AN INTERNAL SELF-CHARGING DEVICE FOR ELECTRIC VEHICLESDescriptionTechnical Field

[0001] The present invention relates to the field of electric engineering.Background Art

[0002] Electric vehicles (EV) in Egypt

[0003] Chargers of electric vehicles

[0004] There are concerns about buying electric vehicles, namely lack of fixed and mobile charge points. In Egypt, there are three levels of charging points representing the amount of output energy and the charging speed of electric vehicles.

[0005] In an attempt to cope with the technological development and supporting electric cars with the purpose of reducing carbon emissions, the Egyptian government has made available the electric "Nasr E70" car at the mid of 2022 and planed for establishing 3000 charging stations with multi-speed chargers for electric vehicles.

[0006] There are three methods of charging electric vehicles depending on the used amount of current, the number of kilowatts provided by the charger, and charging time for each vehicle.

[0007] Household Charger

[0008] The household charger is the slowest type of car chargers. It charges batteries by 0%- 80% percent during 10 hours on average. The larger capacity of vehicle battery, the longer the charging time.

[0009] The vehicle charger is connected to an alternating current household electricity source. The charging speed ranges from 1 .4 kW to 3 kW; it may take from 8 to 12 hours for charging depending on the battery quality and capacity. The charger is provided with car and does not need any electrical fits.

[0010] Charging by Alternating Current

[0011] Manufactures of electric vehicles competitively provide fast chargers as an alternative for slow household charger. They have provided AC charging stationsusing household electricity for charging vehicles by 0%- 80% percent during nearly three hours, depending on battery capacity and vehicle type.

[0012] AC chargers are available in public charging stations that start to prevail in Egypt. Likewise, it can be installed at homes, provided that an electricity outlet ranging from 30 to 40 amperes is made available, at a cost of 10000 Egyptian pounds for exported types. The cost may differ according to the manufacture and the vehicle requirements. However, EI-NASR Automotive Manufacturing Company will provide AC chargers for 5000 Egyptian pounds during the coming days.

[0013] DC / Fast Charger

[0014] DC charger is the fastest means for charging electric vehicles. It is available in all charging stations. It used AC or DC power at 480-volt and takes about 20 minutes to one hour for charging with a speed ranging from 43 to more than 100 kW using CCS or CHAdeMO connection. Long charging times may reduce battery life in the long run. Charging cost may exceed that of the first and second charger types by two or three folds.

[0015] It is expected that electric cars manufactures and developers would produce many types of fast chargers in the marathon of developing charging stations of electric vehicles.

[0016] It is expected that electric cars manufactures and developers would produce many types of fast chargers in the marathon of developing charging stations of electric vehicles.Summary of Invention

[0017] The present invention relates to an electric vehicle charger. The inventive charger is driven by compressed air coming from outside during vehicle motion. It is suitable for all kind of vehicles: cars, buses, trucks and motorcycle. It is either built-in or mobile. It is connected to the main charging inverter in the electric vehicle. It is a small and very fast charger suitable for all type of vehicles because it is driven by the compression force of air current and compressed air.Technical Problem

[0018] Charging stations for electric vehicles are few in number due to their limited spread. An electric car driver may drive for long distances to reach a charging station.

[0019] Electricity tarrifs are increasing; hence, the cost of charging electric vehicles is likely to increase in the long run.

[0020] Maintenance costs are high in comparison to fuel-driven vehicles.

[0021] Their range is less than that of fuel-driven vehicles.

[0022] EV charging takes longer time than fueling a gasoline car.

[0023] The charging infrastructure is not available for a comprehensive range and for the speed level till now.

[0024] The manufacture process of electric vehicles has a greater impact on environment than manufacturing a gasoline vehicle.

[0025] Maintaining electric vehicle battery is costly because it is the most expensive component of the EV

[0026] Gasoline Vehicles

[0027] Modern gasoline vehicles excel modern electric vehicles in fast and easy fueling. They are provided with internal combustion engine for burning fuel (petroleum or gasoline) generating the kinetic energy for the car to move. On the contrary, electric vehicles shall be charged continuously to move. Moreover, gasoline vehicles are very fast and easy to be maintained.

[0028] Advantages of gasoline vehicles:

[0029] gasoline vehicles are less expensive

[0030] Fueling is easier and faster

[0031] The range is no concern

[0032] There are a wide variety of vehicles and engines to choose from.

[0033] Fuel power is more efficient than electric batteries

[0034] Disadvantages of gasoline vehicles:

[0035] More total impact on the environment

[0036] Many countries will enforce laws and regulations to limit usage of gasoline vehicles in the future.

