used to electronically control the opening and closing of the corresponding charging port cover. That is, the onboard controller can electronically control the electrical control device corresponding to the charging port to control the opening and closing of the corresponding charging port cover. For example, when the charging port cover is open, the charging port is exposed on the surface of the vehicle; when the charging port cover is closed, the charging port cover covers the charging port, thereby obscuring the charging port from the surface of the vehicle.

[0084] In some embodiments, the charging port cover has a corresponding mechanical control structure, which is used to mechanically control the opening and closing of the charging port cover. Exemplarily, by pressing the charging port cover, the mechanical control structure can control the charging port cover to switch between open and closed. Optionally, the mechanical control structure includes at least one of a spring, a buckle, and a pull rod. When the charging port cover is pressed, the buckle can be triggered to lock, so that the charging port cover is closed; or, when the charging port cover is pressed, the buckle can be triggered to unlock, so that the pull rod is pushed under the action of the spring, so that the charging port cover is pushed out by the pull rod, thereby opening the charging port cover. Since when the vehicle is in pre-sale mode, the on-board controller will disconnect the control of the electrical control device corresponding to the charging port, the charging port cover can be opened or closed by the mechanical control structure corresponding to the charging port cover.

[0085] In some embodiments, when the target device is powered by the target power supply to start the vehicle, the on-board controller will control the vehicle's built-in high-voltage power supply to power the target device in the vehicle. Optionally, the vehicle can be started by powering the button controller corresponding to the vehicle's central control screen or start button through the target power supply. Optionally, in the process of controlling the vehicle's built-in high-voltage power supply to power the target device in the vehicle, the on-board controller will change the voltage of the electric energy provided by the built-in high-voltage power supply through the transformer circuit to power the target device in the vehicle. In some embodiments, when the vehicle is started, the vehicle's built-in high-voltage power supply will be activated to supply power to the outside. The process of activating the built-in high-voltage power supply to supply power to the outside can be achieved by the on-board controller controlling the target power supply.

[0086] Step 306: When the vehicle is started, control the built-in high-voltage power supply to charge the target power supply.

[0087] Optionally, when the vehicle is started, electrically connected to the target power source, and charging conditions are met, the onboard controller controls the built-in high-voltage power source to charge the target power source. The charging conditions include at least one of the remaining charge of the built-in high-voltage power source being greater than a first threshold and the remaining charge of the target power source being less than a second threshold. Optionally, the first and second thresholds are set by the onboard controller, for example, by the user of the vehicle. In some embodiments, the target power source is mounted on the vehicle, for example, by being mounted on the vehicle surface. When the vehicle is started and the vehicle speed is below a speed threshold, the onboard controller controls the built-in high-voltage power source to charge the target power source. Optionally, the speed threshold is set by the onboard controller, for example, by the user of the vehicle. When the target power source is mounted on the vehicle, since high vehicle speeds can affect the stability of the target power source connection, reverse charging the target power source via the built-in high-voltage power source at lower vehicle speeds can ensure safety during the charging process.

[0088] In some embodiments, the target power source is equipped with a locator, which is used to determine the target power source's location. The vehicle is also equipped with a locator, which is used to determine the vehicle's location. Optionally, the onboard controller can obtain the vehicle's location through the vehicle's locator. The onboard controller can obtain the target power source's location through the target power source's locator. A communication connection is established between the onboard controller and the locator in the target power source, for example, via short-range communication technology. If the distance between the target power source's current location, determined by the target power source's locator, and the vehicle's historical location is less than a distance threshold, and the vehicle's charging port is not connected to a power source, the onboard controller will send a prompt message. The historical location is the vehicle's most recent location determined by the onboard controller. The onboard controller can determine whether the vehicle's charging port is connected to a power source using detection circuitry installed in the vehicle's charging port. The prompt message is used to prompt the user to reconnect the target power source. Optionally, the onboard controller establishes a communication connection with a terminal of a user of the vehicle. If the above conditions are met, the onboard controller will send a prompt message to the user's terminal to notify the user if the target power source may be abnormally disconnected.

[0089] For example, Figure 5 FIG. 1 is a schematic diagram of a process of sending prompt information provided by an exemplary embodiment of the present application. Figure 5 As shown, when the current position of the target power source 502 of the vehicle 501 is less than the distance 503 from the historical position of the vehicle 501 and the on-board controller detects that the charging port 504 of the vehicle 501 is not connected to the power source, the on-board controller will send a prompt message to the terminal 505 of the user of the vehicle 501 to prompt that the target power source 502 may be abnormally disconnected and the target power source 502 needs to be reconnected.

