Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly to a control system for an automobile hydrogen production and carbon cleaning device. Background Art

[0002] Automobile hydrogen production and carbon cleaning technology is one of the core technologies of fuel cell electric vehicles (FCEVs). It mainly produces hydrogen through methods such as electrolysis of water or biomass conversion, and uses hydrogen as a clean energy source to achieve zero emissions of automobiles. The automobile hydrogen-oxygen carbon removal technology efficiently removes carbon deposits through chemical means, while improving engine performance and fuel economy, and further extending the service life, etc. Automobile hydrogen production and carbon cleaning technology is the key to realizing the green transformation of automobiles, and further breakthroughs are needed in terms of cost, infrastructure, and industrial chain coordination in the future.

[0003] Some old automobiles do not undergo hydrogen production and carbon cleaning treatment, which will lead to problems such as performance degradation, increased fuel consumption, difficult starting, and other potential problems. Therefore, carbon cleaning is crucial for maintaining the good performance of automobile engines and extending their service life. For this reason, we provide a control system for an automobile hydrogen production and carbon cleaning device. Summary of the Invention

[0004] The purpose of the present invention is to provide a control system for an automobile hydrogen production and carbon cleaning device to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A control system for an automobile hydrogen production and carbon cleaning device includes a central processor. The receiving end of the central processor is signal-connected to the transmitting end of a hydrogen production unit. The receiving end of the hydrogen production unit is signal-connected to the transmitting end of a carbon cleaning unit. The receiving end of the carbon cleaning unit is signal-connected to the transmitting end of an energy efficiency management unit.

[0007] The receiving end of the hydrogen production unit is signal-connected to the transmitting end of a parameter adjustment module and the transmitting end of a hydrogen production raw material monitoring module. The parameter adjustment module is used to accurately control the voltage and current of the electrolytic cell according to the real-time working conditions of the engine (such as load, speed, etc.). For example, when the engine is under high load, the input power of the electrolytic cell is increased to improve the hydrogen generation rate and meet the demand for more gas-assisted combustion. When the load is low, the power is reduced to avoid hydrogen waste.

[0008] A further improvement of the technical solution of the present invention lies in that: the receiving end of the hydrogen production raw material monitoring module is signal-connected to the transmitting end of the water level sensor, and the receiving end of the water level sensor is signal-connected to the transmitting end of the waste heat recovery module. By using a high-precision water level sensor equipped in the hydrogen production raw material monitoring module, the water volume and water quality required for the electrolysis of water and electricity in the module are monitored in real time. When the water volume is insufficient, a water addition prompt is automatically triggered or the vehicle-mounted water tank is connected for water replenishment. If the water quality does not meet the requirements, the filtration and purification device is started or a prompt to replace the water source is given to ensure the stable and efficient hydrogen production process.

[0009] A further improvement of the technical solution of the present invention lies in that: the receiving end of the carbon cleaning unit is signal-connected to the transmitting end of the real-time monitoring module, and the receiving end of the real-time monitoring module is signal-connected to the transmitting end of the infrared sensor.

[0010] A further improvement of the technical solution of the present invention lies in that: the receiving end of the real-time monitoring module is signal-connected to the transmitting end of the pressure sensor, and the receiving end of the infrared sensor is signal-connected to the transmitting end of the safety protection module. Infrared sensors and pressure sensors are installed at key parts of the engine (such as the intake duct, combustion chamber, etc.). By detecting the surface temperature change of the component or the gas pressure fluctuation, the carbon deposition is judged, and the sensor data is analyzed using an algorithm to determine the location and severity of the carbon deposition.

[0011] A further improvement of the technical solution of the present invention lies in that: the receiving end of the carbon cleaning unit is signal-connected to the transmitting end of the carbon capture module, and the receiving end of the carbon capture module is signal-connected to the transmitting end of the purification module.

