Description

A hydrogen vehicle and a power supply system for such a vehicle

Background of the invention

Today's cars are commonly using fuel, electricity, or both (e.g. hybrid cars). A disadvantage of fuel cars is that they are polluting and harmful to the environment due to emission of gases as a result of fuel combustion, meaning that these cars are not environmentally friendly. A disadvantage of electric vehicles is that it takes some time to charge these cars with the current technology. The present invention is intended for hydrogen combustion engines and such vehicles. The use of hydrogen as a fuel causes zero emissions, and with the present invention the lost energy due to burning of hydrogen will be captured and will be reused again in order to produce hydrogen by the energy capturing system of the car. With this invention the engine will be about 50% more efficient than the engines without this invention due to energy reusing and/or due to the external source of energy (e.g. the solar energy).

The present invention relates to motors and/or engines and vehicles using renewable energy. The purpose is to reduce carbon emissions and to make engines, and vehicles with such engines, more environmentally friendly when in use.

The present inventive concept is about power generation from renewable sources and capturing loss energy and reusing it again.

This invention concerns a hydrogen vehicle and a power supply system for such a vehicle.

Brief description of the inventive concept

The idea is to use sun energy (photovoltaic solar energy) to produce electricity and to use this power (i.e. the produced electricity) to produce hydrogen by using a hydrogen generator for further use in a vehicle engine in a vehicle. The idea is also to capture loss energy from the above process and/or other processes in the vehicle and to reuse it (i.e. use it again).

This invention concerns use of renewable energy in internal combustion engines by using hydrogen and capturing other energy, in addition to solar energy, from hot water, vibration, linear motion, rotary motion and heat to also produce electricity and use it in production of hydrogen.

This invention is intended in general for vehicles, such as e.g. cars, boats, ships, ferries, train locomotives, airplanes, etc., but can be used in other industrial applications like e.g. power generation. For vehicles the intension of the invention is to use sun energy by using photovoltaic constructed roof thereon. The electricity produced by a solar panel will be saved in a battery. And the electricity from the battery will be used again to produce hydrogen. The advantage of using hydrogen in an internal combustion engine is to reduce the emissions and in addition it will be faster to tank and use the produced hydrogen than to charge for example an electrical vehicle. Hydrogen is highly flammable, and storage and transport are expensive, but producing hydrogen in the moving unit will reduce the cost considerable.

By using the solar panel on or in the vehicle's roof electricity will be produced and will be transferred by cables and/or by wireless charging (e.g. by inductive charging) through the charge controller to the battery. Electricity from the power stored in the battery will be used to produce hydrogen from water in a water tank by means of the hydrogen generator. The hydrogen produced by the hydrogen generator will be compressed into a hydrogen tank by means of a compressor. The hydrogen will be used in the hydrogen combustion engine. The energy from burning the hydrogen will be formed into several types of energies.

The main type of energy is motion of the vehicle and others are secondary types, such as kinetic, linear motion, vibration and heat.

The kinetic energy will be activated with braking and/or with downhill movement and can be captured by using rotating generators fixed on the rotating shafts of the vehicle. With braking and/or downhill motion the rotating generators will produce AC electricity. The rotating elements are surrounded by a large magnet and coils of copper wire. The magnet is rotated as a result of the spinning wheels, and this results in a powerful stream of electrons, therefore converting the mechanical energy into electric energy. The AC electricity produced by the rotating generators will be saved in the battery through a converter.

The linear motion energy will be connected to the converter and to the battery. A permanent magnet linear generator is a type of generator that uses linear motion to generate power. It uses permanent magnets to create a magnetic field, wherein motion of the translator will cause a magnetic flux change in the circuit formed by windings to generate power and convert mechanical energy into electrical energy. There are two types of linear motions:

i) Continuous linear motion from a shock absorber (strut) which will be used to produce electricity.

