A concept platform of solar mobile power system
Electrical equipment is omnipresent in today’s society. Therefore, electricity-storing and electricity-providing means become more important every day. In a society which has the means to build and maintain an electrical power grid, electricity can be delivered in every household in a very cost-effective way. However, in many cases there is a need for electricity to power electrical equipment at remote or less- developed areas where no connection to an electrical power grid is provided. At such places, one can use batteries or fossil-fuel generators to provide electrical power.
However, batteries run out of power if they are not recharged and with the depletion of fossil fuels it has become costly to generate electrical energy via the burning of fossil fuel and this latter solution is not environmental-friendly due to e.g. the large C02 production. Therefore, there remains a need in the art for improved systems for generating and/or providing electrical power at remote locations which are ecologically justified.
Up to this day, the three main renewable energy sources remain wind energy, hydro- energy and solar energy. Electricity can be typically produced from wind energy by means of e.g. a wind mill or similar, from hydro-energy by means of e.g. a water mill or similar and from solar energy by means of photovoltaic cells. Since a remote location may not always have flowing water nearby, but will always be subject to sunshine or wind at least part of the time, it seems logical that a mobile ecological system for providing electricity at remote locations will comprise means for generating electrical energy from wind energy and/or from solar energy. Such a system is disclosed in patent application US 2010/0207452. This patent application discloses a mobile electrical energy providing system comprising solar panels which can be folded, rotated and moved up and down automatically (motor-driven, computer-steered), a wind mill which can be rotated and moved up and down automatically, a fossil fuel generator, and batteries.
The batteries are energy-providing means which produce electricity from stored chemical energy. It seems that in US 2010/0207452, the batteries can only be recharged by the electricity produced by the solar panels, and not by the other means. Many of the disclosed systems can work together in an array. The system can be connected bidirectionally to the power grid, i.e. the system can extract electrical energy from the power grid and transfer it to the user, but can also transfer surplus electricity produced from the wind and solar energy to the power grid. However, disadvantageously, it seems that the batteries cannot be recharged by the electricity produced from wind energy, from the fossil fuel or from any other means. Obviously, this can lead to problems when there has been no sunshine at all, and the wind blows intermittently. During a wind-less period, the batteries can become depleted after which electricity can only be generated by the fossil-fuel generator. If the fossil fuel is depleted, the system can only provide electricity during windy periods, but has no way of providing electricity during windless periods. If the batteries could be recharged by electricity produced from wind energy, windless periods could be bridged, i.e. electrical power could be provided for during windless periods, by the energy stored in the batteries during windy periods. Furthermore, when the mobile system as disclosed in US 2010/0207452 has been e.g. indoors and/or unused for a while, it is possible that the batteries are depleted already before the system is put to use. This can happen, e.g. when the system has been in the garage for a while without being connected to the power grid, and when the solar panels have not been deployed for a while, hereby drastically reducing the electrical power storing and/or providing capacities of the batteries. When the system is then moved out of the garage and is transported to a remote area without sunshine or at night, the electricity supply depends totally on wind energy and fossil fuel, i.e. when all fossil fuels are burnt and there is no wind, one does not have battery power because the batteries were depleted already.
The present invention aims to improve on the system of US 2010/0207452 by providing a mobile system which can provide electricity and which comprises batteries that can be recharged using wind energy, solar energy, energy stored in fossil fuel, kinetic energy or a combination thereof.
Thereby, the present system comprises
- one or more batteries;
at least one means of extracting electricity from one of the following energy sources: solar energy, wind energy, energy stored in fossil fuels; a dynamo system which is connected to one or more wheels or axes of the mobile system and which can produce electricity from the kinetic energy of the mobile system when it is being towed by e.g. a car or truck.
Furthermore, the system is designed such that the batteries can be recharged by the electricity produced from any of the energy sources for which the system has extraction means, e.g. if the system has photovoltaic cells, a wind mill and a dynamo system, the batteries can be recharged by the electricity produced from solar energy, wind energy and kinetic energy of the mobile system. It is clear that with such a system, the batteries are at least partially charged when the mobile system arrives at its remote location, and that the batteries can be recharged using wind energy, in contrast with e.g. the prior art system of US 2010/0207452.
