For more detailed structure and composition of the first battery assembly 30 and the second battery assembly 40 which are graphene batteries with capacitance characteristics, refer to the chinese patent application with application number 201710196595.6.

Referring to fig. 1 again, the oil power generation system 50 is a combination of an oil internal combustion engine 52 and a first generator 54, and the oil internal combustion engine 52 and the first generator 54 of the oil power generation system 50 are respectively connected to the control management system 20; therefore, the control management system 20 detects that the first battery assembly 30 or the second battery assembly 40 is low in power and needs to be charged, and can control the oil-fueled internal combustion engine 52 to start, so that the first generator 54 generates electric power, and the electric power charges the first battery assembly 30 or the second battery assembly 40 through the control management system 20.

Further, the magnetic energy power device 60 is a device capable of generating continuous motion (rotation) by utilizing magnetic attraction and/or magnetic repulsion force, for example, a permanent magnet is disposed on the surface of a rotatable element (blade set) and is correspondingly and fixedly mounted to a permanent magnet, and when the rotatable element is not constrained, the magnetic attraction and/or magnetic repulsion force generated by the corresponding magnet can drive the rotatable element to rotate continuously. The torque generated by the rotatable element is applied to the second generator 64 such that the second generator 64 generates electrical energy. The magnetic energy power device 60 is only for illustration and not limited thereto.

Therefore, the magnetic energy power device 60 can be operated immediately to generate power to continuously charge the first battery assembly 30 and the second battery assembly 40 without starting power or with small starting power. For example, when the first battery assembly 30 or the second battery assembly 40 is short of power to supply the requirement for starting the battery motor 12, the magnetic energy power generation system 60 can be used to generate power to start the battery motor 12, and the first battery assembly 30 and the second battery assembly 40 can be charged.

In addition, the present embodiment further includes a third generator 80 coupled to the control and management system 20 and a transmission system 82.

The electric energy generated by the third generator 80 is used to charge the first battery assembly 30 and/or the second battery assembly 40 by the control management system 20.

Both the engine 14 and the oil-fueled internal combustion engine 52 of the oil power generation system 50 described above use modified methanol fuel; wherein, the composition of the modified methanol fuel comprises: 95-99% of methanol; the cosolvent comprises isobutanol which accounts for 0.1-0.5%; the proportion of the stabilizer is 0.05-0.15%; the purifying agent accounts for 0.05-0.15 percent; 0.08-0.22% of lubricant; the solubilizer comprises polysorbate 80, which accounts for 0.08-0.22%; the content of the rust-proof corrosion-relieving preparation is 0.05-0.15%.

Another possible example is a methanol ratio of 95-99%; the cosolvent comprises isobutanol which accounts for 0.1-0.5%; the stabilizer is ethynyl methanol, and the proportion of the stabilizer is 0.05-0.15%; the purifying agent is trihydroxy triethylamine, which accounts for 0.05-0.15%; the lubricant comprises oleic acid, and the proportion of the oleic acid is 0.08-0.22%; the solubilizer comprises polysorbate 80, which accounts for 0.08-0.22%; the rust-proof corrosion-relieving preparation comprises methyl benzotriazole, and the proportion of the methyl benzotriazole is 0.05-0.15%; the power promoting agent accounts for 0.4-0.6 percent.

The power improver comprises water, potassium nitrate and fusel oil, wherein the mass ratio of the water in the power improver is 30-50%. The ratio of water in the whole can be less than 1%. Because hydrogen can be generated after the water and the methanol are mixed and reacted, and the hydrogen can be combusted to further provide power, the effect of power enhancement can be achieved by adding the water.

The modified methanol fuel can also comprise ethanol, propanol or butanol within a preset mass ratio; further, the individual mass or the sum of the individual masses of ethanol, propanol or butanol is less than the mass of methanol.

And the rest is one or more components selected from an antifreeze solubilizer, a combustion improver, an oxygen increasing agent, a boiling point regulator, a calorific value enhancer, a detergent, a flavoring agent or a flash point regulator according to actual requirements.

The combustion improver may be selected from one or more of ethanol, acetone or a combination of ethers. The combustion improver is used for assisting and improving the combustion efficiency of the methanol gasoline.

The oxygenation agent can be selected from one or more of potassium permanganate, hydrogen peroxide and potassium nitrate. The oxygen increasing agent is used for assisting and improving the combustion efficiency of the methanol gasoline.

The boiling point modifier may be selected from a combination of one or more of acetone, diethyl ether, dimethyl ether, petroleum ether or butane. The boiling point of the liquid is critical and is typically around 65 degrees. However, when water and other additives are added to the methanol gasoline, the boiling point of the methanol gasoline is changed and needs to be adjusted. The invention can properly adjust the boiling point of the methanol gasoline by the boiling point regulator, and the methanol gasoline can be smoothly vaporized and applied.

The caloric value enhancing agent may be selected from a combination of one or more of fusel alcohols, petroleum ethers, or ketones. The main fuel (methanol) and the combustion improver sometimes do not increase the calorific value, which causes troubles in the use process, so that the calorific value must be increased to improve the use efficiency.

The detergent may be selected from the group consisting of n-propanol, isopropanol, limonene, combinations of one or more of the cyclic rings. The flavoring agent may be selected from a combination of one or more of camphor oil, ethyl butyrate, lavender oil, or other flammable fragrances. After the methanol gasoline is prepared, peculiar smell is generated sometimes, and the effects of regulating smell and supporting combustion can be achieved by virtue of the detergent and the regulator.

The flash point modifier may be selected from a combination of one or more of petroleum ether, diethyl ether, dimethyl ether or acetone. The flash point regulator can increase the evaporation capacity of methanol gasoline, thus increasing the pressure in the container, reducing the flash point, facilitating ignition and feeding for combustion.

