Description

Technical Field

[0001] The present disclosure relates to the field of electronic technology, and in particular to a starting connection device, a starting power supply, and a starting method. Background Art

[0002] At present, with the promotion and popularization of automobile starting power supplies, various types of starting power supplies are available on the market. Starting power supplies can be used to start the car in an emergency. Starting power supplies have the advantages of portability, simplicity and high efficiency, and have been widely used.

[0003] However, the current starting power supplies on the market are not very intelligent. For example, when the car does not have a battery (storage battery), it cannot automatically identify the ignition and needs to be manually forced to output the ignition; or, when the starting power supply is connected to the car battery, it will automatically charge the battery, resulting in a significant reduction in the energy used to start the car. Therefore, how to improve the intelligence of the starting power supply has become an urgent problem to be solved. Summary of the invention

[0004] The embodiments of the present disclosure at least provide a starting connection device, a starting power supply and a starting method, which can solve at least one of the above problems.

[0005] The present disclosure provides a device for starting a connection, comprising:

[0006] A power connection terminal, used for electrically connecting to a power component;

[0007] A load connection terminal, used for electrically connecting to an external load;

[0008] A first switch circuit, electrically connected between the power connection terminal and the load connection terminal;

[0009] a controller, electrically connected to the first switch circuit, wherein the first switch circuit enters a conducting state upon receiving a driving signal output by the controller;

[0010] A voltage source module, configured to output a first voltage;

[0011] a second switch circuit, electrically connected between the voltage source module and the load connection terminal, and receiving a first control signal output by the controller, wherein the first control signal is used to control the second switch circuit to be alternately turned on and off;

[0012] A voltage detection module, electrically connected to the load output terminal, for respectively detecting the voltage of the load connection terminal when the second switch circuit is alternately turned on and off;

[0013] The controller is also electrically connected to the voltage detection module, and is used to identify whether the load connection terminal is connected to a load and the type of the connected load based on the voltage detected by the voltage detection module, and when it is determined that the load connection terminal is connected to the load, control the start connection device to enter a start mode corresponding to the load type.

[0014] In the embodiment of the present disclosure, by detecting the voltage at the load connection terminal, it is automatically identified whether the load connection terminal is connected to a load, and the starting connection device can be controlled to enter a starting mode corresponding to the load type according to the type of load, thereby being able to intelligently supply power to the load, which is beneficial to improving the use efficiency of the starting connection device.

[0015] In some embodiments, if the voltage detection module detects that the voltage at the load connection end is greater than a first preset voltage value while the second switch circuit is in an off state, the controller determines that the load connection end is connected to a power supply type load and controls the startup connection device to enter a first startup mode.

[0016] In the embodiment of the present disclosure, whether the power supply load is connected is determined by detecting whether the voltage at the load connection terminal is greater than a first preset voltage value when the second switch circuit is in the disconnected state, that is, when the load connection terminal is in a low voltage state. This can improve the accuracy of determining whether the load is a power supply type load.

[0017] In some embodiments, if the voltage detection module detects that the voltage at the load connection end is between the second preset voltage value and the third preset voltage value while the second switch circuit is in the on state, the controller determines that the load connection end is connected to a power-consuming type load and controls the startup connection device to enter the second startup mode.

[0018] In the embodiment of the present disclosure, whether a power-consuming load is connected is determined by detecting whether the voltage at the load connection terminal is between the second preset voltage value and the third preset voltage value while the second switch circuit is in the on state, that is, the load connection terminal is in a high voltage state. This can improve the accuracy of determining whether the load is a power-consuming type load.

[0019] In some embodiments, the startup connection device further includes a current detection module; the current detection module is electrically connected between the power connection terminal and the load connection terminal, and is used to detect the current state of the output circuit; the controller is also electrically connected to the current detection module;

[0020] In the first startup mode, the controller stops outputting the first control signal so that the second switch circuit is in an off state, and outputs the driving signal to control the first switch circuit to be in an on state for a first preset time;

[0021] The controller is further configured to control the first switch circuit to be continuously turned on or off according to the current state of the output circuit detected by the current detection module within the first preset time.