[0037] Fuel impurities may badly affect engines of gasoline cars. They are heavier than electric vehicles

[0038] They include a lot of moving parts and components that need to be frequently replaced in comparison to electric vehicles.

[0039] They cause more pollution during motion. However, emissions during EV manufacture process, particularly engine manufacture, are 60% more than that of gasoline vehicles.

[0040] According to statistics, there are less than 8 million electric vehicles nowadays and one billion gasoline vehicles. Assumingly, after 20 years EV numbers will rise to 300-500 million vehicles. This numbers accounts only for 10% (one quarter) of pollution worldwide that reaches 27%. The remaining three-quarters are attributed to planes, trucks, factories, vessels, and mining processes.

[0041] We should inquire about the source of electricity and whether it is a clean energy.

[0042] The majority of electric energy produced in USA results from natural oil burning: nuclear reactors and charcoal. Generating electricity from dams, air, and solar energy does not exceed 12% of total production. Certainly, the matter is worse in less developed countries.

[0043] Electric vehicles account for the same pollution percentage as gasoline cars, starting from its manufacture and for seven years after manufacture and after cutting 100,000 or 150,000 km. In other words, electric vehicles only cause similar or more pollution than gasoline vehicles after being driven for long periods. Concerning the cost, it is based on electricity tarrifs that differ from one country to another.

[0044] The third and most important point is the battery and electricity storage. If the electric vehicle is enhanced to cut 2000 km instead of 500 km per one charge, it will slightly excel gasoline cars and will be better in terms of cost and environmental impact. It seems that the future will be for electric vehicles for political, environmental and economic considerations.

[0045] Different types of electric vehicles chargers have different outputs that affect the charging period. Electric vehicles are available nowadays everywhere. Before buying an electric vehicle, you need to know everything about household charging and the different charging levels.

[0046] The best electric vehicles' batteries

[0047] The difference between types and levels of electric vehicle's batteries

[0048] The following section covers the differences between the main EV charging methods for as well as the advantages and disadvantages of each.

[0049] There are five new types of electric vehicles provided with free charging for a number of years.

[0050] Charging level 1 (120V)

[0051] Charging level 1 is more complicated than expected. When buying electric vehicle, you get household charger cable as well. The charger cable is connected to a traditional 120V household plug. In this way, you can immediately charge your car without making any modifications to the electric system in your home.

[0052] The only drawback of charging level 1 is its low speed. L1 charging allows recovering 5 miles of the car range per one charging hour (8 km), providing about 50 miles (80 km) of the driving range the next morning.

[0053] Fifty miles of battery range is more than sufficient for driving inside the country. The major advantage of the slow charging in this level is avoiding battery deterioration that may happen in fast continuous charging.

[0054] Car charger cable: Tesla J1772

[0055] Battery charging speed: 4-8 km / hour

[0056] Charger location: home, work and public places

[0057] Level 2 charging (208-240V)

[0058] If you want to install level 2 charger in your home, you need to consult a specialist. Level 2 charging is suitable to those who travel for very long distances. Charging car by 100% is a priority for all electric vehicles' owners.

[0059] Level 2 charging permits recovery of the car range by about 100% during a short period using 240V plug. This will be ideal if you travel for more than 50 miles (80 km) daily accompanying your EV charger.

[0060] As above mentioned, you should consult a professional electrician for establishing level 2 charging system. Once the electrician installs L2 charger and 240v plug, your car will be ready for charging.

[0061] Using L2 charger daily may cause battery deterioration because it is nearly fully charged in every charging process. However, you should do not hesitate to charge the car to the level that meets your need.

[0062] Vehicle charger cable: Tesla J1772

[0063] Vehicle charger cable: Tesla J1772

[0064] Charger location: home, work and public places

[0065] Level 3 charging (400-900V)

[0066] Level 3 charger is a fast one that uses direct current. Taking Hyundai IONIQ 5 and Kia EV6 as examples, battery of Hyundai IONIQ 5 is recharged from 10% to 80% during 18 minutes by L3 charger. It is ideal for long journeys where speed is crucial.

[0067] Level 3 charging is only available in public charging stations. You cannot install one in your home. Actually, it is not beneficial for you to do so, using public charging station is more practical.

[0068] The disadvantage of DC fast charger is battery deterioration by time.However, it is rarely to be used to the extent of affecting the battery. Do not hesitate to use DC fast charger if needed. DC charging stations have become more available. As big companies such as Electrify America and Tesla join investment in car charging stations in Saudi Arabia and Gulf states, it will spread more and more.Solution to Problem

[0069] According to the present invention, and contrary to the traditional art, a charger is fixed in the vehicle engine for auto-charging. The car owner does not need to depend on Rally charging at home or electric stations for charging; heonly needs to buy the charger or fix it in the car engine. It works as an internal closed charging circuit during car movement only. It is safe because it resembles a closed box working by compressed air for producing the direct current needed for battery charging. Once charging is complete, an electronic breakaway occurs. There is an auto-cooling system for the whole device through the internal turbines that generate DC as well as continuous air for cooling the electronic circuits and main converter.