One or more of the above-mentioned solubilizing agents for antifreeze, combustion improvers, oxygenates, boiling point modifiers, heating value enhancers, detergents, flavoring agents or flash point regulators may be referred to as additive aids, and the additive aids may be added appropriately according to actual needs.

Referring to fig. 3, the start mode of the hybrid electric vehicle disclosed in the present invention includes: and the control management system is used for detecting the electric quantity of the first battery pack and the second battery pack. If the electric quantity of at least one battery meets the requirement of starting the battery motor, the battery is used for starting the battery motor. If the control management system detects that the electric quantity of the first battery assembly and the second battery assembly is not enough to start the battery motor, the magnetic energy power generation system is started, and the battery motor is started by the electric power generated by the magnetic energy power generation system.

Referring to fig. 4, the traveling power switching mode of the hybrid vehicle according to the present invention includes: after the battery motor is started, the control management system detects the change of the electric quantity of a battery assembly (such as a first battery assembly) supplying power to the battery motor in real time, when the electric quantity of the battery assembly (the first battery assembly) supplying power at present is reduced to reach a preset value, the control management system controls to immediately execute a switching action, and another battery assembly (a second battery assembly) is used as a power supply battery assembly of the battery motor. Secondly, when the vehicle speed reaches a high speed state, the control management system can control the battery motor to stop running and control the engine to start to output power.

Referring to fig. 5, the charging mode of the hybrid electric vehicle disclosed by the present invention includes: during the running process of the vehicle, the magnetic energy power generation system can operate and continuously charge the first battery assembly and the second battery assembly. By charging the two battery assemblies through the magnetic energy power generation system at any time, the problem after the battery assemblies are out of power can be relieved. The third generator is a device configured for the existing automobile, so that electric energy can be automatically generated during the traveling process of the automobile, and the first battery assembly and/or the second battery assembly can be charged. However, the use of this third generator is not sufficient to fully satisfy the charging requirements of the hybrid vehicle.

Referring to fig. 6, in a normal state, the embodiment of the invention uses the magnetic energy power generation system to generate power and charge the battery assembly. However, when the control management system detects that the magnetic energy power generation system is not enough to provide sufficient power, for example, the magnetic energy power generation system fails, the oil power generation system is started to generate power to charge the first battery assembly and/or the second battery assembly. .

As described above, the engine 14 and the oil engine 52 may be the same component. In other words, the first generator 54 may be coupled to the engine 14. When neither of the

battery assemblies

30 and 40 require charging, power from the engine 14 need not be transferred to the first generator 54; when both of the battery packs 30 and 40 need to be charged, the power of the engine 14 is transmitted to the first generator 54 to generate electricity.

The engine 14 and the oil-gas engine 52 of the hybrid electric vehicle provided by the embodiment can use modified methanol as fuel. Because the common methanol gasoline is the mixture of methanol and gasoline with different proportions, the problems of cold start, starting shake and starting pause and frustration can be avoided when the methanol gasoline is used for the conventional automobile internal combustion engine, and the disclosed methanol gasoline can reduce pollution but cannot really achieve the effect of environmental protection; however, the present invention can provide better combustion efficiency and smooth power transmission at high speed by using the modified methanol fuel without changing the structure of the engine and the internal combustion engine. In addition, the modified methanol combustion has cleaner exhaust gas, and particularly, the methanol fuel can be directly added with water or mixed with water in a combustion chamber of the oil engine, so that the combustion efficiency can be improved under the state of forming oil-water mixture (water-in-oil emulsion), and the undesirable components in the exhaust gas are obviously reduced. The modified methanol fuel has high combustion efficiency, so the modified methanol fuel can meet the requirement of environmental protection.

In addition, when the automobile runs at high speed, the modified methanol fuel is used in the existing internal combustion engine, and the combustion is more complete, so that the power can be improved, the oil consumption can be reduced, the emission of harmful tail gas can be effectively and greatly reduced, and the effect of reducing pollution is really achieved.

The gasoline-electric hybrid vehicle disclosed by the invention runs in an electric vehicle mode at low speed and in an engine-power vehicle mode at high speed, particularly uses modified methanol fuel to solve the problem of vehicle shaking during starting or cold starting when the engine uses general environment-friendly fuel.

Next, the first battery assembly 30 and the second battery assembly 40 of the present embodiment are both graphene batteries, which have capacitance characteristics, so that higher charge and discharge efficiency can be provided, thereby improving the traveling efficiency and battery charging efficiency of the electric oil vehicle.

The internal combustion engine and the brake are generally used for generating recharging, extra fuel is consumed during charging, and the recharging mode can only supplement a small amount of battery power during charging. The invention particularly adds the magnetic energy power generation system with energy multiplication to charge the

battery assemblies

30 and 40, so that less energy can be consumed, and the electric quantity of the batteries of the

battery assemblies

30 and 40 is supplemented by a cyclic charging mode, so that the consumption of fuel required by charging can be reduced, and the charging quantity of the

battery assemblies

30 and 40 can be increased, thereby improving the cruising power and the high charging efficiency of the vehicle.

In addition, the magnetic energy power generation system 60 disclosed in this embodiment can be started by external force, so even if the first battery assembly 30 and the second battery assembly 40 cannot provide electric energy, the engine 14 and the oil-fueled internal combustion engine 52 run out of oil, the magnetic energy power generation system 60 can still operate smoothly and provide electric power, so that the problem of driver panic can be solved.

The above description is of the preferred embodiment of the present invention and the technical principles applied thereto, and it will be apparent to those skilled in the art that any changes and modifications based on the equivalent changes and simple substitutions of the technical solutions of the present invention are within the protection scope of the present invention without departing from the spirit and scope of the present invention.