[0022] In the embodiment of the present disclosure, the controller outputs the driving signal to control the first switch circuit to be in the on state and last for the first preset time, so as to avoid the power supply component electrically connected to the power connection terminal from continuously supplying power to the load. In addition, the first switch circuit is controlled to be continuously on or off according to the current state of the output circuit detected within the first preset time, and then the on and off of the first switch circuit can be controlled according to the working state of the power supply type load, which is conducive to maximizing the utilization of energy.

[0023] In some embodiments, if within the first preset time, the current detection module detects that the output current of the output circuit is greater than the first preset current value, the controller continues to output the drive signal to control the first switch circuit to remain in the on state for a second preset time; or,

[0024] If within the first preset time, the current detection module detects that the output current of the output circuit is not greater than the first preset current value, the controller stops outputting the drive signal after the first preset time to control the first switch circuit to be in an off state and last for a third preset time.

[0025] In an embodiment of the present disclosure, if within the first preset time, the current detection module detects that the output current of the output circuit is greater than the first preset current value, it means that the power supply type load is in a working state. At this time, the car needs to be started, and then the first switch circuit needs to be controlled to remain in an on state and last for a second preset time to complete the starting of the car; if within the first preset time, the current detection module detects that the output current of the output circuit is not greater than the first preset current value, it means that the power supply type load is not working at this time, that is, the car is not started at this time. Therefore, in order to avoid energy waste, the first switch circuit needs to be controlled to be in an off state and last for a third preset time.

[0026] In some embodiments, within the third preset time, if the voltage detection module detects that the voltage at the load connection terminal is less than a fourth preset voltage value, the controller controls the startup connection device to exit the first startup mode.

[0027] In the disclosed embodiment, within the third preset time, if the voltage detection module detects that the voltage at the load connection terminal is less than a fourth preset voltage value, it indicates that the power supply load is disconnected from the load connection terminal, that is, there is no need to start the car at this time, and the first mode can be exited to avoid wasting system resources.

[0028] In some embodiments, in the second start-up mode, the controller stops outputting the first control signal so that the second switch circuit is in an off state; the controller also outputs the drive signal to control the first switch circuit to be in an on state, and after the duration of the on state of the first switch circuit reaches a fourth preset time, the controller stops outputting the drive signal and controls the start-up connection device to exit the second start-up mode.

[0029] In the disclosed embodiment, after the duration of the on-state of the first switch circuit reaches a fourth preset time, the drive signal is stopped from being output, and the starting connection device is controlled to exit the second starting mode. That is, after the vehicle completes ignition, the second starting mode can be exited, thereby avoiding energy waste and helping to improve the use efficiency of the starting connection device.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. The components of the embodiments of the present disclosure generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the drawings is not intended to limit the scope of the present disclosure for protection, but merely represents the selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present disclosure.

[0080] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0081] The term "and / or" herein only describes an association relationship, indicating that three relationships may exist. For example, A and / or B may represent the following three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the term "at least one" herein represents any combination of at least two of any one or more of a plurality of. For example, including at least one of A, B, and C may represent including any one or more elements selected from the set consisting of A, B, and C.

[0082] At present, with the promotion and popularization of automobile starting power supplies, various types of starting power supplies are available on the market. Starting power supplies can be used to start the car in an emergency. Starting power supplies are often used in large quantities due to their advantages such as portability, simplicity and high efficiency.

[0083] However, the current starting power supplies on the market are not very intelligent. For example, when the car does not have a battery (storage battery), it cannot automatically identify the ignition and needs to be manually forced to output the ignition; or, when the starting power supply is connected to the car battery, it will automatically charge the battery, resulting in a significant reduction in the energy used to start the car. Therefore, how to improve the intelligence of the starting power supply has become an urgent problem to be solved.

[0084] Based on the above research, an embodiment of the present disclosure provides a startup connection device, including: a power connection terminal, a load connection terminal, a first switch circuit, a controller, a voltage source module, a second switch circuit and a voltage detection module. The first switch circuit is electrically connected between the power connection terminal and the load connection terminal. The second switch circuit is electrically connected between the voltage source module and the load connection terminal, and receives a first control signal output by the controller. The voltage detection module is electrically connected to the load output terminal, and is used to respectively detect the voltage of the load connection terminal when the second switch circuit is alternately turned on and off. When the controller determines that the load connection terminal is connected to the load, it controls the startup connection device to enter a startup mode corresponding to the load type.