[0012] A further improvement of the technical solution of the present invention lies in that: the receiving end of the safety protection module is signal-connected to the transmitting end of the leakage detection module, the receiving end of the leakage detection module is signal-connected to the transmitting end of the explosion-proof module, and the receiving end of the explosion-proof module is signal-connected to the transmitting end of the redundant control module. The leakage detection module uses a nanoscale gas sensor + vehicle-mounted camera AI to identify the leakage point. The explosion-proof module uses a hydrogen storage tank carbon fiber composite material + rupture disk safety valve. The redundant control module uses dual controller hot backup to ensure seamless switching in case of failure.

[0013] A further improvement of the technical solution of the present invention lies in that: the receiving end of the purification module is signal-connected to the transmitting end of the particle filtration module, the receiving end of the particle filtration module is signal-connected to the transmitting end of the catalytic conversion module, and the receiving end of the catalytic conversion module is signal-connected to the transmitting end of the feedback module. By using the particle filtration module at the starting end of the automobile exhaust emission pipe, most of the carbon particles in the exhaust gas can be intercepted, preventing them from being directly discharged into the atmosphere and causing air pollution, and avoiding affecting the exhaust smoothness due to excessive accumulation of particles.

[0014] A further improvement of the technical solution of the present invention lies in that: the receiving end of the energy efficiency management unit is signal-connected to the transmitting end of the recovery module, and the receiving end of the recovery module is signal-connected to the transmitting end of the storage and management module. When the vehicle brakes, the kinetic energy of the vehicle would originally be dissipated in the form of heat through the braking system. However, in a hydrogen production and carbon cleaning system with energy efficiency management, a braking energy recovery device will be installed. During braking, the wheels drive the motor to reverse, causing it to enter the power generation mode, converting the kinetic energy of the vehicle into electrical energy. Then, the generated electrical energy is regulated and rectified through a power electronic converter so that it can be stored or directly utilized in a suitable form. The stored electrical energy is stored in the vehicle-mounted energy storage system by the storage and management module, such as a high-performance lithium-ion battery pack or a supercapacitor. Lithium-ion batteries have a relatively high energy density and are suitable for storing a relatively large amount of electricity to meet the subsequent long-term usage requirements. Supercapacitors, on the other hand, have the advantage of fast charge and discharge and can provide a large amount of power in a short period. The combined use of the two can better meet the energy requirements of the vehicle under different working conditions.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by the present invention compared with the prior art is:

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. By setting up a parameter adjustment module to accurately regulate the voltage and current of the electrolyzer according to the real-time working conditions of the engine (such as load, speed, etc.). For example, when the engine is under high load, the input power of the electrolyzer is increased to improve the hydrogen generation rate and meet the demand for more gas-assisted combustion. When the load is low, the power is reduced to avoid hydrogen waste. The hydrogen production raw material monitoring module is equipped with a high-precision water level sensor to monitor the water volume and water quality required for water electrolysis in real time. When the water volume is insufficient, a water addition prompt is automatically triggered or the vehicle-mounted water tank is connected for water replenishment. If the water quality does not meet the requirements, the filtration and purification device is started or a prompt to replace the water source is given to ensure the stable and efficient hydrogen production process. The waste heat recovery module can preheat the electrolyzed water with the waste heat of the fuel cell or internal combustion engine, reducing energy consumption and thus enhancing the vehicle performance.

[0018] 2. By setting up a particulate filtration module at the starting end of the vehicle exhaust pipe, most of the carbon particulates in the exhaust can be intercepted, preventing them from being directly discharged into the atmosphere and causing air pollution, and avoiding affecting the exhaust smoothness due to excessive accumulation of particulates. By using the carrier structure of the catalytic conversion module (such as using porous materials with a large specific surface area as the carrier), the contact area between the exhaust gas and the catalyst is increased to promote the progress of chemical reactions. The exhaust gas after catalytic conversion is then subjected to post-treatment methods such as adsorption and water washing to further remove residual trace pollutants. For example, adsorbents such as activated carbon are used to remove odor substances and a small amount of residual hydrocarbons, and the water washing device is used to remove possible acidic gases (such as nitric acid after the conversion of nitrogen oxides), ensuring that the finally discharged exhaust gas meets stricter environmental protection standards. The feedback module is used to monitor various pollutant indicators in the finally discharged exhaust gas and feed the data back to the vehicle control system. Once it is found that the emissions exceed the standard or other situations occur, the operating parameters of the hydrogen production and carbon cleaning system are adjusted in a timely manner to ensure that the entire system is always in a good operating and environmental protection state, while extending its service life.

DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention will be further described in detail below in conjunction with embodiments:

[0027] Embodiment 1

[0028] As Figures 1-6 shown, the present invention provides a control system for an automotive hydrogen production and carbon cleaning device, including a central processor 1. The receiving end of the central processor 1 is signal-connected to the transmitting end of the hydrogen production unit 2. The receiving end of the hydrogen production unit 2 is signal-connected to the transmitting end of the carbon cleaning unit 3. The receiving end of the carbon cleaning unit 3 is signal-connected to the transmitting end of the energy efficiency management unit 4. The receiving end of the hydrogen production unit 2 is signal-connected to the transmitting end of the parameter adjustment module 21. The receiving end of the hydrogen production unit 2 is signal-connected to the transmitting end of the hydrogen production raw material monitoring module 22. The receiving end of the hydrogen production raw material monitoring module 22 is signal-connected to the transmitting end of the water level sensor 23. The receiving end of the water level sensor 23 is signal-connected to the transmitting end of the waste heat recovery module 24.

[0029] Furthermore, the parameter adjustment module 21 is used to accurately regulate the voltage and current of the electrolytic cell according to the real-time working conditions of the engine (such as load, speed, etc.). For example, when the engine is under high load, the input power of the electrolytic cell is increased to improve the hydrogen generation rate and meet the demand for more gas-assisted combustion. When the load is low, the power is reduced to avoid hydrogen waste.

[0030] The hydrogen production raw material monitoring module 22 is equipped with a high-precision water level sensor 23 to continuously monitor the water volume and water quality required for module water electrolysis. When the water volume is insufficient, a water addition prompt is automatically triggered or the vehicle-mounted water tank is connected for water replenishment. If the water quality does not meet the requirements, the filtration and purification device is started or a prompt to replace the water source is given to ensure the stable and efficient hydrogen production process.

[0031] The waste heat recovery module 24 can preheat the electrolyzed water with the waste heat of the fuel cell or internal combustion engine to reduce energy consumption.

[0032] Embodiment 2

[0033] As Figures 1-6 shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the receiving end of the carbon cleaning unit 3 is signal-connected to the transmitting end of the real-time monitoring module 31. The receiving end of the real-time monitoring module 31 is signal-connected to the transmitting end of the infrared sensor 311. The receiving end of the real-time monitoring module 31 is signal-connected to the transmitting end of the pressure sensor 312. The receiving end of the infrared sensor 311 is signal-connected to the transmitting end of the safety protection module 313.

[0034] Furthermore, infrared sensors 311 and pressure sensors 312 are installed at key parts of the engine (such as the intake duct, combustion chamber, etc.). By detecting the surface temperature change or gas pressure fluctuation of the components, the carbon deposition is judged and the sensor data is analyzed using an algorithm to determine the location and severity of the carbon deposition.

[0035] Example 3

[0036] As Figures 1-6 shown, on the basis of Embodiments 1-2, the present invention provides a technical solution: Preferably, the receiving end of the carbon cleaning unit 3 is signal-connected to the transmitting end of the carbon capture module 32, the receiving end of the carbon capture module 32 is signal-connected to the transmitting end of the purification module 321, the receiving end of the purification module 321 is signal-connected to the transmitting end of the particle filtration module 322, the receiving end of the particle filtration module 322 is signal-connected to the transmitting end of the catalytic conversion module 323, and the receiving end of the catalytic conversion module 323 is signal-connected to the transmitting end of the feedback module 324.