By integrating a linear generator (alternator) with the shock absorber the linear generator will produce electricity from the movement of the shock absorber. The electricity from the linear motion generator (alternator) is AC and therefore will be connected to the battery through the converter.

ii) The tyres of the vehicle are constantly being deformed as they spin, and this causes a radial linear motion around the center of the tyres. From this radial linear motion electricity can been produced. The variation of the tyre radius with the spin causes a linear motion along the radius, and this linear motion will be used to produce electricity. The electricity will be AC and will be connected to the battery through the converter, as mentioned with regard to the strut. The electricity from the battery will be used by the hydrogen generator to produce hydrogen as mentioned above.

A vibration powered generator is a type of electric generator that converts the kinetic energy from vibration(s) into electrical energy. The vibration generators can be located and/or integrated anywhere in the vehicle, e.g. on the engine, axles and/or vehicle body. The electricity from the vibration generator is AC, and it is produced by electromagnetic based generators using induction to convert the kinetic energy of the vibrations into electrical energy. They consist of magnets attached to a flexible membrane or a cantilever beam and a coil, and thereafter they will be connected to the battery through the converter (in a wired or wireless manner).

There is another type of generators depending on pressure and vibration and being called a piezoelectric vibration generator. A piezoelectric crystal is placed between two metal plates. At this point the material is in perfect balance and does not conduct any electric current. Mechanical pressure is then applied to the material by the metal plates, which forces the electric charges within the crystal out of balance, and the produced current is AC. In the vehicles piezoelectric vibration generator(s) can be integrated in for example a control arm joint, motor mount and strut mount rubber.

Different types of heat can also be used in the system to produce electricity. The heat from combustion of hydrogen and the heat from friction between the tyres and the ground can be used to produce electricity.

The hydrogen combustion engine becomes warm due to hydrogen burning and this heat can be used to produce electricity by using a thermoelectric generator (TEG), also called a Seebeck generator, which is a solid-state device that converts heat flux (temperature differences) directly into electrical energy through a phenomenon called the Seebeck effect. The thermoelectric generator (TEG) can be integrated with the engine in order to produce electricity. The electricity from the thermoelectric generator (TEG) will be connected to the battery to further be used in producing hydrogen.

Electricity can also be created from the tyres spin and heat differences by using special semiconductor materials, like e.g. bismuth telluride, and this electricity will be DC.

Thermoelectric tubes can be used in an engine cooling system to produce electricity. The cooling system of the car is a closed loop, and the cooling medium is water. The hot water is flowing from the cylinder block of the engine, by means of a water pump and tubes, to the radiator to be cooled by ambient air. The water heats because of the burning of the hydrogen in the engine cylinders and will be cooled in the radiator by the ambient air. This temperature variation will be used to produce electricity by using thermoelectric tubes and thermoelectric generator (TEG). The thermoelectric tubes will be used in the radiator and the thermoelectric generator (TEG) will be used in the engine block.

Thermoelectric tubes can be used in an exhaust system of the vehicle as well. The exhaust system in this invention consists of a condenser, a pipe and a muffler. Due to burning of hydrogen in the engine cylinder water vapour will exit from the exit valve to the pipe and then to the condenser. Some of the hot vapour will be condensed to become a water in the condenser by means of ambient air and this water will be added to the water tank in the vehicle by tubes and a water pump. The remained water vapour will be released to the environment through the pipe, the muffler and a tail pipe. Thermoelectric tubes can be used in the condenser, pipe and muffler in the exhaust system to produce electricity due to various temperature of the water vapour and of the ambient temperature (that is the temperature difference between the water vapour and the ambient temperature).

The electricity from the thermoelectric tubes and the thermoelectric generator (TEG) will led to the battery (in a wired or wireless manner) and then will be used in producing hydrogen by the hydrogen generator.

The working principle, components placements and connection of the system utilizing kinetic, vibration energy and heat energy have been explained in the enclosed drawings and the following explanations above and below, and the charging of the battery will be wired (by means of cables) or wireless (e.g. by inductive charging).