[0085] The starting connection device provided in the embodiment of the present disclosure can not only identify whether the load connection terminal is connected to a load, but also identify the type of load connected to the load connection terminal, and control the starting connection device to enter a corresponding starting mode according to the load type, without the user having to perform other operations, thereby realizing intelligent car starting.

[0086] See also Figure 1 , Figure 1 This is a functional module diagram of a startup connection device provided by an embodiment of the present disclosure. Figure 1 As shown, a startup connection device 100 provided in an embodiment of the present disclosure includes a power connection terminal 10, a load connection terminal 20, and a first switch circuit 30. The power connection terminal 10 is used to be electrically connected to a power supply component (not shown in the figure), the load connection terminal 20 is used to be electrically connected to an external load (not shown in the figure), and the first switch circuit 30 is electrically connected between the power connection terminal 10 and the load connection terminal 20.

[0087] The power supply component may be any one of a DC power supply, a battery pack or a supercapacitor, which is not limited here.

[0088] The power connection terminal 10, the load connection terminal 20 and the first switch circuit 30 constitute a current output loop 11 for the power supply component to supply power to the external load, and the first switch circuit 30 is used to turn on or off the current output loop 11. In this way, the power supply component can supply power to the external load through the start connection device 100.

[0089] In the embodiment of the present disclosure, the power connection terminal 10 includes a positive power connection terminal BAT+ and a negative power connection terminal BAT-, wherein the positive power connection terminal BAT+ and the negative power connection terminal BAT- are used to be electrically connected to the positive and negative electrodes of the power component in a one-to-one correspondence. The power component is connected to the start connection device 100 through the power connection terminal 10, thereby providing a working voltage for the start connection device 100, and supplying power to the external load through the first switch circuit 30.

[0090] The load connection terminal 20 includes a load positive connection terminal CAR+ and a load negative connection terminal CAR-, wherein the load positive connection terminal CAR+ and the load negative connection terminal CAR- are used to be electrically connected to the positive and negative electrodes of the external load in a one-to-one correspondence, and the load negative connection terminal CAR- is also electrically connected to the first ground terminal. The external load may be a car battery or a car starter. It is understood that the car battery includes but is not limited to a lead-acid battery, a lithium iron phosphate battery, a supercapacitor, etc.

[0091] For example, see Figure 2 , Figure 2 This is a functional module diagram of a startup connection device to supply power to a car provided by an embodiment of the present disclosure. Figure 2 As shown in , the external power source 600 can start the car 900 in an emergency through the starting connection device 100. It can be understood that, under normal circumstances, the car battery 300 is connected to the car starter 400 for starting the car 900. When the car battery 300 is low on power, the connection between the car battery 300 and the car starter 400 can be disconnected, the starting connection device 100 can be connected to the car starter 400, and then the vehicle can be started to make the car engine 500 work; or the car battery 300 and the starting connection device 100 are connected in parallel, and then connected to the car starter 400, and then the car 900 is started. That is, when the car battery 300 is disconnected from the car starter 400, the external load is the car starter; when the car battery 300 is not disconnected from the car starter 400, the external load is the car battery.

[0092] Please refer again Figure 1 The startup connection device also includes a controller 40, a voltage source module 50, a second switch circuit 60 and a voltage detection module 70.

[0093] The controller 40 is electrically connected to the first switch circuit 30, wherein the first switch circuit 30 enters a conducting state upon receiving a driving signal output by the controller 40. The voltage source module 50 is configured to output a first voltage. For example, the first voltage may be 3V or 5V, which is not limited here.

[0094] The second switch circuit 70 is electrically connected between the voltage source module 50 and the load connection terminal 20, and receives a first control signal output by the controller 40, wherein the first control signal is used to control the second switch circuit 60 to be alternately turned on and off.