[0037] Furthermore, the particle filtration module 322 can intercept most of the carbon particles (such as PM2.5, PM10, etc.) in the vehicle exhaust at the starting end of the exhaust pipe, preventing them from being directly discharged into the atmosphere and causing air pollution, and avoiding affecting the exhaust smoothness due to excessive accumulation of particles.

[0038] By using the carrier structure of the catalytic conversion module 323 (such as using a porous material with a large specific surface area as the carrier), the contact area between the exhaust gas and the catalyst is increased, promoting the progress of chemical reactions. The exhaust gas after catalytic conversion is further treated by adsorption, water washing, etc. to further remove residual trace pollutants. For example, adsorbents such as activated carbon are used to remove odor substances and a small amount of residual hydrocarbons, etc., and acidic gases (such as nitric acid after the conversion of nitrogen oxides) that may be generated are removed through a water washing device to ensure that the finally emitted exhaust gas meets stricter environmental protection standards.

[0039] The feedback module 324 is used to monitor various pollutant indicators in the finally emitted exhaust gas and feed the data back to the vehicle-mounted control system. Once it is found that the emissions exceed the standard or other situations, the operating parameters of the hydrogen production and carbon cleaning system are adjusted in a timely manner to ensure that the entire system is always in a good operating and environmental protection state.

[0040] Example 4

[0041] As Figures 1-6 shown, on the basis of Embodiments 1-3, the present invention provides a technical solution: Preferably, the receiving end of the safety protection module 313 is signal-connected to the transmitting end of the leakage detection module 314, the receiving end of the leakage detection module 314 is signal-connected to the transmitting end of the explosion-proof module 315, and the receiving end of the explosion-proof module 315 is signal-connected to the transmitting end of the redundant control module 316.

[0042] Furthermore, the leakage detection module 314 uses a nanoscale gas sensor + vehicle-mounted camera AI to identify the leakage point, the explosion-proof module 315 uses a carbon fiber composite material for the hydrogen storage tank + bursting disc safety valve, and the redundant control module 316 uses dual controller hot backup to ensure seamless switching in case of failure.

[0043] Example 5

[0044] As Figures 1-6 shown, on the basis of Embodiments 1-4, the present invention provides a technical solution: Preferably, the receiving end of the energy efficiency management unit 4 is signal-connected to the transmitting end of the recovery module 41, and the receiving end of the recovery module 41 is signal-connected to the transmitting end of the storage and management module 42.

[0045] Furthermore, when the vehicle brakes, the kinetic energy of the vehicle would originally be dissipated in the form of heat through the braking system. However, in a hydrogen production and carbon cleaning system with energy efficiency management, a braking energy recovery device will be installed. Commonly, an integrated motor-generator design is adopted (for electric vehicles or hybrid vehicles). During braking, the wheels drive the motor to rotate in reverse, causing it to enter the power generation mode, converting the kinetic energy of the vehicle into electrical energy. Then, the generated electrical energy is regulated and rectified through a power electronic converter so that it can be stored or directly utilized in a suitable form.

[0046] The stored and managed module 42 is used to store the recovered electrical energy in an on-vehicle energy storage system, such as a high-performance lithium-ion battery pack or a supercapacitor. Lithium-ion batteries have a relatively high energy density and are suitable for storing a relatively large amount of electricity to meet the subsequent long-term usage requirements. Supercapacitors, on the other hand, have the advantage of fast charge and discharge and can provide a large amount of power in a short time. The combination of the two can better meet the energy requirements of the vehicle under different working conditions. The on-vehicle energy management system (EMS) will continuously monitor the state of charge (SOC) of the energy storage system of the module and decide on the distribution of electrical energy according to the set strategy. For example, the recovered electrical energy is preferentially distributed to the sub-links in the hydrogen production module with relatively low energy consumption and low requirements for power quality (such as for powering the control circuit, running a small water pump, etc.), or electrical energy is provided to the metal hydride hydrogen production sub-module at an appropriate time for operations such as gas storage.

[0047] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, any modifications or improvements made without departing from the spirit of the present invention fall within the protection scope of the present invention.