The invention thereto aims to provide a simple, robust, cheap and ecological mobile electrical power system. Hereby, electrical energy can be produced from wind energy solar energy, energy stored in fossil fuels and/or kinetic energy. This electrical energy can be stored in the batteries and can be simultaneously and/or subsequently delivered to the user in the form of AC or DC electricity. Therefore, when more electricity is needed than can be provided for from solar energy or wind energy at a certain time, the batteries can provide the extra energy needed. As soon as there is any surplus energy, the batteries can be automatically recharged.
The present invention (WO2012007444) provides a mobile system which can be a motorized vehicle or which can be towed by a motorized vehicle such as a car or truck, for generating and providing electricity; said mobile system comprising a mobile platform; said mobile system also comprising collecting systems, a converting unit and storage means attached to said mobile platform.

No. 6,293,231 to Valentin (2001), U.S. Pat. No. 7,011,051 to the same inventor Epshteyn (2006), U.S. patent application “Universal hybrid engine, compressor and pump and method of operation” Ser. No. 11/110,109 (filing date Apr. 20, 2005) to the same inventor Epshteyn, U.S. patent application “Monocylindrical hybrid two-cycle engine, compressor and pump, and method of operation” Ser. No. 11/373,793 (filing date Mar. 10, 2006) to the same inventor Epshteyn and U.S. patent application “Monocylindrical hybrid powertrain and method of operation” Ser. No. 11/637,577 (filing date Dec. 12, 2006) to the same inventor Epshteyn.
While these devices fulfill their respective, particular objective and requirements, the aforementioned patents do not describe the continuously variable displacement monocylindrical hybrids integrate powertrain and method of operation for providing compact design with superefficient functions, increased specific power while minimizing engine size and fuel consumption, and hybrids activating and deactivating jointly with total energy recuperation.
The modern powertrains has the following disadvantages:
(a) The monocylindrical hybrid powertrain do not provide entire range of the vehicle engine power control by continuous alteration engine displacement.
(b) The monocylindrical hybrid engine, compressor and pump displacement alteration range is insufficient to keep the minimum specific fuel consumption of the entire range of the vehicle engine power change.
(c) The monocylindrical hybrid engine, compressor and pump displacement alteration range is insufficient for providing constant mean effective pressure of the engine during entire range of the vehicle engine power change.
(d) The monocylindrical hybrid powertrain do not utilize the total energy recuperation process.
(e) The monocylindrical hybrid powertrain do not achieve the acceleration magnitude of standard car and simultaneously utilize considerable smaller engine size.
(f) The monocylindrical hybrid powertrain do not utilize the maximum potential of it extremely small size.
(g) The monocylindrical hybrid hydraulic system of the engine and compressor pistons return stroke is complicated and expensive.
(h) The monocylindrical hybrid do not prevent side forces causes the pump plunger and axial rod interaction with inclined lever.
(i) The monocylindrical hybrid do not utilize the potential possibility of extremely high balancing quality of the engine and compressor pistons.
Therefore, it can be appreciated that there exists a continuing need for a new and improved super efficient hydraulic hybrid powertrain providing (in accordance to US2009032317 A1 ) joint operation of the two monocylindrical hybrids having different maximum displacement and recuperation system having better specific data, lesser size and cost than widespread automotive engine and automatic transmission.
A much more effective hydraulic car system is described in our issued patent BG 65480 B1.

Advantages of two-seat hybrid / electric car
Invention herewith described refers to the small electric and hybrid cars that as a single entity has two seats and with them are transported people, goods and commodities same as with any passenger car with two seats. The small tandem car has a front seat behind the wheel for driver and a rear seat behind the front seat is for another person, commodities or goods and because of the fact that the small electric car can be driven on the bicycle path and in places where other traffic cannot it is suitable for shopping, visiting, for goods and mail delivery.
The small electric/hybrid car has two tandem seats. The front seat and the rear seat are mounted on one floor, which makes one unit so that the small car is a single entity with two seats. However, the rear seat can be produced separately, apart from the front seat with its adjusted floor that the rear seat is attached to and the floor lies on two wheels – on the left wheel and on the right wheel and that is why the rear part with the rear seat produced as a separate entity, is the essence of this invention because when it is with its front attached to an electric wheelchair, which has only one seat or to any electric cart with only one seat, it becomes an electric vehicle with two seats. Urban zero emission car.
