CONCRETE IMPLEMENTATION

[0040] In order to make the technical problem solved by the utility model, the technical scheme and the beneficial effect more clearly, the following will be further detailed in the embodiment, the utility model is explained in detail.The specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0041] The specific embodiments are combined Figures 1 to 8As shown, further illustrate the technical scheme of the utility model, a start control circuit, including battery 100, detection module 200, main control module 300 and starting module 400, the battery 100 is used to provide starting power supply for vehicle, the detection signal input end of detection module 200 is connected with the power output end of battery 100, the detection module 200 is used to detect the state of charge of battery 100, the control signal input end of main control module 300 is connected with the detection signal output end of detection module 200, main control module 300 is used to export soft start control signal or emergency start control signal according to the state of charge of battery 100, the start control input end of starting module 400 is connected with the control signal output end of main control module 300, the start control output end of starting module 400 is used to execute soft start operation according to the soft start control signal, or is used to execute emergency start operation according to the emergency start control signal.

[0042] Specifically, the control signal output end of the main control module 300 includes a first control signal output end (i.e. the PWM1 end of the embodiment) and a second control signal output end (i.e. the PWM2 end of the embodiment), when the battery 100 has normal power, the first control signal end of the main control module 300 outputs a soft start control signal, and when the battery 100 is insufficient, the second control signal output end of the main control module 300 outputs an emergency start control signal.

[0043] The start control circuit provided in the application can adopt corresponding starting strategies according to the state of charge of the battery, ensure that the vehicle can be started smoothly in various situations, and improve the user experience; and when the battery has sufficient power, the vehicle is started in a soft start mode, which reduces the large current impact during starting compared with the traditional starting mode, protects the starting motor and reduces the loss of the battery.

[0044] Further, as a preferred embodiment of the present scheme but not limited, the detection module 200 includes a resistor R12 and a resistor R13, the power output end of the battery 100 (i.e. the VIN end of the embodiment) is connected with one end of the resistor R12, the other end of the resistor R12 is connected with one end of the resistor R13, and the other end of the resistor R13 is connected with the control signal input end (i.e. the BTV end of the embodiment) of the main control module 300.

[0045] In the embodiment, the master module compares the voltage value at the BTV terminal after being divided by the resistors R12 and R13 with a preset voltage value. Once the voltage value is lower than the preset voltage value, it is determined that the battery is insufficient. Meanwhile, the voltage output by the battery is reduced to a voltage range suitable for the master module by the voltage dividing circuit composed of the resistors R12 and R13, so that the master module can detect the state of the battery and protect the master module, and ensure the normal operation of the starting control circuit.

[0046] Further, as a preferred embodiment of the present scheme, the starting module 400 comprises a soft starting unit 410 and an emergency starting unit 420. The power input terminal of the soft starting unit 410 is connected with the power output terminal of the battery 100. The starting control input terminal of the soft starting unit 410 is connected with the first control signal output terminal of the master module 300. The soft starting unit 410 is used to perform soft starting operation according to the soft starting control signal. The starting control input terminal of the emergency starting unit 420 is connected with the second control signal output terminal of the master module 300. The starting control output terminal of the emergency starting unit 420 is connected with the battery. The emergency starting unit 420 is used to perform emergency starting operation according to the emergency starting control signal.

[0047] In the embodiment, through the cooperative work of the soft starting unit and the emergency starting unit, the starting module can effectively reduce the starting large current impact, protect the battery and mechanical parts, not only prolong the life of the battery and the starting motor, but also ensure the smooth starting of the vehicle in various situations, improve the starting reliability, and improve the user experience.

[0048] As a preferred embodiment, the soft starting unit 410 comprises a control subunit 411 and a starting subunit 412. The control input terminal of the control subunit 410 is connected with the first control signal output terminal of the master module 300. The control subunit 410 is used to control the starting subunit 412 to provide soft starting for the vehicle. The control output terminal of the control subunit 411 is connected with the input terminal of the starting subunit 412. The output terminal of the starting subunit 412 is used to soft start the vehicle.

[0049] Alternatively, the control subunit 411 includes a first switching transistor Q1, a resistor R1, and a resistor R2. The first control signal output terminal of the main control module 300 is connected to one end of the resistor R2, the other end of the resistor R2 is connected to the controlled terminal of the first switching transistor Q1, the power output terminal of the battery 100 is connected to one end of the resistor R1, the other end of the resistor R1 is connected to the first conducting terminal (i.e., the source) of the first switching transistor Q1, and the second conducting terminal (i.e., the drain) of the first switching transistor Q1 is connected to the input terminal of the start-up subunit 412.