Detailed description of the embodiments of the invention

For a more complete understanding of the concept and possible embodiments of the present invention and its advantages, an exemplary embodiment will be explained in detail below. As discussed above, this invention relates generally to a power and hydrogen generation for use in hydrogen combustion engines in vehicles. By capturing waste energy and converting it into electricity the efficiency of the engine will be raised, and this will thus reduce the emission of carbon dioxide in the nature in generally.

Fig. 1 illustrates the exemplary embodiment of the present invention concept. A power generation and supply system 20 for a vehicle 25 is shown in fig.

1. The system 20 comprises a hydrogen generator 10 connected to a battery 9 and a water tank 14. The battery 9 feeds the hydrogen generator 10 with power and the water tank 14 is connected to the hydrogen generator 10 to feed the hydrogen generator 10 with water. The hydrogen generator 10 is configured to produce hydrogen from the water. The hydrogen generated by the hydrogen generator 10 will be compressed by a compressor 11 into a reservoir tank 12. The compressor 11 can also be connectable to an external fuel or hydrogen resource 16. Alternatively, and/or additionally, the reservoir tank 12 can be connectable to the external fuel or hydrogen resource 16. The external fuel or hydrogen resource 16 is responsible for filling the vehicle 25 with fuel, e.g. hydrogen, at a fuel station. Hydrogen from the reservoir tank 12 is fed to a hydrogen combustion engine 13 of the vehicle 25 in order to start and drive it. The hydrogen engine 13 is configured to provide motion and power energies for the vehicle 25. Hydrogen fuel is a zerocarbon fuel burned with oxygen and forming water with the release of energy. Thus, the rests / residuals from the combustion process in the hydrogen combustion engine 13 are water vapour 17. The water vapour 17 can be led back (after cooling it down by a condenser 26) to the water tank 14 by means of a pump and the remaining vapour can be led to the environment through an exhaust system 30.

The battery 9 is connected to a charge controller 8. The charge controller 8 regulates the power to and from the battery 9. The charge controller 8 regulates the power from different power sources in the vehicle 25, such as e.g. thermoelectric tube(s) 1, thermoelectric generator(s) (TEG) 2 and/or solar panel(s) 3 and from a converter 7 to which it is connected.

At least one thermoelectric tube 1 is used in at least one of: the cooling system 31 and the exhaust system 30 which consist of a condenser 26, a pipe, a muffler 32 and a tail pipe 33 of the vehicle 25. Thermoelectric technology is the direct energy conversion from heat into electricity. The hot water due to burning of the hydrogen in the combustion engine 13 can be taken through a tube to the condenser 26 to be condensed where the water flows to the water tank 14 and the vapour to the pipe and the muffler 32. The hot water out of the cylinder block of the engine flows to the radiator to be cooled and flows to the engine again to cool it (the cooling system 31). The temperature variations in both the cooling system 31 and the exhaust system 30 will be used to produce electricity by using thermoelectric tubes.

The electricity from said at least one thermoelectric tube 1 is DC and will be connected (in a wired and/or wireless manner) to the charge controller 8 to charge the battery 9 in the system 20.

At least one thermoelectric generator (TEG) 2, also called Seebeck generator, is used in the vehicle 25 and is a solid-state device that converts heat flux (temperature differences) directly to electrical energy. By integrating said at least one thermoelectric generator 2 with the engine body of the engine 13 the heat from the engine body will be converted to electricity. In addition, at least one thermoelectric generator 2 can be integrated on a gearbox 29 and/or an exhaust system 30 of the vehicle 25. The electricity from said at least one thermoelectric generator (TEG) 2 is DC and will be connected (wired and/or wireless) to the charge controller 8 to charge the battery 9. Yet in addition, due to friction between the tyres 15 and the ground, heat energy from the tyres 15 can be converted directly to electricity by at least one thermoelectric generator 2. That can be done by integrating thermoelectric materials with the tyres 15.