[0070] The currently available type of charger is overnight household chargers. They are very slow; the charging process takes 8-11 hours. Mobile chargers are also available; they necessitate providing a fixed supply of electricity. The vehicle driver may, alternatively, seek charging at main stations that may waste his time. The inventive charger is a built-in device that works as a closed circuit for continuous vehicle charging.Advantageous Effects of Invention

[0071] Which is better: electric or gasoline vehicles?

[0072] Due to the increase in fuel prices, it is important to consider electric vehicles for being cost-effective. Moreover, there is a global trend towards using EV for being environment friendly. However, gasoline cars are still dominant for its known merits.

[0073] Although many admire electric vehicles for their modern capabilities, a large number of people think it is too early to be trusted.

[0074] Both electric and gasoline vehicles have their own advantages and disadvantages.

[0075] A comparison will be made between gasoline and electric vehicles in this disclosure.Brief Description of DrawingsFig.1

[0087] The current invention relates to a built-in charger for all electrically charged vehicles, such as cars, buses, trucks and motorcycle. It consists of various electric and electronic circuits and electricity generating turbines. It is a novel invention that saves money, fuel and time worldwide; all world nations seek clean energy to reduce environmental and atmospheric pollution resulting from exhaust and carbon emissions from vehicles. The current invention depends on a novelmethod of operation. According to the invention, energy is generated and all types of battery are charged. For example, electricity is generated- during vehicle motion- by the driving force of compressed air inside the pipe and air paths at the front of the car, leading to fast rotation of the turbine. As a result, an electric current is generated. It flows into the voltage stabilizer that charges, in turn, the device battery at 12V and 70 Amp during motion. Afterwards, the current flows from the battery to an inverter circuit for increasing voltage from 12V to 220V. It then passes to the protection fuse of the inverter ampere circuit that provides protection against the reversal of high voltage from the converter to the inverter circuit. The fuse is automatically fused, for circuit and device protection, in case of electric current reversal if current exceeds 220V. The current flows into voltage-raising converter. It raises the voltage from 220V to multiple voltages starting from 220V, 240V, 380V, 400V, 450V.

[0088] The converter increases voltage and alternating current. The current then flows to a multi-step power switch to adjust the required voltage to phase 1 , 2 or 3. The current then flows to an inverter for converting the high voltage from alternating current to direct current which is required for battery charging. However, according to the current invention, the direct current flows to the main inverter of the electric vehicle and then to the battery for fast charging. According to the invention, car charging will be easier and faster. Inside each electric car, there are a number of batteries that may reach sixteen ones, depending on the manufacture and the battery type.

[0089] As an example, we will divide batteries into groups A&B, each containing 8 batteries.

[0090] Group A is fully charged and connected to the car when driven. Group A is fully charged according to the invention. Excess charge goes to group B. When group A is out of charge, the computer on-board converts car engine to be driven by group B. At the same time, group A is charged during car motion, and so on.

[0091] In this way, there will be no need for household charging or car charging stations of any level, such as charger A (110 Volt), charger B (220 Volt), charger C (380-450 Volt), and fast charger (400-900 Volt) that takes 30-45 minutes for charging. On the contrary, according to the current invention, the car is providedwith a high voltage built-in charger that works during car motion. There is an extra battery inside the electric circuit. It is always charged for providing current in case of battery / circuit damage until reaching the nearest car maintenance centre. The invention is cost effective; no petroleum or gasoline is used, no exhaust in emitted, no harm is caused to man, animal or environment. It can be applied to all kinds of vehicles, trucks, motorcycle, trains and motor boats. Different driving forces are applied either by compressed air or compressed water current. Air or water gets into electric turbines- during vehicle motion- for generating power and charging batteries in all means of transportation. Accordingly, effort, time and money are saved.Industrial Applicability

[0092] The present invention provides an alternative to fuel in the future. Petroleum and fuel will be depleted. The use of fuel of different types in the various life activity and equipments causes environment pollution in all parts of the world. Therefore, the developed countries are competing with each other in finding an alternative energy source. Egypt can be a leading country in this field, by generating clean energy form solar energy for all vehicles. The invention can be applied to generate clean energy for trains, undergrounds, vehicles, motor boats through compressed air / water current. Such clean energy is used for charging batteries by method A&B alternatively. Thus, there will be no need for fuel i