[0095] In some embodiments, the first control signal is composed of alternating high level signals and low level signals. For example, the first control signal may be a pulse width modulation signal (PWM), wherein the PWM signal includes a plurality of pulse signals with equal amplitudes but different widths.

[0096] The voltage detection module 70 is electrically connected to the load output terminal 20, and is used to detect the voltage of the load connection terminal 20 when the second switch circuit 60 is alternately turned on and off. The controller 40 is also electrically connected to the voltage detection module 70, and is used to identify whether the load connection terminal 20 is connected to an external load and the type of the connected external load based on the voltage detected by the voltage detection module 70, and when it is determined that the load connection terminal 20 is connected to the external load, control the start-up connection device 100 to enter a start-up mode corresponding to the external load type.

[0097] When the positive connection terminal and the negative connection terminal of the load connection terminal 20 are not connected to the car battery or the car engine, the controller 40 controls the second switch circuit 60 to be turned on or off by outputting the first control signal, and then controls the voltage source module 50 to intermittently output the first voltage, that is, the voltage source module 50 can periodically output the first voltage to the load connection terminal 20, wherein the time to start the output voltage and the time to disconnect the output voltage can be set according to actual conditions, that is, the duration of the high-level signal and the low-level signal of the first control signal can be adjusted according to specific needs, for example, it can be achieved by adjusting the duty cycle of the PWM signal.

[0098] If, during the period when the voltage source module 50 starts to output voltage, the voltage detection module 70 detects that the voltage value of the load connection terminal 20 is the same as the voltage value of the voltage source module, it is considered that the load connection terminal 20 is not connected to the car battery 300 or the car starter 400 at this time; if, during the period when the voltage source module 50 turns off the output voltage, the voltage detection module 70 detects that the voltage value of the load connection terminal 20 has not changed, it is also considered that the load connection terminal 20 is not connected to the car battery 300 or the car starter 400 at this time, and then continues to control the voltage source module 50 to periodically output voltage.

[0099] In some embodiments, if the voltage detection module 70 detects that the voltage of the load connection terminal 20 is greater than the first preset voltage value during the period when the second switch circuit 60 is in the disconnected state, the controller 40 determines that the load connection terminal 20 is connected to a power supply type load, and the controller 40 controls the start connection device 100 to enter the first start mode. The power supply type load refers to a power supply type load that can provide energy. In the embodiment of the present disclosure, the power supply type load is a car battery 300.

[0100] The first preset voltage value may be set according to the model and specification of the load product connected to the load connection terminal 20 . For example, the first preset voltage value may be 0.6V, which is not limited here.

[0101] It can be understood that since the voltage value of the load connection terminal 20 is approximately 0V when the second switch circuit 60 is in the disconnected state, if the voltage detection module 70 detects that the voltage value of the load connection terminal 20 is greater than the first preset voltage value during this period, it means that the load connection terminal 20 is connected to a power supply type load.

[0102] It should be noted that the 0V described in the embodiment of the present disclosure represents the voltage value of the load connection terminal 20 when the second switch circuit 60 is in a disconnected state and the load connection terminal 20 is in a no-load state. However, in actual situations, the voltage value of the load connection terminal 20 may be 0V or a very small value.

[0103] In some embodiments, if the voltage detection module 70 detects that the voltage of the load connection terminal 20 is between the second preset voltage value and the third preset voltage value during the period when the second switch circuit 60 is in the on state, the controller 40 determines that the load connection terminal 20 is connected to a power-consuming load, and controls the start-up connection device 100 to enter the second start-up mode. The power-consuming load refers to a load that consumes electrical energy. In the embodiment of the present disclosure, the power-consuming load may be a car starter 400.

[0104] Among them, the third preset voltage value is the voltage value when the load connection end is in a no-load state, that is, the voltage value of the voltage source. The second preset voltage value can be 0.5V. It should be noted that if the second preset voltage value is set too small, a short circuit or overcurrent in the load may be mistaken for being normal. Therefore, when setting it, care should be taken to avoid setting its value too small.

