Description

Technical Field

[0001] The present disclosure relates to the technical field of electric vehicles, and in particular to an electric vehicle and a control device thereof. Background Art

[0002] Electric vehicles can achieve positioning through onboard Bluetooth. However, after Bluetooth positioning is achieved, the vehicle still needs to be manually started, and automatic startup after Bluetooth positioning is not possible. Furthermore, after the user turns off or locks the electric vehicle, the dashboard often needs to be powered to maintain Bluetooth positioning. The dashboard is typically powered by a controller, which requires a constant output voltage. This increases the power consumption of the electric vehicle and reduces its standby time. Utility Model Content

[0003] In view of this, the purpose of the present disclosure is to propose an electric vehicle and its control device to at least solve one of the technical problems such as increased power consumption and reduced standby time when the electric vehicle cannot automatically start, lock or shut down after Bluetooth positioning.

[0004] In a first aspect of the present disclosure, a control device for an electric vehicle is provided, comprising:

[0005] a battery module, configured to provide a first voltage;

[0006] a control module, connected to the battery module, and configured to control the operating state of the electric vehicle;

[0007] A functional module is connected to the control module and the battery module, the functional module operates based on the first voltage; and receives a first control signal and sends the first control signal to the control module to turn off the output of the control module.

[0008] A second aspect of the present disclosure provides an electric vehicle comprising the control device as described in the first aspect.

[0009] As can be seen from the above, the electric vehicle and its control device provided by the present disclosure directly supply power to the control module and the functional module through the battery module, so that when the vehicle is locked or turned off, the power supply to the control module can be turned off and the power supply to the functional module can be maintained. In this way, by turning off the power output of the control module when the vehicle is shut down or locked, the standby power consumption is reduced, and the power management efficiency and user experience are improved. Compared with the prior art in which the vehicle maintains a continuous voltage output in order to maintain the power supply to the functional module when the vehicle is shut down or locked, the technical solution of the present disclosure can reduce the power consumption of the electric vehicle after shutting down or locking the vehicle and increase the standby time. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] In order to more clearly illustrate the technical solutions in the present disclosure or related technologies, the following briefly introduces the drawings required for use in the embodiments or related technical descriptions. Obviously, the drawings described below are only embodiments of the present disclosure. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0013] In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0014] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present disclosure should have the usual meanings understood by people with ordinary skills in the field to which the present disclosure belongs. The "first", "second" and similar words used in the embodiments of the present disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0015] Currently, electric vehicles still need to be manually started after achieving positioning through onboard Bluetooth, and cannot be automatically powered on after Bluetooth positioning. In related technologies, in order to perform Bluetooth positioning functions, it is often necessary to maintain the power supply of the instrument panel. The instrument panel usually uses the voltage conversion circuit in the controller to convert the output voltage of the battery pack to power the instrument panel. This requires the controller to maintain a certain output voltage, such as Figure 1 As shown, Figure 1 A schematic diagram of a control device for an electric vehicle is shown. This will result in increased power consumption and reduced standby time for the electric vehicle. Therefore, how to reduce the power consumption of the electric vehicle and increase the standby time has become a technical problem that needs to be solved urgently.

[0016] In view of this, the electric vehicle and its control device provided by the present disclosure directly supply power to the control module and the functional module through the battery module, so that when the vehicle is locked or turned off, the power supply to the control module can be turned off, while the power supply to the functional module is maintained. In this way, by turning off the power output of the control module when the vehicle is shut down or locked, the standby power consumption is reduced, and the power management efficiency and user experience are improved. Compared with the prior art in which the vehicle maintains a continuous voltage output to maintain the power supply to the functional module when the vehicle is shut down or locked, the technical solution of the present disclosure can reduce the power consumption of the electric vehicle after shutting down or locking the vehicle and increase the standby time.

[0017] See also Figure 2 , Figure 2 The schematic diagram of the control device of an electric vehicle according to an embodiment of the present disclosure is shown. The control device 200 of an electric vehicle according to an embodiment of the present disclosure may include:

[0018] The battery module 210 is configured to provide a first voltage;

[0019] a control module 220 connected to the battery module 210 for controlling the operating state of the electric vehicle;

[0020] The functional module 230 is connected to the control module 220 and the battery module 210 , and operates based on the first voltage; and receives a first control signal and sends the first control signal to the control module 220 to shut down the output of the control module 220 .

