[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This application provides a boot system 1, applied to a device 2 to be booted. Please refer to [link / reference]. Figure 1 , Figure 1This is a schematic diagram of a startup system framework provided in the first embodiment of this application. The startup system 1 includes a processor 11 and a positive connection detection module 12. The device to be started 2 includes a positive terminal CAR+ and a negative terminal CAR-. The processor 11 is electrically connected to the positive connection detection module 12. The positive connection detection module 12 includes a first detection submodule 121 and a first transistor 122. The first detection submodule 121 is used to detect electrical signals received by the positive terminal CAR+ and the negative terminal CAR-. When the first detection submodule 121 detects that the positive terminal CAR+ receives a positive electrical signal and the negative terminal CAR- receives a negative electrical signal, a positive connection signal is generated. The first detection submodule 121 sends the positive connection signal to the processor 11 through the first transistor 122, causing the processor 11 to enter a normal working state.

[0022] It should be noted that, in this embodiment, the device to be started 2 is an electronic device with a startable battery, such as an electric bicycle. The processor 11 is a chip with computing power. Typically, the electrical signals received by the positive electrode CAR+ and the negative electrode CAR- are provided by a power supply device other than the starting system 1, such as a battery; that is, the power supply device provides positive and negative electrical signals.

[0023] Specifically, when the positive CAR+ is connected to the positive electrical signal and the negative CAR- is connected to the negative electrical signal, the first detection submodule 121 generates the positive connection signal and sends it to the processor 11 through the first transistor 122.

[0024] Understandably, in this embodiment, since the first transistor 122 has the characteristic of fast turn-on or turn-off speed, by transmitting the positive connection signal to the processor 11, it can quickly respond to interrupt control, so as to prevent incorrect power connection from causing abnormal startup of system 1, and greatly improve the safety and reliability of the startup process.

[0025] In one possible embodiment, please refer to the following: Figure 2 , Figure 2This is a schematic diagram of a startup system framework provided in an embodiment of this application. The startup system 1 further includes a reverse connection detection module 13, which is electrically connected to the processor 11. The reverse connection detection module 13 includes a second detection submodule 131 and a second transistor 132. The second detection submodule 131 is used to detect electrical signals received by the positive CAR+ and the negative CAR-. When the second detection submodule 131 detects that the positive CAR+ is connected to a negative electrical signal and the negative CAR- is connected to a positive electrical signal, a reverse connection electrical signal is generated. The second detection submodule 131 sends the reverse connection electrical signal to the processor 11 through the second transistor 132, causing the processor 11 to enter an abnormal alert state.

[0026] Understandably, when the positive terminal CAR+ is connected to the negative electrical signal and the negative terminal CAR- is connected to the positive electrical signal, that is, the circuit of the device to be started 2 is reversed with the power supply, it will cause great damage to the electronic components in the device to be started 2. The second detection submodule 131 generates the reverse connection signal and sends it to the processor 11 through the second transistor 132. After the processor 11 enters the abnormality warning state, it can prevent the positive and negative electrical signals of the power supply from being connected to the device to be started 2, thereby protecting the electronic components in the device to be started 2.

[0027] Similar to the previous embodiment, in this embodiment, since the second transistor 132 has the characteristic of fast turn-on or turn-off speed, by transmitting the reverse connection electrical signal to the processor 11, it can quickly respond to interrupt control and prevent damage to electronic components caused by reverse connection with the power supply device.

[0028] In one possible embodiment, please refer to the following: Figure 3 , Figure 3 This is a schematic diagram of a startup system framework provided in an embodiment of this application. The startup system 1 further includes a voltage detection module 14, which is electrically connected to the processor 11. The voltage detection module 14 obtains the input voltage value based on the positive and negative electrical signals and sends the input voltage value to the processor 11 in real time. When the slope of the input voltage value drops to a preset slope threshold, and when the processor 11 is in normal working condition, the processor 11 controls the startup system 1 to work.