[0105] It can be understood that, since the voltage value of the load connection terminal 20 is the voltage value of the voltage source module 50 during the period when the second switching circuit 60 is in the on state, if it is detected during this period that the voltage of the load connection terminal 20 is greater than the second preset voltage value and less than the voltage value of the voltage source module 50, it means that the external load connected to the load connection terminal 20 at this time shares part of the voltage, that is, the external load is a power-consuming type load.

[0106] In this embodiment, whether a power supply type load is connected is determined by detecting whether the voltage of the load connection terminal 20 is greater than the first preset voltage value when the second switch circuit 60 is in the off state, and whether a power consumption type load is connected is determined by detecting whether the voltage of the load connection terminal 20 is between the second preset voltage value and the third preset voltage value when the second switch circuit 60 is in the on state, thereby improving the accuracy of determining the external load type.

[0107] See also Figure 3 , Figure 3 Schematic diagram of functional modules of another start-up connection device provided by an embodiment of the present disclosure. In some embodiments, the start-up connection device 100 further includes a current detection module 90. The current detection module 90 is electrically connected between the power supply negative connection terminal BAT- and the load negative connection terminal CAR-, and is used to detect the current state of the output loop 11, and is connected to the controller 40.

[0108] In the embodiment of the present disclosure, in the first start-up mode, the controller 40 stops outputting the first control signal so that the second switch circuit 60 is in an off state. At this time, the controller 40 outputs the drive signal to control the first switch circuit 30 to be in an on state and lasts for a first preset time, wherein the first preset time can be manually set according to actual conditions.

[0109] The controller 40 controls the first switch circuit 30 to be continuously turned on or off according to the current state of the output circuit 11 detected by the current detection module 90 within the first preset time.

[0110] For example, Figure 3As shown in , the current detection module 90 is electrically connected to the output circuit 11, and is used to detect the output current of the output circuit 11. If the output current is greater than the first preset current value, it means that the automobile starter 400 is in a working state, and the controller 40 needs to continuously output the driving signal to control the first switch circuit 30 to remain in a conductive state for a second preset time, so that the automobile 900 completes the start. Among them, the second preset time is related to the time required for the automobile to start, and can be specifically set according to different types of automobiles.

[0111] If the current detection module 90 detects that the output current of the output circuit 11 is not greater than the first preset current value within the first preset time, it means that the car starter is not in a working state, that is, the car is not started at this time, then after the first preset time, the controller 40 stops outputting the driving signal to control the first switch circuit 30 to be in an off state and last for a third preset time. In this way, it can be avoided that the power supply component continues to discharge when the starter is not working.

[0112] Exemplarily, the first preset current value can be set according to actual conditions, such as 0.5A, 1A, etc., which is not limited here. The second preset time can be set in advance, such as 5 seconds, 10 seconds, etc., which is not limited here. The third preset time can be set manually, such as 5 seconds, 10 seconds, etc., which is not limited here. Among them, the first preset time, the second preset time and the third preset time can be the same or different, which is not specifically limited here.

[0113] It can be understood that if the output current is not greater than the first preset current value within the first preset time, it means that although the load connection terminal 20 is connected to the automobile battery 300, the automobile starter 400 is not started at this time, so the first switch circuit 30 is controlled to be in an off state. However, since it may be necessary to start the automobile during the period when the first switch circuit 30 is in an off state, the first switch circuit 30 is in an off state and only needs to last for a third preset time. That is, after the first switch circuit 30 is in an off state for the third preset time, the controller 40 outputs a drive signal to control the first switch circuit 30 to be in an on state and last for the first preset time. This reciprocating process can not only disconnect the output circuit when the automobile is not started, but also control the output circuit to be closed when the automobile is started, so as to start the automobile in an emergency.

[0114] In some embodiments, if the output current of the output circuit is detected to be greater than the second preset current value within the first preset time, it means that the output circuit has an overcurrent condition, and the first switch circuit needs to be disconnected to stop supplying power to the load, thereby ensuring power supply safety. Wherein, the second preset current value is greater than the first preset current value.

[0115] It can be understood that if the output current of the output circuit is detected to be greater than the second preset current value within the first preset time, it means that the output circuit is short-circuited. In order to avoid safety risks caused by short circuit of the starting connection device, the first switch circuit 30 should be disconnected.