[0021] The battery module 210 provides the necessary power for the entire system, ensuring the normal operation of the control module 220 and the functional module 230. The functional module 230 operates based on a first voltage and receives a first control signal for shutting down the control module 220. In some embodiments, the first control signal may come from a terminal, such as a smartphone, remote control, or other control device. In some embodiments, the first control signal may come from a switch on the electric vehicle. For example, a user can trigger the switch to generate the first control signal, thereby shutting down the output of the control module 220. The functional module 230 transmits the received first control signal to the control module 220 to shut down the output of the control module 220. For example, when a user sends a "shut down" command through the terminal, the command is transmitted to the control module 220 via the functional module 230, shutting down the output of the control module 220 and stopping the operation of the electric vehicle. Furthermore, the power supply of the functional module is decoupled from the control module, eliminating its dependence on the control module's output. This ensures that the functional module can still perform its specific functions even when the electric vehicle is shut down or locked, while reducing the power consumption of the electric vehicle in this state and increasing its standby time.

[0022] In some embodiments, the control module 220 includes a first voltage converter 221 for converting the first voltage into a second voltage to power the control module 220; wherein, the enable terminal EN of the first voltage converter 221 turns off the output of the first voltage converter 221 based on the first control signal to turn off the output of the control module 220.

[0023] The voltage converter's enable pin (EN) is a control pin used to turn the voltage converter's output on or off. By controlling the state of the enable pin, precise control of the voltage converter's output can be achieved. When the enable pin receives a high level, the voltage converter starts operating and outputs voltage; when the enable pin receives a low level, the voltage converter stops operating and the output voltage is turned off. This allows the start and stop of electric vehicles to be remotely controlled through the terminal, improving system reliability and safety. This eliminates the need for direct contact with the electric vehicle, simplifying user operations and enhancing the user experience. While ensuring that functional modules can still provide specific functions in the off or locked state, the power consumption of electric vehicles in the off or locked state is reduced, the standby time is increased, energy management is optimized, and the system's flexibility is enhanced.

[0024] In some embodiments, the functional module 230 includes a second voltage converter 231 and a communication module; wherein the second voltage converter 231 is connected to the battery module 210 and is configured to convert the first voltage into a third voltage to supply power to the functional module 230;

[0025] The communication module communicates with the control module 220 , and is configured to receive the first control signal and send the first control signal to the control module 220 .

[0026] The communication module can be wired communication or wireless communication, which is not limited here. Figure 2 As shown, the MCU-EN pin in the control module 220 can receive a first control signal from the terminal via the functional module 230, thereby pulling down the voltage of the enable terminal EN of the first voltage converter 221, so that the output of the enable terminal EN of the first voltage converter 221 is turned off.

[0027] In some embodiments, the enable terminal EN of the first voltage converter 221 is connected to the cathode of the first diode D2, the anode of the first diode D2 is connected to the first end of the first resistor R6, and the second end of the first resistor R6 (connected to the MCU-EN pin) receives the first control signal.

[0028] Figure 2In the example, the input terminal of the first voltage converter 221 in the control module 220 is connected to the positive output terminal P+ of the battery module 210, converting the first voltage outputted from the positive output terminal P+ into a second voltage output, for example, 12V. The input terminal of the second voltage converter 232 in the functional module 230 is connected to the positive output terminal P+ of the battery module 210, converting the first voltage outputted from the positive output terminal P+ into a third voltage, for example, 3.3V. The control module 220 can also receive a shutdown command or a vehicle lock command from a terminal via the communication module of the functional module 230 and transmit it to the MCU-EN pin in the control module 220. The MCU-EN pin then pulls down the voltage of the enable terminal EN of the first voltage converter 221, thereby shutting down the output of the first voltage converter 221. For example, a high-level signal at the MCU-EN pin turns on the first diode D2, and a low-level signal at the enable terminal EN of the first voltage converter 221 turns off the output of the first voltage converter 221. In this case, the first voltage converter 221 does not output the second voltage, and the power consumption of the electric vehicle is only that of the functional module 230. and Figure 1 Compared with the sum of the power consumption of the controller and the instrument panel in the vehicle, the solution disclosed in the present invention reduces the power consumption of the electric vehicle in the shutdown or locked state and increases the standby time.

[0029] In some embodiments, the user can also trigger a shutdown command or a vehicle lock command through the interactive switch 232, that is, a corresponding shutdown control signal, such as a low-level signal, is generated at the interactive switch 232. Based on the shutdown control signal, the control module 220 can lower the voltage of the enable terminal EN of the first voltage converter 221, thereby turning off the output 12V of the first voltage converter 221 and shutting down the output of the control module 220.