At least one solar panel 3 in a photovoltaic (PV) system is configured to convert the sun's radiation, in the form of light, into usable electricity. Said at least one solar panel 3 can be fixed or arranged on at least one of: the roof of the vehicle 25, the front trunk of the vehicle 25 and/or the trunk of the vehicle 25 (fig.3 and fig.4). The electricity from the solar panel(s) 3 is DC current and therefore the solar panel(s) 3 will be connected (wired and/or wireless) to the charge controller 8 and then to the battery 9 for charging it, in the same manner as for the thermoelectric generator(s) 2 and/or the thermoelectric tube(s) 1.

Furthermore, it is possible to use the radial linear motion from the tyres 15 of the vehicle 25 in order to also produce electricity which can be stored in the battery 9 through the converter 7 and can be used to produce fuel, e.g. hydrogen. At least one linear radial motion generator 5B can be designed with the special requirement to meet the radial linear motion of the tyres 15. The radius of the tyres 15 of the vehicle 25 is larger at the top of the tyre 15 than the down point of the tyre 15 on the ground level due to the weight of the vehicle 25. There is no constant radius variation in the motion of the vehicle 25. Said at least one linear radial generator 5B can be designed to endure compact and shocks. The linear radial generator(s) 5B, which can be integrated with the tyres 15, will not affect or resist the spin of the tyres 15, but will just make the tyres 15 more efficient by affecting the elasticity of the tyres 15.

Furthermore, at least one linear generator (alternator) 5A can be integrated with shock absorber(s) / strut(s) 28 of the vehicle 25, as shown in fig.4 and fig.5. The current produced will be AC and will be connected (wired and/or wireless) to the converter 7 and then to the battery 9.

As shown in fig.3 at least one rotating generator 4 can be fixed on the rotating shafts or axles 27 of the vehicle 25 in order to utilize kinetic energy for thus to produce electricity. The rotating generator(s) 4 can be activated under the braking and/or downhill motion or movement of the vehicle 25 and can then produce AC current. The rotating generator(s) 4 can be connected together and then is being connected (wired and/or wireless) to the converter 7 in order to convert AC to DC, and thereafter is being connected from the converter 7 to the charge controller 8 and finally to the battery 9.

Additionally, electricity from at least one vibration generator 6C can be utilized. The vibration generator(s) 6C can be placed everywhere on the vehicle 25 and specially on the engine 13, the axles 27 and/or the gearbox 29 of the vehicle 25 (see for example fig.2 and fig.3).

Also, electricity from at least one piezoelectric vibration generator 6D can be utilized and can be integrated in the control arm joint 34, motor mount 35 and strut mount rubber 36 to produce electricity and to store it in the battery 9 through the converter 7 and the charge controller 8 (in a wired or wireless manner).

The AC power from the vibration generators 6C and 6D will be connected to the converter 7 and then to the charge controller 8, finally to the battery 9.

The electricity from the above-mentioned components (i.e. thermoelectric tube(s) 1, thermoelectric generator(s) 2, solar panel(s) 3, rotating generator(s) 4, linear generator(s) / alternator(s) 5A and 5B, and vibration generator(s) 6C and 6D) as shown in fig.2 and fig.3 will charge the battery 9 and the battery 9 will feed the hydrogen generator 10 in order to produce hydrogen for combustion in the engine 13.

All the components of the system 20 should be connected to respective ones thereof by means of suitable pipes and/or cables and/or inductive (wireless).

The system 20 according to the present invention is suitable for hydrogen vehicles. By modifying the system 20 it can also be made suitable for electric vehicles. The system 20 can also be used in other industrial applications such as for example in power generation.

Additional modifications, alterations and adaptations of the present invention will suggest themselves to those skilled in the art without departing from the scope of the invention as defined in the following patent claims.