[0050] Alternatively, the startup subunit 412 includes a second switch Q2, a third switch Q3, resistors R4, R5, R6, and R7, and a capacitor C3. The control output terminal of the control subunit 411 is connected to the first conducting terminal (i.e., emitter) of the second switch Q2. The control output terminal of the control subunit 411 is also connected to one end of the resistor R4. The other end of the resistor R4 is connected to the controlled terminal (i.e., base) of the second switch Q2. The second conducting terminal (i.e., collector) of the second switch Q2 is connected to ground. The resistor R5 is connected in series. The second conducting terminal of the second switch Q2 is also connected to one end of the resistor R6. The other end of the resistor R6 is connected to the controlled terminal (i.e., gate) of the third switch Q3. The control output terminal of the control subunit 411 is also connected to the first conducting terminal (i.e., source) of the third switch Q3. The capacitor C3 and the resistor R7 are connected in series between the controlled terminal and the second conducting terminal (i.e., drain) of the third switch. The second conducting terminal of the third switch is used to provide soft start for the vehicle.

[0051] Specifically, when the main control module 300 detects that the battery 100 has sufficient power, the first control signal output terminal of the main control module 300 will output a soft start control signal. After receiving the first control signal, the controlled terminal of the first switch Q1 will turn on. At this time, the base of the second switch Q2 will also turn on after receiving the electrical signal. The collector voltage of the second switch Q2 will slowly increase as the base voltage increases. As a result, the gate voltage of the third switch Q3 will slowly increase as the collector voltage of the second switch Q2 increases. Its output current will also gradually increase, ultimately achieving a soft start for the vehicle and avoiding the impact of instantaneous large current on the battery and mechanical components, thus improving the smoothness and reliability of the start-up.

[0052] In this embodiment, a soft-start method is adopted. By gradually increasing the current, the mechanical impact during startup can be reduced, thereby reducing vibration and noise during startup and ensuring a smooth vehicle startup process. At the same time, through the coordinated control between the switching transistors, the current rise rate can be more precisely controlled to ensure a smooth startup process. This method features simple circuit design and low design cost.

[0053] Furthermore, as a preferred embodiment of this solution and not a limitation, the emergency start unit 420 includes an emergency battery 421 and an emergency battery management subunit 422. The emergency battery 421 is used to provide emergency starting power when the vehicle is in an emergency. The battery terminal of the emergency battery management subunit 422 is electrically connected to the emergency battery 421. The control input terminal of the emergency battery management subunit 422 is connected to the second control signal output terminal of the main control module 300. The control output terminal of the emergency battery management subunit 422 is electrically connected to the storage battery 100. The emergency battery management subunit 422 is used to control the emergency battery 421 to provide emergency starting power to the vehicle according to the emergency start control signal.

[0054] Alternatively, the emergency battery 421 can be a supercapacitor battery using existing technology.

[0055] In this embodiment, the emergency battery management subunit can ensure that the emergency battery can respond quickly when the battery power is insufficient to start the vehicle, providing a stable starting power and ensuring that the vehicle can start normally in an emergency.

[0056] In a preferred embodiment, the emergency battery management subunit 422 includes a battery management chip U1, a resistor R21, and a capacitor C5. The second control signal output terminal of the main control module 300 is connected to the control input terminal (i.e., the VIN terminal in this embodiment) of the battery management chip U1. An RC filter subunit is also provided between the second control signal output terminal of the main control module 300 and the control input terminal of the battery management chip U1. The RC filter subunit consists of the resistor R21 and the capacitor C5 connected in series. The battery terminal (i.e., the BAT terminal in this embodiment) of the battery management chip U1 is electrically connected to the emergency battery 421, and the control output terminal (i.e., the VOUT terminal in this embodiment) of the battery management chip U1 is electrically connected to the storage battery 100.

[0057] Specifically, when the main control module 300 detects that the battery 100 has insufficient power, the second control signal output terminal of the main control module 300 will output an emergency start control signal. The emergency start control signal is filtered by the RC filter subunit so that the control input terminal of the battery management chip U1 can receive a stable emergency start control signal. After receiving the emergency start control signal, the battery management chip U1 will activate the emergency battery 421 through the battery terminal of the battery management chip U1 and control the charging and discharging process of the emergency battery 421. Since the control output terminal of the battery management chip U1 is electrically connected to the battery 100, the emergency power output from the emergency battery 421 will be sent to the vehicle's starting system to ensure that the vehicle can start smoothly.

[0058] Alternatively, the battery management chip U1 can be implemented using an existing power management chip, and this embodiment does not make specific limitations here.

[0059] In this embodiment, the charging and discharging process of the emergency battery is precisely controlled by a battery management chip to prevent overcharging or over-discharging and extend the battery's lifespan. Secondly, the battery management chip can ensure that the emergency battery outputs a stable starting voltage, avoiding vehicle starting failure due to voltage fluctuations and ensuring a smooth vehicle starting process.

[0060] In a preferred embodiment, the emergency start unit 420 further includes a switch control subunit 423. The input terminal of the switch control subunit 423 is used to obtain a switch command, and the output terminal of the switch control subunit 423 is connected to the switch terminal of the emergency battery management subunit 422. The switch control subunit 423 is used to cut off the operation of the emergency battery 421 after the vehicle starts normally.