[0116] In some embodiments, within the third preset time, if the voltage detection module 90 detects that the voltage of the load connection terminal 20 is less than a fourth preset voltage value, it means that the vehicle battery is disconnected from the starting connection device 100, that is, the starting connection device 100 has been removed from the vehicle. At this time, the controller 40 controls the starting connection device 100 to exit the first starting mode and return to the initial detection state.

[0117] The fourth preset voltage value is smaller than the first preset voltage value. For example, when the first preset voltage value is 0.6V, the fourth preset voltage value may be 0.4V.

[0118] In some embodiments, in the second start-up mode, the controller 40 stops outputting the first control signal so that the second switch circuit 60 is in the disconnected state, that is, the voltage source module 50 is controlled to stop outputting voltage. The controller 40 also outputs the drive signal to control the first switch circuit 30 to be in the on state, and controls the duration of the on state of the first switch circuit 30 to be a fourth preset time, wherein the fourth preset time is set because it is necessary to reserve the start time for starting the car engine. In addition, the fourth preset time can be set according to actual conditions. For example, for different cars, the start time may be different, so it can be set according to different brands of cars. After the duration of the on state of the first switch circuit 30 is the fourth preset time, the drive signal is stopped from being output, that is, the first switch circuit 30 is controlled to be disconnected, and then the output circuit 11 is controlled to be disconnected, and the start connection device is controlled to exit the second start-up mode.

[0119] The fourth preset time may be set in advance, such as 5 seconds, 10 seconds, etc., which is not limited here.

The first connection end of the first voltage dividing unit 71 is electrically connected to the load positive connection end CAR+, the second connection end of the first voltage dividing unit 71 is electrically connected to the fifth pin 5 of the controller 40, the second connection end of the first voltage dividing unit 71 is also electrically connected to the first connection end of the second voltage dividing unit 72, and the second connection end of the second voltage dividing unit 72 is grounded.

[0141] In some embodiments, the voltage detection module 70 further includes a third capacitor C3, and the first connection end and the second connection end of the third capacitor C3 are respectively connected to the first connection end and the second connection end of the second voltage divider unit 72, that is, the third capacitor C3 is connected in parallel with the second voltage divider unit 72.

[0144] In some embodiments, the controller 40 can be any type of programmable logic controller (PLC), such as a microcontroller unit (MCU), a field-programmable gate array (FPGA), or a digital signal processor (DSP), etc., which are not limited here. The controller 40 serves as the logic operation and control center of the startup connection device 100, and is mainly responsible for functions such as data acquisition and conversion, logic operation, data communication, and execution drive output.

[0145] The working principle of the start-up connection device 100 is described below.

[0146] Please refer again Figure 6 ,like Figure 6 As shown in the figure, during the operation of the starting connection device 100, the power supply component inputs voltage to the power conversion module 80 through the power connection terminal 10, and the first voltage VCC output by the power conversion module 80 (that is, the output voltage of the voltage source module 50) is used to supply power to each module of the starting device 100.

[0147] During the period when the load connection terminal 20 is in the no-load state, the controller 40 outputs the first control signal through the third pin 3 to control the second driving module 62 to be periodically turned on and off. Specifically, when the first control signal is a high-level signal, the NPN-type digital transistor Q3 is turned on. Since the emitter of the NPN-type digital transistor Q3 is grounded, when it is turned on, the gate of the P-type MOS field effect transistor Q2 in the second electronic switch 61 is a low voltage. In this way, the P-type MOS field effect transistor Q2 is turned on, and then the voltage source module 50 can output the first voltage VCC to the load connection terminal, so that the load connection terminal 20 is in a high voltage state; when the first control signal is a low-level signal, the digital transistor Q3 is in a disconnected state, and the P-type MOS field effect transistor Q2 is also in a disconnected state. At this time, the load connection terminal 20 does not receive the first voltage and is in a low voltage state.

[0148] In this way, if during the period when the voltage source module 50 is disconnected from output, if the 5th pin of the controller 40 detects that the voltage of the load connection terminal 20 is greater than the first preset voltage value, it means that the load connection terminal 20 is connected to a power supply type load (i.e., a car battery). At this time, the controller 40 controls the starting connection device 100 to enter the first starting mode.