[0030] In some embodiments, a first voltage regulator is connected between the output terminal of the first voltage converter 221 and the equipotential terminal of the first voltage converter 221 .

[0031] The first voltage regulator can be analog or digital, and can ensure that the output voltage remains stable when the power supply voltage fluctuates or the load demand changes. Specifically, the first voltage regulator can be a linear voltage regulator, such as an LDO (Low Dropout Regulator), which can operate at a very low input-output voltage difference while providing a stable output voltage to maintain the output voltage at a constant level regardless of changes in the input voltage or load conditions. Specifically, Figure 2 As shown, the equipotential terminal of the first voltage converter 221 can be grounded. A first regulator LDO is connected between the output terminal output of the first voltage converter 221 and the equipotential terminal of the first voltage converter 221 to maintain output stability of the output terminal output.

[0032] In some embodiments, the functional module 230 includes:

[0033] The signal trigger circuit 233 is connected to the control module 220 and is configured to generate a second control signal to control the control module 220 to start in response to receiving an activation signal indicating that a preset function of the function module 230 is activated.

[0034] Among them, the preset function can refer to a function that has been deployed in the electric vehicle, such as Bluetooth positioning. Specifically, the user can send a preset function request based on the terminal, and when the electric vehicle receives the preset function request, it can wake up the preset function of the electric vehicle based on the function module. After the preset function is activated, the function module or the control module can generate a corresponding activation signal KEY-CON, and the activation signal KEY-CON can lower the voltage at the first terminal A of the interactive switch 232 to generate a second control signal, such as Figure 2 shown.

[0035] In some embodiments, the signal triggering circuit includes:

[0036] A first switch Q1, wherein a first end of the first switch Q1 is connected to the control module 220 via a second resistor R1, and a second end of the first switch Q1 is connected to a control end of the first switch Q1 via a third resistor R2, and the control end of the first switch Q1 is used to receive the activation signal KEY-CON.

[0037] In some embodiments, the functional module includes an interactive switch, a first end of which is connected to the second resistor in the signal trigger circuit and the second diode in the control module; and the interactive switch generates the second control signal based on user operation.

[0038] Specifically, see Figure 2 The control terminal of the first switch Q1 can also receive an activation signal KEY-CON via resistor R1'. This activation signal KEY-CON triggers the first switch Q1 to conduct, thereby lowering the voltage at the first terminal A of the interactive switch 232 and generating a second control signal, which can be a low-level signal. Based on this second control signal, the enable terminal EN of the first voltage converter 221 is a high-level signal, and the control module 220 is turned on, thereby achieving automatic starting of the electric vehicle after activating the preset function. Compared with the existing technology, the electric vehicle can be started without manual operation, simplifying user operation.

[0039] In some embodiments, the enable terminal EN of the first voltage converter 221 is further connected to the first terminal of the second switch Q3, the second terminal of the second switch Q3 is connected to the input terminal of the first voltage converter 221 via the fourth resistor R8, and the control terminal of the second switch is connected to the functional module 230 via the fifth resistor R9 and the second diode D3.

[0040] Specifically, if Figure 2 As shown, a first control signal, such as a high-level signal, is generated at the interactive switch 232. The MCU-EN terminal is a high-level signal, causing the second diode D2 to conduct, and the enable terminal EN of the first voltage converter 221 is a low-level signal, thereby shutting down the output of the first voltage converter 221. At this time, the output terminal "output" of the first voltage converter 221 has no output signal, reducing the power consumption of the controller in the electric vehicle in the locked or shut-down state while ensuring the normal operation of the functional modules. The first end of the third switch Q3 is also connected to the same potential (e.g., ground) via resistor R11, and the second end of the third switch Q3 is also connected to the same potential (e.g., ground) via resistor R12. Resistor R10 is connected between the second end of the third switch Q3 and the control terminal of the third switch Q3.

[0041] In some embodiments, the apparatus 200 further includes:

[0042] The first end A of the interactive switch 232 is connected to the cathode of the third diode D1, the anode of the third diode D1 is connected to the control end of the third switch Q2 via the sixth resistor R3, the sixth resistor R3 and the first end of the third switch Q2 are connected to the third voltage via the seventh resistor R4, and the second end of the third switch Q2 is connected to the second end B of the interactive switch 232 via the eighth resistor R5; the second end of the third switch Q2 outputs a display signal to control the functional module 230 to display the operating parameters of the electric vehicle.