[0061] Alternatively, the switch control subunit 423 includes a switch button SW1 and a resistor R22. The first end of the switch button SW1 is grounded, the second end of the switch button SW1 is connected to one end of the resistor R22, and the other end of the resistor R22 is connected to the switch terminal (i.e., the KEY terminal in this embodiment) of the battery management chip U1.

[0062] In this embodiment, after the vehicle starts normally, the user can disconnect the emergency battery to continue providing emergency power to the vehicle by using the switch button SW1. On the one hand, after the vehicle starts normally, the engine will charge the battery to maintain the vehicle's power supply. Disconnecting the emergency battery at this time is to avoid unnecessary power loss and ensure that the emergency battery is only used in emergency situations. On the other hand, it is to prevent the emergency battery from working for a long time and interfering with the vehicle system's main control circuit, thereby damaging the vehicle control system.

[0063] Furthermore, as a preferred embodiment of this solution and not a limitation, the main control module can be implemented using a main controller, such as an MCU (Micro Controller Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or a SOC (System On Chip).

[0064] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a power display module 500, the input terminal of which is connected to the power display terminal of the main control module 300, and the power display module 500 is used to display the current power of the battery 100.

[0065] In a preferred embodiment, the power display module 500 includes resistors R15 and R16, LEDs D2, D3, D4, and D5. The first power display terminal of the main control module (i.e., LED1 terminal in this embodiment) is connected to one end of resistor R15, and the other end of resistor R15 is connected to the positive terminal of LED D2, with the negative terminal of LED D2 grounded. The other end of resistor R15 is also connected to the negative terminal of LED D3, with the positive terminal of LED D3 grounded. The second power display terminal of the main control module (i.e., LED2 terminal in this embodiment) is connected to one end of resistor R16, and the other end of resistor R16 is connected to the positive terminal of LED D4, with the negative terminal of LED D4 grounded. The other end of resistor R16 is also connected to the negative terminal of LED D5, with the positive terminal of LED D5 grounded.

[0066] Specifically, when the battery 100 is fully charged, both the first and second power display terminals of the main control module 300 will output light signals. At this time, because the battery 100 is fully charged, the output light signal is strong, causing all four LEDs to light up. When the battery 100's charge drops to approximately 75% of its total charge, the light signal output from the second power display terminal becomes weaker. Because LED D5 is reverse-connected, LED D5 does not light up, while the other three LEDs light up. When the battery 100's charge continues to drop to approximately 50% of its total charge, the second... The power display terminal no longer outputs a light signal, so LEDs D4 and D5 are not lit. LEDs D1 and D2 are lit due to the light signal output from the first power display terminal. When the battery 100's power continues to drop to about 25% of its total power, the light signal output from the first power display terminal becomes weaker. Since LED D3 is reverse-connected, it is not lit, leaving only LED D2 lit. When the battery 100's power continues to drop, both the first and second power display terminals stop outputting light signals, and all four LEDs are not lit.

[0067] In this embodiment, the power display module can display the current power level of the battery in real time, allowing users to understand the battery's power status in real time. This enables them to take preventative measures based on the battery's power status, avoiding the need to use an emergency battery due to insufficient battery power, which could damage the vehicle's operation.

[0068] Furthermore, as a preferred embodiment of this solution and not a limitation, it also includes a step-down module 600, the input terminal of which is connected to the power output terminal of the battery 100, and the output terminal of which is used to step down the output voltage of the battery 100 to 5V.

[0069] In a preferred embodiment, the step-down module 600 includes a linear regulator U2 and a diode D5. The output terminal of the battery 100 is connected to the positive terminal of the diode D5, the negative terminal of the diode D5 is connected to the input terminal of the linear regulator U2, and the output terminal of the linear regulator U2 is connected to the power supply terminal (i.e., the VCC terminal in this embodiment) of the main control module 300.

[0070] Preferably, the linear regulator U2 is model HT7550. In specific implementation, other linear regulators with the same function can also be used instead of the linear regulator U2.

[0071] In this embodiment, the linear regulator U2 is a low-power linear regulator that converts the battery's output voltage into a stable 5V output voltage, thereby providing the startup voltage for the main control module. The linear regulator U2 can maintain a stable output voltage even under different temperature conditions or when the input voltage fluctuates, ensuring the normal operation of the main control module. Furthermore, the 5V output voltage converted by the linear regulator U2 can also be used in other chips or startup circuits in the vehicle system that require 5V.

[0072] This embodiment also provides a vehicle that includes the start control circuit described above.

[0073] The vehicles mentioned may include, but are not limited to, new energy vehicles, electric vehicles, and fuel vehicles.

Furthermore, due to differences in industry naming conventions, it is not limited to the above names or English names.