[0149] In the first startup mode, the controller 40 outputs the driving signal (high level signal) to the first driving module 32 through the first pin 1. Since the first transistor Q1 in the first driving module 32 is an N-type MOS field effect transistor, the control end of the first transistor Q1 is at a high level, the first transistor Q1 is turned on, and the voltage of the second connection end of the first resistor R1 is 0V. At the same time, the level of the fourth connection end 4 of the relay K1 in the first electronic switch 31 is low, and the level of the third connection end 3 of the relay K1 is high. Then, current passes through the coil in the relay K1, and the coil generates a magnetic field to attract the single-pole single-throw switch to close, thereby turning on the output circuit 11 and lasting for a first preset time.

[0150] The current detection module 90 detects the current signal in the output circuit 11. When the controller 40 detects through the second pin 2 that the current in the output circuit 11 is greater than the first preset current value, the controller 40 continues to output the drive signal to turn on the output circuit 11 and lasts for the second preset time; when the controller 40 detects that the current in the output circuit 11 is not greater than the first preset current value, then after the first preset time is reached, the controller 40 stops outputting the drive signal, so that the first switch circuit 30 is in the disconnected state and lasts for the third preset time, that is, the output circuit 11 is in the disconnected state.

[0151] During the third preset time when the first switch circuit 30 is in the disconnected state, if the 5th pin of the controller 40 detects that the voltage of the load connection terminal 20 is less than the fourth preset voltage value, it means that the vehicle battery is disconnected from the load connection terminal 20. At this time, the controller 40 controls the starting connection device 100 to exit the first starting mode.

[0152] If, during the period when the voltage source module 50 is turned on for output, the 5th pin of the controller 40 detects that the voltage value of the load connection terminal 20 is between the second preset voltage value and the third preset voltage value (that is, the voltage value is greater than the second preset voltage value and less than the first voltage VCC), it means that the load connection terminal 20 is connected to a power-consuming load (that is, a car starter), and at this time, the controller 40 controls the starting connection device 100 to enter the second starting mode.

[0153] In the second startup mode, the controller 40 outputs the drive signal through the first pin 1, that is, the controller 40 controls the output circuit 11 to be in the on state and lasts for a fourth preset time; after the fourth preset time, the controller 40 stops outputting the drive signal, that is, controls the output circuit 11 to be in the off state, and controls the startup connection device 100 to exit the second startup mode.

[0154] In this embodiment, the specific circuits of the above-mentioned units are not limited, as long as each unit can realize the corresponding functions. In addition, each unit can be integrated on the same circuit substrate and arranged in the same housing, or integrated on different circuit substrates and arranged in different housings. The specific combination can be carried out according to the actual situation, and no specific limitation is made here.

Figure 7 As shown in FIG. 1 , the starting power supply 200 includes a power supply component 110 and a partial module structure of the starting connection device 100 described above, wherein the module of the starting connection device 100 is Figure 7 The power supply assembly 110 is electrically connected to the power supply connection terminal 10, specifically, the positive electrode of the power supply assembly 110 is electrically connected to the positive power connection terminal BAT+ of the power supply connection terminal 10, and the negative electrode of the power supply assembly 110 is electrically connected to the negative connection terminal BAT- of the power supply connection terminal 10.

[0156] The present disclosure also provides a startup method, which is applied to the startup connection device 100. Figure 8 , Figure 8 A flowchart of a startup method provided by an embodiment of the present disclosure is shown in FIG. Figure 8As shown, a startup method provided by an embodiment of the present disclosure includes the following S601-S602:

[0157] S601 , identifying whether the load connection terminal is connected to a load and the type of the connected load based on the detected voltage of the load connection terminal when the second switch circuit is alternately turned on and off.

[0158] S602: When it is determined that the load connection terminal is connected to the load, control the start-up connection device to enter a start-up mode corresponding to the load type.

[0159] In some implementations, for the above steps S601-S602, see Fig. 9 , Fig. 9 A flowchart of another startup method provided by an embodiment of the present disclosure, such as Fig. 9 As shown, a startup method provided by an embodiment of the present disclosure includes the following S701 to S709:

[0160] S701, detecting the voltage of the load connection terminal when the second switch circuit is alternately turned on and off.