[0043] Specifically, if Figure 2 As shown, when the first end A of the interactive switch 232 is a low-level signal, the third diode D1 is turned on, the control end of the third switch Q2 is a high-level signal, and the third switch Q2 is turned on. At this time, the second end of the third switch Q2 can output a display signal DISPLAY-KEY to display relevant parameters of the electric vehicle in the functional module. It should be understood that the first switch Q1, the second switch Q3, and the third switch Q2 in the embodiment of the present disclosure can be triodes or other switches, and are not limited here. Similarly, the first diode D2, the second diode D3, and the third diode D1 can all be voltage-stabilizing diodes or other diodes, and are not limited here.

[0044] In some embodiments, the preset function includes locating the electric vehicle based on a Bluetooth signal;

[0045] The functional module 230 further includes: a Bluetooth module 234; the control module 220 further includes a Bluetooth controller 222, which is connected to the Bluetooth module 234 to implement the preset function;

[0046] The Bluetooth module 234 is configured to send Bluetooth signals, receive terminal Bluetooth signals from the terminal for the Bluetooth module, and send the terminal Bluetooth signals to the Bluetooth controller 222;

[0047] The Bluetooth controller 222 is used to respond to the terminal Bluetooth signal,

[0048] A response signal indicating the positioning information of the electric vehicle is generated and sent to the terminal via the Bluetooth module.

[0049] The Bluetooth module 234 can broadcast Bluetooth signals to the corresponding terminal. Once the terminal receives the Bluetooth signal and successfully completes authentication, it can return a terminal Bluetooth signal. The Bluetooth module 234 can receive terminal Bluetooth signals from external devices (such as smartphones) and forward them to the Bluetooth controller 222. In response to these terminal Bluetooth signals, the Bluetooth controller 222 generates a response signal containing the electric vehicle's location information and sends it to the terminal, thereby helping the user locate the electric vehicle.

[0050] In some embodiments, the second voltage converter 231 includes: a DC converter and / or a second voltage regulator, configured to convert the first voltage into the third voltage to supply power to the Bluetooth module 234 .

[0051] Among them, the second voltage converter 231 can convert the first voltage output by the battery module 210 into a plurality of different operating voltages to meet the different levels of power supply requirements of each module, such as 3.3V, 5V, 6V, etc. In this way, the second voltage converter 231 in the functional module 230 is directly connected to the battery module 210, which can maintain the power supply of the Bluetooth module and ensure the execution of the Bluetooth positioning function. At the same time, there is no need to rely on the output of the control module 220, so that the control module 220 can not output voltage when locked or closed, reducing the power consumption of the electric vehicle and increasing the standby time. It should be understood that when the second voltage converter 231 includes a DC converter and a second voltage regulator, the DC converter and the second voltage regulator can be connected in series or in parallel, and there is no restriction here.

[0052] In some embodiments, the electric vehicle includes an electric scooter, and the functional module includes a dashboard for displaying operating parameters of the electric scooter; wherein the operating parameters include battery parameters of the battery module and operating parameters of the operating state of the electric scooter;

[0053] The interactive switch includes a push button switch on the instrument panel, which is used to turn the scooter on and off. Specifically, the electric scooter is a two-wheeled vehicle powered by a battery. An integrated instrument panel and push button switch can be integrated into the electric scooter, allowing users to view the vehicle's operating parameters and generate control signals through simple user operations to control functions such as locking or shutting down the vehicle. Specifically, the instrument panel displays battery module parameters (such as charge level and voltage) and the electric scooter's operating status parameters (such as speed and mileage). When the user presses the push button switch on the instrument panel or receives a control signal from the terminal, the vehicle can be locked or shut down, thereby saving power and extending standby time. Users can also activate the electric scooter's Bluetooth positioning function through an application on the terminal. The terminal receives the Bluetooth signal broadcast by the electric scooter and, after authentication, returns the terminal Bluetooth signal to the electric scooter. After receiving the terminal Bluetooth signal, the Bluetooth module on the electric scooter forwards it to the Bluetooth controller in the control module. The Bluetooth controller processes the request signal and generates a response signal based on the scooter's current location information. This response signal may include the electric scooter's location data. This response signal is then returned to the user's terminal via the Bluetooth module. The terminal's application can interpret this response signal and display the electric scooter's location to the user. Simultaneously, when the electric vehicle detects that the Bluetooth positioning function has been activated, it can trigger the circuit to lower the voltage of the push button switch, generating a second control signal to activate the control module and the electric vehicle, enabling automatic starting of the electric vehicle.

It should be understood that the electric vehicle according to the embodiment of the present disclosure may include an electric scooter, and may also include vehicles with other numbers of wheels, which are not limited here.