[0029] It should be noted that, in this embodiment, the startup system 1 further includes a control switch module 15. The positive and negative electrical signals are provided by a power supply device other than the startup system 1. Typically, the startup system 1 is applied to the device to be started 2, and the positive and negative electrical signals are loaded onto the device 2 through the startup system 1. When the device 2 is started, due to the new load, the voltage values ​​of the positive and negative electrical signals will begin to decrease. The voltage detection module 14 sends the input voltage value to the processor 11 in real time, and the processor 11 can calculate the slope of the input voltage decrease. The slope of the input voltage value can represent the resistance value in the circuit. When the slope of the input voltage value decreases to the preset slope threshold, that is, when a suitable starting resistance value is reached in the circuit, the processor 11 controls the control switch module 15 to turn on. It can be understood that the preset slope threshold can be changed depending on the device 2 to be started.

[0030] Specifically, the operation of the startup system 1 means that after the processor 11 controls the control switch module 15 to turn on, the positive electrical signal and the negative electrical signal will be loaded onto the positive CAR+ and the negative CAR- through the control switch module 15, so that the power supply device can start the device 2 to be started through the startup system 1.

[0031] In one possible embodiment, please refer to the following: Figure 4 , Figure 4 This is a schematic diagram of a startup system framework provided in an embodiment of this application. The startup system 1 further includes a button module 16, which is electrically connected to the processor 11. When the input voltage value is greater than or equal to a preset voltage threshold, and the button module 16 generates a button signal, the button module 16 sends the button signal to the processor 11. The processor 11 controls the startup system 1 to operate according to the button signal.

[0032] Specifically, unlike the previous embodiment, this embodiment uses a different startup method. It should be noted that in this embodiment, the startup system further includes a control switch module 15, and the positive and negative electrical signals are provided by the power supply device inside the startup system 1. Typically, the button module 16 also includes a button 161; when button 161 is pressed, the button module 16 generates the button signal. When the input voltage value is greater than or equal to the preset voltage threshold, that is, when the input voltage value meets the requirements for starting the device 2 to be started, and the button module 16 generates the button signal, the processor 11 controls the control switch module 15 to turn on according to the button signal, causing the startup system 1 to operate, so that the power supply device can start the device 2 to be started through the startup system 1. It can be understood that the preset voltage threshold can be changed according to different devices 2 to be started.

[0033] In one possible embodiment, please refer to the following: Figure 5 , Figure 5 This is a schematic diagram of a startup system framework provided in an embodiment of this application. The startup system 1 further includes a current detection module 17, which is electrically connected to the processor 11. When the startup system 1 is working, the current detection module 17 calculates the input current value based on the positive and negative electrical signals. When the input current value is greater than a preset current threshold, the current detection module 17 sends an interrupt signal to the processor 11. The processor 11 controls the startup system 1 to stop working based on the interrupt signal.

[0034] Specifically, in this embodiment, the startup system 1 further includes a control switch module 15. When the startup system 1 is working, that is, the device to be started 2 has been started. At this time, if the input current value is too large, it may damage the electronic components in the device to be started 2. When the input current value is greater than a preset current threshold, the current detection module 17 sends an interrupt signal to the processor 11. The processor 11 controls the control switch module 15 to disconnect according to the interrupt signal, so that the positive and negative electrical signals stop being applied to the positive terminal CAR+ and the negative terminal CAR-, thereby causing the device to be started 2 to stop working. It can be understood that the preset current threshold can be changed according to the current value that the device to be started 2 can bear.

[0035] In one possible embodiment, please refer to the following: Figure 6 , Figure 6This is a schematic diagram of a startup system framework provided in an embodiment of this application. The startup system 1 further includes a temperature detection module 18, which is electrically connected to the processor 11. When the startup system 1 is operating, the temperature detection module 18 detects the temperature values ​​of the electronic components in the startup system 1. When the temperature value exceeds a preset temperature threshold, the temperature detection module 18 sends an interrupt signal to the processor 11. The processor 11 controls the startup system 1 to stop operating based on the interrupt signal.

