How to achieve the energy independence by reducing consumption of petroleum and natural gas
Enegy plus buildings constructed by our issued new patents BG 65691 B1 иBG 65666 B1. For data exchange in real time for the needs of the smart grids and other general applications can use method and facility disclosed in our issued new patent BG 65248 B1.
With the continuous reduction in the reserve of petroleum and natural gas, the electric vehicle that is driven by electric motor is becoming more and more popular. Electric vehicle (EV) is a transportation vehicle propelled by electricity. When the capacity of the rechargeable battery of the electric vehicle is low, the rechargeable battery of the electric vehicle is required to be charged. The electric vehicle generally uses a power outlet or a proprietary charging station for charging, which will last for several hours. Many charging service providers for electric vehicle install electric vehicle networks in the United States, Europe, Australia, Japan, and Singapore to provide the electric vehicle of contracted members to be charged or be replaced with a new rechargeable battery. As to the billing method and the configuration of the charging station, numerous technological solutions have been proposed to meet the consumer’s needs. An example of such technological solution is given in U.S. Patent Publication No. 2009/0177580 which claims the method for collecting electric vehicle power consumption tax, and in U.S. Patent Publication No. 2009/0174365 which claims a network-controlled charging system for electric vehicle. Thus far, however, the contemporary charging system for electric vehicle only provides a power converter module, an electric meter, a simple user interface to allow the consumer to control the start and the end of the charging operation to the electric vehicle, or allow the consumer to proceed with user identification or price calculation by the provision of a network module and a communication interface. Hence, the contemporary charging station can not provide overall charging efficiency control for a single charging station or a group of charging stations. Either, the contemporary charging station can not provide adaptive charging service for charging station.
The major aspect of the invention is attained by a vehicle charging system, which includes a power grid; at least one charging station connected to the power grid through an electric transmission interface for receiving a first power from the power grid and converting the first power into a second power for charging an electric vehicle; and a management center remotely connected to the at least one charging station through a network for recording and managing members affiliated to the vehicle charging system and the charging preferences and charging characteristics in connection with the charging service provided for the electric vehicles of the members, and recording the fee particulars of the at least one charging station. The at least one charging station includes a socket breaker for controlling whether the at least one charging station is allowed to charge the electric vehicle. If the at least one charging station is determined to be disallowed to charge the electric vehicle, the socket breaker will open to shut down the power supply for the socket lock mounted on the charging stand of the electric vehicle, thereby unlocking the socket lock. Therefore, the at least one charging station stops charging the electric vehicle. In addition, the at least one charging station includes a power module for receiving the first power and converting the first power into the second power for charging the electric vehicle, and an adaptive charging control circuit for issuing charging commands according to the commands indicative of the demands for the electric energy of the electric vehicle, thereby controlling the charging operation of the electric vehicle. The at least one charging station further includes a power manager for managing the power module according to the charging commands indicative of the charging demands and issued by the adaptive charging control circuit or according to the loading of the power grid, thereby regulating and limiting the charging current provided for the electric vehicle.

How to augment solar PV generation by flat mirrored reflectors ?
New patented down road (highway) Solar Power Plant with Fixed Reflector Augmented PV Modules and wind turbines for battery charging of electric cars and plug-in hybrid vehicles – see video.
The 2011 Chevy Volt, primarily an electric (or hybrid) vehicle is advertised as requiring 10 to 12 hours of charging at 110 volts. If the charging current is between 15-30 amperes of current @ 110 volts, the power is on the order of 1650 to 3300 watts per hour. If the charge is 10-12 hours, one can multiply by the number of hours to produce the kilowatt hours. While charging is available to some people in their homes/garages, it presents a problem to apartment dwellers and to people who do not have access to a charging system. Accordingly, making charging systems available through parking meters or charging stations is highly desirable.
Remote power stations may be useful to supplement or as an alternative to the home recharging concept. Solar power does not require the installation of power lines for supply of power to remote charging stations.

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.
How to manufacture cheap solar PV panels ?
In the manufacture of solar panels, normally a sandwich build up (also referred to as sandwiched bodies or lay-up of solar modules or photovoltaic modules) is built essentially at normal room conditions. This sandwich build up comprises a glass plate as base plate. A first layer of plastic foil is placed on the base plate on which a network of solar cells is placed, and the solar cells are covered by a second layer of plastic foil on which a cover layer is laid.
The present invention incorporates effective structural indices for a simpler, cost effective, secure, robust, reliable, and environment-friendly operation.
The present invention provides a method for producing a solar panel built up of a plurality of layers, wherein at least one layer is pre-heated and put together under vacuum or gas atmosphere with at least one other layer.
In another aspect, the present invention provides a solar panel (module) production device in which a first side wall and a second side wall of a working chamber are movable relative to each other. A seal, preferably an elastic seal, may be provided between the side walls of the working chamber so that in a first relative position, the working chamber is closed and may be either evacuated or have a gas atmosphere established therein. As the side walls of the working chamber move to a second relative position, materials inside the working chamber may be brought in contact with each other. The device may have processing chamber that may be evacuated and/or be filled with a gas. Means for holding the base plate are provided along with means for controlling the temperature in the working chamber. The movable support is capable of moving in a direction of the sidewall.