[0161] S702, while the second switch circuit is in the off state, detect whether the voltage at the load connection end is greater than a first preset voltage value; if so, execute step S703, if not, execute step S701.

[0162] Since the voltage at the load connection terminal is 0V or close to 0V when the second circuit is in the disconnected state, whether the load type connected to the load connection terminal is a power supply type load is determined by detecting whether the voltage at the load connection terminal is greater than the first preset voltage value.

[0163] S703, controlling the startup connection device to enter a first startup mode.

[0164] If it is detected that the load type of the load connection end is a power supply type load, the startup connection device is controlled to enter the first startup mode, that is, the startup mode corresponding to the power supply type load is the first startup mode.

[0165] S704, controlling the second switch circuit to be in an off state, and controlling the first switch circuit to be in an on state and lasting for the first preset time.

[0166] S705, determining whether the current of the output circuit is greater than a first preset current value within the first preset time; if so, executing step S706, if not, executing step S707.

[0167] By detecting whether the current of the output circuit is greater than a first preset current value, it is used to determine whether the vehicle starter is in a working state.

[0168] S706, controlling the first switch circuit to remain in an on state for a second preset time.

[0169] When the current of the output circuit is greater than the first preset current value, it indicates that the vehicle starter is in working state, and the vehicle engine is started by controlling the first switch circuit to remain in the on state for a second preset time.

[0170] S707: After the first preset time, control the first switch circuit to be in an off state and keep it in an off state for a third preset time.

[0171] When the current of the output circuit is less than the first preset current value, it means that the car starter is not in working state. Then, after the first preset time, the first switch circuit is controlled to be in the disconnected state and lasts for a third preset time to avoid continuous discharge of the power supply component.

[0172] S708, determining whether the voltage of the load connection terminal is less than a fourth preset voltage value within the third preset time; if so, executing step S709, if not, executing step S704.

[0173] S709, controlling the startup connection device to exit the first startup mode; and executing step S701.

[0174] In some implementations, for the above steps S601-S602, see Fig.10 , Fig.10 A flowchart of another startup method provided by an embodiment of the present disclosure is shown in FIG. Fig.10 As shown, another startup method provided by the embodiment of the present disclosure includes the following S801 to S805:

[0175] S801, detecting the voltage of the load connection terminal when the second switch circuit is alternately turned on and off.

[0176] S802, determining whether the voltage at the load connection terminal is between the second preset voltage value and the third preset voltage value while the second switch circuit is in the on state; if so, executing step S803, if not, executing step S801.

[0177] Since when the second circuit is in the on state, the voltage at the load connection end is the output voltage of the voltage source module or is close to the output voltage of the voltage source module, it is possible to determine whether the load type connected to the load connection end is a power-consuming type load by detecting whether the voltage at the load connection end is between the second preset voltage value and the third preset voltage value.

[0178] S803, controlling the startup connection device to enter a second startup mode.

[0179] When the voltage at the load connection terminal is between the second preset voltage value and the third preset voltage value, the startup connection device is controlled to enter the second startup mode, that is, the startup mode corresponding to the power consumption type load is the second startup mode.

[0180] S804, controlling the second switch circuit to be in an off state.

[0181] Since the second startup mode has been entered, there is no need to detect the voltage of the load connection terminal, and the second switch circuit can be controlled to be in a disconnected state.

[0182] S805, controlling the first switch circuit to be in a conducting state, and after the duration of the conducting state of the first switch circuit reaches a fourth preset time, controlling the start-up connection device to exit the second start-up mode; and executing step S801.

[0183] In the second start mode, the controller outputs a driving signal to put the first switch circuit in an on state and maintain it for a fourth preset time. The fourth preset time is a reserved time for starting the car. The car can be started within the fourth preset time. If the car is not started during this period, then after the fourth preset time is reached, the start connection device is controlled to exit the second start mode, and after exiting the second start mode, the start connection device continues to execute step S801 to achieve the purpose of intelligently starting the car.