[0036] Specifically, in this embodiment, the startup system 1 further includes a control switch module 15. When the startup system 1 is working, that is, the device 2 to be started has been started. At this time, because current flows through the control switch module 15, the control switch module 15 will generate heat, which may damage the electronic components in the control switch module 15 if the working time increases. When the temperature value is greater than a preset temperature threshold, the temperature detection module 18 sends an interrupt signal to the processor 11. The processor 11 controls the control switch module 15 to disconnect according to the interrupt signal, so that the positive and negative electrical signals stop being applied to the positive electrode CAR+ and the negative electrode CAR-, thereby stopping the device 2 to be started from working. It can be understood that the preset temperature threshold can be changed according to the temperature value that the control switch module 15 can withstand.

[0037] In one possible embodiment, please refer to the following: Figure 7 , Figure 7 This is a schematic diagram of a startup system framework provided in an embodiment of this application. The startup system 1 further includes a short-circuit detection module 19, which is electrically connected to the processor 11. When the positive CAR+ and the negative CAR- are respectively connected to a positive electrical signal and a negative electrical signal, the short-circuit detection module 19 detects whether the positive CAR+ and the negative CAR- are short-circuited. If the positive CAR+ and the negative CAR- are short-circuited, the short-circuit detection module 19 sends a short-circuit electrical signal to the processor 11, causing the processor 11 to enter an abnormal alert state.

[0038] Specifically, the short-circuit detection module 19 can perform the detection after the device 2 to be started is started, or before the device 2 to be started is started. Specifically, in one possible embodiment, please refer to [the relevant documentation / reference]. Figure 8 , Figure 8This is a schematic diagram of a short-circuit detection module framework provided in an embodiment of this application. The short-circuit detection module 19 further includes a first short-circuit detection submodule 191, which detects whether the positive terminal CAR+ and the negative terminal CAR- are short-circuited before the positive terminal detection module 12 receives the positive terminal electrical signal or the reverse terminal detection module 13 receives the reverse terminal electrical signal.

[0039] In another possible embodiment, please refer again. Figure 8 The short circuit detection module 19 further includes a second short circuit detection submodule 192. When the startup system 1 is working, the second short circuit detection submodule 192 detects whether the positive electrode CAR+ and the negative electrode CAR- are short-circuited.

[0040] It is understandable that, in addition to detecting whether the positive CAR+ and negative CAR- are short-circuited via the hardware of the short-circuit detection module 19, they can also be detected via computer software. This application does not limit the method of detecting whether the positive CAR+ and negative CAR- are short-circuited.

[0041] In one possible embodiment, please refer to the following: Figure 9 , Figure 9 This is a schematic diagram of a startup system framework provided in an embodiment of this application. The startup system 1 further includes a communication module 1a, which stores a communication protocol. The communication module 1a interacts with a power supply device that provides positive and negative electrical signals according to the communication protocol, and determines whether the output capability of the power supply device meets the output conditions based on the positive and negative electrical signals.

[0042] Specifically, the communication protocols stored in the communication module 1a can be, but are not limited to, Controller Area Network (CAN) and Vehicle Area Network (VAN) protocols. The communication module 1a will establish communication with the power supply device by selecting one of the stored communication protocols. When the communication module 1a selects the same communication protocol as the power supply device, communication is successfully established. The communication module 1a then interacts with the devices providing positive and negative electrical signals according to the communication protocol.

[0043] Furthermore, in this embodiment, when the communication module 1a determines that the output capability of the power supply device meets the output conditions, the communication module 1a sends a data signal to the processor 11, so that the processor 11 controls the control switch module 15 to turn on according to the data signal, thereby loading the positive electrical signal and the negative electrical signal onto the positive electrode CAR+ and the negative electrode CAR-.

[0044] In one possible embodiment, please refer to the following: Figure 10 , Figure 10 This is a schematic diagram of a startup system framework provided in an embodiment of this application. The startup system 1 further includes a status display module 1b, which is used to display the working status of the startup system 1.

[0045] Specifically, the status display module 1b may include LED lights or a buzzer, etc. When the status display module 1b includes LED lights, different display colors of the LED lights represent different working states of the startup system 1. For example, when the processor 11 is in an abnormal alert state, the LED light is red; when the processor 11 is in a normal working state, the LED light is green. It is understood that the status display module 1b can display the status in other ways, and this application does not limit this. When the status display module 1b includes a buzzer, the working state of the startup system 1 is determined by whether the buzzer emits a sound. For example, when the processor 11 is in an abnormal alert state, the buzzer sounds; when the processor 11 is in a normal working state, the buzzer does not respond. It is understood that in this embodiment, the status display module 1b can display the status of the processor 11 more intuitively, thereby providing users with more intuitive information.