The small electric car instead of two front wheels has only one front wheel, which is easy to operate by the steering wheel the same as a bicycle or a motorcycle and it reduces costs of the entire vehicle because a complete front wheel does not have to be bought as well as the parts and less and do not buy it parts and control system necessary when there are two front wheels and the small electric car has two middle wheels in the middle – the left middle wheel and the right middle wheel and at the rear part there are two rear wheels – the rear left wheel and the rear right wheel and both rear wheels and can rotate in different directions.

Plug-in hybrid car solar charger of smart grid
Solar energy potentially provides the answer to global energy needs. In ten hours the Sun provides the Earth with more energy than is contained in all proven oil reserves. Even though the amount of solar power theoretically available far exceeds most, if not all, other energy sources (renewable or not), there remain practical challenges to utilizing this energy.
In general, solar energy remains subject to a number of limitations that have kept it from fulfilling the promise it holds. Harnessing this energy in a cost-efficient manner is one of the major impediments to the more wide-spread use of this energy source.
A low cost upgrade solution to increase the solar energy production is to attach mirrored reflectors to the solar PV panels – see the picture. To avoid PV panels overheating in hot days the movable reflectors are used.
Today, across the world there are open-air car parking spaces that are exposed to the elements. In many such car parks attempts are made to provide shade for the individual cars through fixed car port roofs.
The present innovative solution address an important aspect of efficiently harnessing solar power by providing a system that increase harnessing of solar energy by providing additional sun light onto solar PV energy panel’ surface.
Such systems may incorporate shaded parking roofs, photovoltaic generation of clean power, and use of the solar energy so generated to recharge plug-in hybrid and electric vehicles parked there under, as well as mechanisms for returning generated power back to the electric utility’s so-called power smart grid and/or for other more immediate use or storage.
Cable store for an electric charging cable of a hybrid or battery electric vehicle , comprising a rotatable drum onto the circumferential surface of which the charging cable can wound
The development and construction of high energy efficient EV and hybrid cars base on our issued new patents BG 65421 B1, BG 65420 B1, BG 65480 B1.
The enegy plus buildings as a part of the smart grids for recharging of car batteries based on our issued new patents BG 65691 B1 и BG 65666 B1. For data exchange in real time for different needs of the smart grids can use method and facility disclosed in our issued new patent BG 65248 B1.
The here presented invention relates to a cable store (1) for an electric charging cable (2) of a hybrid or battery electric vehicle (3), comprising a rotatable drum (4), onto the circumferential surface (4a) of which the charging cable (2) can wound. In order to design the cable extraction and the cable winding to be comfortable while the cable and the cable store have a long service life, a groove-like guide profile (P) is formed on the circumferential surface (4a) of the drum (4). Said guide profile at least partially accommodates the charging cable (2) and extends around the outside of the drum (4) in the form of a helix.
Why Electric and Hybrid vehicles offer a unique energy efficiency ?
Electric vehicles are the simplest mechanical transportation.
Set of invention relates to electric train car control devices for drive wheels motor inverters control.
It is a front driven car (see video) with two separate controlled hub wheel electric machines. They operate at both modes as motor and as generators. As generators they operate in regenerative braking mode.
Each proposed control device comprises control unit including first estimation unit connected with limitation unit, second estimation unit connected with output signal processing unit.
Besides, control unit comprises switching unit connected with first and second estimation units, and process control unit connected with second estimation unit and output signal processing unit. Control unit generates magnitudes of instruction of target torque for multiple motors to kill drive wheel slippage state proceeding from drive wheel motor rpm. Estimation unit defines drive wheel slippage state proceeding from deviation of speed and acceleration from preset thresholds.
Limitation unit limits decrease in magnitude of instruction of preset torque fed from outside in compliance with the result of estimation made by first estimation unit. Second estimation unit defines is axial speed acceleration exceeds first threshold magnitude. Output signal processing unit outputs torque instruction magnitude processed by limitation.
Several technical car solutions are based on issued patent BG 65421 (B1). The car battery is charged by solar PV modules. The modules are boosted by flat mirror reflectors which increased power performance of the solar PV modules, by traveling and by all day parking, as well.
Electric vehicles offer a unique driving experience. With their low center of gravity, most electric cars, offer superb handling as well as rapid initial acceleration. Electric motors offer almost continuous torque even at lower speeds. This allows a vehicle to do things that conventional fossil fuels vehicles can not do. For example, if you were to drive up to a street curb with a conventional gasoline powered car, stop and then try to climb the curb, you would have to rev up the motor and only then would you be able to drive over the curb. With an electric vehicle, you would be able to climb the curb with out any real effort.