[0090] In some embodiments, a power generation element and a battery are provided on the surface of the vehicle, and the power generation element is used to generate electricity based on the temperature difference. Optionally, the power generation element is a semiconductor material that generates electricity through the thermoelectric effect. For example, the power generation element can generate electricity through the Seebeck effect. The Seebeck effect refers to the fact that when there is a temperature difference between the two ends of two different conductors or semiconductor materials, carriers (electrons) will diffuse from the high-temperature end to the low-temperature end, forming an electric potential difference, and the voltage generated is proportional to the temperature difference. The power generation element can also generate electricity through the Peltier effect. The Peltier effect refers to the phenomenon of heat absorption or heat release when current passes through the contact surface of two materials. The reverse process is used in thermoelectric power generation to achieve the conversion of thermal energy into electrical energy. When the temperature of the vehicle surface changes, the power generation element will generate electricity based on the temperature difference, and the on-board controller will store the electricity generated by the power generation element in the battery. The battery is used to charge the target power supply. That is, when the battery stores electrical energy, the on-board controller will control the battery to charge the target power supply. When the vehicle is in pre-sale mode, it may be parked outdoors for a long time. By utilizing temperature differences (such as day and night temperature differences) to store electrical energy in the battery to charge the target power source, the target power source can be prevented from being depleted.

[0091] In summary, the method provided in this embodiment controls the vehicle to enter a pre-sale mode before it is sold. While in pre-sale mode, the vehicle's built-in low-voltage power supply is replaced with a target power source other than the vehicle's built-in low-voltage power supply. This ensures normal use of the vehicle before it is sold, while avoiding the use of the vehicle's built-in low-voltage power supply. This prevents the performance of the vehicle's built-in low-voltage power supply from being impaired before the vehicle is sold.

[0092] The method provided in this embodiment also electrically connects an external power source to the vehicle's charging port to power the vehicle's target device. By reusing the charging port, the external power source can be connected without modifying the vehicle's structure. By disconnecting control of the electrical control device corresponding to the charging port when the vehicle is in pre-sale mode, the charging port cover can be flexibly opened and closed in the absence of power to meet the need for connecting to an external power source. By reverse charging the target power source through the vehicle's built-in high-voltage power supply when the vehicle is started, the target power source can be prevented from running low.

[0093] Taking the method provided in this application as an example of applying it to electric vehicles, this application realizes the use of an existing electric vehicle fast charging interface to obtain a 12V power supply from the outside, and then through the mode setting of the vehicle controller, it is possible to start and use the vehicle before it is sold to the customer without using the built-in 12V power supply, which is convenient for lightering. At the same time, it can prevent the built-in 12V power supply from running out of power in the case of long-term parking and freight transportation. The following is an exemplary introduction to the application scenarios involved in this application.

[0094] When a new vehicle is assembled, the vehicle controller defaults to pre-sales mode, where the charging port cover is not controlled. Regardless of the vehicle's operating state, if the charging port cover is closed, it can be opened by pressing the cover. If it is open, it can be closed by pressing the cover. The opening and closing of the charging port cover are controlled by a mechanical mechanism.

[0095] The vehicle is not equipped with a built-in 12V power supply and is in the OFF state (the high-voltage power supply is not powered). At this time, open the charging port cover, plug the 12V external power supply into the vehicle's fast charging port, and close the charging port cover. The low-voltage electrical appliances of the entire vehicle are powered by the 12V external power supply. The vehicle controller is powered on and started by the external 12V power supply. At this time, the door can be remotely unlocked and opened using the key that matches the vehicle. When the driver enters the vehicle, operates the vehicle to enter the READY state, and starts the high-voltage power supply system, the vehicle enters the operational mode. At this time, the vehicle is provided with the power required for driving the vehicle and the power required for the low-voltage power supply system by the high-voltage power supply. At this time, the vehicle can be operated normally.

[0096] When the vehicle enters the READY state, the 12V external power supply can be reverse charged through the low-voltage power supply converted from the high-voltage power supply.

[0097] After the driver parks the vehicle and turns off the vehicle, the vehicle enters a non-READY state, the high-voltage power supply stops supplying power to the vehicle, and the entire vehicle is powered by a 12V external power supply.

[0098] After the driver has completed the vehicle's operation and parks the vehicle, if he directly locks the vehicle, the vehicle will use the high-voltage power supply to provide low-voltage power to complete the automatic window raising and other operations, and then the high voltage power will be turned off. After that, the vehicle controller will consume power from the 12V external power supply.

[0099] The driver parks the vehicle, gets out, locks the vehicle, and the vehicle completes actions such as closing the windows by itself, and after the high voltage is turned off, the driver can unplug the 12V external power supply.

[0100] It should be noted that before collecting the user's relevant data and during the process of collecting the user's relevant data, this application can display a prompt interface, pop-up window or output voice prompt information. The prompt interface, pop-up window or voice prompt information is used to remind the user that its relevant data is currently being collected, so that this application only starts to execute the relevant steps of obtaining the user's relevant data after obtaining the user's confirmation operation on the prompt interface or pop-up window. Otherwise (that is, when the user's confirmation operation on the prompt interface or pop-up window is not obtained), the relevant steps of obtaining the user's relevant data are terminated, that is, the user's relevant data is not obtained. In other words, all user data collected by this application are collected with the user's consent and authorization, and the collection, use and processing of relevant user data need to comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0101] It should be noted that the order of the method steps provided in the embodiments of the present application can be appropriately adjusted, and the steps can be increased or decreased accordingly according to the circumstances. Any technical personnel familiar with this technical field can easily think of the changed methods within the technical scope disclosed in this application, and they should be covered within the scope of protection of this application, so they will not be repeated here.