[0046] This application also provides a startup circuit 3, which is an embodiment applied to the startup system 1. Please refer to it accordingly. Figure 11 , Figure 11 This is a partial schematic diagram of a startup circuit provided in one embodiment of this application. Please refer to the diagram for the various electronic components in the startup circuit 3. Figure 11 .

[0047] It should be noted that, as Figure 11 As shown in the diagram, in this embodiment, the positive electrical signal is generated by the node labeled BAT+, and the negative electrical signal is generated by the node labeled BAT-. The negative terminal CAR- is grounded, meaning that the negative terminal CAR- is at the same potential as the ground wire. In the electrical connection relationship, if a grounded node appears, it is equivalent to that node being electrically connected to the negative terminal CAR-.

[0048] Furthermore, the positive polarity detection module 12 also includes a first resistor R26, a second resistor R27, and a third resistor R28. One end of the first resistor R26 is electrically connected to the positive terminal CAR+, and the other end of the first resistor R26 is electrically connected to the base of the first transistor 122 and one end of the second resistor R27. The other end of the second resistor R27 is electrically connected to the emitter of the first transistor 122. One end of the third resistor R28 is electrically connected to the processor 11, and the other end of the third resistor R28 is electrically connected to the collector of the first transistor 122. The positive polarity detection module 12 also includes a positive polarity diode D9, one end of which is electrically connected to the emitter of the first transistor 122, and the other end of which is grounded.

[0049] Understandably, due to the presence of the positive diode D9, current can only flow into the positive diode D9 from the emitter end of the first transistor 122. That is, when the positive terminal CAR+ receives the positive electrical signal and the negative terminal CAR- receives the negative electrical signal, the circuit in the positive detection module 12 is turned on, causing the first transistor 122 to send the positive electrical signal to the processor 11.

[0050] Specifically, the reverse connection detection module 13 further includes a fourth resistor R3, a fifth resistor R4, and a sixth resistor R18. One end of the fourth resistor R3 is grounded, and the other end of the fourth resistor R3 is electrically connected to the base of the second transistor 132 and one end of the fifth resistor R4. The other end of the fifth resistor R4 is electrically connected to the emitter of the second transistor 132. One end of the sixth resistor R18 is electrically connected to the processor 11, and the other end of the sixth resistor R18 is electrically connected to the collector of the first transistor 122. The reverse connection detection module also includes a reverse connection diode D1, one end of which is electrically connected to the emitter of the second transistor 132, and the other end of the positive connection diode D9 is electrically connected to the positive terminal CAR+.

[0051] Understandably, due to the presence of the reverse diode D1, current can only flow into the reverse diode D1 from the emitter end of the first transistor 122. That is, when the positive terminal CAR+ receives the negative electrical signal and the negative terminal CAR- receives the positive electrical signal, the circuit in the reverse detection module 13 is turned on, causing the second transistor 132 to send the reverse electrical signal to the processor 11.

[0052] This application also provides an electric vehicle; please refer to [link / reference]. Figure 12 , Figure 12This is a top view of the electric vehicle provided in this application. The electric vehicle 21 includes a battery 211, a positive terminal CAR+, a negative terminal CAR-, and a starting system 1 as described above. When the starting system 1 is working, the positive and negative electrical signals generated by the battery 211 are applied to the positive terminal CAR+ and the negative terminal CAR-, thereby starting the electric vehicle 21.

[0053] Specifically, the battery 211 serves as a power supply device to provide the positive and negative electrical signals. The starting system 1 is described above and will not be repeated here. When the starting system 1 is operational, that is, the positive electrical signal is applied to the positive terminal CAR+ via the control switch module 15 in the starting system 1, and the negative electrical signal is applied to the negative terminal CAR- via the control switch module 15, causing the electric vehicle 21 to start and begin operation.

[0054] Understandably, in this embodiment, the starting system 1 is highly reliable and safe, reducing the risk of problems that may occur when the electric vehicle 21 is working.

[0055] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
